  • Surface treatment method for vacuum member
    Patent number: 8517795
    Abstract: A surface-treating process and a forming process in which an inner surface of a vacuum member is mechanically polished in the presence of a liquid medium including no hydrogen atom.
    Type: Grant
    Filed: October 31, 2003
    Date of Patent: August 27, 2013
    Assignee: Nomura Plating Co., Ltd.
    Inventors: Kenji Saito, Tamao Higuchi
  • Copper/niobium composite piping material produced by copper electroforming, process for producing the same and superconducting acceleration cavity produced from the composite piping material
    Patent number: 8470155
    Abstract: In order to produce industrially advantageously an electroformed copper/niobium composite piping material wherein an electroformed copper layer and a niobium thin piping material are strongly bonded to each other, the electroformed copper/niobium composite piping material can be produced by coating any one or each of the outer peripheral surface and the inner peripheral surface of a niobium thin piping material with a nickel thin film, coating the surface of the nickel thin film with copper by electroforming, and subsequently annealing the resultant.
    Type: Grant
