Patents by Inventor William W. Childers

William W. Childers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of localized thermal processing of integrated lead suspensions for controlling the pitch static attitude of sliders
    Patent number: 7152303
    Abstract: A method is provided for controlling the pitch static attitude of a slider in an integrated lead suspension head gimbal assembly. The integrated lead suspension includes a load beam, a mount plate, a hinge and a flexure made out of a multi-layer material. Localized heating is applied to the outrigger leads during the process of forming flexure legs to set a stable pitch static attitude, which does not change, by subsequent thermal exposures.
    Type: Grant
    Filed: August 28, 2003
    Date of Patent: December 26, 2006
    Assignee: Hitachi Global Storage Technologies Netherlands BV
    Inventors: William W. Childers, Tzong-Shii Pan, Surya Pattanaik
  • Method of controlling pitch static attitude of sliders on integrated lead suspensions by improved plastic deformation processing
    Patent number: 6993824
    Abstract: A method is provided for controlling the pitch static attitude of a slider in an integrated lead suspension head gimbal assembly. The integrated lead suspension includes a load beam, a mount plate, a hinge and a flexure made out of a multi-layer material. The flexure legs and the outrigger leads are simultaneously plastically deformed to define the pitch static attitude. The flexure legs and the outrigger leads are deformed at approximately the same longitudinal location.

  • Disk drive with controlled pitch static attitude of sliders on integrated lead suspensions by improved plastic deformation processing
    Patent number: 6992862
    Abstract: The pitch static attitude of a slider in an integrated lead suspension head gimbal assembly of a disk drive is controlled at the manufacturing stage. The integrated lead suspension includes a load beam, a mount plate, a hinge and a flexure made out of a multi-layer material. The flexure legs and the outrigger leads are simultaneously plastically deformed to define the pitch static attitude. The flexure legs and the outrigger leads are deformed at approximately the same longitudinal location.
