Natural environment

A Shicharatombo was on the tip of the vine in my garden this morning. Generally, a Dragonfly can live in clean water, so our living environment is not so badly poisoned.
Osaka plane viewed from 300 m above sea level has some air pollution, from the standing point of view of Ikoma mountain the plane is covered with the smog, so to speak the contaminated layer.
I don't feel better to live under such a dirty circumstance at all.
Finding out an insect like that, I'm living with a living thing that prefers clean breathing air condition.
Now, the temperature of my working room is rising up gradually over 30 degree, I really envy air conditioning electric system.
Following to my distorted concept, "Live in natural circumstantial condition",  much water for drinking is prepared around myself.

Dangerous PDA watching while moving

Watching Personal Display Assistant while walking is very dangerous especially in crowded circumstance and it is called attention.
In addition, wearing earphone at the same time invites much danger, because the 2 senses of 5 ones in human being are not in function scattered for another concentrations. Not while walking but while riding bicycle or driving a vehicle, the degree of danger should be far increased at all.
In spite of such an information, my son does it while riding bicycle apologizing with special designing of earphones, it can catch also external sound.
What kind of way is remained to change his perception in this dangerous  situation, bad boy, how come?

YS 60 FS Ringed

YS 60 FS for Helicopter was obtained from Yahoo Auction at 1,190 yen the other day. My intention is to have carburetor part for the same type motor at my hand.
In spite of a lack of needle valve, the condition was good without any damage.
Ringed piston is keeping good compression and no too much used symptom was observed, probably used very little.
The drive washer thickness is reduced about 5 mm shorter, so a propeller for airplane is acceptable without any modification, the key length is cut a half. This kind of modification is the first time that I come across for YS 60 FS model.
Judging from the drive washer finish, this machining must have been processed in the factory.
Crank shaft supporting bearings, #6903 and R6Z were replaced as usual, carburetor fuel line was cleaned and diaphragm function was checked.
This lovely YS 60 side exhaust model will be burdened on an old model airplane that I modified "Head Master 60" in very near future.
As for a normal muffler for this motor would be invited that of ENYA 60 X, with a slight adjustment on the pitch for fixation.

Tiny planting

Early this morning before getting hot,  I planted 3 different colored flowers in a small plantain, it had been thrown away for long time after the tulip season.
The plantain with tiny flowers becomes the East-Northern corner of my house.
There exists Osaka Gas company's Gas meter with a safety switch that had a  problem caused by Osaka Earth Quake few days ago.
Even now there exist some incovenience of inflastructure in Ibaragi and Settsu areas.
Weather forcast tells that it'll be hot over 30 degree, so I must make effort in sever condition in my working room, probably temperature will exceed 35 degree. No cloud is observed in the sky, weak wind and fine Summer day.
I would like to stay in an airconditioned room checking my writing work.

LEXUS Premium Concert 2018

We enjoyed "LEXUS Premium Concert 2018" this afternoon at Chayamachi Umeda, an indispensable conductor was famous Sachio Fujioka as usual, of course he is the Principal conductor of Kansai Philharmonic Orchestra.
As mentioned before, he conducted Ashiya Symphony Orchestra this Spring at Nishimnomiya, he did on a Amateur players good as arranging their shoulders with a professional Orchestra, I thought at that time.
Though their remarkable improvement was apparent, the result must have been brought almost by the capability of Mr. Fujioka.
The former perception that I had was completely changed after the experience today.
The skill as a professional player has the most to with the sound itself, in addition to the sense of the conductor.
So comfortably smooth string and the fine transition to the another instrument was above words.
Played album were popular ones and an invited guest appeared on the way, vocalist with violin playing by herself while singing. Her capability and potential are also representing Superb Australian.
Without doubt, Mr. Sachio Fujioka is the second conductor to none now.

Gimbal stick & PILOT Junior

Replacement of the lubricant from ordinary Silicone grease into Carbon Graphite
in the gimbals stick construction required several change of settings, gimbals tension spring strength, D/R ratio and the value of Exponential for all the 3 channels, aileron, elevator and rudder.
All the moving wings were controlled too much under the former settings, also the neutral return spring ratios were weakened.
It proved that the slipping resistor between the lever and the pins affects all the setting condition in the gimbals stick movement.
Automatically, it does on the actual flight itself.
It might be regarded as a trifle matter at all, but piled trifles is not always trifle but is important and produces differences.

PILOT Junior is now construction preparing for the next Golden Age & Old Time meeting in next Autumn.
The power source is L.M. Cox Medallion 15 with modified front carburetor holder for ENYA 15 throttle valve. The part was made by the Lost wax casting method DIY.
As I prefer some stable operation from lo to hi rotation, I chose Medallion rather than more hi power Tee Dee 15 that has hi compression head and double Schnerle scavenging ports.

ATX PC runs away

Running away phenomena of my ATX Tower PC obliged me to maintain today.
Long thrown away machine caused Thermal Runaway after a few hours use.
The servicing method was thought to be some easy task at the beginning, but actually not, because the piled dust was combined by mold growing deep inside of the cooling fins.
Both CPU and video card were cleaned by disassembling including power supply.
At least once a year of periodical maintenance should not be ignored.
All the machinery are invaded by the invisible flying mold and Mycelium, they are one of the food chain undoubtedly. Also they can be an allergen of the heavy allergic symptoms.
Bacteria, mold and virus are sometimes inconvenient for human being, but they have the reason to exist on Earth.

Film coated "Erica"

Film coating with Oracover on "Elica" has been completed relatively smoother than usual. Simple 2 colored with Cub yellow and Purple clear to obtain the confirmation of flying attitude. Recognition for the direction of the fuselage and the main wing inclination is the first purpose while she is in the sky.
Larger main wing area might be suitable for 60 Schnurle motor, but I have chosen OS 55 AX motor with normal muffler following the regulation by Cassiopeia 70 class competition.
Nobody participating in the meeting would not bring any High wing model for F3A maneuver competition, but I do that. Mixing function would cover bad habit enough to keep straight flight while Knife Edge phase including aileron differential function establishing rolling axis. Improved controlling stick smoother function in Futaba 10J entry Tx model would be helpful.
Fully DIY designing and costructing High wing model might be outstanding among China made ARF pure stunt airplanes.
Controlling servos would be Futaba Digital 4.8V S9255 for Helicopter Rudder use.
Let's see what will happen in the competition scenery.

Aftershock this morning

We had some aftershock around 5 o'clock this morning, metal storm doors were trembling. Though I was afraid of more shock like yesterday after that, no more shock was observed.
Thanks to the desperate effort by the engineers and the retention measures, Hankyu Rail Road are now in normal operative condition for all the lines.
I would like to take Kobe line and Kyoto one this morning for the purpose of checking my working place hoping nothing inconvenient happened by the Earthquake shock.
Radio news told some miserable report that an elementary school girl was killed by a heavy block fence, sandwiched unluckily. Many flowers and bouquet were there praying for the souls.
Hanshin Awaji Big Earthquake occurred tens years ago was remembered in my mind, praying never to come back again such a miserable destruction.
Dangerous constructions and buildings are not recognized until some resultant collapse and destruction might happen.
More checking and correction by the Administration should be performed before the disastrous affair.
Repeated Natural disaster shows that our sophisticated Scientific technology cannot control natural phenomena enough to avoid any accidents.
A happy day today will not always come tomorrow.

Gas supply stopped

Recent Gas Supply meter has safety auto cut off mechanism and it was activated by the shake caused by the Earthquake this morning.
Automatically hot water supply stopped in my house, in addition bathing room has also problem, no hot water.
Thanks to the description in Osaka Gas HP, I could recover it's original function safe.
The fact that the telephone line connected with the dealer is so crowded, not a few people must be in trouble of no Gas supply.
Anyway, the natural disaster like this morning influences to many directions.
Workers and students must have some tremendous inconveniences because of stopped traffic.
My friend told me that the bridge on Yodo River is so crowed with the pedestrians unusually, and even now Hankyu Kyoto line is not activated.
Some system must had been destroyed on the rail way, I hope it would be recovered next morning with my best thanks for the desperate effort by the workers in the maintenance area.

Earthquake at Osaka this morning

Earthquake broke out this morning at Osaka area with M5.9 degree and all the traffic is out of order now. Emergency vehicles are running about with warning siren. My family must have remembered the huge Earthquake happened few years ago involving thousands of victims, Hanshin Awaji Big Disaster. The infrastructures around my living place were destroyed at that time, abominable memories.
All the railroad are stopped and some of the train did on the way with fully burdened in this commuting time zone. Not a few workers and students in the train must have influenced inconveniently.
My son took the way to go to the working place by bike without hesitation.
Probably the road traffic is crowded unusually, so I determined not to go outside today unnecessarily.
No harm was obtained in my living place but I'm anxious about my working room, many things are put and hug here and there.
I hope no damage would not be recognized when I visit there.
An unexpected affair happens any time, what must be done before the disaster occurs.

Tx stick smoothness in Futaba 10J

Improvement of smoothness on Gimbals stick in Futaba 10J transmitter has remarkably recommended by applying the carbon led powder between neutral guiding lever surface and guiding pin.
According to my experience on the shutter trigger when I disassembled Leica M3 old model, several materials were applied at that portion,  Teflon powder Microflon, 2 Molybdenum sulfate, and Carbon Led Graphite Led powder.
Carbon led graphite powder had some advantage among the materials tested especially in the condition of short distance, slow movement and relatively high pressured slipping scenery.
This same concept was applied on the transmitter gimbals construction because I had been suffered from some uneven movement phenomena in aileron, elevator and rudder stick actions. Slipping resistor changes and the stick movement transition is not always acceptable to set and keep the stick angular position when vertical flight. This is why I determined to replace the lubricating materials from ordinary Silicon grease to Carbon graphite powder.
Now I have no complaint on the gimbals stick movement in 10J transmitter as a matter of fact. Next actual flight would prove that the change of lubricant should be effective enough to compete with the other applicants who all are armed with the most sophisticated proportional system 18MZ. Defeating higher weapon with the cheaper arm is my way.
The reliability of the Radios between them are the same however cheaper it may be, so the requirement at the competition scenery is nothing but the skill of the pilot, eye sight to the moving thing and my own quick finger reactive movements.

Pure stunt model "Erica"

Fully self designed high wing stunt model is now under construction. Wing span is 1600 mm for meeting with the regulation, main wing airfoil is 17% symmetric and the thrust layout is similar with an ordinary stunt model, though "Erica" looks like just a slow flying dull high wing model, I would like to get higher score in the competition scenery with "Erica".
It looks that a high wing designing is not suitable for F3A pattern maneuver, this model would have enough capability to defeat another stunt models, most of them should be some China made ARF models.
I will take part in the competition with "Erica" just to win, not only for participating.
The power source would be OS 55 AX inviting YS fuel pressure regulated pump system. Propeller is high performance Akizuki 13-6 Glass Fiber Polyester hand made one.
Probably, every applicant would be surprised to see my high wing stunt model with laughing, and with making little of "Erica".
In order to recover my shocks caused by loosing 2 model airplanes last year, I must make haste to finish this "Erica", ASAP.

Unknown Landing Thing

A beautiful colored insect was taking a rest on the wall surface this morning, I don't know it by name and where it came from. The shape, figure and coloring of their living thing is nothing but an art. Probably the construction of the exoskeleton must be fine and the muscles, nerves and synapses are well designed inside, also it has an indispensable capability to inherent its specific Genome Information to it's next generation.
I'm looking forward to find out some suitable good coloring design to be imitated for my model airplane.
Whenever I verify designing and coloring on the natural living things such as beautiful insects and Tropical fishes, I never recognize their functional beauty without surprise.
By the way, who made this?  What's the purpose of this living thing to have appeared on the Earth? How long it's life circle would be repeated and continued? Before that, why I myself is living on the Earth, what is the necessity of Lives here? I know that our business to produce the next generation and have I my son actually. Still now I have the Question.
If I was an artist, I would try to find the way in the natural living things to establish my standing point of view.
And my critical goal would be overcoming the "Natural" by my work.
Though my desire is not well performed enough even after 68 years interval.

The 89th Ashiya Symphony Orchestra Regular Concert

The 89th Ashiya Symphony Orchestra Regular Concert was held at Nishinomiya Hyogo Performing Arts Center Grand Hall this evening and we enjoyed far more than usual, because the Conductor was specially invited, Mr. Sachio Fujioka. The sound they served was superb like a different orchestra, actually their all programs were above words. Their professional like performance was fully conducted by Mr. Fujioka probably with hard work.
The sound of strings had some ultimate balance with warm thickness and harmony, transition to the next phrase was very smooth, also the connections with another instruments were so marvelous as to satisfy the audience today.
Though I would often feel some noisy condition while fortissimo phase, I was not suffered from saturated noisy sound even once.
I realized that the sound of the orchestra is not decided by the skill of the members but is done by nothing but the sense of the conductor.
2nd program, K. Emerson & G. Lake : "Tarkus" was the best one this evening.
Mr. Sachio Fujioka is going to take office as an invited chief conductor of The Tokyo City Philhalmonic Orchestra on '19, April

Trasmettitore cardanico R / C

Sto mantenendo Futaba Transmitter, 18MZ, 14SG e 10J, quindi è possibile confrontare le loro funzioni reciprocamente. La funzione sul bastone del giunto cardanico è la prima differenza sulla resistenza di scivolamento, molto precisamente diversa ma influisce sul volo come dato di fatto. In particolare, questo tipo di resistenza viene prodotta con un movimento a distanza di 1 - 2 mm sulle superfici della leva di ritorno automatico e del perno di guida.
Il modello di fascia alta ha cuscinetti a sfere sulle parti assiali rotanti e la progettazione costruttiva ha effetto, con un movimento fluido nella costruzione del giunto cardanico.
Come esperimento di prova, ho applicato I 5-2-3 cuscinetti a sfera sul perno di guida, poi ho scoperto che il movimento nel giunto cardanico è notevolmente migliorato inaspettatamente, la scorrevolezza del modello 10J è paragonabile a 14 SG o più.
Quindi concludo che il criminale che produce una brutta sensazione sulla dose di costruzione Gimbal non esiste nel movimento assiale nell'estensione del volume, ma sulle superfici scivolose tra la leva di ritorno automatico e i perni di guida.
Il controllo dei fenomeni di collasso del bastone appare se i cuscinetti a sfera sono applicati in pratica, significa che il rinnovo e la riprogettazione della dimensione della leva di guida auto-neutra dovrebbe essere fatta.
Inoltre, una leva e due perni di guida producono le differenze di forza della molla, un lato più leggero e l'altro più pesante.
Nel caso di due leve che si legano e la progettazione del perno di guida a leva singola non ha importanza sul movimento direzionale.
Ho appena ricordato lo scenario quando ho smontato la fotocamera Leica M3 finder alcuni anni fa. Quando ho applicato del lubrificante sulla parte del grilletto dell'otturatore, nessun olio e materiale Microflon era accettabile, ma polvere Carbon-Led. Il punto in cui esistono le superfici scivolanti con pressione relativamente alta, solo la polvere di carbonio con materiale Led è efficace per ridurre il resistore di scivolamento.
Ho intenzione di applicare il materiale di grafite sulla costruzione Gimbal dopo aver rimosso l'olio di grasso messo dalla fabbrica, la cattiva sensazione sarebbe scomparsa, quindi spero.
Il rapporto risultante più tardi.

R/C transmitter Gimbal

I'm keeping Futaba Transmitters, 18MZ, 14SG and 10J, so it is possible to compare their functions each other actually. The function on the Gimbal stick is the first difference on slipping resistor, very precisely different but it affect on the flight as a matter of fact. Especially, such kind of resistor is produced in 1 to 2 mm distance  movement  on the surfaces of self returning lever and guiding pin.
High end model has ball bearings at the rotating axial portions and the constructive designing takes effect, with just smooth movement in the Gimbal construction.
As a trial experiment, applied I 5-2-3 ball bearings on the guiding pin, then I found out that the movement in the Gimbal has far improved unexpectedly, the smoothness of 10J model is comparable with 14 SG or more.
So I conclude that the criminal to produce some bad feeling on the Gimbal construction dose not exist in the axial movement in the volume extension, but does on the slipping surfaces between self returning lever and it's guiding pins.
Controlling stick collapsing phenomena appears if ball bearings are applied as a matter of fact, it's means that the renewal and redesigning of self neutral guiding lever dimension should be done.
Also, one lever and two guiding pins designing produces the spring strength differences, one side lighter and the other heavier.
In case of two levers binding and single lever guiding pin designing does not matter on the directional movement.
I just remembered the scenery when I disassembled Leica M3 range finder camera few years ago. When I applied some lubricant on the shutter trigger portion, no oil and Microflon material was acceptable but Carbon-Led powder. The point that the slipping surfaces with relatively high pressure exists, only carbon powder with Led material is effective to reduce the slipping resister.
I'm going to apply the graphite material on the Gimbal construction after removing grease oil put by the factory, bad feeling would disappear, so I hope.
The resulting report later.

A tiny art

I found out a small insect in my garden this morning with 1.5 cm length.
Very small as it was, it had an artistic beauty, however hard I might try, I would not be able to imitate it, it's functional art is far above my imagination.
It appeared in front of me overcoming many hardships, the possibility to born might have been very small.
It can fly in the sky with superior controlling and it would contribute to produce it's next generation.
It's body construction must be fine inside, the muscles are well controlled by nerves coming from it's brain. No one can make like this but the God.
It's color and pattern are above words, just fine.
I hope this living thing would last till it's Gene transfer would be done safe with coming across with a heterosexual friend.
I feel happy whenever I find out unknown living thing whatever it might be.
