Title: Reluctance motor
Inventor: TAKAMI HIROYUKI
IPC: H02K25/00
Filed: 1988-02-23
Abstract: PURPOSE:To perform self-starting of an apparatus from anywhere by providing coaxially a first rotator fitted with two rotors deviating 1/2pi in electrical angle from each other and a second rotator having the same structure as said first rotator and deviating 1/4pi in electrical angle therefrom. CONSTITUTION:Exciting coils 6, 7 are wound round salient poles 4, 5 as many as pole teeth 1, 2 of stator 3 to form a first rotor part 8. A second rotor part 9 deviating 1/2pi in electrical angle from said first rotor part 8 and having the same structure as the rotor part 8 is formed of salient poles 4'. 5' and exciting coils 6', 7' to constitute a first rotator 10. A second rotator 11 having the same structure as the first rotator 10 is coaxially fitted on the shaft 16 by deviating 1/4pi in electrical angle. In this manner, the dead center disappears, because any parts having smaller torque are supplemented by said constitution so that said rotor can be surely self-started from any position.

Title: Protecting device for thyristor against overvoltage
Inventor: KOBAYASHI ATSUO
IPC: H02H7/12
Filed: 1981-03-24
Abstract: PURPOSE: To decrease the required number of serially connected thyristor bulbs to be protected by a method wherein a by-pass is provided in parallel with a nonlinear resistor a section whereof can be short-circuitted.  
     CONSTITUTION: Arresters NR1 and NR2 are nonlinear resistors while SR is a by- pass composed exemplifiedly of a diode. Application of a forward overvoltage to the thyristor causes a short-circuit in the nonlinear resistor NR2 and only the forward direction protection level is selectively lowered. Accordingly, arresters are obtained that keeps within allowance the leak from a constantly applied voltage, and the protection level against a forward overvoltage at VP 1  and that against a reverse voltage at VP 2 , the difference in levels determined by polarity. Arresters are thus obtained wherein the protective level against a forward voltage is lower than that against a reverse voltage. The thyristor device forward direction withstand voltage being lower than the reverse direction withstand voltage, the required number of the serially connected thyristor bulbs to be protected can be lessened.

Title: Lamp irradiation angle adjuster
Inventor: HIDA TSUNEO
IPC: B60Q1/076
Filed: 1983-03-14
Abstract: PURPOSE:To reduce electronic circuit elements thus to eliminate protective countermeasure for electric elements by performing forward rotation, stopping and reversing rotation of actuator selectively by means of combination of plural segment type switch of lamp inclination angle adjusting mechanism and manual operation chip. CONSTITUTION:Upon rotation of chip 41 by one step to the right, selector 43 for inclination angle indicating switch 40 will contact with contactor 42n while 44 with 442-443. Here a feedback switch 9 is grounded because the selector 9a is contacting with a contactor N to rotate a motor 10 forwardly with positive voltage to a resistor R1. At the same time, the selector 9a will also rotate rightward to contact with a contactor 21 and continue rotation because the selector 44 is separated from the contactor 441, and when the selector 9a is separated from the contactor N, the motor 10 will stop. Reverse rotation of motor is performed similarly. In such a manner, inclination of lamp can be set to desired angle without employing electric element such as IC.

When it is informed by the device 14 that the reading data are the line feeding, the page feeding or the other matter, the device 11 executes the input processing of the next reading data by returning to an initial operation. When it is informed that the reading data are the line feeding or page feeding, the activation of the KANA/KANJI conversion is loaded to a KANA/ KANJI converter 15. Even when the converting/next candidate instructing key of the device 12 is operated during the reading input, the device 11 loads the activation of the KANA/KANJI conversion to the device 15.

Title: Device for decreasing processor overhead
Inventor: MAIKERU HORUTO
IPC: G06F9/34
Filed: 1995-02-08
Abstract: PURPOSE: To reduce the overhead of a micro processor by adding hardware to the register file of an external device and executing logic operation. CONSTITUTION: The micro processor writes a value in a read mask 302 and sets the access mode RAT-SEL bit of the read mask 302. The RAT-SEL bit selects the operation mode against bit access type logic 314. Thus, the data value for a write operation is loaded on a write data latch 304. When the read mask, a write data latch or an access mode change, one instruction cycle is required for executing the operation. When predicted interruption occurs, or at the time of an operation when time that interruption repetitively occurs draws near, the read mask and the data value are loaded before interruption occurs. Thus, multiple instruction cycles can be reduced to one instruction cycle.
