IPC: B60N2/225
Filed: 1993-07-16
Abstract: PURPOSE:To reduce the number of part items by providing a claw coupling with a rotary member arranged to make contact with a peripheral surface concentric with the center axis of a hinge shaft and a peripheral surface eccentric from the same so as to prevent occurrence of sticking operation. CONSTITUTION:An upper arm 32 is rotatably supported on a hinge shaft 33 through the intermediary of a concentric member 34, and a lower arm 3 is rotatably attached thereto through the intermediary of an eccentric member 35. Rollers 37, 38 are fitted in a cut-out groove 35b formed in the eccentric member 35, and are made into contact with an eccentric peripheral surface 31b and an eccentric peripheral surface 31a of the lower arm 31. In this case, internal teeth 31a of the lower arm 31 and external teeth 32a of the upper arm 32 are pressed against each other so as to be meshed with each other when the rollers 37, 38 make contact with the eccentric peripheral surface 31b. When the hinge 36 is rotated by means of a handle 36, the roller 37 is rotated so as to moderate the contact force between the roller 37 and the eccentric surface, and accordingly, the meshing between the external teeth 32a and the internal teeth 31a are loosened so that the upper arm 32 is further rotated.

Title: Drive circuit for semiconductor laser
Inventor: SUZUKI KATSUAKI
IPC: H01S5/068
Filed: 1987-07-15
Abstract: PURPOSE:To enable a constant peak output of a semiconductor laser to be maintained without depending on the duty ratio of a modulated input signal, by changing an average light output command of the semiconductor laser according to the duty ratio of the modulated input signal. CONSTITUTION:A photoelectric current, which varies directly with the light output of a semiconductor laser 5, flows through a photodiode 6 composing a means A for detecting light output to be converted into a voltage by a resistor 7. The laser 5 is drived by pulses produced through a modulated signal to vary a monitoring signal for the light output. This monitoring signal is smoothed and is converted the level thereof to be output as an average light output monitoring value by the means A. On the other hand, the modulated signal is supplied to a means B for outputting average light output command through an inverter 15 to become an average light output command at a variable resistor 23. An amplifier 12 amplifies the difference between the average light output command and the average light output monitoring value to drive a transistor 2. Therefore, the light output of the laser 5 is so controlled as to correspond to the average light output command, and the peak output thereof is so controlled as to be constant without depending on the duty ratio of the modulated signal.

IPC: H04N7/16
Filed: 1994-07-29
Abstract: PURPOSE:To automatically control an RF input level in order to give a proper modulation decree to a laser diode in response to the number of channels. CONSTITUTION:An AGC circuit 20 inputs and amplifies plural amplitude modulated channel signals having the multiplexed frequency to control the gain so that the output can keep a prescribed reference level. When a laser diode 23 is driven by the signal received from the circuit 20, an optical signal having its modulated amplitude is outputted.

Title: Flow controller of fuel pump for vehicle
Inventor: ITO MOTOYA
IPC: F02M37/20
Filed: 1989-07-12
Abstract: PURPOSE:To prevent bad effect caused by generation fuel vapor by automatically controlling supply flow from the side of a fuel pump in response to change in required flow from the engine side, and thereby lessening fuel heated by the engine. CONSTITUTION:At the time of low load operation of an engine, pressure of a fuel passage 10 inside a housing 1 is lowered because set pressure of a pressure regulator is low. The pressure of a piston 3 is thus decreased, and the piston 3 is moved by a spring 5 to the side of the housing 1 so as to project a shutter 4 into the housing 1 orthogonally to the fuel passage 10. The opening area of an orifice 13 is decreased thereby so as to control transit fuel. At the time of high load operation of the engine, fuel pressure in fuel passage 10 rises since set pressure of the pressure regulator is high, to compress the piston 3 and also to pull the shutter 4 off from the fuel passage 10 of the housing 1. Consequently, the opening area of the orifice 13 is enlarged so as to increase the transit fuel.
