摘要:
A method of manufacturing a superconductor (12) includes the steps of filling a ceramic superconductor (2) or a material mixture thereof in a metal container (1), elongating the metal container (1), slitting the metal container (1) by a predetermined width to partially expose a material (2) inside the metal container (1), and sintering the material (2) inside the metal container (1).
摘要:
Disclosed are a low-temperature burnt conductive paste which is prepared in such a manner that a base material consisting of 50 to 95% by weight of a powder of at least one conductive material selected from the group consisting of copper, a copper alloy containing copper as a major component, and oxides thereof and 5 to 50% by weight of a glass powder having a softening point of 300 to 600°C and a coefficient of thermal expansion of 6 to 13 × 10⁻⁶°C⁻¹ is dispersed in an organic vehicle, and a method of manufacturing a printed circuit board using the paste.
摘要:
A flaky oxide superconductor essentially consists of a rare earth element or Bi, an alkaline earth metal, copper, and oxygen, and has a flaky outer appearance, a laminar crystal structure, and a direction of thickness (t) coinciding with the c-axis of the crystal. A method of manufacturing the flaky oxide superconductor is also disclosed.

摘要:
A joined parts of Ni-Ti alloys with different metals having a joined interfacial parts of Ni-Ti alloys with different metals other than said alloy, comprising a melt forged structure obtained through the reactive fusion due to the fusion of at least one metal bordering on said joined interface and the application of pressure, and a hot forged structure of Ni-Ti alloys obtained by softening said alloy at high temperature and applying pressure on the side of Ni-Ti alloys and a hot forged structure of said different metals obtained by softening said metal at high temperature and applying pressure on the side of different metals across said melt forged structure, and a direct joining method for obtaining this joined parts are disclosed. It is possible to join Ni-Ti alloys component with different metals component providing high strength without deteriorating the characteristics.
