Filed: 1988-05-13
Abstract: PURPOSE:To obtain an electrolyte for an Li secondary cell with excellent charge and discharge characteristic of an Li electrode by adding Li2CO3 to a nonaqueous electrolyte solved with Li salt as a solute in a solvent containing at least one kind of cyclic ester. CONSTITUTION:LiClO4 or the like is solved as a solute in a solvent containing at least one kind of cyclic ester expressed by the structural formula 1 or 2, where R1, R2, R3=H, CH3, CH2CH3, (CH3)2CH, OCH3, OCH2CH3, O(CH3)2CH. A nonaqueous solvent constituted of carbon and H or N, e.g., r-lactones, is mixed in this solvent, Li2CO3 is added in the oversaturated state. Ethylene carbonate, cyclohexanone or the like is used for the solvent expressed by the structural formula 1 or 2. The solvent is reacted with Li to form Li2CO3, but Li2CO3 is added to the electrolyte, the reaction between Li and the solvent is suppressed, the consumption of Li which can be used for the charge and discharge reaction is suppressed. The electrolyte for an Li secondary cell with good charge and discharge characteristic of an Li electrode is obtained.

IPC: H01L33/08
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To realize a printer wherein light-emitting parts on one semiconductor substrate and light-emitting parts on the other semiconductor substrate are arranged close to each other, and hence a high-accuracy printing which is required by the market, such as a printing density of 1200 DPI, can be achieved.

Title: Data registration retrieving method
Inventor: HIRABAYASHI SATOSHI
IPC: G06F17/30
Filed: 1983-06-28
Abstract: PURPOSE:To register a lot of data, and also to execute a retrieval at a high speed by providing an index table, and detecting and retrieving an address of a block in which a registration of a data to be retrieved is forecast. CONSTITUTION:When a retrieving whether some data is registered or not, first of all, an address of a sector in which a registration of a data to be retrieved is forecast is detected by an index table provided in a main storage device. This detection can be executed by comparing the heat registered data A arranged in order of the number in the index table, with a size of a data to be retrieved. The registered data of the sector of this detected address is transferred to a buffer area of the main storage device, and whether the data to be retrieved exists in the registered data of this sector or not is retrieved. According to such a retrieval, it is unnecessary to execute a retrieval by executing an access to other sector, therefore, the access time, namely, the time required for the retrieval can be shortened, and a lot of data can be registered.

Title: Liquid pressure controller of automatic transmission for vehicle
Inventor: FUJITA KENJIRO
IPC: F16H61/00
Filed: 1993-05-19
Abstract: PURPOSE:To prevent that the atmospheric pressure dots on pressure liquid of a discharge passage so as to secure sealability by closing the discharge port of a discharge passage extending from a changeover valve by means of a check valve when the changeover valve which supplies and controls pressure liquid to the frictional engagement element of an automatic transmission is switched to its halt position. CONSTITUTION:When a solenoid valve 24 is switched to its halt position by means of a controller 44, and the output port 30 and the discharge port 32 of a valve body are mutually connected, pressure liquid supplied to the pressure chamber 16 of a clutch 2 is discharged to a discharge passage 60 via the solenoid valve 24. Therefore a clutch piston 14 is forcibly pushed back by a return spring 20, and then frictional engagement between a clutch plate 8 and a clutch disc 10 is released. When a pressure in the discharge passage 60 is decreased less beyond the valve opening pressure of a read valve 70, a discharge port 63 of a trap box 64 is shut by the reed valve 70. As a result, since the pressure liquid in the discharge passage 60 does not receive the atmospheric pressure, proper sealability can be secured.
