    摘要: A glass material (4) is placed in a forming die including a pair of upper and lower dies (1, 2) and a control member (3) for controlling the space between the upper and the lower die, and then heated, softened, and molded by pressure into a glass substrate in the shape of a parallel plate. The amount of thermal contraction of the control member is smaller than that of the glass material. Therefore, the glass substrate is released from the die when cooled after molding. The present invention can provide a glass substrate that is excellent in smoothness and form accuracy of the surface, and that is suitable for recording media such as magnetic disks that are inexpensive and suitable for mass production.

    摘要: A method for forming a plurality of optical elements simultaneously includes placing a transfer material against an inner surface of a master die, which has a shape commensurate with a desired shape of a plurality of optical elements to form a molding die, which thereby has an inner surface substantially a negative of the master die's inner surface. A moldable sheet, such as glass, is pressed against the molding die to form a unitary molded sheet, and the molded sheet is cut apart to form a plurality of optical elements, including lenses or other optical elements as desired.

    摘要: A transfer arm holds a plurality of preforms arranged in a single line and simultaneously drops and supplies the preforms downward. A positioning arm has a pair of arm split members split in its widthwise direction. The arm split members have positioning surfaces formed on their contact surfaces to be brought into contact with outer peripheries of the preforms. After the preforms are dropped and supplied from the transfer arm, the arm split members of the positioning arm are opened and closed so that the positioning surfaces are brought into contact with the outer peripheries of the preforms. Thus, the performs are properly positioned.

    摘要: The forming apparatus has top and bottom die assemblies which form a heated silica glass material by press forming. These top and bottom die assemblies include, respectively, mold dies, which are made of isotropic carbon, and core molds, which are made of vitrified carbon. The heating and pressing time of a silica glass element, which requires a high forming temperature, is shortened by pinching the silica glass material between top and bottom core molds by controlling a torque so as to produce a close contact condition which permits heat transfer from the top and bottom core molds to the silica glass material between the top and bottom core molds.
