    摘要: An oxide superconducting layer is formed on a base material of silver, whose single side is coated with MgO, or single-crystalline MgO for depositing a Bi.sub.2 Sr.sub.2 Ca.sub.2 Cu.sub.3 phase in a crystallographically oriented state by sputtering, CVD or laser ablation. Metal lead or lead oxide is then laid thereon by sputtering to obtain a two-layer structure, and the two-layer structure is heat treated in the atmospheric air. Thus, a bismuth oxide superconducting film, which is excellent in crystal orientation as well as denseness and thereby having high critical current density, is formed on the base material.

    摘要: An oxide superconductive wire is provided by, for example, forming an oxide superconductive layer on a tape-type flexible base. A preliminary compressive strain is applied to the oxide superconductive layer in the longitudinal direction. The remaining strain can be provided by using a base having thermal expansion coefficient larger than that of the oxide superconductive layer and by cooling the same after heat treatment, due to contraction of the base. Since the preliminary compressive strain is applied to the oxide superconductive layer, degradation of superconductivity of the oxide superconductive layer can be suppressed even if the oxide superconductive wire is bent in any direction, compared with the wire without such strain. Therefore, the oxide superconductive wire can be coiled, for example, without much degrading the superconductivity.

    摘要: A sheet feeding and separating device incorporated in image forming equipment for feeding sheets one by one from a sheet stack while preventing two or more sheets from being fed together as far as possible and, when a plurality of sheets are accidentally fed together, surely separating one of them from the others. A pick-up member is implemented as an endless dielectric belt. An AC power source forms a charge pattern on the belt via an electrode. As a result, the belt retains a sheet by attraction and transports it due to the Maxwell stress generated in the sheet. When a plurality of sheets are fed together, an arresting member which faces the belt separates one of them from the others. Alternatively, a charge pattern may be formed on the surface of the arresting member.
