Title: Secondary battery
Inventor: MATSUHISA ICHIRO
IPC: H01M10/05
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To detect a defective circuit voltage in a shipment inspection so as to improve battery quality by connecting all the batteries in the corresponding lot in parallel after initial charging for matching open circuit voltages with each other. SOLUTION: A negative electrode using carbon applied to a copper foil as a negative electrode active material and a positive electrode using lithium cobaltate as a positive electrode active material are wounded several times via a separator into a roll-shaped group of components. Constant current charging is finished when a battery voltage reaches 4.1 V. Subsequently, all the batteries in the same production lot are connected in parallel so as to be left standing, and the battery voltage match each other. After again is carried out further, an open circuit voltage inspection is carried out and only a secondary battery with a defective open circuit voltage is rejected. In this way, variation of an open circuit voltage is reduced, and a secondary battery causing minor internal short circuit can be easily selected so as to be removed.  Alternatively, matching of voltage may be carried out by performing parallel connection in aging or after aging.

Title: Two wheel driving device of motorcycle
Inventor: FUJIKAWA TETSUZO
IPC: B62M19/00
Filed: 1991-03-01
Abstract: PURPOSE:To ensure a function of automatic driving of a front wheel according to the slip condition of a rear wheel, and so on, so as to improve driving performance of a motorbicycle by connecting a hydraulic motor for driving the front wheel and a hydraulic pump rotated in proportion to the rear wheel, through a pipe, and whereby forming a closed hydraulic circuit. CONSTITUTION:A hydraulic motor 38 for driving a front wheel 1 is arranged on the front wheel 1. A hydraulic pump 35 rotated in proportion to the rotational velocity of a rear wheel 2 is connected to the rear wheel 2 in an interlocking manner, through an output shaft 5 of a transmission 3. The hydraulic pump 35 and the hydraulic motor 38 are connected together through a flexible pipe 41 for feeding pressure oil and a pipe 42 for returning oil, and a closed hydraulic circuit 18 is formed thereby. When a difference in the relative rotational velocity occurs between the front wheel 1 and the rear wheel 2 due to the slipping of the rear wheel 2, the driving force (front wheel driving force) of the hydraulic motor 38 is generated in the direction where initial rotational relationship is restored. The driving performance of the motorbicycle can thus be improved to a large degree.

IPC: H04N19/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide an image processing unit by which a reproduced image with high image quality is obtained in a short processing time. SOLUTION: A wipe means 111 applies wipe processing only to a DC component, included in a high efficiency code. A decoding means 110 decodes the DC component after the wipe processing and an AC component included in the high efficiency code. Thus, in comparison with a conventional configuration that applies wipe processing to the DC component and the AC component included in the high efficiency code after they are decoded, the arithmetic amount required for the wipe processing is very much reduced.
