Title: Mold for optical disc base sheet
Inventor: IGARI TOKUO
IPC: B29L17/00
Filed: 1990-06-26
Abstract: PURPOSE:To obtain a mold providing an optical disc base with small internal strain and a few errors for recording and reproducing of information by providing a inclined face in such a way that a part projected in a cavity of an inner peripheral holder ring becomes higher to the outer peripheral side and specifying the height of the projected part. CONSTITUTION:A mold for an optical disc base provides a fixed mirror face 1 and a movable mirror face 2 to form a cavity 3 wherein a molten resin is filled. A inner peripheral holder ring 8 has a projected part in the cavity 3 and when a resin is filled, the resin receives a shearing stress. Magnitude of the shearing stress is determined in accordance with the slope theta to a stamper 12 of the projected part and the height h determined by using the stamper 12 of the inner peripheral holder ring 8 as a standard. The taper angle theta and the height h are 0 deg.<theta<90 deg. and 0mm<h<=1.2mm. When this inner peripheral holder ring is used, the molten resin easily passes between the fixed mirror and the inner peripheral holder ring and shearing stress generated becomes thereby small. In addition, as the optical disc base is easily released from the movable mirror face after molding, no strain is produced in the base during releasing.

Title: Laser working device
Inventor: NISHIDA NAOTO
IPC: B23K26/064
Filed: 1983-09-14
Abstract: PURPOSE:To perform stable laser working by providing a reflecting mirror of which the reflecting surface is inclined with respect to the optical axis and a total reflecting mirror which receives the laser light reflected by said reflecting mirror to a holder of which the center of rotation is made coincident with the optical axis of the laser light and controlling the polarizing direction of the laser light by the rotating angle of the holder. CONSTITUTION:An excitation part 2 is actuated to excite a laser medium thereby oscillating laser light L. Then the laser light L repeats reflection between a total reflecting mirror 8 and a partial reflecting mirror 9 while the direction thereof is changed perpendicularly by a reflecting mirror 7. The laser light amplified in such a way is outputted from the mirror 9. The laser light L is linearly polarized by the mirror 7 in this stage and the direction of the linearly polarized laser light L can be changed by rotating and controlling the mirror 7 in a 0-180 deg. range. The polarizing direction of the light L can be therefore made the same as the driving direction of a work 11. On the other hand if a holder 6 is rotated at a high speed, the laser light is made equivalently to circularly polarized light.
