摘要： A read/write head includes a slider provided with an electromagnetic transducer element (or an optical module), an actuator, and a suspension. The actuator includes a fixed part, a movable part, and at least two beam members for coupling them together. The beam members have a displacement generating means that elongates and contracts by inverse piezoelectric effect or electrostrictive effect. The fixed part is fixed to the suspension, and the movable part is fixed to the slider. Upon the elongation and contraction of the displacement generator, the displacement generator deflects and the movable part displaces linearly, circularly or rotationally with respect to the fixed part, and the electromagnetic transducer element displaces in a linear or circular orbit, so that the electromagnetic transducer element intersects recording tracks. In the actuator, the fixed part, movable part and beam members are formed as an integrated single piece by providing a hole and/or a cutout in a sheet-like member constructed of a piezoelectric or electrostrictive material. The actuator of the structure illustrated is used for the positioning of a direction intersecting recording tracks. In this case, the total sum of voltages applied on the displacement generating means is controlled in such a manner that it is constant at any time, thereby controlling position fluctuations of the electromagnetic transducer element in the direction vertical to the recording medium surface.

摘要： In a non-contact electric power feed system, electric power is supplied in a non-contact manner from an electric power transmission device to a vehicle representing an electric power reception device. The electric power transmission device includes an electric power transmission unit, a communication unit for radio communication with the electric power reception device, and a control device for controlling the electric power transmission unit. The control device varies transmitted electric power from the electric power transmission unit while the electric power transmission unit transmits electric power, and determines whether or not pairing between the vehicle specified as an electric power transmission target and the electric power transmission unit is appropriate, based on information on variation in electric power from the vehicle specified as the electric power transmission target through radio communication.

摘要： A contactless power supply system contactlessly supplies electric power from a power transmitting device to a vehicle. The vehicle includes a power receiving unit contactlessly receiving electric power from the power transmitting device, an electrical storage device storing electric power received by the power receiving unit, and a vehicle ECU. The power transmitting device includes a power supply unit, a power transmitting unit contactlessly supplying electric power, supplied from the power supply unit, to the power receiving unit and a matching transformer used to adjust an impedance between the power supply unit and the power transmitting unit. The vehicle ECU is able to output, to the power transmitting device, a command to adjust the matching transformer, and sets an impedance of the matching transformer on the basis of a power transfer efficiency between the power transmitting unit and the power receiving unit while the electrical storage device is being charged.
