Patent JP-H0843266-A (JP)
Title: Automatic vehicle-driving device
Inventor: SHIMOZONO AKIRA
IPC: G01M17/007
Filed: 1994-08-02
Abstract: PURPOSE:To provide an automatic vehicle-driving device which can make the front end sections of pedal operating actuators to be brought into contact with the surfaces of the pedals of a vehicle in the optimum state. CONSTITUTION:Since pedal operating actuators 4a-4c are supported by a supporting frame 3 so that the actuators 4a-4c can swing around the front end member 3A of the frame 3, the front end sections of the actuators 4a-4c can move (swing) in the vertical direction following the circular-articulate movement of pedals 12a-12c even when the pedals 12a-12c make the circular-arcuate movement around prescribed fulcrums when the pedals 12a-12c are operated. Therefore, the coming-off of the front ends of the actuators 4a-4c from the surfaces of the pedals due to unreasonable forces acting on the front end sections can be prevented. In addition, the actuators 4-4c are enabled to cope with various kinds of pedal arrangements by making the actuators 4a-4c adjustable in lateral position by means of a lateral position adjusting knob 8a and, at the same time, supporting the actuators 4a-4c by spring mechanisms in gear cases 21 so that the front end heights of the actuators 4a-4c can be adjusted by changing the set positions of the spring mechanisms with vertical position adjusting knobs 7.

Title: Fuel injection device of engine
Inventor: TSUKAHARA HIROAKI
IPC: F02M45/04
Filed: 1989-07-12
Abstract: PURPOSE:To accomplish a high precision fuel injection device with less dispersion by furnishing an opening/closing valve, which is set to a valve opening pressure higher than the valve opening pressure for a fuel injection nozzle, at an accumulator chamber communicating to a plunger chamber, and simplifying setting of the pilot injection amount. CONSTITUTION:When elevation of a plunger 13 blocks a fuel supply hole 21, the fuel in a plunger chamber 20 is pressurized to raise the fuel pressure. Because the valve opening force on the nozzle 11 side is set smaller than the force of a spring 34 energizing an opening/closing valve element 32, the nozzle 11 side is opened to actuate fuel injection. When further the fuel is pressurized and the pressure is raised, the opening/closing valve element 32 elevates against the action of the spring 34 and separates from the valve seat of an accumulator chamber 30, which causes flowing-in of the fuel in the plunger chamber 20 into the accumulator chamber 30. This sinks the fuel pressure supplied to the nozzle 11 side, which causes stop of the injection. This stop lasts until the accumulator chamber 30 is filled with fuel and the valve opening pressure on the nozzle 11 side is reached, when the nozzle 11 side opens again to actuate main injection.

A flat face 10 for confirming the position of the end of the stylus 4 in a bending direction is formed. Accordingly, if many styluses 5 are disposed along the face 10, the ends of the styluses 5 are aligned.

Title: 3-phase inverter
Inventor: KUNISADA HIDEAKI
IPC: H02M7/515
Filed: 1980-12-24
Abstract: PURPOSE:To accelerate the constant voltage controlled response of a 3-phase inverter and to correct unbalanced voltage to a balanced volage by comparing and controlling the average voltage of 3-phase with the respective phase voltages. CONSTITUTION:When U-phase voltage is controlled, an error between the DC voltage Vf3 produced and rectified by a rectifier 2 from the 3-phase output voltages of a feedback transformer 1 and a set voltage VPu is amplified by an amplifier 6, and is inputted to a delay circuit 7, thereby determining the firing angle for controlling the output voltage of an inverter INVu. Further, the U- phase output voltage is produced by a U-phase feedback transformer 3, is rectified to a DC voltage Vf5 by a rectifier 4. Then, an error between the DC voltage Vf5 and the output voltage of the rectifier 2 is amplified by an amplifier 5, and is applied to a DC amplifier 6. In this manner, the output voltage is balanced. The control of the unbalanced output voltage due to the single phase feedback control is sufficiently delayed in response without interference with the 3-phase feedback control.

IPC: H03M1/22
Filed: 1984-08-31
Abstract: PURPOSE:To prevent erroneous exposure of a film due to a light emitting element used for reading a code, by operating an automatic idle feeding mechanism of the film after the code recorded on a cartridge is read optically. CONSTITUTION:A rear cover of a camera is closed to turn on a switch SW1, and a high-level signal is applied to terminals (c) of monostable multivibrators OS1 and 2, and the information code on the cartridge is read by reflection-type photo diode modules 62-66 and 68-72. The output signal of the OS2 switched to the low level is switched to the high level by an inverter 16 and is inputted to a monostable multivibrator OS4 to operate it, and FFs 11-14 are reset by a short-time high-level pulse signal outputted from the OS4, and the film is fed idly by an extent corresponding to 4 frames. Since idle feeding of the film is not performed until the read of the information code on the cartridge is terminated, the first frame of the film where photographing is started is prevented from being exposed by the light emitting element.

Further, the connector which is short in the connection length or is matched in impedance is used as the method for connection to the outside. The photodetecting module which allows the high-speed signal transmission and has the high connection reliability is obtd. in this way.
