Inventor: HIRAGA TAKASHI
IPC: B05B7/16
Filed: 1994-03-09
Abstract: PURPOSE:To produce high-function composite type optical thin films with high quality and high efficiency by spraying solutions of plural org. optical materials from spraying nozzles into a vacuum vessel for each of respective components to deposit these materials on a substrate and controlling the temp. of the substrate to a prescribed value by a heater. CONSTITUTION:The pressure in the vacuum vessel 3 is maintained under about 1X10<4> Pa by a vacuum pump 4. The solns. from liquid reservoirs 18 filled with the solns. of the plural org. optical materials are sprayed from the spray nozzles 1 for each of the respective components into the vacuum vessel 3 to deposit the thin films of the composite optical materials on the substrate 19. At this time, the substrate 19 is heated to a temp. not exceeding the thermal decomposition temp. of the deposits by using a substrate heater 8 and a substrate temp. measuring instrument 9, by which the evaporated components are removed. As a result, the high-function composite type optical thin films are produced with high quality at the low temp.

Abstract: PURPOSE: To eliminate a large operating force required when a manual operation of the valve is needed by a method wherein an emergency operation energizing mechanism is made possible permitting both connected or disconnected statuses.  
     CONSTITUTION: Under an emergency condition to shut off the valve in which only the 17th crutch 13 is engaged, the stopper 25 maintains a vertical posture of the pressure receiving member 22 against the energizing mechanism 24 when the operation is to be performed under a condition having pressure less than the dynamic pressure of the fluid. Oscilating displacement of the pressure receiving member 22 against said energizing mechanism 24 which is performed under an action of the dynamic pressure of an abnormal flow is electrically sensed by the mechanism 26, and the displacement sensing mechanism 26 and the releasing mechanism 18 are electrically correlated. Under such an arrangement as described above, when an abnormal flow is sensed by the pressure receiving member 22, a fixing of the stopper 16 is automatically released against the energizing mechanism 6 in cooperation with the sensing operation, and then the valve 4 is immediately stopped or shut off. When the valve body 2 is normally opened or closed, only the valve body 2 is opened or closed by a manual operation with the second crutch 32.

Abstract: PURPOSE:To prevent the decrease in the long term reliability of a laser oscillator due to the mixture of oil mist in gas circulating system by controlling to exhaust gas in the gas circulating system from an oil tank of a circulating pump or from the gas circulating system at the leakage time. CONSTITUTION:A leakage valve 8 is closed by a sequence controller 11, the operation of an exhaust pump 6 is started, the valve 7 is opened, and gas in the system is evacuated. Since the gas is exhausted through an oil tank 35, it is not necessary to contaminate in the system with oil mist. A gas supply valve 9 is closed at the stopping time, and a circulating pump 3 is stopped. The valve 8 is opened, and the valve 7 is gradually closed, and the pump 6 is stopped. When the leakage valve 8 is opened, gas (air) is introduced into the system, but since the valve 9 is closed so as to maintain the state that the pressure in the oil tank 35 is lower than the gas pressure in the pump, oil mist in the tank 35 does not reversely flow into the gas circulating system.

Moreover, a detected signal of the detector 5 is compared with a reference defect decision level 12 and the signal is processed and the defect is decided by a signal processing circuit 6. Next, when the conveying speed of the material 2 to be detected is changed, the conveying speed of the material 2 to be detected is detected and the level 12 to detect the defective part by the circuit 6 is corrected by a heating time correction circuit 9. Moreover, the variation of the heating attenuation time when the material 2 to be detected is conveyed between the equipment 3 and the detector 5 is corrected by a heating attenuation time correction circuit 10.

Abstract: PURPOSE:To form a panel switch which is operated as a switch by the contact between transparent conductive films when a transparent glass plate is depressed, by providing spacers which hold and fix two, front and rear transparent glasses, to which transparent conductive films adhere, at a minute interval. CONSTITUTION:A transparent conductive film (nesa film) is stuck to one face of a thick transparent glass 8 to form back electrodes 10a-10c in a form of lines, and the nesa film is stuck to one face of a thin transparent glass plate 7 in a form of columns to form front electrodes 9a-9d. Spacers 11a and 11b are inserted between transparent glass plates 7 and 8 to hold the interval between them constant. Matrix contacts are constituted in this manner; and when a prescribed position of the thin transparent glass plate 7 is depressed, electrodes in corresponding positions of transparent glass plate 7 and 9 are brought into contact with each other, and the depressed position is detected electrically. Thus, the switch operation is possible without the degradation of the display quality in the rear even if this panel switch is mounted on the front of a CRT, and goods difficult to flaw and easy to clean are obtained because the transparent glass plate is used in the front.
