Title: Gear mechanism
Inventor: UEDA SHINICHI
IPC: G11B15/665
Filed: 1984-10-11
Abstract: PURPOSE:To prevent the state of inability of operation made switching due to collision of thread tips of gears by loosely supporting gears to the extent not allowing release of engagement of a drive gear with a driven gear. CONSTITUTION:The diameter of bearing support hole 22 of a gear 16 is designed to be larger than the diameter of a rotary shaft 23 and a clearance for permit ting fine movement of the gear 16 is provided between the bearing hole 22 and the rotary shaft 23.

Title: Amplifier circuit
Inventor: MIKAMURA YASUKI
IPC: H03F1/08
Filed: 1993-08-27
Abstract: PURPOSE:To obtain an amplifier circuit where the influence on the value of a differential output by power source noise is reduced. CONSTITUTION:A transistor 230 is arranged between a load element 222 and a power source terminal VDD and bias voltage(Vb) where VSS is defined as a reference is impressed on the gate terminal of the transistor 230. Therefore, even if the potential value of the power source terminal VDD (hereinafter referred to as VDD) fluctuates, bias voltage(Vb) does not change. Therefore, if the transistor 230 is biased to a saturation area as shown in a figure, source potential (Vs) does not fluctuate even if VDD fluctuates due to the constant current characteristic. At this time, because the current flowing in the load element 222 is constant, the voltage between the both ends of the load element 222 does not fluctuate. As a result, the potential of a positive output does not fluctuate either. Namely, in the same way as an anti-phase output, the potential of the positive output is fixed by defining VSS as a reference.

Title: Photosensitive and heat sensitive recording material
Inventor: NAKAMURA TATSUO
IPC: G03F7/11
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To ensure superior shelf stability and printing resistance by successively disposing a 1st layer having a polarity changing material which changes from a lipophilic material into a hydrophilic material under heat and a 2nd layer containing a water-insoluble and alkaline water-soluble polymer on a substrate. SOLUTION: A 1st layer having a polarity changing material which changes from a lipophilic material into a hydrophilic material under heat and a 2nd layer containing a water-insoluble and alkaline water-soluble polymer are successively disposed on a substrate. Since the polarity changing material has high polarity changing ability, the penetrating property of a developing solution is considerably enhanced, developability is less liable to change due to preservation and the polarity changing material used on the interface of the substrate prevents the lowering of developability near the substrate and suppresses a change of sensitivity due to preservation. Since the polarity changing material is used in combination with the alkaline water-soluble polymer, shelf stability is enhanced without deteriorating printing resistance and satisfactory printing resistance is ensured.

Title: Power supply for air-conditioner in electric automobile
Inventor: GOTO NAOMI
IPC: B60L1/00
Filed: 1993-08-30
Abstract: PURPOSE:To deal with the power supply voltage over a wide range by turning the voltage supply from a battery to a switching power supply OFF during OFF interval of the primary of switching power supply when an air-conditioner for electric automobile is driven with the battery voltage converted through the switch power supply. CONSTITUTION:Upon turning a switch 2 ON, a switching transistor Tr5 is turned ON through a starting base resistor 32.Consequently, a power supply Tr22 is turned ON through the Tr5 and the base resistor 23 and a voltage (e), which is equal to the battery voltage E, is fed to the primary coil 14 of a switching transformer 15. The voltage induced in a self-exciting coil 13 decreases the base voltage of the Tr5 which is thereby turned OFF. The collector voltage Vc then begins to increase up to (voltage E+voltage EP of primary coil 14). But a reverse voltage is applied to a battery 19 through diodes 25, 27 thus blocking the increase of voltage Vc. This power supply allows an air- conditioner to deal with a wide range of battery voltage.

Filed: 1992-08-11
Abstract: PURPOSE:To provide diazo photosensitive paper having high image density, high sensitivity, satisfactory surface properties free from unevenness in coating with a diazo photosensitive liq. and satisfactory preservability.
