Title: Method and system for inspecting leakage
Inventor: ITO YOSHIHIRO
IPC: G01M3/20
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To decide whether a leak is present in an object to be inspected or not by supplying a reference gas different from a probe gas, taking out the reference gas mixed with the probe gas, detecting the concentration of the probe gas and calculating the leakage. SOLUTION: An object 10 to be inspected is placed in an inspection container 11 and a probe gas, i.e., a mixture gas of nitrogen and hydrogen, is supplied into the object 10. Consequently, residual gas in the object 10 is discharged through a probe gas discharge channel 27 and the object 10 is filled with the probe gas. A valve 18 provided in a reference gas supply channel 14 is then opened and nitrogen gas is set at the atmospheric pressure so that it flows into the inspection container 11. If a leaky part is present in the object 10, the mixture gas of nitrogen and hydrogen is mixed with the nitrogen gas in the air gap 21 of the inspection container 11. Consequently, the mixed gas is sucked into a circulation path 15 and the concentration of hydrogen gas is detected by a probe gas detector 12.

Title: Cooling method of cooling can
Inventor: KITAMOTO TATSUJI
IPC: C23C14/54
Filed: 1983-06-17
Abstract: PURPOSE:To cool effectively a can with a less refrigerant in the stage of cooling a cylindrical can for transferring a high polymer film on the surface of which a thin film of a ferromagnetic metal is to be deposited by evaporation by evacuating the inside of the can and evaporating the refrigerant with the inside wall surface. CONSTITUTION:While a high polymer film 3 of polyester, etc. is transferred by a cylindrical cooling can 4 under rotation in a vacuum vessel 1, a film deposited by evaporation is formed on the surface of said film by vapor flow 9 of the ferromagnetic metal in a crucible 7 by electron rays 6. The inside of the can 4 is evacuated in this case and a refrigerant such as water is evaporated under reduced pressure from the fine holes 15 on the inside surface of a water pipe 14 installed zigzag on the inside circumferential surface. The can 4 is effectively cooled by the heat of vaporization in such evaporation by which the can 4 and the film 3 in contact therewith are cooled with the smaller amt. of the refrigerant. The thin film of the ferromagnetic metal is thus stably deposited by evaporotion on the film 3 to a uniform thickness.
