Title: Gate drive circuit for semiconductor switch element
Inventor: YAMAGATA YOSHIHIKO
IPC: H02M3/155
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To suppress the increase in turn-on loss due to the voltage drop at the gate input capacitor of a voltage driven semiconductor switch element at the time of turning on the voltage driven semiconductor switch element. SOLUTION: Between a signal amplifier 10 for supplying a gate current to an IGBT 30 and the gate terminal 33 of the IGBT 30, the serial circuit of a gate resistor 20 and a gate coil 70 is inserted. While a collector current flowing to a wiring inductance 60 on an emitter side generates electromotive force for suppressing the voltage of the gate input capacitor 34 at the time of turning on the IGBT 30, the stored energy of the gate coil 70 offsets the electromotive force, shortens turn-on time and reduces the turn-on loss. Also, in the case that the inductance value of the gate coil 70 is inappropriate and the gate input capacitor 34 is going to be charged to an excess voltage level, a capacitor 80 interposed between an emitter and a gate suppresses the excess voltage occurrence.

Title: Method for controlling operation of air conditioner
Inventor: FUJIKI HIRONARI
IPC: F24F11/02
Filed: 1993-07-01
Abstract: PURPOSE:To keep a room temperature at a desired or predetermined temperature range and to ensure a comfortable sleeping of a person by a method wherein after a set time elapses, a monitoring operation is carried out for repeating an operation or stopping of an air conditioner in response to a difference between the room temperature and a set temperature. CONSTITUTION:As a cooling operation or a heating operation is carried out, a good- night timer is set when a person goes to bed, a set temperature is gradually increased and subsequently this good-night operation is continued until a set time of the good- night timer elapses under this state. Then, upon elapsing of the set time, the good-night operation is stopped and the monitoring operation is started. This monitoring operation is operated such that if the room temperature is increased by 1.5 deg.C, for example, than the set temperature, the good-night operation is started again, thereby as the room temperature is decreased by 2 deg.C than the set temperature, the good-night operation is stopped. This good-night operation and the stopping operation are repeated, thereby the room temperature during the monitoring operation is maintained within a range between +1.5 deg.C of the set temperature and -2 deg.C, wherein upon elapsing a predetermined time, the monitoring operation is stopped. During a heating operation, it is substantially similarly controlled in an opposite direction.

Title: Detector for angle of rotation
Inventor: MURO HIDEO
IPC: G01B11/26
Filed: 1986-08-08
Abstract: PURPOSE:To obtain a detector with high detection accuracy by assembling and fixing a light receiving element while shifting it from its center to the optical axis of a light emitting element by specific distance, and making the light reception output of the movement distance of a slit continuous. CONSTITUTION:The photodiode array 13 is assembled and fixed while shifted from its center to the optical axis A of the light emitting element by the distance (x) in a dark direction B. Consequently, a light reception part 13A1 on one terminal side turns on when the edge E1 of the slit 15 moves by distance a' after passing it. The light reception part 13A10 on the other end side, on the other hand, turns off when the edge E2 of the slit 15 moves by distance b' after passing it. In this case, the edges E1 and E2 cut of flight with the largest angle of diffusion and the light reception parts 13A1 and 13A10 become equal in the distance of OFF operation, so that they turn off at the same timing. Therefore, a continuous light reception output is obtained from the movement of the slit 15 and the high accuracy of the detection of the angle of rotation is realized.

Filed: 1980-12-27
Abstract: PURPOSE: To automatically operate motor stopping means, by providing means for detecting presence of a flow of pressure oil in an main pipe line through a throttle valve and operating the motor stopping means when absence of the flow is detected.  
     CONSTITUTION: In case of returning a control lever of a pilot valve 8 to a neutral position, a pipe line to a brake device 20 is communicated to a tank by a selector valve 14. However, at this time, suction side pressure of an oil hydraulic pump 1 rapidly rises to operate a control valve 11, then a servo valve 10 can not be reset immediately to its neutral state and remains in a selecting state. Here a flow in a main pipe line causes a pressure difference before and after a throttle valve 19, and a selector valve 15 is selected, then pressure oil of an oil hydraulic pressure source 17 is guided to the brake device 20 to release its operation, when a motor 2 substantially becomes a stopping state, the pressure difference before and after the throttle valve 19 is lost, then a selector valve 15 is returned to the neutral, thus the brake device 20 can be operated.

IPC: G06F13/37
Filed: 1990-07-17
Abstract: PURPOSE:To form a multiprocessor system without providing a common controller by setting the microprocessors of ranks lower than its own one in the halt states temporarily with control of a register at an access of a common bus and acquiring the exclusive right. CONSTITUTION:When a high rank microprocessor P1 produces a halt command to a lower rank microprocessor P2 via a register R1, the P2 transmits the halt command to the next microprocessor via a logic circuit D2 and a halt control line L2. Thus all lower rank microprocessors are set in the halt states, and the external bus of each microprocessor is electrically turned off an then electrically cut off from a common bus BO. Therefore only an external bus B1 of the P1 is connected to the bus BO. Thus it is possible to form a multiprocessor system without having any complicated bus control using a controller.
