Abstract: PURPOSE:To enable accurate detection of air flow, by dividing a flow path area of an intake path being obtained on the basis of a throttle valve opening by a rotary speed then operating an intake air quantity on the basis of the divided value and the rotary speed. CONSTITUTION:During operation of an engine, a control unit 18 obtains the flow path area of an intake path 11 near a throttle valve 10 on the basis of an output signal from a throttle valve sensor 14 while simultaneously, obtains a flow path area of a bypath 19 detouring a throttle valve 10 on the basis of a drive control signal for commanding an idle control valve 20. Then an air flow QH under steady state is obtained on the basis of a value obtained by dividing the sum of both flow path areas, i.e. total flow path area, by an engine rotary speed obtained on the basis of an output from a crank angle sensor 15, and an engine rotation. Thereafter, a predetermined lagging coefficient is obtained on the basis of the total flow path area and the engine rotation so as to calculate an air flow Qc to a cylinder on the basis of said lagging coefficient and the air flow QH and employ in the control of air-fuel ratio.

Abstract: PURPOSE:To prevent cutting quality from deteriorating and to effectively predict the replacing time of an electrode and a nozzle by using an AND circuit inputting an output of a NAND circuit and an output of a start command circuit for an output keying signal circuit of a DC source. CONSTITUTION:In an ordinary cutting time, the output of a voltage detecting circuit 11 between the electrode and the nozzle is low, the output of the NAND circuit 10 is high, accordingly, the output of the output keying signal circuit 8 makes ON and cutting can be carried out. On one hand, when the voltage between the electrode and the nozzle comes under the detecting level, the output of the detecting circuit of the voltage between the electrode and the nozzle makes high. Since the output of the start command circuit 7 continues to be high, the output of the NAND circuit 10 makes low. Consequently, the output of the AND circuit 9 is low and the output of the output keying signal circuit 8 continues to be OFF. While the detecting circuit 11 of the voltage between the electrode and the nozzle works and the output is high like this, the DC source continues to be OFF.
