  • Patent number: 10886041
    Abstract: In a high-temperature superconducting conductor 10, a laminated body 15 is formed by laminating a high-temperature superconducting layer 14 on one side surface of a flexible and tape-shaped metal substrate 12 via an intermediate layer 13, and a plurality of thin film wires 11 are formed by providing a stabilization layer 17 around the laminated body 15 via a protective layer 16 and are arranged in a thickness direction. The plurality of thin film wires 11 are connected at both ends in a width direction to each other in a conductible state in a longitudinal direction by means of conductive coupling member 20, in such a manner that a thin film wire 11 disposed at an outermost side is positioned with a surface 18 on a side of the metal substrate 12 directed outward and a surface 19 of each of the plurality of thin film wires 11 facing the high-temperature superconducting layer 14 is held in a non-fixed state with respect to an opposing surface.

  • Patent number: 9691532
    Abstract: A connection structure of a multi-layer wire includes at least a substrate, a high-temperature superconducting layer, a tape-type laminated body, a conductor layer, and a passage forming body. The high-temperature superconducting layer is formed on one surface of the substrate. The tape-type laminated body including at least the substrate and the high-temperature superconducting layer. The conductor layer covering an outer periphery of the tape-type laminated body. The passage forming body serving as a flowing path of a superconducting current generated in the high-temperature superconducting wire piece. The passage forming body is bonded by a bonding material is arranged on a side surface of the conductor layer, the side surface being located on an opposite side to the high-temperature superconducting layer with respect to the substrate.
