Filed: 1982-11-02
Abstract: PURPOSE:To obtain a shadow mask having good quality by composing the resistor layer against etching liquid with water soluble layer and another water soluble layer or non water soluble layer thereby protecting the opposite face of material formed with a hole section liquid tightly. CONSTITUTION:A section formed with larger hole of a shadow mask member 10 is shielded liquid tightly with a film 21 then etched until a small hole section 14 having predetermined diameter D3 is bored and washed with water thereafter water soluble material having resistance against etching liquid is sprayed into said section only through said section 14 under wet state to form first resistor layer 161. Then second resistor layer 162 is formed with water soluble or non water soluble material having resistance against etching liquid on the first resistor layer 161.

Abstract: PURPOSE:To prevent components from being damaged due to an abnormal discharge by highly setting laser gas pressure at the time of starting the application of a high voltage, altering it to a predetermined gas pressure after applying the high voltage, and suppressing power supply to a high voltage source by interlocking when the gas pressure is lower than a predetermined range. CONSTITUTION:A switch 28 is set to a high voltage side at the time of starting the application of a high voltage, a gas pressure controller 27 is controlled to close a switching valve thereby to suppress an exhaust gas amount to a vacuum pump 22, thereby altering it to a predetermined gas pressure. After a high voltage is applied, gas pressure in a laser discharge tube 21 is detected by a gas pressure detector 26 to be set to a predetermined gas pressure. Thus, it can prevent an abnormal discharge from occurring at the time of starting the application of a high voltage. Further, if the gas pressure in the tube 21 is lower than that at the time of normal operation, an interlock is so operated as not to supply power to a high voltage power source. Thus, the discharge is not started to obviate the damage of electric circuit components.
