  • Formation Of Various Coating Films On Cathode Ray Tubes And Lamps (AREA)

Abstract

PURPOSE:To prevent a cathode-ray tube from deformation, distortion, and/or destruction by heating the cathode-ray tube to a temp. below the distortion point of glass, by heating the front face of the panel over the distortion point necessary to form a reflex preventive film, and by forming reflex preventive film at the front face of the panel by normal pressure CVD method. CONSTITUTION:A cathode-ray tube 3 is heat treated in a gas exhaust furnace 1 to a temp. below the distortion point of the glass material for cathode-ray tube 3, for ex. 430 deg.C. This cathode-ray tube 3 is transported from the left to right on a belt conveyor 4 in a film forming chamber 2. Before application of No. 1 layer, covering surfaces over the panel 3a are heated by a heater 10 to 500-450 deg.C. Then film for No. 1 layer is coated, and also films for No. 2 and No. 3 layers, wherein the films are so formed that specified coefficient of refraction n is obtained. As the temp. of the covering surface in the case of No. 2 and No. 3 layers is 340 deg.C, there is no need to heat the covering surface, and the temp. is controlled by the gas exhaust furnace 1.
