摘要： PROBLEM TO BE SOLVED: To enable the precise discrimination of the reference position of a crankshaft by differentiating a plurality of spaces of deformable part with the rest of the spaces, generating positive and negative pulses corresponding to the changes in positive and negative directions in the detection signals of a detecting sensor at the deformable part over separate signal lines, and detecting the space between the positive and negative pulses. SOLUTION: When protrusions 13a to 13c where the spaces between deformable parts are shorter and a protrusion 14 corresponding to the reference position of a crankshaft pass in the vicinity of an electromagnetic pickup 1, detection signals which changes in a positive or negative direction are outputted from the electromagnetic pickup 1. A waveform shaping circuit 6 generates positive or negative pulse signals on the basis of the detection signals and separately supplies them for the input ports PA and PB of a microprocessor 3 via a positive pulse signal line or a negative pulse signal line. The reference position of the crankshaft is discriminated in the microprocessor 3, control signals are outputted from an output port PO to control an ignition device 5, etc., via an output interface 4.

摘要： PROBLEM TO BE SOLVED: To make it possible to achieve the low dissipation of a device in the stabilized operating sequence with a simple constitution by providing a standby state setting means, which sets a microprocessor and a memory in the standby-state based on the off information of an ignition switch. SOLUTION: A standby-state setting means 4 supplies a standby signal SM based on the ignition information IG such as the off information supplied from an ignition switch 6 and supplies a standby signal SR to a ROM 3 after the specified time from the output of the standby signal SM. When the ignition switch 6 is turned off, the microprocessor 2 and the ROM 3 are set at the standby mode under the low dissipation current state. Therefore, the dissipation currents of the microprocessor and the ROM are limited to the small values, and the unnessary comsumption of the battery when a vehicle is stopped is prevented. Thus, the low dissipation power can be achieved with the simple constitution.

摘要： PROBLEM TO BE SOLVED: To keep satisfactory sealability against temperature change by arranging a collar member made of material having a linear expansion coefficient smaller than that of synthetic resin around a perpendicular wall of a circular groove made of synthetic resin through integral molding. SOLUTION: When temperature applied to a coil bobbin 1 falls, a perpendicular wall 2A is going to contract inward due to a large linear expansion coefficient of the coil bobbin 1. As for the other end circular flange 1C, a portion between an inner side 1D of the flange 1C and the perpendicular wall 2A is interrupted by a collar member 20. Inward contraction of a portion between the inner side 1D and an inner circumference 20B of the collar member 20 is not influenced at the circular flange 1C. A thin portion 1P corresponding to the circular flange 1C between an outer periphery 20A of the collar member 20 and the perpendicular wall 2A contracts inward, but its rate is very slight.
