Title: Processed red blood-corpuscle and its manufacturing method
Inventor: FUKUDA HIROSUKE
IPC: A61K35/18
Filed: 1987-10-20
Abstract: PURPOSE:To obtain a processed red blood-corpuscle with added stability while the natural antigen property thereof is maintained, by processing a natural red blood-corpuscle at moderate temperatures with a fixing agent of low concentration. CONSTITUTION:It becomes possible to obtain such processed red blood-corpuscle that maintains its natural antigen property, and has added stability, by processing a natural red blood corpuscle by a fixing agent of low concentration. The natural red blood-corpuscle referred to above is a red blood-corpuscle of a man, cow or sheep, etc. and is raw without being processed by, for example, fixing treatment or treatment with the use of a reducing agent. The natural red blood-corpuscle is processed in a solution of a fixing agent in a predetermined range of concentration generally at 4-40 deg.C or so, preferably at approximately 20-30 deg.C for about 1-10min. As a result, the processed red blood- corpuscle represents no inferior to-be-coagulated property and remarkably superior stability in preservation to the raw red blood-corpuscle, which is, therefore, particularly useful for detection of an antibody of a blood group.

IPC: F02P17/12
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To make the position of a misfire decision section proper to both of low and high rotation areas and to ensure high misfire detecting precision throughout a whole rotation area by changing the position of a misfire decision section (a crank angle) according to an engine rotation speed. SOLUTION: An engine control circuit 22 computes a fuel injection amount and an ignition timing according to various engine control programs stored at an ROM 24 to control operation of an engine 11, and the presence of the misfire of each cylinder is decided according to a misfire decision program stored at an ROM 24. Namely, during operation of an engine, the time of a misfire decision section is integrated from the pulse interval of a crank angle signal outputted in a misfire decision section. By calculating a difference therebetween through comparison of the integrating result with the time of a preceding misfire decision section, a rotation speed fluctuation amount is computed, and when a rotation speed decrease amount exceeds a misfire decision value, it is decided that the misfire occurs. This constitution improves misfire detection precision throughout a whole rotation area.

Title: Air bearing
Inventor: TAJIMA TAKUJI
IPC: F16C32/06
Filed: 1990-10-05
Abstract: PURPOSE:To prevent critical damage of a bearing caused by the moisture of supplied compressed air by forming a detecting part, provided with a gap larger than a gap between a land part and a shaft, at one end of the bearing, and detecting the change of the gap between the detecting part and the shaft. CONSTITUTION:A detecting part 6 is provided at one end of an air bearing 1, and a detector 7 positioned at this detecting part 6 is supported by the air bearing 1. A gap (g) between a land part 2 and a shaft 8 is set to be smaller than a gap G between the detecting part 6 and the shaft 8. Compressed air is supplied into a pocket 3 from a supply port 4 through a throttle part 5, and the shaft 8 is driven/ rotated while being positioned at the axis of the air bearing 1, so that the compressed air is sent out into air through the gap (g) between the shaft 8 and the land part 2. When the dehumidification of the compressed air becomes insufficient, water drops are attached to the shaft 8 and move in the axial direction of the shaft 8 so as to cross in front of the detector 7. Since the gap between the shaft 8 and the detector 7 is changed at this time, this change is detected. Abnormality of the air bearing 1 can be thereby discovered at an early stage to prevent critical damage.

IPC: H01P1/212
Filed: 1993-10-25
Abstract: PURPOSE:To improve spurious characteristics by parallelly connecting a laminated chip capacitor provided with a self resonance point in the spurious frequency which is the odd number multiple of a passing frequency to one of input/output terminals. CONSTITUTION:For the laminated chip capacitor C0 for improving spuriousness, a self resonance frequency is matched with the spurious frequency and the spuriousness is reduced by performing parallel connection. In this case, the spurious frequency is the odd number multiple of the passing frequency such as three-fold or five-fold. The disorder of impedance matching due to the addition of the laminated chip capacitor C0 can be corrected by a coupling capacitor C4. Also, the discorder of the impedance matching can be corrected by an inductor for matching parallelly connected to the laminated chip capacitor C0 for improving the spuriousness. Thus, the spurious characteristics can be improved without degrading passing characteristics.

IPC: H01G9/02
Filed: 1988-10-21
Abstract: PURPOSE:To provide an electrolytic solution having high dielectric characteristics and capable of presenting desirable performance in a wide range of temperature by dissolving a trimellitic anhydride or a salt thereof in an electrolytic solution in which a boric acid and an organic acid or a salt thereof are dissolved in solvents predominantly composed of an ethylene glycol. CONSTITUTION:Electrolytic solution is prepared by dissolving the trimellitic anhydride or a salt thereof in a solution of the boric acid and the organic acid or the salt thereof in mixed solvents predominently composed of the ethylene glycol. The trimellitic anhydride is preferably added in an amount of 0.1g or over to 100g of the mixed solvents. Accordingly, decrease of dielectric strength can be prevented even if a large amount of solute is added for compensating decreased resistivity of the electrolytic solution. Further, increased of resistivity in the atmosphere of high temperature can also be prevented since the electrolytic solution is thermally stable. As a result, lifetime of the products can be prolonged significantly.
