Patent JP-H03156988-A (JP)
Title: Semiconductor laser
Inventor: ANAYAMA CHIKASHI
IPC: H01S5/00
Filed: 1989-11-15
Abstract: PURPOSE:To provide a high-power or short wavelength semiconductor laser by placing an ohmic metal electrode on a protrusion of a clad, and applying a metal coating over the clad and metal electrode to form Schottky junctions. CONSTITUTION:A metal electrode 21 is in ohmic contact with a protrusion of a clad 15. The clad, including the electrode 21, is covered with metal film 22 which provide Schottkey junctions at both sides of the protrusions. The metal film has a large heat conductivity to enhance heat radiation of the clad. Since the metal film changes its refractive index abruptly at the interface with the clad 15 and does not absorb light, the clad confine light sufficiently to improve laser efficiencies. Therefore, it is possible to provide a high-power or short wavelength semiconductor laser.

Title: Sensitized body drive unit
Inventor: NISHIDO KAZUHIRO
IPC: G03G21/00
Filed: 1990-11-02
Abstract: PURPOSE:To perform contact with related equipment disposed around a sensitized belt through a deflection part by forming deflection, formed at the time of the sensitized belt being partially separated from a driving roller, in the specified position in the circumferential direction of the sensitized belt. CONSTITUTION:When a driving roller 11 is rotated in the direction of an arrow mark, a closely attached sensitized belt 10 is also rotated in the same direction. The rotated sensitized belt 10 enters into a deflection forming position held between contact members 13, 14 so as to form deflection 12 in the steady state. In this case, the deflection forming position is placed opposedly to a developing roller, for instance, so that the deflection 12 is brought into contact with the developing roller, and this contact is performed with sufficient nip width to the developing roller made of extremely hard material and also stably with extremely low pressure contact force since the deflection acts as an elastic body. Contact with related equipment disposed around the sensitized belt is therefore performed through this deflection part.

Title: Charger control circuit
Inventor: YAMASHITA MIKIHIRO
IPC: H02J7/10
Filed: 1987-11-25
Abstract: PURPOSE:To enable charging of a battery appropriately and 100 percent by changing a temperature difference to be controlled according to a change of ambient temperature. CONSTITUTION:When a battery 5 is charged by a charging circuit 3, a battery temperature also rises with the rise of a battery voltage. A voltage at point A lowers, because the resistance value of a battery temperature sensor 7 decreases according to said temperature rise. On the other hand, a voltage at point B remains to be constant, because the resistance value of an ambient temperature sensor 8 does not change unless there is any change in an ambient temperature. when the battery temperature becomes a certain value or more, the voltage at point A becomes lower than the voltage at point B and the voltage at point C of an operational amplifier OP changes from H(high) to L(low). As a result, the voltage at point D of a latch circuit 10b also becomes from H to L and transmits the signal of said voltage to a charging control circuit 4 so as to stop charging a battery 4. Therefore, rise of said battery temperature stops and the voltage at point C changes from L to H, but the voltage at point D is latched and remains to be L so that the battery is not charged again.

Title: Automobile having mis-stepping preventive device for acceleration pedal
Inventor: NAGATSUKA MASAO
IPC: B60K28/10
Filed: 1991-08-28
Abstract: PURPOSE:To prevent a mis-stepping accident by releasing fixing of a fixed acceleration pedal when a pressure sensitive switch is operated while putting the seat of the sensitive switch operated by the pressure of a heel onto the lower side floor of the accelerating pedal. CONSTITUTION:The seat 7 of a sensitive switch is fixed to the lower side floor of an acceleration pedal by a magic tape, etc., voltage is applied according to the rating of the sensitive switch, and feeble current due to ON or OFF is amplified in a semiconductor element circuit 6 to operate a solenoid 5. An accelerator is locked by the spring of the solenoid 5 because stepping the acceleration pedal without putting a heel on a floor means the error of brake operation. By the operation of the solenoid, the hole of a fitting 3 attached by the idea of an acceleration pedal connecting rod is caught by a pin, and the solenoid is operated when the sensitive switch is turned ON to release the pin from the hole. When the heel is put on the floor, the accelerator can be operated freely.

Filed: 1990-11-06
Abstract: PURPOSE:To prevent sheets from being inserted wrongly by providing a manual insertion hole with a shutter, and closing the shutter when a sheet is in danger of lying on another already inserted, while opening the shutter when the sheet is in no such danger. CONSTITUTION:A copy is detected by a sensor 148 when inserted into a main body. The sensor 148 detects the rear end of the copy and at the same time a solenoid 146 is turned off and a shutter 136 is closed. The shutter 136 is kept closed until the time required for obtaining an interval at which the copy does not lie on another ahead of it elapses, the time being longer than that required for the copy inserted to lie over a sensitized material after the shutter is closed or that required for a jam of copies or sensitized material to be detected. After this safety time elapses, the solenoid 146 is turned off and at the same time the shutter 136 is opened and the next copy C can be inserted. Accurate image formation is thus made possible and also damaging of sheets can be prevented.
