Patent JP-H08126398-A (JP)
Title: Automatic voltage regulator for synchronous generator
Inventor: ITO HITOSHI
IPC: H02P9/38
Filed: 1994-10-26
Abstract: PURPOSE: To stabilize the control through simple circuitry by converting the output current from an exciting power supply into a DC voltage, multiplying the DC voltage by a shunt ratio, detecting the variation amount of the product, adding the variation amount to a terminal voltage and inputting to a control amplifier. CONSTITUTION: The inventive automatic voltage regulator is different from a conventional one in that a CT 17 to detect the exciting current is disposed on the power supply side of a shunt thyristor and detects the current value of an exciting power supply. An analog switch(SW) 21 full-wave rectifies the sine wave output from a current value DC conversion circuit 18 and turned ON/OFF depending on the output from a comparator 16. Consequently, the output signal from the SW 21 has a waveform identical to that of the exciting current. Operation of the SW 21 is similar to the operation for multiplying the signal of exciting power supply current by a shunt ratio. Since such control is employed, characteristics similar to those of a conventional AVR can be obtained without requiring any special CT.

IPC: G11B7/085
Filed: 1990-10-02
Abstract: PURPOSE:To realize the loading/unloading of a cartridge as against a device mainbody without the need of the vertical shift structure of the cartridge by retracting an objective lens in a prescribed standby position by means of the operation of a driving means which vertically moves the objective lens as against an optical disk for focus control. CONSTITUTION:When the cartridge 17 is inserted into the device mainbody 10, a sensor 19 detects the insertion of the cartridge 17 and transmits an on- signal to a control means 20. The focus actuator 21 of a second optical head 15 retracts a bobbin body. Thus, the objective lens is fixed in a direction getting far from the optical disk 18 and it can be moved without being abutted on a spindle motor 12 in the optical disk 18. When the hub of the optical disk 18 reaches a chucking part 13 just above the spindle motor 12, the hub is attracted, the cartridge 17 descends and it is set in the prescribed position of the spindle motor 12. Thus, the smooth loading/unloading of the cartridge as against the cartridge device mainbody can be realized without the need of the vertical shift structure of the cartridge.

Title: Operation controller for elevator door
Inventor: ISHIGAMI KUNIAKI
IPC: B66B13/14
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To positively prevent a speed detector from detecting malfunction erroneously, for higher operating efficiency by stopping a torque command when such a condition that rotational speed is zero continues for over a fixed period, and determining that a speed detecting means is normal when detected that the rotational speed is not zero at the time of stopping the torque. SOLUTION: The rotational speed of a motor 4 is converted into a pulse by a speed detector 5 and is sent to a pulse count unit 7d, where the number of pulses are counted and a counted value is sent to a CPU 7A. When the rotational speed is zero for a preset period with door stopping caused at a prescribed point, the CPU 7A involves a torque stop means which sets a speed command value sent to a pulse width modulation unit 7F and a torque command value to zero. After the prescribed period passes, rotational speed in the opposite direction is generated by the reaction where the driving force to the motor 4 is lost. It is determined as no failure in the speed detector 5 if the CPU 7A determines that the speed detector 5 detects the rotational speed in the opposite direction at another preset time.
