  • Apparatus for producing oxide superconductor cable
    Patent number: 5196399
    Abstract: A device for fabricating an oxide superconductor cable includes a spinning furnace for receiving a preform and spinning the preform into a glass fiber. The device further includes a sputtering apparatus for receiving the spun glass fiber and coating the glass fiber with an oxide superconductor film as well as a pulling mechanism for pulling the glass fiber.
    Type: Grant
    Filed: August 6, 1991

    Assignee: Fujikura Ltd.
    Inventors: Takao Shiota, Hiroshi Hidaka, Koichi Takahashi, Masahiro Sato, Osamu Fukuda, Koichi Inada
  • Oxide superconductor cable and method of producing the same
    Patent number: 5093311
    Abstract: An oxide superconductor cable and a method of producing the same. The oxide superconductor cable includes a ceramic fiber and an oxide superconductor layer coated over the ceramic fiber. Such a structure of the cable provides flexibility to it to some extent and enables it to become relatively thin.

  • Single crystal oxide superconductor and method of producing the same
    Patent number: 5057484
    Abstract: A single crystal oxide superconductor and the method of producing the same. One face of a substrate is coated with an oxide superconductor for forming an oxide superconductor layer. Then, the oxide superconductor layer is heated so that the oxide superconductor has a single crystalline structure.
