Abstract: PURPOSE:To form a suitable film and to improve the quality of a semiconductor integrated circuit by emitting a measuring light from a measuring unit to the surface of a board through a hole made at a gas supply unit, and measuring a film formed on the board upon reception of its reflected light. CONSTITUTION:An optical beam 17 is emitted from a film thickness measuring unit 16 perpendicularly to the surface of a thin film on a wafer 8 through a transparent window 15 and a gas injection hole 6 during a film forming process. The beam 17 emitted to the wafer 8 is reflected on the wafer 8, and the reflected light 17 is introduced again to the unit 16 through the hole 6 and the window 15. In this case, the wavelength spectral characteristic of the beam 17 is examined by using the unit 16 and the thickness of a thin film being deposited on the wafer 8 is measured in real time. Thus, when the thickness of the film on the wafer 8 is measured and the film is formed, the thickness of the film can accurately and stably be measured on the wafer 8 during film forming process, thereby accurately controlling the formation of the film.

Then the image signals are stored in a storage part 6 in the frictionized picture element units. Then an arithmetic part 7 counts picture elements having the same light-shade degree as to the digital image signals of one stored screen to find the light-shade degree histogram. Further, the arithmetic part 7 uses the minimum light-shade degree of the histogram as a threshold value to convert the image signals of one stored screen into binary signals, picture elements having the same value and adjoin to each other among the binary image signals are put in connection areas, and the internal quality of the metal piece is inspected by using the umber of picture elements and shape of the connection areas.

IPC: F25B1/00
Filed: 1987-09-30
Abstract: PURPOSE: To sufficiently recover a refrigerant by constituting a refrigerant circuit for by-passing a condensing pressure control valve by arranging a solenoid valve in parallel with the control valve. CONSTITUTION: When a water cooling and warming machine is operated normally, a refrigerant coming out of a compressor 1 is liquefied under a high pressure by means of an air-cooled condenser 2, supplied to a receiver 4 through a condensing pressure control valve 3, depressurized by means of an expansion valve 6 through a solenoid valve 5 for liquid, and returned to the compressor 1 after the refrigerant is gasified under a low pressure by means of a water cooler 7. While the machine is operated, a by-pass solenoid valve 9 is closed and the condensing pressure of the condenser 2 is maintained at a fixed value by adjusting the quantity of the refrigerant in the condenser 2 by opening and closing the control valve 3 at about a set pressure.  In addition, a by-pass valve 8 for gas works to maintain the pressure in the receiver 4 at a constant level by by-passing a gas from the compressor 1 side when the pressure of the receiver 4 becomes lower than a prescribed value. At the time of shifting the operation of the machine to refrigerant recovering operation, the whole quantity of the refrigerant can be recovered to the receiver 3 and the pipeline around the receiver 4 when the operation of the machine is continued by closing the solenoid valve 5 for liquid and opening the by-pass solenoid valve 9.

Title: Fuel cell
Inventor: WATANABE AKIRA
IPC: H01M8/24
Filed: 1989-09-20
Abstract: PURPOSE:To enhance the sealing property of a fuel cell with a relatively simple constitution and prevent the cross leak of gas by elastically deforming plate springs in such a manner as to curve one plate spring and horizontally bend the other plate spring, thereby applying pressing forces to adjacent mounting frames of manifolds for fuel gas and reaction air, by which pressing forces the mounting frames are pressed into contact with sealing material. CONSTITUTION:A manifold 3 for fuel gas and a manifold a for reaction air are independent of each other but their adjacent portions are connected to each other by two kinds of spring plates 5, 6. When both ends of a connecting manifold 8 are fixed to a cell stack 1 against the resilient force of each plate spring 5, 6 sufficient pressing forces are applied to the plate springs 5, 6 via a sealing material 12 so that the plate springs 5, 6 are elastically deformed in such a manner that one plate spring 5 is curved and the other plate spring 6 bent horizontally. Thus a good shield sealing portion is constituted between fuel gas and reaction air, thereby preventing a gas leak effectively. The manifolds 3, 4 for fuel gas and reaction gas are sealed independently of each other at their adjacent portions 31, 41 so that in the event of a gas leak a cross leak to the other side will not occur, which ensures safety. Thus the sealing property of the fuel cell is enhanced and a gas leak and its cross leak are prevented by the simple structure.
