Title: Valve and packing thereof, valve packing inspection method and inspection device therefor
Inventor: KOIZUMI HIROTO
IPC: G01N23/18
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an inspection method, an inspection device, its valve, and its packing which can confirm a packing condition in a valve with no opening, and inspect in real time even during operation. SOLUTION: The wall thickness (d) of a valve body, which surrounds the packing inserting part of a valve is formed as small as possible uniformly, and a packing, which is inserted in the valve, is combined with a member whose X-ray absorption coefficient is high or the like. It is thus possible to obtain an X-ray generator 8 which is loaded on a portable type carriage so as to be movable vertically by a lifter 9, an X-ray detector 11, which detects transmitted X rays, and an X-ray radioscopy shot image of the packing by the inspection device for valve packing, which is of a portable type and involves an image processing device 14, which conducts a prescribed image processing from a detected signal, and a monitor 15, thus allowing the image of the packing inside the valve to be outputted to the monitor even in a non-opening condition in real time for inspection.

Title: Failure examination device of evapopurge system
IPC: F02B77/08
Filed: 1992-03-16
Abstract: PURPOSE:To examine abnormal operation of an evapopurge system without being affected by a state of fuel evaporation by deducting an amount of pressure which is changed by fuel vapor, and judging whether there is leak or not from the pressure which is changed when negative pressure is supplied to the evapopurge system and thereafter it is sealed. CONSTITUTION:A pressure detecting means 9 is provided in an evapopurge system to detect a pressure from a fuel tank 13 to a purge path 4. This system is provided with a first valve control operation means 10, a second valve control operation means 11 and a judging means 12. The first means operates a first change rate of pressure when it changed to positive pressure, the second means operates a second change rate of pressure in the system under a negative pressure sealed condition and the judging means 12 judged that abnormality is caused when the difference between the pressure change rates is over a predetermined value. The pressure change which is caused by generation of fuel vapor at the time when the pressure in the system is the atmospheric pressure is substracted from the pressure change which is caused at the time of keeping the pressure in the system for a predetermined time. In this way, the amount of the pressure change caused by generation of fuel vapor is offset, whereby failure diagnosis is carried out without being affected by the state of fuel evaporation.

Filed: 1989-03-10
Abstract: PURPOSE:To obtain a sealing material generating no gap between it and an insulator consisting of sintered low expansion ceramics in the cooling procedure of connection process of the terminal electrode to the central electrode of a spark plug by blending an insulating ceramic filler of specified physical properties, a conductive filler and glass in specified ratio. CONSTITUTION:A sealing material is blended with 20-35wt.% of insulating ceramic filler of less than 7.7X10<-6>/ deg.C in thermal expansion coefficient, 10-30wt.% of conductive filler and 35-70wt.% of glass. Thereby the thermal expansion coefficient of the sealing material can be reduced, so that when the rear end of the central electrode 4 is heat sealed to the tip end of the terminal electrode 5 in an axial hole 31, the shrinkage of the sealing material can be reduced and the generation of gap between the insulator and the sealing material can be prevented to improve the adhesiveness. Because of excellent adhesiveness, even when a spark plug 100 is subjected to repeated mechanical shocks, the contact of the terminal electrode to the central electrode cannot be broken to keep the sealing to the axial hole 31 and the conducting circuit reliably.

Title: Manufacture of semiconductor device
Inventor: SEKI ISAO
IPC: G03F7/38
Filed: 1990-03-09
Abstract: PURPOSE:To prevent resist exfoliation generated after exposure or development, by a method wherein, when a mask coated with a protecting film is closely brought into contact with a rsist-spread wafer and exposure is performed, the film is closely brought into contact with the wafer after the protecting film surface is subjected to dry etching. CONSTITUTION:When a mask 1 coated with a PVA film 4 is subjected to plasma etching (isotropic etching), uneveness on the film 4 surface becomes deep. When the resist surface of a wafer 2 is brought into contact with the film 4 and exposure is performed, the contact area of the film 4 and resist 3 becomes small, and the mutual over contact can be prevented, because the unevenness of the film 4 surface is deep. Hence resist exfoliation after the resist 3 is brought into contact with the mask 1 can be prevented. That is, in the case of contact exposure, the resist exfoliation after exposure or development can be prevented, and the manufacturing yield can be improved. Further resist reproduction ratio (resist re-spreading ratio) is decreased, and throughput can be improved. Patterning properties of the resist also can be improved.
