  • Patent number: 8920887
    Abstract: A method of bonding a conductive material to stainless steel includes: a first step of applying a conductive paste to a surface of a base plate made of the stainless steel; and a second step of removing, in an area located within the surface of the base plate and covered with the conductive paste, a part of a passivation film on a surface of the stainless steel without allowing a base material of the stainless steel of the base plate to come into contact with air. The removing of the passivation film is achieved, for example, by irradiation of laser light.

  • Patent number: 8369047
    Abstract: A flexure metal plate includes distal and proximal end side-center-support plate forming regions that are positioned on distal and proximal sides within an open section. To a distal end section of a supporting part that is positioned on a distal side of the open section, first and second-distal side-metal plates are fixed so as to be positioned on an outer side of the distal end side-center-support plate forming region in a width direction, and to a proximal end section of the supporting part that is positioned on a proximal side of the open section, first and second-proximal side-metal plates are fixed so as to be positioned on an outer side of the proximal end side-center-support plate forming region in the width direction. The first and second-distal side-metal plates form a distal end side-support plate in cooperation with the distal end side-center-support plate forming region.

  • Patent number: 8248735
    Abstract: In a magnetic head suspension, a piezoelectric element is disposed within a supporting part's open section so that at least a part of its distal-side end surface faces a distal-side wall surface of the supporting part's distal end section forming a distal-side gap between the distal-side end surface and the distal-side wall surface and at least a part of its proximal-side end surface faces a proximal-side wall surface of the supporting part's proximal end section forming a proximal-side gap between the proximal-side end surface and the proximal-side wall surface in a state where the piezoelectric element's upper and lower electrode layers do not face the supporting part and any rigid members that are fixed to the supporting part. The piezoelectric element is fixed to the supporting part by a distal-side insulative adhesive agent and a proximal-side insulative adhesive agent.
