Abstract

A PROCESS FOR MANUFACTURING A COLOR PICTURE TUBE CAPABLE OF MINIMIZING THE THERMAL DEFORMATION OF THE SHADOW MASK IN DISCLOLSED.A GETTER 7'',7'',7''' IS FILLED WITH A BA MATERIAL 10, A HIGH OR LOW VAPORIZING MATERIAL 11,11'' HAVING A DIFFERENT VAPORIZING TEMPERATURE COMPARED WITH THAT OF THE BA MATERIAL 10,AND THE GETTER 7'',7'''',7'''''' IS INSTALLED WITHIN THE COLOR PICTURE TUBE. THE GETTER 7',7'',7''' IS HEATED BY A MICROWAVE HEATING MEANS, SO THAT THE BA MATERIAL 10 SHOULD BE VAPORIZED SO AS FOR THE VACCUM LEVEL OF THE COLOR PICTURE TUBE TO BE RAISED, AND THEN THE HIGH OR LOW VAPORIZING 11,11'' SHOULD BE VAPORIZED AND COATED ONTO AN ALUMINUM FILM 2 OF A PANEL 3 OR ON THE SURFACE OF THE SHADOW MASK 5. THIS VAPORIZING MATERIAL LAYER COATED ON THE ALUMINUM FILM 2 OR ON THE SURFACE OF THE SHADOW MASK 5 ABSORBS THE HEAT GENERATED BY THE SHADOW MASK 5, SO THAT THE THERMAL EXPANSION AND THE THERMAL DEFORMATION OF THE SHADOW MASK 5 SHOULD BE INHIBITED THEREBY IMPROVING THE COLORMETRIC PURITY OF THE PHOSPHOR SCREEN AND EXTENDING THE LIFE EXPECTANCY OF THE COLOR PICTURE TUBE .
