摘要： PURPOSE:To prevent hunting by modifying the size of a non-sensitive zone on the basis of displacement difference of a temp. regulating element when the displacement difference of the actual displacement amount from the target displacement amount of the temp. regulating element to cause stop of the actuator for temp. regulating element. CONSTITUTION:Inside of an air duct 1 and air mix damper 4 is borne rotatably round a shaft 4a, and in accordance with the degree of opening of this damper, the temp. of the blowout air is adjusted. The air mix damper 4 is driven by a DC motor M of a servo mechanism 9 through a link rod 8. Through a power transistor circuit 18 the DC motor M is controlled by a microcomputer 17 on the basis of information given by different setting device 10 and sensors 11-15. When the displacement difference of the sensed displacement amount from the target displacement amount for air mix damper 4 has come into a non- sensitive zone to cause stop of the DC motor M, the size of the non-sensitive zone is modified on the basis of the displacement difference of the air mix damper 4.

摘要： PURPOSE:To check a drop in revolving speed of an internal combustion engine due to a compressor lock, by dissociating an electromagnetic clutch under the specified high revolution of the engine when a compressor comes into a state of being locked at the initial stage of engine idling. CONSTITUTION:When an ignition switch IG is closed, a fuel injection control system 30 potential divider 81 generates a second reference voltage. And, when analog voltage out of an F-V converter 60a goes higher than the second reference voltage, a comparator 83 emits a comparison signal. At this time, if a compressor comes into a state of being locked, a difference in the analog voltage between F-V converters 60a and 60b goes beyond the specified value. If so, an AND gate 90 emits a gate signal, and an inverter 100 makes a transistor 110 into nonconductibility, whereby a relay 20 opens a switch 22 so that a solenoid coil 10 is demagnetized, thus an electromagnetic clutch is dissociated.
