Title: Positioning device of objective lens for optical disk
Inventor: MORIMOTO TAKAO
IPC: G11B7/09
Filed: 1983-12-13
Abstract: PURPOSE:To set easily and with high accuracy the initial position of an objective lens for optical disk by moving a fine shift stage by a fine displacement of a piezoelement. CONSTITUTION:A fine shift stage 14 and a rough shift stage 18 are moved up to an upper end and then moved down gradually to a position most approximate to a base board 5. In this case, a focus error signal is extracted out of a differential amplifier 8 of a focus error detecting part 9. The characteristics of the focus error signal are stored in a memory. Then both stages 14 and 18 are moved up by a step motor 19 and then moved down to a stored piezocontrol range DELTAl. Thus the drive of the motor 19 is stopped. Then a piezoelement 24 is charged and displaced slightly toward its contracting direction. The stage 14 is moved down slightly by the contraction of the element 24. The charging is stopped to the element 24 when the output of the amplifier 8 is set at 0. In such a way, the initial position is set for an objective lens 4.

Filed: 1989-09-13
Abstract: PURPOSE: To improve ductility/strength of solder joint, a method reducing a tin content of solder, by coating the flux, which contains a metallic compound having electronegativity stronger than Tin, to solder and heating the flux and the solder to the melting point of the solder or higher. CONSTITUTION: When flux is applied to a lead/tin solder joining pole and flux is heated to the fluidizing temp. of the solder or higher, lead or other metallic compound ionizes a tin atom in the solder to cause redox reaction with a tin atom, the tin is replaced with the lead from the flux. Lead or other metallic compound is dissolved in the flux to remove an alloyed tin from a solder composition. In this redox, a tin atom is oxidized, a lead ion is reduced, the tin in the solder is replaced with the lead from the flux. Lead acetate is used for a compound in the flux, a lead ion is reduced to a lead element, a tin element is turned to a tin ion forming lead acetate. By this method, because a sufficient quantity of tin for an initial solder composition can be added, the wettability is not deteriorated.

Title: Method and system for updating database
Inventor: CHIYANDORASEKARAN MOHAN
IPC: G06F17/30
Filed: 1990-09-07
Abstract: PURPOSE: To improve parallelism, to efficiently use a change content and to guarantee the consistency of a replica data base and an original data base by using peculiar ordering for recovery records on a transaction log. CONSTITUTION: The change processing of the replica data base is realized by dividing the REDO (re-issued) records from the transaction log of the primary data base into queues. The REDO records are divided so that all the transaction records in the transfer unit (page) of the primary data base are registered in the same queues 68 and 69 in a log sequence. The queue servers 68 and 69 apply the REDO records in the queues which the servers exclusively handle to the replica data base. Thus, the replica data base becomes consistent with primary data with a lock free update mechanism for processing the pages in parallel.
