Title: Laser beam scan detecting device in laser printer
Inventor: ISHIKAWA HIROSHI
IPC: G02B26/10
Filed: 1985-12-20
Abstract: PURPOSE:To eliminate the possibility of malfunction even if an electrical noise is generated in the signal system of a sensor as a detecting means by leading the AND result between signals from both an electrical and a mechanical means out as the detection signal of a scan position. CONSTITUTION:A beam is made incident on a laser beam arrival position detection sensor 1 and the beam scan position is detected in the form of an electric signal and the signal of the sensor 1 is amplified by an amplifier 3 to have waveform (a). A slit 21 bored in a rotary disk 22 which rotates together with a rotary polygon mirror 13 in one body is detected by a photosensor 23, whose signal is amplified by an amplifier 4 to have a waveform, (b) wider than the waveform (a). In this case, a phase adjustment is so made that when the beam is made incident on the fitting position of the laser beam arrival position detection sensor 1, the slit 21 of the rotary disk 22 is detected by the photosensor 23. Waveform signals from both sensors 1 and 23 are ANDed by an AND circuit 5 to obtain a waveform (c).

Title: Air intake control device of internal combustion engine
Inventor: YOTSUEDA KEIJI
IPC: F02D9/02
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To provide an air intake control device capable of suppressing deterioration of the volumetric efficiency even when the engine rotational speed is increased. SOLUTION: An air intake control valve 19 to be opened/closed by an actuator 20 is provided in an air intake passage 2 on the downstream side of a throttle valve 8. An electronic control unit(ECU) 41 controls the actuator 20 based on the operational condition. In particular, when the engine rotational speed exceeds the prescribed value, the full opening/closing operation of the air intake control valve 19 is impossible when an air intake valve 5 is opened. In such a case, the air intake control valve is kept open to reduce the pressure loss even after the air intake valve 5 is closed. The pressure pulsation is generated in the air intake passage 2, and the pressure periodically becomes maximum by the pulsation. The air intake control valve 19 is closed at the timing when the pressure is approximately maximum.  The pressure in the dead space is kept high after the air intake control valve 19 is closed, and the volumetric efficiency is improved in the next suction process.
