IPC: H03K19/00
Filed: 1987-09-10
Abstract: PURPOSE:To reduce the peak value of a discharge current flowing from an output terminal to a ground point and a charging current flowing from a power supply to an output terminal and a through-current by supplying power through, a delay circuit and a depletion transistor(TR). CONSTITUTION:When an input signal to an input terminal 1 changes from a low to a high level, the output of an inverter 4 changes from a low to a from level with a delay.

Abstract: PURPOSE:To cover a feed delay portion of fuel as well as to make an accelerating feeling securable, by altering an acceleration judging reference value to the slow acceleration side at a time when a driving state just before acceleration is deceleration. CONSTITUTION:At a controller 20, the fundamental air-fuel ratio calculated on the basis of a suction air quantity and an engine speed to be detected by an air flow meter 3 and a crank angle sensor 24 is compensated to the rich mixture side if an opening variation in a suction throttle valve 7 to be detected by a throttle position sensor 27 is larger than the acceleration judging reference value. Hereat whether a driving state just before acceleration is deceleration or constancy or not is discriminated by reading a fuel-cut signal, and if such a decelerating state that the fuel-cut signal is outputted is discriminated, the acceleration judging reference value is set to a low value at the slow acceleration side. With this consitution, at acceleration driving just after deceleration atending upon the fuel cut, even in case a symptom of slight acceleration is indicated, fuel increment is made so as to be started.
