Title: Current control type pwm inverter
Inventor: MINAGAWA TATSUO
IPC: H02P27/08
Filed: 1985-03-28
Abstract: PURPOSE:To automatically regulate to a suitable value a switching frequency in response to a noise level and a timbre according to the operating states from low to high speed operations by automatically regulating the hysteresis width of a comparator in response to the motor speed. CONSTITUTION:When the speed of an induction machine IM is lower than the speed set in a speed detector NH, an analog switch AS is opened, and the hysteresis width of a comparator COM is regulated to a wide value by the ratio of resistors R1 to R2. On the contrary, when the speed of the machine IM is higher than the speed set in the detector NH, the switch AS is closed to regulate the width to a narrow value of the ratio of the resistor R2 to the resistance R of the parallel resistance value. Accordingly, the switching frequency of transistors Q1-Q6 becomes low in low speed operation and high in high speed operation.

IPC: G06F11/30
Filed: 1987-03-18
Abstract: PURPOSE:To surely detect the abnormality of a processor set at the remote side by transmitting a 2nd communication signal only with a factor of an abnormal state. CONSTITUTION:An inter-device communication means 1 sets the communication data received from the processor of the remote side at a communication register 102 and opens an AND circuit 107 for transmission of a received signal 12 after detecting the communication given to its own device via a comparator 106. A timer 2 is reset and started by the signal 12 and at the same time a communication reception factor flag 301-4 is set. When a communication receiving factor is eliminated, a communication processing microprogram start means 302 is started for production of a microinstruction which gives a stop instruction to the timer 2. In case the communication receiving factor is not eliminated even after a prescribed time, the timer 2 transmits a time-out signal 21 to a communication control circuit 105. The circuit 105 selects a communication code instructing the interruption of communication out of a code generating part 104 and produces a signal for selection of the output of said code as well as the transmitter device number and its own device number. Then the communication code is sent to a bus 01 from a transmission selector 103.

Title: Refrigerator
Inventor: KAMIMURA ICHIRO
IPC: F25B1/00
Filed: 1989-03-17
Abstract: PURPOSE:To use effectively a heat exchanger and prevent deterioration of refrigerator oil by installing a temperature detector respectively to a pipe which bypasses a vaporizer and a refrigerant outlet of said vaporizer and controlling the opening of an electric expansion valve based on a differential temperature of both the temperature detectors. CONSTITUTION:Super heat control of a vaporizer 4 detects an outlet saturation temperature T3 of a bypass pipe 5 and an outlet temperature T2 of the vaporizer 4 by temperature detectors 6 and 7 and controls the opening of an electric expansion valve 3 by a controller 8 so as to fix degree of super heat SH=T2-T3, thereby preventing an increase in pressure loss of the vaporizer 4. Therefore, subcooling of differential temperature equivalent to the pressure loss is increased in terms of subcooling control, which prevents an increase in discharge gas temperature input or the like based on an increase in high pressure. It is, therefore, possible to use effectively the vaporizer and prevent deterioration of refrigerator oil due to an increase in discharge gas temperature.

Title: Front wheel steering control device of vehicle
Inventor: FUJITSUNA MASAMI
IPC: B62D101/00
Filed: 1993-03-24
Abstract: PURPOSE:To prevent overheat of an electric motor to be caused after the rest swing of the front wheels and reduce the energy to drive the electric motor in a device to steer the front wheels of a vehicle by the electric motor. CONSTITUTION:In a device where the target relative angle thetar between the steering wheel and the steering mechanism is set (110-160) based on the vehicle speed V, the steering angle thetaH of the steering wheel, and the steering speed dthetaH, the motor torque Ta is calculated (170) so that the real relative angle thetaa may be the target relative angle thetar, and the electric motor for driving the steering mechanism is energized and controlled (200, 240), the energizing current to the electric motor is gradually reduced (180-230) by subtracting the specified value DELTAT from the torque command value Tao to be outputted to the electric motor, if the steering angle thetaH remains constant over the specified period of time when the vehicle is stopped where the vehicle speed V becomes below the extremely small vehicle speed V1. As a result, after the rest swing of the front wheels, the electric motor is not energized for a long time to cancel the torque due to the elastic deformation of the tires, preventing the overheat of the electric motor, and reducing the energy to drive the electric motor.

Abstract: PROBLEM TO BE SOLVED: To provide a method of growing a crystal and a method of manufacturing a semiconductor device, which are capable of heavy p-type doping using a material gas which does not corrode-cambers. SOLUTION: TEGa, AsH3 and Cl2H2 are introduced into a chamber 10 by an H2 carrier gas. TEGa and AsH3 react on a heated GaAs substrate 18, thereby growing thereon a compound semiconductor crystal. During the growth of the GaAs compound semiconductor crystal, Cl2H2 is given thermal energy on the grown crystal surface and is thermally decomposed. As a result, C mixes into the GaAS grown crystal as a carrier, thereby subjecting a GaAs crystal layer to p-type doping. It is verified from experiments that the Cl2H2 gas neither produces memory effects nor damages the chamber 10. Furthermore, by using the Cl2H2 gas as a p-type doping material, an HEMT can be produced continuously within the same chamber 10, after the p-type doping process.
