Title: Information apparatus of recording medium
Inventor: TAGUCHI YOSHIKADO
IPC: G11B17/04
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To precisely stop a holder to the reproducing position. SOLUTION: A cam gear 30 transfers a rotating force of a motor 20 to a rack to the reproducing position from the waiting position. When the rack moves to the reproducing position from the waiting position, a play sensor 82 as a photodetection sensor detects the linear part 31C of the cam gear 30 to turn on. Namely, when a play sensor 82 detects the reproducing position, a motor 20 immediately stops depending on the ON signal of the play sensor 82. Therefore, since the holder (rack 14) is immediately stopped depending on the play sensor 82 which results in less amount of fluctuation in comparison with a mechanical switch, the holder may be accurately stopped at the reproducing position.

IPC: H05K3/34
Filed: 1992-07-01
Abstract: PURPOSE:To prevent a pattern hole from clogging and deformation of a solder after transferring by a method wherein an extrusion member is extruded in a screen mask and a cream solder filled up in a pattern hole is extruded on an electrode on a substrate to transfer it thereon. CONSTITUTION:After a screen mask 2 is disposed on an under receiving member 30, a squeegee 17 is slid to fill up a pattern hole 3 with a cream solder 4. After the squeegee 17 is turned out right under a squeegee turnout section, an elevating plate 23 is fallen down by a motor so that a pressing member 29 presses the mask 2, thereby a part of the pressing member 29 is pressed into an inner section of the pattern hole 3 by the elastic deformation of itself to stiffen the solder 4 therein. Consequently, the elevating plate 23 is raised up, then the mask 2 is transported from a filling device to a base 40 of a transferring device by a conveyor. The falling down of an extrusion member by a motor causes the mask 2 to be extruded by a protrusion 44 for extruding so that the solder 4 is transferred on an electrode 7 on a substrate S.

Abstract: PROBLEM TO BE SOLVED: To lower self-discharge to be generated in the case where a carbon electrode is used for negative electrode by charging a lithium secondary battery once or more at a temperature higher than the operating temperature. SOLUTION: A self-discharge is generated in the case where charge is insufficient and a vacant part, to which lithium is to be moved, exists in the carbon and the movement of lithium to the vacant part is speeded up with a temperature change and the number of vacant part, to which lithium is to be moved, is increased. At this stage, all vacant parts, to which lithium is to be moved, are filled with lithium at the operating temperature by charging a lithium secondary battery at a temperature higher than the operating temperature. Furthermore, charging speed in the electrolyte is increased, and a quantity of charge at a constant current value is increased. A similar condition is generated in the case where other alkali metal is inserted into the carbon, and this method is utilized for a battery utilizing insertion and drawing of the alkali metal into/from the carbon.
