Title: Electro-chemical conbined machining method for both surfaces of thin plate material
Inventor: TAMIYA KATSUTSUNE
IPC: B23H5/06
Filed: 1985-05-24
Abstract: PURPOSE:To enable the method to perform high efficient and high accurate combined polishing, by forming surface plate tools in both sides from an electric insulating material while applying AC voltage or pulse voltage across conductive materials, embedded in a part of each polishing surface, so as to alternately generate electro-chemical action in both surfaces of a thin plate material. CONSTITUTION:The polishing method, while supplying machining fluid 14 and abrasive polishing grains 15 to a part between both surface plate tools 9, 10, mutually oppositely rotates the tools to be relatively moved while applies pressing force so as to press the tools approaching to each other, and if AC voltage or pulse voltage is applies between conductive materials 11, 12 through conductive rings 21, 22 and brushes 23, 24, electro-chemical combined polishing is performed on both surfaces of a thin plate material 13 by polishing action through the polishing abrasive grains 15 and electro-chemical action. Here the method, rotating each carrier 25 on its own axis and around the center of the surface plate tool and performing a planetary motion of the thin plate material 13 electrically supported to these carriers, provides streak marks by the both surface polishing abrasive grains 15 in no-directivity to obtain a polished surface of uniform quality. While the method, if it adhesively attaches in its finishing process to polishing surfaces 9, 10' of the tools 9, 10 a polishing cloth having insulation, viscous elasticity and water content properties, can more effectively finish mirror surface polishing.

Filed: 1983-06-24
Abstract: PURPOSE:To obtain an address signal always having a correct value by correct ing the value of the address signal on the basis of the value of an address signal obtained before one rotation of a recording medium when the value of the address signal breaks the regularity corresponding to the reproducing speed. CONSTITUTION:A reproducing device 10 reproduces a disc-like information recording medium (disc) in which address signals indicating the positions of a recording program are recorded every rotation by plural times at a fixed reproducing speed.
