    • An idling operation control apparatus consists of a closed-loop control system responsive to an average speed of a multi-cylinder internal combustion engine for obtaining a target idling engine speed. In the closed-loop control system, there is provided an individual cylinder control system in which a first data relating to outputs of respective cylinders of the engine is produced in response to an operation timing of the engine and the differential data showing the difference between the output of the respective cylinder and the output of a reference cylinder is calculated on the basis of the first data. A second control data relating to the fuel amount necessary for nullifying the difference indicated by the differential data is also produced in the latter system and the second data is supplied to the closed-loop control system, whereby the difference among the outputs of the cylinder is reduced.

    • A circuit for generating a position signal has a detector having a detecting coil whose inductance varies in accordance with the position of an object which generates a first pulse response signal relating to the inductance of the detecting coil in response to the pulse signal, another detector having a constant inductance coil which generates a second pulse response signal relating to the inductance of the constant inductance coil in response to the pulse signal, and a circuit for producing a digital signal showing the ratio of the inductances of the detecting coil and the constant inductance coil as position data in response to at least the first and the second pulse response signals. The position signal can be directly obtained in digital form and the change in the inductances due to temperature change can be canceled out to obtain position data with high accuracy.
