| Zusammenfassung: | PROBLEM TO BE SOLVED: To improve quality and prolong the life of a cathode-ray tube by controlling adherence of a getter film to a shadow mask or a fluorescent screen by controlling gas redischarge or nonuniformity of brightness of the fluorescent screen due to adherence of the getter. SOLUTION: In an opening 10A formed in a magnetic shield 10 for introducing the getter, a scattering direction control member 17 is arranged for controlling a scattering direction of getter vapor scattering in a tube. |
