摘要： The cross section of a wire is round and is composed of several units, each consisting of tape-like superconductors laminated in an approximately rhombic shape, which are arranged such that they form a hexagon as a whole. Oxide superconducting tape wires each consisting of a plurality of oxide superconducting filaments are arranged in rotational symmetry to a core. The oxide superconducting filaments have the cross section such that the average thickness is 3 to 20 &mgr;m and the average aspect ratio is larger than 2 and smaller than 10. A step of arranging the oxide superconducting tape-like wires in rotational symmetry is accomplished when the multi-core tape-like wires are packed in a third metal pipe which becomes a metal sheath later. Since the multi-core tape wires having oxide superconducting filaments are arranged in rotational symmetry, the oxide superconductor in the oxide superconducting filaments permits its c axis to orient in various directions. This makes it possible to prevent the critical current from decreasing irrespective of the direction in which the magnetic field is applied and to increase the critical current density (Jc) because the oxide superconducting filament has an optimal size. The oxide superconductor should be a bismuth-based oxide superconductor, preferably be the one which has a composition of Bi2Sr2Ca1Cu2Ox.
摘要翻译：线的横截面是圆形的，并且由几个单元组成，每个单元由以大致菱形形式叠层的带状超导体组成，它们整体形成六边形。每个由多个氧化物超导细丝组成的氧化物超导带线布置成与芯部旋转对称。氧化物超导细丝具有平均厚度为3-20μm，平均纵横比大于2且小于10的横截面。当将氧化物超导带状导线布置成旋转对称的步骤是在多芯带状电线被包装在稍后成为金属护套的第三金属管中。由于具有氧化物超导细丝的多芯带线布置成旋转对称，所以氧化物超导细丝中的氧化物超导体允许其c轴在各个方向上取向。这使得可以防止临界电流随着施加磁场的方向而降低，并且由于氧化物超导细丝具有最佳尺寸而增加临界电流密度（Jc）。氧化物超导体应为铋基氧化物超导体，优选为具有Bi 2 Sr 2 Ca 1 Cu 2 x x x的组成的超导体。

摘要： A method for manufacturing an oxide superconducting coil can suppress deterioration of superconducting characteristics caused by a strong electromagnetic force and deformation and a reaction during heat treatment. The oxide superconducting coil is manufactured by a wind-and-react (W&R) method using a metal sheathed oxide superconducting wire material and an insulator, wherein an oxide film formed on a surface of a heat resistant alloy during a heat treatment is used for insulating the coil, and the heat resistant alloy has a sufficient strength to prevent the deformation of the coil generated by the weight of the coil itself during the heat treatment and to endure a strong electromagnetic force. An oxide superconducting coil operable with a coolant, such as liquid nitrogen, liquid helium, and the like, or a refrigerator, can be realized.
