摘要： PROBLEM TO BE SOLVED: To simplify the structure of a power supply circuit for vehicle which supplies power to a control unit of an on-vehicle apparatus at the time of turning on and off an ignition switch, and reduce the number of parts. SOLUTION: When an ignition switch 8 is ON, a voltage suppressing means 2 is bypassed by a switching transistor 12, and the constant voltage of a constant voltage circuit 1 is supplied to a control unit 4. When the ignition switch 8 is OFF, the bypass of the voltage suppressing means 2 is released, and the constant voltage of the constant voltage circuit 1 is decreased by the voltage suppressing means 2 for supply. It is thus possible to conduct power supply at the time of turning on and off the ignition switch 8, using a single constant voltage circuit.

摘要： PROBLEM TO BE SOLVED: To provide a rotation speed difference sensing type joint capable of prohibiting the relative rotation between a housing and a rotor. SOLUTION: Each spool valve part 60 of an electromagnetic closing valve is provided for the disc part 51 of a rotor. The spool valve part 60 includes a spool hole 61 crossing an outlet path 16, and a valve element 62 provided for the spool hole 61 in such a way as to be freely slid. When an electromagnetic solenoid (not shown in the figure) of an electromagnetic actuator part for the electromagnetic closing valve is energized, the valve element 62 is shifted to a closing position so as to let the outlet path 16 be closed. When the electromagnetic solenoid is de-energized, the valve element 62 is shifted to an opening position so as to let the outlet path 16 be opened.
