Description

음극선관 및 그 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 칼라 화면 표시용 음극선관,
제2도는 자기 4중극 렌즈에 의한 촛점 설명도,
제3도는 본 발명의 원리 설명도,
제4도는 본 발명에 따른 마스크장치,

Claims (3)

  1. 진공 엔벨로프 장치내에서, 다수의 전자빔을 발생시키기 위해 서로 다른 칼라의 형광 영역을 다수 구비하고 있는 디스플레이 스크린과, 각 전자빔이 하나의 칼라 형광영역과 관련되도록 다수의 애퍼츄어를 구비하고 있는 망간 철 플레이트로 만들어진 칼라 선택장치와, 각 애퍼츄어내에 자기 사중극 렌즈가 설비되도록 자화된 상기 플레이트를 구비하는 칼라 화면 표시용 음극선관에 있어서, 망간 철 플레이트는 불순물을 계산하지 않았을 때 25 내지 27% 무게의 크롬과 10 내지 11% 무게의코발트와 그 나머지는 기본적으로 철을 구비하는 Fe-Co-Cr 합금으로 이루어지는 금속박으로 형성되는 것을 특징으로 하는 음극선 관.
  2. 제1항에 청구된 음극선관에 사용하기 적합한 자화 망간철 플레이트 제조방법에 있어서, 평평한 플레이트는 불순물을 계산하지 않았을 때 25 내지 27% 무게의 크롬과 10 내지 11% 무게의 코발트와 나머지는 철로된 Fe-Co-Cr합금으로 형성되며, 여기에서 플레이트내의 애퍼츄어는 상기 플레이트가 자화 어닐링된 후에 부식되고 자화되어, 요구된 곡면형으로 형성된다는 것을 특징으로 하는 방법.
  3. 제2항에 청구된 방법에 있어서, 자화 어닐링은 다음과 같은 단계:즉, 650℃ 이상의 온도에서 합금을 유지시킨다. 온도를 550℃ 이하로 낮춘다, 550℃ 이하의 온도에서 합금을 유지시킨다; 를 구비하여 온도의 감소는 다양한 냉각율을 갖는 여러 단계내에서 대체로 지수적인 방법이나 선형적인 방법으로 발생하게 되는데 여기에서는 지수적인 감소에 가깝다는 것을 특징으로 하는 방법.
    ※참고사항:최초출원 내용에 의하여 공개하는 것임.
