Title: Focusing servo device for optical disk player
Inventor: NIKI SANPEI
IPC: G11B7/085
Filed: 1994-03-28
Abstract: PURPOSE:To improve the locking of focusing servo. CONSTITUTION:The focusing servo device of an optical disk player comprising a focusing control part 20 forming a focusing error signal having a sigmoidal characteristic and controlling the drive of a focusing actuator 10 is provided with a voltage generating means 30 supplying a sawtooth wave-shaped voltage to the focusing actuator 10 for gradually bringing it close to a disk 7. A changeover means 31 arranged between the focusing control part 20 and the focusing actuator 10 alternatively selects the focusing control part 20 and the voltage generating means 30. Adding means 34, 35 inputting the level of the digitized focusing error signal of the focusing control part 20 successively add the levels of focusing error signals. When the added value of the adding means 34, 35 is larger than a reference value, a comparing means 37 having a reference value makes the changeover means 31 change from the voltage generating means 30 to the focusing control part 20.

Abstract: PURPOSE:To provide a medical tape or sheet which is adhered to a skin, a mucous membrane, various medical tubes and has antibacterium by a method wherein a composition prepared by blending a water soluble silver compound in cation type natural rubber latex produces a pressure sensitive adhesive. CONSTITUTION:In a medical tape or sheet, a composition prepared by blending a water soluble silver compound in cation type natural rubber latex produces a pressure sensitive adhesive. In preparation of cation type natural latex, approximate 1 - 5wt%, based on a rubber content, a cation type surfactant or nonion type surfactant is added to normal natural rubber latex (rubber content concentration of 50 - 60% and pH of 9 - 11), and proper inorganic acid or organic acid is added to reduce pH to 3 or less. Silver salt and protein silver are preferably listed as an employed soluble silver compound. A preferable mixing amount of the water soluble silver compound is generally 0.1 - 30wt%, based on a rubber content of latex, silver. When a mixing amount exceeds 30wt%, viscosity of a pressure sensitive adhesive is deteriorated, and when it is lower than 0.1wt%, antibacterium is difficult to provide.

Title: Electrolytic cell of water using solid polymer electrolyte film
Inventor: KONDO MASAYOSHI
IPC: C25B9/19
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To improve resistance against hydrogen embrittlement and to decrease electric resistance by applying a noble metal plating layer for prevention of hydrogen enbrittlement and for decrease in contact resistance on the cathode side face of a bipolar plate in contact with a cathode feeder. SOLUTION: A platinum plating layer 37 is formed on the cathode side of a bipolar plate 9. By this method, embrittlement by hydrogen can be prevented, and durability and safeness of the electrolytic cell are significantly improved, as well as the electric contact resistance of the cathode side is decreased, which improves the characteristics of the electrolytic cell. Further, a platinum plating layer 38 is also formed on the anode side of the bipolar plate 9. Thereby, production of an oxide film during electrolysis is prevented, which suppresses increase in the electric resistance and increase in electric contact resistance due to an oxide film. As a result, the electric resistance is decreased. Therefore, an electrolytic cell of water having more excellent electrolytic characteristics can be obtd.  For example, the electrolytic cell equipped with the bipolar plate 9 above described has smaller electric resistance and better characteristics than an electrolytic cell equipped with a titanium bipolar plate without plating.

Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a control unit for vehicle (ECU) with which the stop of power supply can be surely prevented just in the middle of reloading data in a reloadable non-volatile memory. SOLUTION: When a password code in a flash memory and a password code from a reloading device are coincident after the reception of a reloading request from the reloading device (S220: YES), the ECU provided with a microcomputer for executing reloading processing (S230-S260) for reloading all the data while including a control program in the flash memory supplies the power of a battery through a main relay whose contact is short-circuited when the ignition switch (IGSW) of a vehicle is turned on or a driving signal is applied. When the IGSW is turned on and operation is started at the same time, the microcomputer outputs the driving signal to the main relay and when the execution of reloading processing is completed and the IGSW is turned off (S270: YES), the output of the driving signal is stopped. Thus, even when the IGSW is turned off during the execution of reloading processing, the supply of power to the microcomputer is continued.
