Title: Manufacture of polymer lithium secondary battery
Inventor: NARUMI KEISUKE
IPC: H01M10/0565
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery excellent in a charge-discharge cycle life by preparing paste by performing the dry mixing of an active material, capable of storing and releasing lithium ions with carbon black so as to obtain a specific surface area according to a BET method, and by making a negative electrode by applying the paste to a collector or a film forming sheet. SOLUTION: Dry of an active material with carbon black is performed so as to obtain a specific surface area of 2.6-3.3 m2/g according to a BET method. Thereby, the active material suitably intertwines with the structure of the carbon black, and the adhesion of the carbon black to the active material is enhanced. Therefore, reduction in the contact area between the active material and the carbon black is prevented by the expansion and contraction of a power generation element in conjunction with the progress of charge-discharge cycles, so that the conductivity of a negative electrode can be maintained. A positive electrode 1 comprises positive electrode layers 5 bonded to both surfaces of a porous collector 4, and the negative electrode 2 comprises negative electrode layers 7 bonded to both surfaces of a porous collector 6.  The power generation element is enclosed in a waterproof armoring material 11, and a positive electrode and negative electrode leads are made to come out.

IPC: C07C67/00
Filed: 1988-02-29
Abstract: PURPOSE:To efficiently and readily extract a carboxylic acid derivative, by treating an aqueous medium containing both the carboxylic acid derivative and biological ingredients with an organic solvent of a specified concentration at a specified pH to flocculate and remove the biological ingredients. CONSTITUTION:Firstly, the pH value of an aqueous medium containing (A) a carboxylic acid derivative of formula I (R1 is alkyl, aralkyl or aryl group; R2 and R3 are each H or alkyl group; n is 1 or 2) produced by e.g., biological asymmetric hydrolysis of a racemic carboxylic ester and (B) such biological ingredients as bacteria decomposed product, protein, nucleic acid or the like is adjusted to <=5. Thence, said aqueous medium is incorporated with an organic solvent such as a halogenated hydrocarbon, alcohol or ester so that the concentration is at or below the saturated solubility for said aqueous medium to flocculate the biological ingredients. Said biological ingredients are then removed, and the resultant aqueous medium is spiked with an organic solvent, thus extracting the objective carboxylic acid derivative.

Title: Piezoelectric element, actuator using the same, and ink-jet recording head
Inventor: SHIMADA KATSUTO
IPC: B41J2/055
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent a lattice defect at a piezoelectric film by constructing a structure with a lower electrode in direct touch with the piezoelectric film, constituting a part of the lower electrode in touch with the piezoelectric film of a gold or silver layer, and composing the piezoelectric film mainly of titanate lead zirconate. SOLUTION: A piezoelectric element formed on a silicon substrate via a silicon oxide film 12 has a layered structure of a lower electrodes 12, a titanate lead zirconate(PZT) film 22 and an upper electrode 23 sequentially from the side of the silicon substrate. The lower electrode 21 is in a three-layer structure of a titanium layer 24, a platinum layer 25 and a gold or silver layer 26 sequentially from the side of the silicon substrate. The gold layer 26 is in an islands structure having a plurality of islands separated from each other. The gold layer 26 can serve as a nucleus for growth of the PZT film 22, and is strongly orientated to a crystal face of an orientation. Since the gold layer has an approximate lattice constant to that of the PZT film 22, the gold layer can restrict a stress to the PZT film 22 when the PZT film 22 is formed.

IPC: B22D41/50
Filed: 1982-03-24
Abstract: PURPOSE:To detect the erosion and internal condition of a nozzle and to improve productivity by dealing with the same quickly, by inserting a heat shielding plate at right angles to the longitudinal direction of the nozzle in a hot state, irradiating an X-ray to the nozzle and detecting the same through the heat shielding plate in front of a detector. CONSTITUTION:A detector 2 is provided in the position faced to an X-ray  source, and a heat shielding plate 5 and an immersion nozzle 4 are set therebetween, whereafter an X-ray is irradiated thereto and the transmitted X-ray is detected with the detector 2. The internal condition is detected from the sectional image. A gamma ray may be used for an X-ray irradiating device 1, but the X- ray suffices in terms of handling, control and the material of the nozzle 4. Either a direct method or an indirect method is adaptable for the detector 2; the former is better in conversion efficiency hence resolution. A film 3 is installed roughly in the same position as the position of the detector 2, and is photographed. The plate 5 protects the device 1, the ray source, the detector 2, and the film 3 against the high-temp. nozzle 4.

Title: Bus sending circuit
Inventor: YAMAKI MASAAKI
IPC: G06F3/00
Filed: 1988-02-29
Abstract: PURPOSE:To prevent the data identification error of a receiving circuit to receive data by sending a signal at a level in accordance with the settled level of a data bus for some time after valid sending data are sent. CONSTITUTION:After the significant data of a sending data SD1 are sent to a data bus 2, non-significant data are sent for a time th and the signal at an 'H' level is sent onto the data bus 2 for the th time after the significant state of a sending signal SD is terminated. Consequently, a rise time tTH when the data bus 2 is settled from an 'L' level to the 'H' level as high impedance can be shortened when the impression of an output enable signal is terminated. Thus, even when the rise time tTH changes by the increase of stray capacity by the number of substrates, the size of the resistance value of a pull-up resistance, etc., the recognition error of the receiving circuit can be prevented.
