Title: Production of low loss optical fiber of plastic
Inventor: KAINOU TOSHIKUNI
IPC: C08F20/14
Filed: 1982-03-01
Abstract: PURPOSE:To provide an optical fiber of low loss by mass polymerizing a monomer of an org.polymer compd. forming a core and melt spinning the same together with an org.polymer comp. forming a sleeve than covering the fiber immediately with an org. polymer compd. having excellent moistureproof property. CONSTITUTION:The optical transmission loss of an optical fiber using org. polymer compds. occurs in the higher harmonic waves or IR oscillation absorption between the carbon and hydrogen constituting the compds. Therefore, the absorption of oscillations is annihilated by substituting hydrogen with heavy hydrogen, whereby the production of a plastic optical fiber having an extremely low loss window in a visible light region - near IR light region is made possible. The substitution of hydrogen with heavy hydrogen simply necessitates deuteration of methyl methacrylate. A methyl methacrylate polymer has relatively high hygroscopicity, and in the absorption of oscillations between oxygen-hydrogen (O-H) bond occuring in moisture absorption, higher harmonic waves often appear in the window of loss, thus optical transmission characteristics degrade when a slight amt. of water exists. The optical fiber is coated with an org. polymer compd. having high moistureproof moperty immediately after the fiber is melt spun through a spinning nozzle, so that the degree of light attenuation is decreased.

Title: Method for controlling electric braking auxiliary accelerator of automobile
Inventor: SUZUKI TAKAYUKI
IPC: B60L50/16
Filed: 1995-01-30
Abstract: PURPOSE:To regeneratively charge a secondary battery with electrical enerqy when the electrical energy is generated by electric braking by setting and controlling the target charged capacity of the secondary battery lower than the rated capacity of the battery. CONSTITUTION:The charging of the secondary battery of a DC power unit E is controlled so that the battery can be charged to a target capacity which is lower than the rated charged capacity of the battery in a steady state. Therefore, when electrical energy is generated by electric braking, the electrical energy can be regenerated to the secondary battery. When the charged capacity of the battery is higher than the target value, a microprocessor incorporated in a control circuit CONT fetches the information and automatically operates a squirrel-cage polyphase induction machine I as a motor in corresponding to the stepped-down amount of an accelerator pedal while an automobile is driven in a steady state. Thus the electrical energy generated when electric braking is actuated can be effectively regenerated to the secondary battery.

Title: Control method for power steering system with motor
Inventor: IO SHINICHI
IPC: B62D5/04
Filed: 1990-02-15
Abstract: PURPOSE:To avoid wasteful energy consumption for ex. due to heat emission by sensing the situation immediately before the stroke end of a steering system, and constituting so that the assist force decreases gradually from that time to just the stroke end. CONSTITUTION:When the amount of turning of a steering wheel 1A made by a driver is large and the steering system reaches the position immediately before the stroke end, it is sensed by a stroke sensor 9, and upon amplification at a displacement amplifying circuit 15, fed to a modulator circuit 16 via a subtracting device 17. This device 17 subtracts the output value of the displacement amplifier circuit 15 from the output value of a torque amplifier circuit 14, and the error of the two is passed to the modulator circuit 16. At this time, the output value of the displacement amplifier circuit 15 is increased gradually from the position immediately before the stroke end to just the stroke end-i.e., the error fed to the modulator circuit 16 is decreased gradually-to nullify at the stroke end. This precludes application of excessive force to a stopper of the steering system along with wasteful heat emission of a steering motor 5 and a driver circuit 11.
