摘要:
A method of manufacturing a superconductor includes the steps of filling a ceramic superconductor or a material mixture thereof in a metal container, elongating the metal container, slitting the metal container by a predetermined width to partially expose a material inside the metal container, and sintering the material inside the metal container.

A multifilamentary oxide superconducting wire includes a metal matrix and a plurality of flat oxide superconductor filaments arranged in the metal matrix such that wide directions thereof are radially arranged in a section of the metal matrix. A method of manufacturing a multifilamentary oxide superconducting wire includes the steps of filling a raw material of an oxide superconductor in a through hole of a metal member to form a composite billet, subjecting the composite billet to a diameter reduction process to form a composite wire having a fan-like section, arranging composite wires so that larger arcs of the composite wires are located on the outer side, thus forming form a composite wire arrangement, covering the composite wire arrangement with a metal member to form a metal-covered composite wire arrangement, and performing a predetermined heating process of the metal-covered composite wire arrangement, thus forming the raw material into an oxide superconductor.

Disclosed herein is a ceramic superconductor comprising a ceramic superconductive member, and a high-conductivity metal layer covering the ceramic superconductive member. At least one portion of the metal layer having low electrical conductivity or low thermal conductivity. Also disclosed is a method of manufacturing a ceramic superconductor, comprising the steps of filling a ceramic superconductor or a precursor thereof in a high-conductivity metal pipe, thereby forming a composite member, rolling the composite member into a ceramic superconductor element of a desired shape, which comprises a ceramic superconductive member and a high-conductivity metal layer covering the ceramic superconductive member, performing a predetermined heat treatment on the ceramic superconductor element, and alloying a predetermined portion of the high-conductivity metal layer, thereby rendering the portion less conductive either electrically or thermally.

摘要:
A film deposition apparatus includes a turntable provided in the chamber and having on a first surface a substrate receiving area in which a substrate is placed; first and second reaction gas supplying portions supplying first and second reaction gases to the first surface, respectively; a separation gas supplying portion provided between the first reaction gas supplying portion and the second reaction gas supplying portion and supplying a separation gas that separates the first reaction gas and the second reaction gas; an evacuation port that evacuates the chamber; a space defining member provided for at least one of the first and second reaction gas supplying portions and defining a first space between the at least one of the first and second reaction gas supplying portions and the turntable and a second space so that the separation gas is likely to flow through the second space rather than the first space.
摘要:
An electric motorcycle in which a power drive unit and a motive power generation motor for traveling are secured to a swing arm swinging around a pivot shaft, and power from a battery is supplied through the power drive unit to the motive power generation motor. A hollow inside of the swing arm is partitioned into an air introducing space and an equipment fixing space by a partition wall. The power drive unit is secured in the equipment fixing space so as to be in close contact with the partition wall and a fin extending from the partition wall to the air introducing space are formed at a fixing surface of the air introducing space to which the power drive unit is attached.

An apparatus is configured to include a gas supplying part configured to supply a plasma generating gas on a surface on a substrate mounting area side in a turntable and an antenna configured to convert the plasma generating gas to plasma by induction coupling and provided facing the surface of the substrate mounting area side in the turntable so as to extend from a center part to an outer edge part of the turntable. The antenna is arranged so as to have a distance from the turntable in the substrate mounting area not less than 3 mm longer on the center part side than on the outer edge part side.
摘要:
A layout for an exhaust pipe which also serves as a drainage pipe which prevents splashing of water generated in a fuel cell toward a passenger or splashing toward a tire. Humid excessive gas supplied from a fuel cell is diluted in a dilution box by off-gas discharged from the fuel cell and is used for humidifying air in the humidifier. An exhaust pipe is connected to the dilution box, and diluted hydrogen gas is discharged via the exhaust pipe. Vapor mixed in hydrogen gas is condensed in the exhaust pipe and turned into water, which is drained through the exhaust pipe that extends rearwardly of a vehicle body through the interior of a power unit. A discharge port of the exhaust pipe (which is also a drainage port for water generated in the fuel cell) is positioned at the widthwise center of the vehicle body.
