Title: Manufacture of nickel-hydrogen secondary battery
Inventor: SUGANO KENICHI
IPC: H01M10/28
Filed: 1995-01-20
Abstract: PURPOSE: To easily manufacture a nickel-hydrogen secondary battery excellent in durability by mounting an electromotive-element portion inside a cylindrical outer case, injecting an electrolyte, temporarily sealing the opening of the case for initial charge at specified temperature, and then sealing the opening. CONSTITUTION: A stack consisting of a strip of positive electrode, a strip of separator, and a strip of negative electrode is wound to form an electromotive- element portion. The electromotive-element portion is mounted inside a cylindrical outer case open at one end and is electrically connected to external terminals. Then an electrolyte is injected into the cylindrical outer case from its opening, initial charge is effected at temperatures between 45 and 95 deg.C with the opening temporarily sealed, and then the opening is sealed with a sealant. Thus the evaporation and the splashing owing gassing of the electrolyte injected are avoided, and the charging efficiency of the positive electrode can be enhanced without damage to the negative electrode.

Title: Misfire diagnostic system of engine
Inventor: KOYANAGI YUTAKA
IPC: F02D45/00
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent wrong diagnosis of misfires by eliminating the specific influence of disturbances on the engine speed fluctuations reliably via a simple process. SOLUTION: Differences (VGi-VGi-1) between the output values of an acceleration sensor for sampling times dt in a prescribed period are integrated in S202 to provide a determination parameter X as a criterion of snatches. The determination parameter X is next compared with a determination threshold A in S203. If the determination parameter X is smaller than the determination threshold A, the decision that no engine speed fluctuations are specific to snatches leaves misfire diagnosis to continue. If the determination parameter X is not smaller than the determination threshold A, misfire detection for misfire diagnosis is canceled. When engine speed fluctuations specific to snatches occur by acceleration/deceleration or sudden road surface changes, false misfire detection is thus prevented reliably via such a simple process.

IPC: C07C17/00
Filed: 1989-01-13
Abstract: PURPOSE:To obtain the subject compound on an industrial scale at a low cost by isomerizing 1,1,2-trichloro-1,2,2-trifluoroethane and reacting the resultant 1,1,1-trichloro-2,2,2-trifluoroethane with HF in the presence of a catalyst.

Title: Fluid filled engine mount unit
Inventor: KAKIMOTO TOSHIHIKO
IPC: F16M7/00
Filed: 1982-01-20
Abstract: PURPOSE:To absorb effectively the low frequency vibration as well as high frequency vibration in an engine mount unit in which a fluid chamber and secondary chamber, which are partitioned with each other by a partitioning  plate, are filled with liquid, by providing a movable long cylindrical body in a  through hole of the partitioning plate. CONSTITUTION:In a fluid-filled engine mount unit in which a hollow space 3 is provided in a mount rubber 4 fixed between a base plate 1 on the power unit side and a base plate 2 on the car body side, and a partitioning plate 6 equipped with a through hole 6a is installed on either side of the said two base plates, forming a fluid chamber 9 and a secondary chamber 10 at the both sides of the partitioning plate 6, a long cylindrical body 18 which opens its one end in the said fluid chamber 9 and the other end in the said secondary chamber 10 each independently, is movably installed in the said through hole 6a.

Title: Manufacture of screw incorporated with washer
Inventor: GOTO TOSHIO
IPC: B21H3/02
Filed: 1985-01-18
Abstract: PURPOSE:To decrease the space between a seat face and the root end of thread peaks by subjecting screw blank having a screw head and stem part to pressurizing on the outside periphery of the screw head after rolling of the screw peaks in a process for production consisting of fitting a washer to the above-mentioned screw stock then rolling the screw peaks to the stem part. CONSTITUTION:The washer 4 is fitted to the screw stock 3 having the screw head 1 and the stem part 2. The screw peaks 5 are then rolled to the stem part 2. The space l between the seat face 6 and the root end 7 of the screw peaks 5 is equal to the natural length of the washer 4 or slightly longer than the same. The pull out of the washer 4 is thereby obviated as the bore of the washer 4 is smaller than the diameter of the peaks 5. However, the section of the peaks 5 is triangular and the bore of the washer 4 is larger than the effective diameter of the peaks 5 and therefore the washer 4 advances slightly from a peak-less part 8 of the stem part toward the peak 5 side and produces a space on the face 6 in some case. The outside periphery of the screw head 1 is thereupon subjected to the pressurizing to push down the face 6 and to decrease the space l to l'. The advance of the part 8 to an internal thread is thereby prevented and the decrease in the strength and durability is obviated even if the internal screw is thin.

Title: Braking control unit for vehicles
Inventor: IMOTO YUZO
IPC: F16D65/14
Filed: 1985-01-21
Abstract: PURPOSE:To make braking hydraulic pressure controllable so minutely without making a control unit into being oversize and complication, by installing a piezoelectric control piston in a wheel cylinder, while operating this piezoelectric control piston and controlling the braking hydraulic pressure. CONSTITUTION:In a normal state, a selector valve 28 is being opened whereby a brake piston 13 is operated by hydraulic pressure out of a master cylinder and braking is carried out. In time of wheel locking, high voltage is fed to a piezoelectric element of a piezoelectric mechanism 23 so that capacity of a piezo-piston 24 is set to the maximum. Simultaneously, a volumetric control piston also is moved in a direction where an oil chamber 20 is reduced. Under this condition, a selector valve 28 is closed, whereby oil is sealed in the oil chamber 20. Then, voltage to be fed to the piezoelectric mechanism 23 is made to be lowered, and when capacity of the piezo-piston 24 is reduced, the volumetric control piston 21 is moved in a direction where the oil chamber 20 expands. Therefore, braking pressure is reduced, thus the wheel lock is released free.

Title: Method of reliquefying liquiefied petroleum gas
Inventor: OKADA TAKEO
IPC: F17C13/00
Filed: 1982-01-22
Abstract: PURPOSE:To dispense with pressure feed equipment in a method of condensing self-evaporating gas into liquid with a condensor and returning the liquid to a storage tank by adjusting the liquid level in the condensor according to medium temperature to keep condensing pressure higher than head of liquefied gas in the storage tank. CONSTITUTION:Self-evaporating gas from low temperature liquefied gas storage tank 10 is supplied to a condensor 11 by a compressor 12. Temperature of cooling water supplied to the condensor 11 is detected by a detector 23 and when this temperature is detected lower than a predetermined one, control signals are generated from a temperature regulator 25 to a liquid level regulator 26 to compare liquid level of the condensate in the condensor 11 detected by a liquid level detector 24 with a set value for throttling controllably valve 22 and always keeping the liquid level in the condensor 11 higher than liquefied gas head in the storage tank 10. Thus, the condensate liquid in the condensor 11 will return with its own pressure to dispense with pumps.

Abstract: PURPOSE:To realize high time-division drive by using simple matrix drive at a normal frequency for driving a liquid crystal panel. CONSTITUTION:This device is composed of a transparent upper substrate 11 provided with transparent signal electrodes 21 in a row direction, lower electrode 12 provided with scanning electrodes 22 in a column direction and picture element electrodes 23 with a surface as a reflecting plane while being connected through an optical conductor 50 to the scanning electrodes 22 by providing a slender window 23a on the optical conductor 50, and liquid crystal 30 filled between both substrates by arranging the signal electrodes 21 and the picture element electrodes 23 while facing those electrodes each other. Therefore, when the quantity of received light at the optical conductor is increased or decreased to a certain level, the resistance is increased/decreased, a potential divided to the liquid crystal is rapidly increased/decreased, and a picture element can obtain a threshold value characteristic to be rapidly bright or dark. Since the optical conductor 50 receives light through the slender window, the capacity of the optical conductor 50 can be reduced so as to be almost ignored, and the high time-division drive of the liquid crystal panel is enabled.
