Toshihiro Takeshima 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).

  • Vibration damping support apparatus
    Patent number: 8500109
    Abstract: A first load transmission surface 54 and a second load transmission surface 56 are each formed as a flat surface extending parallel to a load input direction. Therefore, elastic deformation occurring in each of an outer body part 66 and an inner body part 68 in a stopper elastic body 64 includes a main component of a shear deformation component, and a secondary component of a compressive and tensile deformation component that is small relative to the shear deformation component. Consequently, a sharp increase in deformation resistance and dynamic spring constant when a high load is input can be effectively suppressed.

    Filed: April 10, 2007
    Date of Patent: August 6, 2013
    Assignees: Bridgestone Corporation, Nissan Motor Co., Ltd.
