Title: Power supply backup device
Inventor: HASUDA YUTAKA
IPC: G06F1/26
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To evade the destruction of BIOS data on a personal computer or a device based upon a personal computer by instantaneously backing up AC input power supply generated during the erasure or writing of data to a flash ROM stored with BIOS. SOLUTION: If input power supply is momentary broken, a battery 6 backs up the source voltage in the personal computer or device based upon the personal computer. A battery control part 5 controls the power supply of the battery 6. A battery power supply control part 7 controls a battery control part 5 during the erasure or writing of data to the flash ROM 2 stored with the BIOS to back up the source voltage in the device. A battery power supply control signal to the battery power supply control part 7 is controlled by software. Consequently, data in the flash ROM 2 can be prevented from being destructed.

Title: Hydraulic control device for belt stepless speed change gear
Inventor: SAWADA DAISAKU
IPC: F16H61/662
Filed: 1984-10-04
Abstract: PURPOSE:To avoid an unnecessary power loss of a hydraulic pump for increase in pressure by providing a relief valve between the second line oil path and the first line oil path, thereby to discharge working fluid to the first line oil path by an increase in the second line oil pressure. CONSTITUTION:When the moving stroke of a movable rotor 22 amounts to the maximum, differential pressure between the second line oil path 46 and an oil path 52 is extinguished. As a pressure-regulating valve 50 throttles a circulating sectional area, the second line oil pressure is suddenly about to increase. The pressure in the second line oil path 46 is increased to cause a relief function of the pressure regulating valve 50, so that working fluid in the second line oil path 46 is circulated to the first line oil path. Thus, increase in pressure in the second line oil path is checked to avoid unnecessary power loss.

IPC: G02F1/11
Filed: 1987-08-25
Abstract: PURPOSE:To improve the diffraction efficiency for incident light by specifying the length to which a line parallel to the propagation direction of laser light crosses a piezoelectric body. CONSTITUTION:The plane shape of an effective part for a transducer is so determined that the length to which the line parallel to a P axis as the propagation direction of the laser light crosses the piezoelectric body 2 decreases according to the distance from the P axis in the plane of a piezoelectric fitting surface. The effective part of the transducer where the power of an ultrasonic wave is converged on the center part of a laser light cut surface 4 operates so that the laser light having an intense power distribution at the center part is held off, thereby performing the diffraction or Q switching of the laser light. Consequently, the diffraction efficiency is improved, so the driving electric power may be small.

Title: Address detection system
Inventor: YAMADA WASAKU
IPC: G11B20/18
Filed: 1983-11-08
Abstract: PURPOSE:To perform securely highly reliable address detection for correcting an address error by sending out a load pulse and a clock for address changing to an address counter according to the error detection result of address information. CONSTITUTION:An error detecting circuit 1 detects whether an input address (a) has an error or not, and an error flag (d) is set to a high or low level according to whether the error is present or not. Then, a clock generator 3 applies the load pulse (e) to the address counter 4 with a synchronizing signal passed through a delay circuit 2 synchronously with the address (a) unless the error is present. When the error is detected, on the other hand, the last correct address is increased by one by the address counter 4 with a clock (f) outputted by the generating circuit 3 and the error is corrected securely to output the address from the counter 4. Consequently, the high-reliability address detection for correcting securely the error of the address is performed.

Title: Plating method
Inventor: TANIGUCHI KAZUHIRO
IPC: C25D21/12
Filed: 1988-08-26
Abstract: PURPOSE:To make current value per one sheet of object nearly constant regardless of number thereof and to sufficiently perform plating treatment by performing voltage control at the initial stage and the final stage of plating without performing current control and performing plating in combination with ordinary current control. CONSTITUTION:Plating treatment is performed by allowing constant voltage to flow and controlling current value until an initial object F is carried into a plating part 4 and carried out from this plating part 4. In other words, the current value is controlled by indirectly controlling voltage value. Further until the initial object F is carried out from the plating part 4 and also the last object F is carried into the processing line L of the plating part 4, namely when the objects F are thoroughly supplied to the line L of the plating part 4, plating treatment is performed by steady current. In the final stage wherein the last object F is carried into the line L of the plating part 4, plating treatment is performed by allowing constant voltage to flow and controlling current value. As a result, quantity of electricity is reduced and wastage of plating is eliminated and efficient plating treatment is performed without causing rise in cost. Further a loading part 2 and an unloading part 6 are shown in the figure, respectively.
