A pickup device has a core to which a coil is wound about. The core has a body formed by laminating a plurality of plates having a predetermined shape. Eddy currents produced by leakage flux is suppressed at the ends of the core. This is achieved by laminating a plate, which has a certain shape and is made of a material having a higher electric resistance value than the body, to the ends of the body. The generation of eddy currents may also be suppressed by providing notches at the ends of the core to obstruct the formation of a magnetic circuit at the ends. As another option, space may be provided at the ends of the core to disconnect the path of eddy currents.

A transmission device includes a casing elongated towards a power transfer aperture, a power output member rotatably supported in the aperture by a first bearing, and a power transfer shaft with an outer end rotationally coupled to the power output member and an inner part supported from the casing by a second bearing. The shaft has an axial aperture for receiving lubricating oil and a radial aperture communicating thereto for squirting out lubricating oil radially as the shaft revolves. An oil shield cover has a base mounted to the casing, an extension elongated under the shaft from the base towards the first bearing, an end wall reaching upwards from the end of the extension towards the shaft with the lowest point of its upper edge closely approached thereto at an axial position on the shaft at which its diameter is substantially less than where it is supported by the second bearing. The extension rises on either side of the shaft at least to the height of the lowest point of the upper edge of the end wall, and has an opening on its upper part corresponding to the radial aperture. A space for pooling lubricating oil ejected from the radial aperture is defined by the oil shield cover and the casing, and as lubricating oil accumulates therein it first can escape by overflowing over the end wall of the oil shield cover. The lubricating oil pool at this stage reaches high enough to wet the lower portion of the first bearing.

A non-contact power supply system supplies electric power in a non-contact manner from a power transmission device to a vehicle. The power transmission device includes an impedance adjusting unit configured to adjust an impedance between a power supply unit and a power transmission unit. A vehicle ECU assists an alignment between the power transmission unit and the power receiving unit in the parking operation based on a power transmission efficiency between the power transmission unit and the power receiving unit. A power transmission ECU, at the time of the alignment in the parking operation, controls the impedance adjusting unit based on a distance between the power transmission unit and the power receiving unit in a vertical direction (vehicle height). Accordingly, lowering of the power transmission efficiency caused by a change in an impedance along with a change in the vehicle height can be suppressed.

An information recording/reproducing apparatus is capable of recording the video information on an optical disk and reproducing the video information which has been recorded on the optical disk in accordance with a play list. The apparatus includes the detecting unit which detects an unnecessary portion of the video information not to be reproduced by any play list, and the erasing unit which erases the video information with respect to the detected unnecessary segment, which has been recorded on the optical disk.

A primary regulator valve has a cutback port which regulates a line pressure to increase, at the first speed of D range, a throttle pressure is applied to the cutback port through a cutback valve. The primary regulator valve sets the line pressure from a line pressure port higher. The cutback valve has a spool which is compressed in one direction. A first control chamber which is connected to a hydraulic servo (for example, a second brake hydraulic servo) which hydraulic pressure is applied at more than the second speed is formed against the pressing direction, a second control chamber which is connected to a hydraulic servo (for example, a second-coast brake hydraulic servo) to limit a coasting condition of the second speed is so formed as to follow the above pressing direction. At the second speed of second range, the cutback valve, as the first speed of D range, the throttle pressure is applied to the cutback port. Furthermore, the primary regulator valve has a control chamber which regulates the line pressure to decrease. A pressure control valve (for example, a linear solenoid valve to control a lock-up clutch) is connected to the control chamber to reduce the line pressure when a manual valve is selected from N range to D or R range.

A superconductor is produced by electric discharge explosion flame spraying of a composite body of constituents of an immiscible alloy. The electrically discharged composite body is deposited on a substrate and the resultant alloy is oxidized to yield an oxide of the alloy having superconductive property. This process can be applied to the Ln-Ba-Cu system (Ln is at least one of the rare earth elements including Y), typically the Y.sub.1 Ba.sub.2 Cu.sub.3 - or Y.sub.2 Ba.sub.4 Cu.sub.8 system, or other immiscible alloy systems such as the Bi-(Ca, Sr)-Cu system to form an oxide thereof.

A contactless power supply system contactlessly transmits electric power from a power transmitting device to a vehicle. The vehicle includes: a power receiving unit that contactlessly receives electric power from the power transmitting device; an electrical storage device that stores electric power received by the power receiving unit; and an impedance adjustment unit that includes a DC/DC converter and a relay and that is used to adjust an impedance between the power receiving unit and the electrical storage device. A vehicle ECU switches between a power supply path of which the impedance is adjusted by the DC/DC converter and a power supply path that does not use the DC/DC converter on the basis of a state of charge of the electrical storage device.

A non-contact power transmission apparatus includes a high-frequency converting section, which converts input voltage to high-frequency voltage and outputs it, a primary coil, which receives high-frequency voltage from the high-frequency converting section, and a secondary coil, which receives electric power from the primary coil. The non-contact power transmission apparatus further includes a load to which the electric power received by the secondary coil is supplied, a rectifier located between the secondary coil and the load, and an output adjusting section, which supplies, as pulses, output voltage to the high-frequency converting section. The output adjusting section is configured to increase or reduce output to the load by adjusting a duty cycle of the pulse output.

Capabilities of suppressing erosion caused by liquid droplets and achieving a short operation period and cost reduction are provided. A build-up welding method for a structural material used in an erosive environment includes: removing a portion exposed to the erosive environment from the structural material; and forming a hard layer in a portion of the structural material, from which the portion exposed to the erosive environment is removed, the hard layer being formed by short circuiting transfer gas metal arc welding using a solid wire with a hardness of HV 400 or more.
