Measures

The noise & vibration caused thoroughly removed in blower fan mechanism in air conditioning system equipped in our new laboratory yesterday. A mechanic engineer came from the Mitsubishi company solved the problem by replacing fan motor, some rotation spots discomfort was perceived when done by palpation in one of shaft supporting bearing. As we know radial bearing sometimes makes big noise if a very small defect exists on grooved inner or outer slipping surface or on bearing ball themselves.
As my surprise, the support and stopping surface on the driving shaft was designed as to be done by E shape snap ring, how come? A thinner E shape ring could catch and set firmly on the driving shaft? Such designing method could not prevail in drawing engineers, how come? I cannot accept this kind of error of the basic designing concept! The influence of cost reduction was seen here and there inside of heat exchanging device inside.

The illumination problem was solved of our laboratory also yesterday by newly applying straight type LED lights around the ceiling corner. The evaluation would be done today in practicing scenery in the daytime and at night.
The construction of our new laboratory would be almost finished actually, so the residual payment would be done soon after the negotiation with the representative of the builder.

My body weight reduction has come to 3,5kg per a month! With all elimination of one meal a day, the rate of the desired phenomena is not so apparent, but is successfully ongoing to the toward the goal of 10kg less.

Coming Thursday is the D-day for Legal Inspection for XH200 OPEL B-Vectra at Kobe Hyogo Land Transport Office in Ohgi, so the preparation for the event must be done on this weekend. No critical damage nor defect is found in daily use, but check it much carefully, especially the exhaust muffler gas leakage, once I lost when I had come to Neyagawa Land Transport Office with PEUGEOT 205 SX over 20 years ago.

The cause of burnt chemical material smell was the frontal differential gear oil piling from drain plug, tightening ceremony is necessary or replacing metal packing oil seal? As is often the case, the aging of automobile is mainly that of rubber materials, oil sealing, rubber bushes in axle construction, or sometimes engineering plastic parts, seldom on metal ones.
