Title: Optical pickup
Inventor: YOSHIKANE TETSUO
IPC: G11B7/09
Filed: 1988-12-19
Abstract: PURPOSE:To obtain an information reproducing signal which is always stable even if a change occurs in a height relation between a pickup stand and a disk reproducing surface by making the fixed end of a cantilever elastic supporting body which is provided with a focus lens in a free end movable with respect to the pickup stand. CONSTITUTION:When the change occurs in the height relation between the pickup pedestal and a disk in the reproduction state of a bowl-shaped solid disk, a focus offset voltage occurs at first. When the voltage is detected and a prescribed voltage is impressed on a hight servo coil 23, a suspension holder 10 slides to a method removing the focus offset voltage along a slide pin 19. Thus, the offset voltage can be held to minimum and the information signal can stably be reproduced by moving the fixed end of the piece holding elastic supporting body which is provided with the focus lens 6 in the free end.

Title: Current collector sheet for battery and electrode using this current collector sheet
Inventor: IECHI HIROYUKI
IPC: H01M10/05
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To minimize the deterioration of charge and discharge capacity or the deterioration of load characteristic in the use of repeated charge and discharge by using a metal foil the surface of which is mechanically polished in such a manner that the surface temperature never exceeds 45 deg.C. SOLUTION: Prior to the application of an electrode active material mixture to a current collector sheet formed of a metal foil, the blasting for spraying powder particle to the current collector surface to mechanically polish it is performed in such a manner that the current collector surface never exceeds 45 deg.C, preferably 40 deg.C. In order to prevent the surface temperature of the metal foil from exceeding 45 deg.C, a feedback method by temperature sensor is employed. Since the adhesion is improved by penetrating the electrode active material mixture into the dimple structure formed on the metal foil surface by the blasting to enhance the adhesion between current collector and electrode active material, the electrode active material can be made hardly peeled from the sheet surface. Thus, the life of the battery can be extended.
