IPC: H02P7/292
Filed: 1980-10-30
Abstract: PURPOSE:To reduce the time in which the processing device is related to the calculation of the ignition time for the subject driving device by a method wherein the ignition time is calculated in synchronization with the power source, the time required for the calculation is subtracted from the calculated value and an ignition pulse is generated after the lapse of the remaining time. CONSTITUTION:In the circuit with which the DC motor 111 is controlled by a thyristor three-phase inverted parallel inverter 114, the signal sent from a  synchronous pulse generating circuit 120a is inputted to a digital control section 122  and a reference timer 201 is synchronization with a three-phase power source. At  the digital control section 122, an armature current Ia and a current application command LCM, an ignition time Ts in accordance with the performance mode is  calculated, and at the same time, the calculation finished time is counted using the  timer 201. Then, after the calculation has been finished, the Te is subtracted from  the Ts, and the remaining time Tr is inputted to the counter of the ignition pulse  generating circuit 123a, thereby enabling to generate the ignition pulse after the  remaining time Tr has elapsed.

Abstract: PURPOSE:To improve an operation feeling so high, by lessening an atmospheric intake into an operating chamber at the atmospheric intake side to be partitioned off by a diaphragm inside a booster shell with a throttle valve gear at the input initial stage of an input rod, and avoiding a sudden advance of a booster piston. CONSTITUTION:At the time of braking a car, if a brake pedal 37 is operated, a valve piston 12 advances forward via an input rod 11, and a valve part 13c being energized by a valve spring 16 in the wake of this piston advancement also goes forward, taking a first valve seat 101, and cuts off the interconnection between both operating chambers A and B.
