IPC: G01M11/00
Filed: 1993-08-25
Abstract: PURPOSE:To detect the defect of a luminescent spot, etc., in a state near to visual observation by finding the picture element normal luminance level of an image fetched by dividing into plural images, and detecting the defect by calculating difference between the luminance level of each picture element and the picture element normal luminance level of the picture element. CONSTITUTION:The average of the luminance level of the picture elements that belong to areas PA-PC set in advance among the picture elements in image memory 4 are calculated and set as A-C, and the average of the addresses of the picture elements that belong to the areas PA-PC are calculated and set as (XA, YA) to (XC, YC). The equation of a shading plane is set as Z1=ax+by+ C, and a linear equation with three unknowns A=axA+byA+C, B=axB+byB+C, and C=axC+byC +C is solved, then, a to c can be found. Also, assuming the luminance level of the picture element with arbitrary addresses X, Y as Zz, the luminance level K can be found by equation K=Z1-Z2=Z1-(aX+bY+C), thereby, the luminance level of each picture element can be calculated. Thence, the picture element binarized setting a threshold value as reference is detected as the luminescent spot, and the defects of all areas of a display part 1a can be detected.

Title: Device for controlling automatic transmission
Inventor: SHIRAHAMA KATSUNORI
IPC: G05G5/00
Filed: 1988-08-24
Abstract: PURPOSE:To shorten energizing time to a solenoid by composing device which becomes conductive when both a supported bush and a foot brake are actuated, of a slice and of the solenoid which energizes the bush in such a way that a recessed groove is fitted in a position pin. CONSTITUTION:When a shifting lever 1 is rotated afterward so that a position pin 11 is parted from a parking range so as to be moved to the other ranges, the slice 23 of a bush 25 is slid afterward along the guide section B of the engaging port 6 of a position plate 3, and is concurrently slid upward along the shifting lever 1 so that the position pin 11 is engaged with a recessed groove 21. A solenoid 27 becomes non-conductive after a certain time has elapsed, which situation even allows the bush 25 to be pushed by spring force within the solenoid 27 in such a way as to be rotated while being controlled, but the bush 25 will never be rotated because the position pin 11 is engaged with the recessed groove 21 wherein the position pin 11 is arranged in such a way as to be freely moved up and down. This constitution makes it possible to make the force checking the movement of the position pin 11 good enough to only resist the force depressing a control button 19.

Filed: 1981-12-25
Abstract: PURPOSE:To obtain the uniform electromagnetic converting characteristics and at the same time to facilitate the process through a demodulating circuit, by specifying the length of the gaps of magnetic head cores packaged at the inner and outer circumference parts. CONSTITUTION:A magnetic disk 11 is divided into an inner circumference side track 13 and an outer circumference side track 14, and optimum core gap lengths g1 and g0 are obtained for magnetic heads 12a and 12b in order to obtain the same resolving power for the most inside circumference of the tracks 13 and 14 respectively. In this case, the constants are defined as eta1 and eta2 on the basis of the shortest recording wavelengths lambda1 and lambda0 which are recorded and reproduced at the inner and outer circumference areas of the heads 12a and 12b respectively. That is, g1<=lambda1X1/eta1 and g0<=lambda0X1/eta0 are satisfied, and at the same time eta0-1<=eta1<=eta0+1 by setting the gap lengths g1 and g0 respectively. Thus the electromagnetic converting characteristics such as the resolving power, the previous history characteristics, etc. can be unified at both the inner and outer circumference sides for a magnetic head.

Title: Fuel cell
Inventor: KOGAMI TAIJI
IPC: H01M8/02
Filed: 1985-09-27
Abstract: PURPOSE:To prevent heat generation and performance decrease caused by mixing of fuel gas and oxidizing agent gas by filling a sealant in which phosphoric acid is used as dispersion medium between the peripheral, parallel in a gas flow direction, of electrode and a separator. CONSTITUTION:A sealant 4 is filled on the stacked surface of the peripheral, parallel in a gas flow direction, of a ribbed electrode 2 and a separator 3. The sealant 4 can keep steady sealing ability for a long time by using phosphoric acid as dispersion medium. The sealant absorbs recessed and projecting parts on the surface of the periphery of the ribbed electrode 2 or the separator 3 and eliminates spaces between them to bring the periphery into close contact with the separator 3, and increases airtightness between them. Thereby, gas leakage is eliminated and mixing of fuel gas flow B and oxidizing agent gas flow C is prevented. Therefore, heat generation of cell stack and decrease in cell performance caused by these problems can be pervented.
