CATHODE-RAY TUBE

摘要

PROBLEM TO BE SOLVED: To provide an inner magnetic shield that reduces color slippage or color unevenness on the whole screen by reducing landing failure due to the distortion of the electron beam caused by the outside magnetic field such as earth magnetism. SOLUTION: The first skirt part 37 cuts vertically the gap 44 formed between the bending part 35 and the bar 41, and is welded at its bottom end by contacting the outside part 45 of the bar 41. The second skirt part 38 passes the outside of the welded part of the support member 42 of U-shape and the bar 41, and is welded by contacting the outside part 45 of the bar 41.
