Inventor: HARA SEIJI
IPC: C08L71/02
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a conductive rubber composition of excellent workability having less electric resistance irregularity, less change of resistance over aging, and less dependency of resistance on an applied voltage by setting carbon black to be contained to a specific number of parts by weight to specific base rubber. SOLUTION: As base rubber, epichlorohydrin-polypylene oxide-allyl glycidylether copolymer rubber is used. To the base rubber 100 parts by weight, carbon black is blended 5-90 parts by weight. When the value is less than this range, its conductivity is insufficient, and when it exceeds the range, stability of an electric resistance or dependency on an applied voltage become large, or electric resistance irregularity or unstable change over again occurs. As additives, vulcanizing agent, foaming agent, vulcanization accelerator, antioxidant, softening agent, plasticizer, reinforcing agent, filler, or the like, may be used, where those other than vulcanizing agent such as tetramethylthiuram disulfide are to be blended as necessary.

Title: High frequency power source
Inventor: KATO TSUTOMU
IPC: H02M7/493
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To exactly recognize normal and abnormal states of a high frequency amplifier at normal operation. SOLUTION: An operational amplifier 13 takes the difference between an unbalance detecting signal value Vc from an unbalance detecting part 9 of a synthesizer 4, inputted to a positive input terminal, and a power source output signal value Vp from an output detector 12 inputted to a negative input terminal and compares that difference with a set value Vo and when that difference exceeds the set value, an output stop signal is generated. When the difference between an output signal value Vc from the unbalance detector 9 of the synthesizer 4 and the power source output signal value Vp from the output detector 12 is smaller than the setting value Vo, the operational amplifier 13 generates no signal.  When the difference between the output signal value Vc from the unbalance detector 9 of the synthesizer 4 and the power source output signal value Vp from the output detector 12 is greater than the set value Vo, the operational amplifier 13 supplies the output stop signal to a high frequency oscillator 1, so that the output of a high frequency power source can be stopped.

Title: Automatic developing device
Inventor: YANATORI HIROMI
IPC: G03D3/02
Filed: 1986-09-02
Abstract: PURPOSE:To prevent overflow of a processing liquid by external oscillation or movement of a member in a tank by providing a bypass route consisting of an auxiliary tank and stop valve to the outside of a processing liquid tank. CONSTITUTION:The liquid developer in a developing tank 14 flows through a valve 61 and a pipe 63 into the auxiliary tank 65 when only the solenoid stop valve 61 is opened. The valve 61 is changed over to the shut position when the liquid developer is filled in the tank 65. The liquid level of the liquid developer in the tank 41 lowers down to CD2 and stops if the capacity of the tank 65 is adequately determined. The outflow and splashing of the liquid developer by the oscillation of the processing device do not arise in such low liquid level state. The liquid developer in the tank 65 is force-fed by a circulation pump 47 and is driven into the tank 41 when the pump 47 is started after the stop valve 62 is changed over to the open position while the valve 61 is held shut. The liquid level of the liquid developer in the tank 41 rises accordingly. The valve 62 is again changed over to the shut position and the liquid level in the tank 41 restores the original level when the liquid developer in the tank 65 is substantially eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide a center takeoff type motor assisted power steering device capable of employing a layout in common with that of hydraulic type power steering devices, and preventing offset load from being applied to a rack shaft. SOLUTION: An electric motor 11 is arranged in a position which is away from the end part 2a of a rack shaft 2 in the direction of extension of the rack shaft 2, on the side far from a pinion 3.
