Title: Input overvoltage protecting device for inverter
Inventor: TSUNO YOSHIYUKI
IPC: H02P27/06
Filed: 1988-02-24
Abstract: PURPOSE:To protect a transistor for a brake resistor without increasing the current capacity of the transistor by interrupting a switch when an AC power source voltage becomes overvoltage. CONSTITUTION:Power from an AC power source is supplied by turning ON a switch 2, and a motor 10 is rotated by the output of an inverter 5. When the AC power source voltage becomes overvoltage, a detection signal exhibiting an overvoltage is applied from a voltage detector 21 to an actuator 22. Thus, the actuator 22 outputs an interruption signal before it becomes a smoothing voltage of a level for turning ON the transistor 9, thereby interrupting the switch 2.

Title: Brake control method of vehicles
Inventor: TAKAOKA TADASHI
IPC: B60L3/08
Filed: 1978-04-10
Abstract: PURPOSE: To ease the shock at braking by issuing a brake easing command from a system other than ATC either before or after the brake command of ATC.  
     CONSTITUTION: ATC arithmetic circuits 3 and 4 issue the ATC brake command d and the brake easing command f when the speed c of vehicle exceeds the ATC speed restricting command a received with an ATC receiver 1. Since the brake easing command f is outputted earier than the ATC brake command, a brake easing action is started before the application of the ATC braking. The brake easing command g is held by a timer by a proper time interval after the ATC brake is released, and thus, the brake easing action remains after the ATC brake is released.

A micro-computer 3 may calculate initial disturbance values of room temperature sensors 1a and 1b when a combustion is started, stored them in a desired data memory 13. It compares the outputs of the room temperature sensors 1a and 1b with the disturbance values so as to control each of the portions of a combustion part. Then, a difference of temperature between both room temperature sensors 1a and 1b during a combustion operation is calculated, a difference of initial disturbance values is calculated in reference to this difference of temperature of both room temperatures so as to correct the detected difference in temperature. When the corrected detected temperature difference is high, there is a disturbance in a degree of heating in a room, so an amount of hot air is increased.
