Abstract

PURPOSE: To remove the adverse effect of noise upon detection of two magnetic pickup phase displacements for a rotating angle detector for controlling the ignition timing synchronously with the cranking operation of an internal combustion engine and readily form the standard projection of a rotary disk plate for the detector.
CONSTITUTION: First and second pickup coils 1b, 2b are faced oppositely with a rotary disk plate 4 at predetermined angle θ1, and third pickup coil 3b is installed between the pickups. The plate 4 incorporates an angle signal projcetion 4a at an angle θ2 and a standard signal projection 4b at predetermined angle thereon. Third stator 3a opposes only the projection 4b stepwide from the other projection. This circuit consists of an angle signal circuit A and a standard signal generator B. A comparator COM3 integrates in the circuit B to form zero potential forcibly at no signal time. The projections 4a, 4b are point welded onto the plate 4 with silver solder.
