Manitenances

An used replacement parts, cooling fan & motor assembly, could re-obtain the original performance of the acrylic resin polymerization light gun reactor safe. Removed defective parts looks good but the electric circuitry inside must be opened. Motor itself is assumed a non-degradable, so designed as it is difficult to disassemble without destruction of precise constructive parts inside. Also assembled tiny cooling fan looks easily breakable with all utmost concentration with fine fingers.

The wooden plate for bicycle passing on the steps just in front of the entrance for by laboratory is unstable, so some fixation method have to be applied as a counter-measure. An iron plate parts is prepared for fitting on the grating on the ditch with bolts and nuts. This is a today's task for me, as an any dangerous equipment must be counter-measured as soon as possible if I feel it troublesome.

Lighting on a darker spot in the files storage room have to be counter-measured also, some special lighting method was considered, because of the difficulty to set additional lighting device at adequate position. Light Emission Diode system with lower electric power consumption has widest way spread into any direction in combinations with sophisticated sensor devices. The result of this work would be described later.
