Abstract
PURPOSE: To enable to manufacture bulbs with low cost not causing clearance between welded parts, by processing the plate glass into disc or square plate shape and welding it after inserting it at the inside of the tip cone bulb.
CONSTITUTION: In the electron tube bulb having flat face plate, the material 11 for the face plate flat and cylindrical and having outer diameter slightly smaller outer diameter than the inner diameter of the tip of the cone bulb 13 is prepared by cutting and processing the plate glass. The material 11 is held and turned with vacuum absorbing body 12, the bulb 13 is placed at a position close to it and coaxially, and it is turned. The circumference and the material 11 are heated and softened with the burner 14. Next, the bulb 13 is moved and the material 11 is inserted inside and further heated, and welding is made by using the iron 15 as required. Finally, the bulb 13 is slightly extended toward B while blowing 16, forming the electron tube bulb 17.
