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： In a metal sheath MgB2 superconducting wire, it is intended to achieve a wire having increased current density and a long length at the same time, by densitying superconducting core part. The superconducting wire is manufactured by forming diffusion hardened layer on the inner surface of the sheath such that the hardness of the inner surface becomes higher than that of the outer surface, filling MgB2 superconductor, and further if necessary, a critical current density increasing material such as indium, copper, and tin, in a metal sheath, to subject it to wire drawing. For the metal sheath, a material with toughness such as steel is used. Even if the sheath is made to a long wire, it does not break, thereby, enabling to density superconducting core part.
