Title: Hologram
Inventor: ONAYAMA SHIYUUICHI
IPC: G11B7/135
Filed: 1987-09-28
Abstract: PURPOSE:To simplify an optical system and adjusting operation by providing a hologram face comprising two areas to focus the diffracted light to two different points, respectively to one face, and a diffraction grating face dividing the light beam into three light beams to the other face. CONSTITUTION:A laser beam from a laser light source 1 is divided into three light beams on the diffraction grating face 10B in transmitting through the hologram 10. Then the returned light reflected on a disk signal face via an objective lens 5 is diffracted by a prescribed angle on the hologram face 10A in transmitting through the hologram 10 again and its diffracted light is detected by 6-division photodetector 11. Thus, the detection of a focusing error, a tracking error and a reproducing signal is attained. Thus, the optical system is simplified so as to simplify the adjusting operation and to attain small size and light weight.

Title: Electric discharge machining method
Inventor: KISHI HAJIME
IPC: B23H9/06
Filed: 1983-12-23
Abstract: PURPOSE:To make it easy to produce figures or patterns on the surface of a work through electric discharge machining by placing, between an electrode and a work, a shield made of an insulating material corresponding to a non-machining section in the profiling electric discharge machining method and by applying a voltage between the electrode and the work. CONSTITUTION:When an electrode 4, on which an insulated coating 10 of a specific shape or pattern is formed, is positioned to oppose a work 2 set in a processing bath 1, it means that a shield consisting of an insulating material corresponding to the pattern of a non-machining section is placed between the electrode 4 and the work 2. When a voltage is applied between the electrode 4 and the work 2 by an electric discharge machining unit, a spark discharge occurs between them; however, since there is no spark discharge from the insulated coating portion of the electrode 4, the work 2 is discharge-machined, leaving the portion corresponding to the insulated coating 10 unmachined. In this way, the electric discharge machining is performed to the prescribed depth, and the prescribed patterns or figures can be machined on the surface of the work 2.

Abstract: PURPOSE:To eliminate curling by a method wherein a base material composed of an aromatic polyamide fiber is impregnated with a resin composition capable of being cured without forming a volatile byproduct and a metal foil is laminated to the single surface of the impregnated base material and, subsequently, the laminated base material is cured under heating to obtain a sheet which is, in turn, wound around a metal drum so that the surface of the metal foil becomes outside to be subjected to post- curing. CONSTITUTION:The long base material unwound from a reel 1 passes through a dryer 2 to be dried. The base material after drying is continuously and quantitatively impregnated with a radical curable resin solution by a coater 3. Next, the metal foil and air shielding material delivered from reels 4, 5 are laminated to the impregnated base material by a laminating roll 6 while thickness is controlled and the uncured laminate 10 is guided to a heating furnace 7. Next, the cured laminate 11 is continuously taken up by a taking-up machine 8 to be taken up by a product winder 9. The air shielding material is peeled off from the product by the machine 8 to be taken up by a winder 12. The laminated sheet thus cured is wound around the metal drum of a separate line and the start and end parts thereof are fixed to the drum to subject the wound one to after-curing. By this method, the curling of the laminated sheet can be reduced.
