  • Publication number: 20120207421
    Abstract: An outer ring 6a for a shell-type radial needle bearing having a cylindrical shape with a bottom is achieved for which fatigue life of the bottom plate section 9a and the continuous section between the bottom plate section 9a and the cylindrical section 8a is improved, as well as the anti-corrosion characteristic of the outer ring 6a is improved and the outer ring 6a can be prevented from coming out of the bearing without an increase in cost. After obtaining an intermediate raw material 35 having a cylindrical section and a bottom plate section from a metal raw material, shot peening is performed on the intermediate material 35 to create residual compressive stress in the surface and surface layer section on the outer surface side of the cylindrical section 8a and the bottom plate section 9a such that the residual compressive stress in the surface layer section on the outer surface side is greater than the in the surface layer section on the inner surface side, and from the surface to a depth of 0.

  • Patent number: 7752747
    Abstract: A method of manufacturing an electronic component minimizes the occurrence of voids and degradation of characteristics in a resin-sealed portion, while reducing the costs thereof. A sealing step for sealing surface acoustic wave elements by a sealing resin member formed from a resin film is performed by mounting the surface acoustic wave elements on a collective mounting substrate and the resin film in a bag with a gas-barrier property, and causing the resin film to infiltrate between the surface acoustic wave elements mounted on the reduce-pressured-packed collective mounting substrate to be hermetically sealed by the pressure difference between the inside and the outside of the bag.

  • Publication number: 20090280094
    Abstract: Disclosed is a method for stimulating revascularization in a subject comprising the steps of: (a) administering erythropoietin to the subject; (b) collecting peripheral blood mononuclear cells from the subject; and (c) administering the collected peripheral blood mononuclear cells to a target site of the subject. Peripheral blood mononuclear cells, and particularly CD34-positive cells, are mobilized into the peripheral blood of a subject by the administration of erythropoietin to the subject. The method of the present invention is useful for the treatment of ischemic diseases, such as peripheral vascular disorder.
