摘要:
When an electric appliance unit functions as an electric motor, a rotary shaft is rotated by electric current supplied to the electric appliance unit. When the electric appliance unit functions as a generator, the generator generates electricity as the rotary shaft rotates. A first rotation permitting mechanism is located between the rotor and the rotary shaft to permit the rotor and the rotary shaft to rotate relative to each other. A one-way clutch is located between the rotor and the rotary shaft. The one-way clutch permits the rotary shaft to rotate in one direction relative to the rotor and prevents the rotary shaft from rotating in the other direction relative to the rotor. A second rotation permitting mechanism is located between the housing and the rotor. The second rotation permitting mechanism permits the rotor to rotate relative to the housing. Power transmitted from the external drive source to the rotor is transmitted to the rotary shaft via the one-way clutch. The rotor is supported by the housing with the second rotation permitting mechanism.

A mechanical rotational device includes a housing. An end portion of a rotary shaft protrudes from a front wall of the housing. An electric rotational device is coaxial with the rotary shaft and is coupled to the end portion of the rotary shaft. The electric rotational device functions as at least one of a motor and a generator. A rotational member is coupled to the rotary shaft and has a power transmitting mechanism for transmitting power between the rotational unit and an external device. A one-way clutch is located in the power transmitting path between the rotary shaft and rotational member. The one-way clutch is located inward of the rotational member. The electric rotational device is located on or forward of the housing. At least part of the electric rotational device is located outward of the power transmitting mechanism.

A compressor has a pulley for transmitting torque from an external drive source to a rotary shaft to drive a compression mechanism. The pulley has a pulley body. The compressor has a mass body located in a range that is radially inward of the outer circumference of the pulley. The mass body swings about an axis that is spaced from the rotation axis of the pulley body by a predetermined distance and is substantially parallel to the rotation axis of the pulley body.

An air conditioning system for a vehicle that is driven by a vehicular power source. The system has a compressor selectively operable by the vehicular power source and an electric motor. The electric motor is used as a drive force of the compressor when the vehicular power source is in a non-operative state. The compressor compresses refrigerant gas introduced into a suction chamber from an external refrigerant circuit. A displacement of the compressor is variable, based on a differential pressure. The compressor has a control valve that is disposed on a refrigerant passage communicating with the crank chamber. The control valve has a valve plunger for changing an opening size of the control valve to adjust pressure in the crank chamber. The air conditioning system comprises pressure sensing member, actuator, and controller. The pressure sensing member is disposed in the control valve and applies biasing force to the plunger based on pressure in the external circuit. The biasing force is applied to cancel change of the pressure in the external circuit. The actuator is disposed in the control valve and applies reverse force against the biasing force to the plunger. The plunger is moved to increase the displacement by the reverse force. The controller controls the actuator to increase the reverse force in steps by a magnitude that is small enough that the electric motor is able to stably drive the compressor.

A hybrid compressor system has a hybrid compressor for compressing refrigerant. The compressor is selectively driven by one of a first drive source and a second drive source. The hybrid compressor system also includes a first one-way clutch, a driver for driving the second drive source, a sensor for detecting a rotational state of the first drive source and a controller. The first one-way clutch is arranged on a first power transmission path between the compressor and the first drive source for permitting power transmission from the first drive source to the compressor. The controller is electrically connected to the driver and the sensor. When a drive source of the compressor is switched from the second drive source to the first drive source, the controller orders the driver to stop the second drive source after the rotation of the first drive source is detected.

A power transmission mechanism has a first rotating member rotating around an axis, a second rotating member rotating around the axis and an elastic member located between the first rotating member and the second rotating member. The first rotating member has a first rotating member surface, and the second rotating member has a second rotating member surface. The elastic member has at least a protrusion contacting at least the first rotating member surface. The protrusion extends in a circumferential direction of the first rotating member. The protrusion has gradually tapering shape toward the first rotating member surface. The elastic member is deformed by compression as the elastic member engages the first rotating member surface and the second rotating member surface by rotation of the first rotating member, thereby causing relative rotation of the first rotating member and the second rotating member.

An electronic device includes a power supply and a power supply circuit. The power supply circuit is configured to alternately switch a state of the electronic device between a first state to supply power to another device and a second state to receive power from said another device, and stop a switching operation of the state of the electronic device when the electronic device is off, to fix the state of the electronic device to one of the first state and the second state.

The hydrogen production device of the present invention includes: a first electrode including a conductive substrate and a photocatalytic semiconductor layer; a second electrode that is electrically connected to the first electrode and disposed in a second region opposite to a first region relative to the first electrode; the first region is defined as a region on a side of a surface of the first electrode in which the photocatalytic semiconductor layer is provided; a water-containing electrolyte solution; and a housing containing these. The first electrode is provided with first through-holes and the second electrode is provided with second through-holes; and the first through-holes and second through-holes form a communicating hole for allowing the first region and the second region to communicate with each other. An ion exchange membrane having substantially the same shape as the communicating hole is disposed in the communicating hole to close the communicating hole.
