Shaun C. Hogan 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).

  • High-pressure tank and method for fabricating the same
    Patent number: 7137526
    Abstract: A cylindrical reinforcing collar is fitted onto a cylindrical gas discharge section of a tank body and then engaged integrally on the exterior of the tank body between the cylindrical gas discharge section and the dome section by shrink fitting. This provides, easily and inexpensively, a high-pressure tank capable of withstanding high pressures of 35 to 75 MPa while keeping its lightness in weight.
    Type: Grant
    Filed: June 23, 2003
    Date of Patent: November 21, 2006
    Assignees: Samtech Corporation, Samtech International, Inc., Hypercom Engineering, Inc.
    Inventors: Teppei Sakaguchi, Yoshiki Sakaguchi, Shaun C. Hogan
  • High-pressure tank and method for fabricating the same
    Patent number: 6908006
    Abstract: An annular fitting recess is formed circumferentially in the exterior of a tank body in the vicinity of the boundary between a dome section and a cylindrical gas discharge section of the tank body. A cylindrical reinforcing collar is fitted onto the cylindrical gas discharge section of the tank body to fit an annular boss of the reinforcing collar in the fitting recess of the tank body and then engaged integrally on the exterior of the tank body between the cylindrical gas discharge section and the dome section by shrinkage. This provides easily and inexpensively a high-pressure tank capable of withstanding high pressures of 35 to 75 MPa while keeping its lightness in weight.

  • High-pressure tank apparatus
    Patent number: 6675831
    Abstract: To downsize a high-pressure tank apparatus comprising: a high-pressure tank in which high-pressure gas is charged; and a valve mechanism including a regulator valve for reducing the gas pressure in the tank, to prevent damage to the valve mechanism, and to facilitate the handling of the valve mechanism and the like, the valve mechanism is provided at a gas outlet of the high-pressure tank to locate inside of the tank. The valve mechanism includes a capsule fixedly attached to the gas outlet in a gas-tight manner to face the inside of the high-pressure tank. Within the capsule, a shut-off valve for providing and interrupting communication between the inside and outside of the tank by its opening and closing, respectively, and a regulator valve for reducing the pressure of the high-pressure gas in the tank are disposed.
