Title: Charging method for lead storage battery
Inventor: MORIMOTO YOSHINARI
IPC: H01M4/22
Filed: 1986-11-28
Abstract: PURPOSE:To forcibly form PbSO4 on a substrate and an active material affecting the self-discharge speed and suppress the self-discharge quantity of the active material in storage by discharging for a short time with a high current. CONSTITUTION:After an initial charge, the drying process is performed, thus the adhesion between a substrate of a positive electrode plate and an active material is deteriorated, but when dilute sulfuric acid is injected and a current is fed, this condition is changed, and a relatively active condition is obtained. After a charge is completed, a discharge is forcibly performed with a high current, e.g., 10C current (IC is a value indicating the 20-hour rate capacity), for a short time, e.g., 0.5 sec. Thereby, active PbO3 formed between the substrate and the active material can be discharged and stable PbSO4 is slightly formed on the surface of the substrate, and the action suppressing a self-discharge while a battery is left intact can be obtained.

Title: Endurable nozzle capable of maintaining low flame combustion to prevent shutoff by slight vibration and breeze
Inventor: TOKUDA MASANORI
IPC: F23D14/58
Filed: 1993-10-08
Abstract: PURPOSE:To prevent flames from dying out, resisting vibration or breeze even if they are slight flames by cutting off the head of a pipe-shaped nozzle made of a thin walled metal so as to produce acute angle, such as an injection needle. CONSTITUTION:As the head of a pipe-shaped nozzle 1 which is made of a thin walled metal is cut off at an acute angle, an ignition port 3 is long and slender and oval in shape, which forms a tip nozzle rear wall 4 equivalent to the shape and forms a sharp tip 2 as well. As a result, when an exhaust gas is ignitied, the tip nozzle rear wall 4 engulfs flames and performs a guidance role, thereby serving as a role of a wind breakage wall. Furthermore, the ignition port 3 widens a suction area of oxygen in an open air and helps the combustion of fire while the sharp tip 2 promotes the combustion and burns red-hot immediately. Therefore, the exhaust gas makes it possible to keep the ignition for a long time with the constant red-hot tip 2 and repeat the ignition unless the tip is cooled even if the flames are temporarily shut off with temporary vibration of a breeze.

Abstract: PROBLEM TO BE SOLVED: To make suppressible the power consumption without degrading the display quality of a liquid crystal panel by providing V/F circuits to respective output voltages which are supplied to a liquid crystal panel and providing control circuits changing driving powers of the V/F circuits with external inputs. SOLUTION: P-channel Trs 11, 12, N-channel Trs 21, 22 and an N-channel Tr 23 constitute a differential circuit respectively as active loads, a differential pair and a current source. Moreover, an output circuit is constituted of a P- channel Tr 13 and N-channel Trs 24, 25. A reference voltage VREF 3 applies the constant voltage based on voltage divided potentials V5, V1 to control the gate potential of Trs 23, 25.

Title: Optical head device
Inventor: YOSHIZAWA TAKASHI
IPC: G11B7/09
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To provide an optical head device capable of removing the effect of an offset component from a track deviation signal. SOLUTION: This optical head device has a photodetector 23 detecting track slippage by receiving the light beam whose light intensity of zero order diffracted light is large among the reflected light beams from an optical disk D and photo-electrically converting it. The photodetector 23 has a 1st order diffracted light and light receiving areas 23a, 23b, 23c and 23d having a shape removing the light receiving area of the 1st order diffracted light (the 1st order diffracted light from among beam spots given by the superposition of the 1st order diffracted light and zero order diffracted light). Since the difference between the added value of outputs of light receiving areas 23a and 23c and the added value of outputs of light receiving areas 23b and 23d shows an offset component, the offset component is removed from a track deviation signal being the difference between the outputs of the light receiving areas 24a, 24b. Consequently, stable tracking control is enabled.

Title: Ceramic green sheet with vias and manufacturing method of multilayer ceramic wiring board including the same
Inventor: SEKIDO KEIJI
IPC: H05K3/46
Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent via fillers such as inks from dropping from each of ceramic sheets of a ceramic multilayer wiring board, while ensuring considerably large via diameters even in very thin sheets, and improve the performance of a resulting IC package by enlarging the via diameter. SOLUTION: A back tape 10 is pasted to a ceramic green sheet 1, having vias 2 so as to close the openings of the vias on one side, a conductive ink 3 is filled in the vias 2 by screen printing, etc., to fill the holes, and the back tape 10 is peeled off after the ink 3 hardens, thereby preventing the via filler (ink 3, etc.), from dropping out of the sheet 1 in the via-forming step. Thus, it is possible to ensure a considerably large via diameter relative to a thin ceramic sheet, this reducing the resistance of conductive parts of an IC package and hence contributing to the improvement of the performance.

Title: Method of calculating averaged effective value and protective relay using the same
Inventor: EMURA TOKUO
IPC: H02H3/02
Filed: 1990-10-22
Abstract: PURPOSE:To obtain an effective value of a fundamental wave without error even for frequency variation by sampling a wave at each of time points where one cycle is equally divided, and using an arithmetic mean of the sampled value and the sampled at the time point where the phase is shifted by 90 deg.. CONSTITUTION:A current flowing in a line 11 is detected by a CT 12, insulated by an auxiliary CT 13, level-converted, and a high frequency component is reduced through a low pass filter 1. In a sample-and-hold circuit 2, it is sampled and held at a predetermined time. The sampled value im digitally converted by an A/D converter 3 is stored in a memory 4.

Even if the frequency of a current flowing in the line 11 is varied, an effective value having less error can be obtained by using the sampled values shifted by 90 deg..

Title: Path-setting device and navigation device
Inventor: SUZUKI SATOSHI
IPC: G01C21/00
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To enable a user to set a destination path including a passage path that the user desires and to enable the user to set the passage path easily. SOLUTION: A display device is provided with a touch switch. When a user traces 'a road map' being displayed on a screen with the fingers, the trace is detected by a touch switch. A passage path can be specified based on the trace. More specifically, the passage path can be set intuitively and easily, thus specifying an arbitrary section accurately. The specified section is clear as compared with a method for specifying a road type and a road name where the specification of the passage path is unclear. Also, the passage path itself is traced and can be specified as a trace easily, which differs from the case of the instruction of the passage point where a number of passage points needed to be specified to accurately transfer the user's intention and hence much time and labor were required.
