    摘要： 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.

    摘要： 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.

    摘要： 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.
