Title: Pwm built-in microcomputer
Inventor: MATSUMOTO HIROYUKI
IPC: G06F15/78
Filed: 1990-07-10
Abstract: PURPOSE:To prevent the PWMs from being actuated simultaneously by executing the control so that a delay operation is executed between each PWM, when an actuation of plural pulse width modulators (PWM) is applied. CONSTITUTION:A delay operation is executed between plural pulse width modulators (PWM) 1a - 1d and this delay time is controlled. that is, the PWM 1a - 1d executes the pulse width modulation, based on a source clock inputted from a clock divider 2. Also, an enable register 3 controls the operation start and the operation stop of the PWMs 1a - 1d. In such a state, when an actuation of two or more PWMs is applied, a delay control circuit 4 executes a delay operation of the PWM by a set time so that the actuation of each PWM does not occur simultaneously even only one. In such a way, the timing by which the actuation of each PWM 1a - 1d is applied does not match even only one but is delayed, and as long as the operation is executed in the same period, it does not occur that outputs of the PWMs are varied simultaneously.

Abstract: PURPOSE:To keep the tip surface of the glow plug at high temperature at all times and consequently solve the problem of considerable ignition lag at low speed and light load of an engine by a structure wherein the tip surface of the glow plug employed in diesel engine is specifically processed. CONSTITUTION:Because the surface of the tip part 32 of the glow plug 33 is coated with oxidized catalyst 34, even when the energizing of the glow plug 33 is stopped after starting the engine, said oxidized catalyst 34 is kept at its activation temperature at all times due to the combustion heat of the engine and as well as due to reaction heat of oxidation reaction between fuel mists and the oxidized catalyst 34, the surface of the tip part 32 of the glow plug 33 is kept at high temperature. Accordingly, the fuel injected from a fuel injection nozzle 31 during compression stroke ignites and burns itself without causing considerable ignition lag even at low speed and light load of the engine. As a result, the combustion noise and vibration of the engine can sharply be reduced.
