Abstract: When a control unit starts to supply power to an electromagnetic coil in a first direction, a magnetic force generated by a non-attracting magnetic circuit becomes larger than a magnetic attraction force generated by an attracting magnetic circuit. As a result, a movable member is guided by a guide portion of a yoke and moves to a second position from a first position. When the control unit starts to supply power to an electromagnetic coil in a second direction, the magnetic attraction force generated by the attracting magnetic circuit becomes larger than the magnetic force generated by the non-attracting magnetic circuit. As a result, the movable member is guided by the guide portion and moves to the first position from the second position. Accordingly, the movable member can reliably perform a moving operation when turning ON/OFF.

Abstract: A ring insertion groove is formed between adjacent two of circular plates, which are made of a magnetic material and are arranged concentric with each other, and a ring, which is made of a non-magnetic material and has a larger deformation resistance in comparison to the magnetic material of the plates, is press fitted into the ring insertion groove. Thereafter, a peripheral part around an opening of the ring insertion groove is plastically flowed, so that a compression stress is left in the ring.

Abstract: An electromagnetic clutch is provided with: a rotor which has a friction plate; a stator which has an electromagnetic coil; and an armature which is attracted to the friction plate by electromagnetic attraction force generated by the conduction of electricity to the electromagnetic coil. The electromagnetic coil includes electromagnetic coils. The electromagnetic clutch is also provided with a circuit switching section which is configured in such a manner that, when a switch-on command is outputted, the circuit switching section allows an electric current to flow in parallel into the electromagnetic coils, and then, after the armature is attracted to the friction plate, the circuit switching section switches a circuit for conducting electricity to the electromagnetic coil, from a parallel circuit to a series circuit so that an electric current flows in series into the electromagnetic coils.

Abstract: An energy conversion device includes a first acoustic wave generator, a second acoustic wave generator, and an output unit which are provided in a pipe member. The first acoustic wave generator has a thermal energy generator configured to generate thermal energy from electric energy, and converts the thermal energy generated by the thermal energy generator into acoustic energy to generate acoustic wave in working gas by a self-excited thermo acoustic vibration. The second acoustic wave generator converts thermal energy supplied from a heat supply source into acoustic energy and generates acoustic wave in working gas by a self-excited thermo acoustic vibration. The output unit converts the acoustic energy of the acoustic waves from the first acoustic wave generator and the second acoustic wave generator into cold energy to output.

Abstract: When a clutch relay connects between a control device and a vehicle electric power source in response to outputting of a clutch OFF signal from an electronic control device to the clutch relay, a timer circuit starts a control operation for energizing coil portions. When a predetermined time period elapses, the timer circuit terminates energization of the coil portions. When the clutch relay connects between the control device and the vehicle electric power source in response to outputting of a clutch ON signal from the electronic control device to the relay, the timer circuit starts a control operation for energizing the coil portions. When a predetermined time period elapses, the timer circuit terminates energization of the coil portions.
