This industrial oil is based on "AO-oil," the stabilization technology of watch lubricating oil. The plant-derived hydrocarbon is applied to this industrial oil instead of the synthetic hydrocarbon PAO. The plant-derived substance is also adopted to the functional additives which are necessary to industrial oil. Cyclic regeneration is enabled by combining the adsorption and distillation process. 95% of this “AO-industrial oil” is composed of the base oil. At least 3.1 kg of CO₂ is absorbed to produce 1 kg of plant-derived hydrocarbon base oil. On the other hand, about 2.7 kg of CO₂ is generated for the synthesis, storage and transportation of the oil. As a result, -0.35kg of CO₂ can be accumulated since the amount of CO₂ absorbed to produce 1kg of base oil exceeds it generated in the production sequences. Therefore, a greater environmental effect can be expected by cyclic regeneration of this plant-derived AO-industrial oil.

  Carbon fiber reinforced plastic (hereafter abbreviated as CFRP) is lightweight and has high strength and has been put to practical use in aircraft fuselages, supercar bodies, and wind turbine blades. In order to reduce the weight of the bottom, attempts have been made to use CFRP for leaf springs for bogies and coil springs for automobiles. As the coefficient of thermal expansion of CFRP is almost zero, it is expected to be a precision spring. As a molding technology, we developed a method of manufacturing a CFRP coil spring with a silicone rubber mold using a carbon fiber cloth. Coil spring constant was 7.0 N/mm.

  We have developed a new solar chronograph watch, Cal.8A50. This watch is equipped with four independent dials and corresponding measuring hands, allowing stopwatch measurements in 1/100 second increments. When measuring with a stopwatch, each measuring hand moves at high speed to display the measured time. The GEAR BOX structure provides an independent dial layout and high-speed movement of multiple hands. The special drive system suppresses the drop in battery voltage during high-speed movement.
