  • Patent number: 10456994
    Abstract: A composite container is provided where FRP layers are formed by winding FRP around a metal liner so that the dome sections are reinforced while limiting an increase in the weight. The FRP layers include a hoop layer that covers the entirety of the cylindrical section in hoop winding, and dome section reinforcing layers that also cover as least the portions of the cylindrical section near the dome sections. In the dome section reinforcing layers, FRP are wound in helical form in such a manner that the orientation angle of the FRP over the cylindrical section relative to the direction of the axis of the liner continuously changes towards the center of the cylindrical section, and thus, the weight of FRP near the center of the cylindrical section is reduced.

  • 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.

  • Patent number: 6886711
    Abstract: In a high-pressure tank 1 in which a gas discharge section 5 is extended from one end of a cylindrical section 2 through a dome section 4 by plastically deforming a short hollow cylindrical blank of metal, the gas discharge section 5 is set at a thickness at least three times that of the cylindrical section 2, and the dome section 4 is gradually increased in thickness from that of the cylindrical section 2 to that of the gas discharge section 5 in proceeding from the cylindrical section 2 to the gas discharge section 5. Thereby, a high-pressure tank capable of withstanding higher pressures than used at the present time is provided easily and at low cost.

  • Patent number: 6729170
    Abstract: A fuser roller is obtained by heating a blank over predetermined regions starting from both the opening ends, and then necking the heated regions of the blank by moving a forming roller with rotation on the heated regions through the external pressing of the forming roller against the heated regions of the blank being rotated on its axis to draw form sidewalls integrally at both ends of a cylindrical body of the blank, respectively, and draw form cylindrical shafts integrally with the sidewalls, respectively. In this manner, the fuser roller can be fabricated using a single processing machine with respect to a single pipe member, which reduces equipment cost, further enhances production efficiency and implements low-cost production of fuser rollers.

  • 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.

  • Patent number: 6279366
    Abstract: Using a form roller in which a plurality of gear-like tooth generating sections are arranged along the rotation axis of the form roller in the outer periphery thereof to increase tooth heights of the tooth generating sections in a stepwise manner along the rotation axis, a plurality of teeth are generated stepwise in the outer periphery of a metallic material by pressing the plurality of gear-like tooth generating sections of the form roller in increasing order of tooth height against the outer periphery of the rotating metallic material while transmitting the rotation force of the metallic material to the form roller to roll the form roller along the outer periphery of the metallic material, and are finished to size by cold pressing. In this manner, external teeth can be generated in the outer periphery of the metallic material with high efficiency and accuracy and without decreasing strength.
