Title: Molten carbonate fuel cell
Inventor: FUJIMOTO SHIGERU
IPC: H01M8/24
Filed: 1988-02-16
Abstract: PURPOSE:To increase insulation by winding more than one belt-shaped fastening bands onto a manifold housing and fastening the fastening bands in the circumference direction to press each manifold housing against a stack through an insulating seal. CONSTITUTION:Manifold housing fastening bands 16 are wound onto a manifold housing 13, and fastened in the circumference direction to press the manifold housing 13 against the surroundings of a stack 11. When gas is supplied to the inside of the manifold housing 13 from a gas pipe 15, an insulation seal 10, arranged in the surrounding of the stack, of the manifold housing 13 tends to inflate by gas pressure. However, since the manifold housing 13 is fastened with the fastening bands 16, the insulation seal 10 uniformly presses the surroundings of the stack 11. The insulation seal 10 is uniformly brought into contact with the stack 11. Good insulation condition is thereby maintained.

IPC: H01L29/84
Filed: 1986-02-18
Abstract: PURPOSE:To reduce the temperature drift of the resistance value of a piezoresistor, and to measure acceleration with high precision by using a member having a thermal expansion coefficient approximate to a semiconductor base body as a stopper and separating a fixing support section between the stopper and a substrate from the piezoresistor in an extent that thermal stress can be ignored. CONSTITUTION:Both stoppers of an upper stopper 13 and a lower stopper 14 are formed from a material having a thermal expansion coefficient the same as or approximate to silicon. The peripheral section of the upper surface of the lower stopper 14 is bonded with an silicon base body 1 in a bonding section 16, and the thermal expansion coefficient of the lower stopper 14 is the same as or approximate to the silicone base body 1, thus hardly applying thermal stress to piezoresistors 5a, 5b from the silicon base body 1. The lower surface of the lower stopper 14 is bonded with a substrate 12 in a bonding section 17, but the area of the lower surface of the lower stopper is small, thus hardly transmitting thermal stress from the substrate 12 over the piezoresistors 5a, 5b. Accordingly, the resistance variation of the piezoeresistors 5a, 5b, the temperature drift of output voltage, is not generated.

Title: Driving circuit for display device
Inventor: TAKATO YUTAKA
IPC: G11C19/00
Filed: 1992-02-19
Abstract: PURPOSE:To prevent the degradation of the production yield of a display device due to a defect of a driving circuit by dividing each shift register array into plural blocks and transmitting the output of each block to the adjacent clock through a logic gate. CONSTITUTION:Plural outputs of shift register cells arranged in parallel are outputted through logic gates. Since the output of an OR gate is OR among input signals, the output of the OR gate is not affected by a defect to keep the function of the driving circuit normal even if this defect fixes the output of the shift register to time low level, for example, in a shift register block SR21. If a defect occurs which fixes the output of the shift register array to the high level, a normal signal is outputted to a probing pad P11 for examination but a normal signal is not outputted to a probing pad P21 for examination. Thus, the occurrence of the defect in the shift register block SR21 is detected.

Filed: 1992-02-19
Abstract: PURPOSE:To detect a defect, etc., of a product with a relatively simple hardware configuration by scanning image information of a specimen based on a chain code which is previously registered and judging whether it is normal or not. CONSTITUTION:A chain code which corresponds to a specimen 1 is created and registered by a chain code creation/storage part 13. Then, when the specimen 1 enters a visual field of a video camera 2, a sensor 4 detects it and a signal is sent to the camera 2 by an image take-in signal generation part 9. Thus, the camera 2 picks up an image of the specimen 1 and the image signal is converted by an A/D converter and is accumulated in an image memory 11. A pattern inspection part 5 scans an image data which was accumulated in the memory 11 based on the chain code, detection parts 14 and 16 detect whether a defect exists or not in the specimen 1, and judgment parts 15 and 17 judge whether it is a defective article or not. When it is judged or not judged to be a defective article, failure and pass signals are output, respectively.

Abstract: PURPOSE:To decrease the overall processing time and to reduce the overall system load with titled processing method by adding an algorithm making use of the preceding input value and a preceding area to the conventional characteristic function extraction processing algorithm and decreasing the number of times of calculations and extracting processes of the characteristic function respectively by means of said preceding input value and area. CONSTITUTION:The input value of this time is compared with the preceding input value and the calculated value of the preceding time is used directly as the result of calculation of this time as long as the coincidence is obtained from said comparison. Then the area of the input value data of this time is compared with an area to the input data processed in the preceding time. If the coincidence is obtained from said comparison, no characteristic function extraction is carried out. Thus the characteristic function extracted in the preceding time is used directly as that to the data of this time for execution of calculations. If the area of the data fetched in this time is out of the range of the preceding area, the searching is started at a place near said area not at the prescribed first point.
