COLOUR CATHODE RAY TUBE WITH AN ELECTRON GUN AND METHOD FOR MANUFACTURING SUCH A GUN

摘要

"Colour cathode ray tube with an electron gun and method of manufacturing such a gun." of the disclosure In-line electron gun structure for color cathode ray tubes in which the final focusing and accelerating electrodes each employ three in-line tapered, partially overlapping apertures in facing relationship, and at least one pair of integral electron beam correctors associated with the central aperture of the focusing electrode. Such structure is produced by deep drawing a workpiece having an hour-glass shaped hole for each corrector pair desired.
