Abstract
PURPOSE:To reduce the dispersion in the sharpness of picture, by minimizing the wallo and beam diameter of a cathode ray tube, through the determination of the position of the limiting aperture based on the main lens by using the absorption set. CONSTITUTION:In assembling the limiting aperture 14 on the electron gun constituent 6 with the use of the weldering tool 16, the limiting aperture 14 is absorbed with the tip of the welder electrode 19 while absorbing air through the suction pipe 17, the electrode 19 is inserted to the electron gun constituent 6, the stopper 18 after adjustment for the position in advance is in contact with the fifth grid 11, the limiting aperture 14 is placed at a given position, and it is welded in the third grid 9. Accordingly, the location of the limiting aperture 14 to the main lens is fixed to the main lens with good accuracy.
