  • Patent number: 8993064
    Abstract: Provided are a substrate for a superconducting compound and a method for manufacturing the substrate which can realize the excellent adhesive strength simultaneously with high orientation of copper. An absorbed material on a surface of a copper foil to which rolling is applied at a draft of 90% or more is removed by applying sputter etching to the surface of the copper foil, sputter etching is applied to a nonmagnetic metal sheet, the copper foil and the metal sheet are bonded to each other by applying a pressure to the copper foil and the metal sheet using reduction rolls, crystals of the copper in the copper foil are oriented by heating a laminated body formed by such bonding, copper is diffused into the metal sheet by heating with a copper diffusion distance of 10 nm or more, and a protective layer is laminated to a surface of the copper foil of the laminated body.

  • Patent number: 8646583
    Abstract: A bellows (2) of a dust boot (1, 30) having large diameter parts (3) and small diameter parts (4) disposed alternately covers a piston rod (R) projecting from a cylinder (C). A bump stopper (B) fixed to the cylinder (C) projects into the bellows (2) as a projecting portion. The bellows (2) comprises a first section (M) which passes a projecting end of the projecting portion according to the elongation and contraction of the piston rod (R) and a second section (L) located therebelow. By making the small diameter parts in the second section (L) have a smaller inner diameter than the small diameter part located at a boundary between the first section (M) and the second section (L), the bellows (2) can be made slim without interfering with the bump stopper (B).
