Claims (3)

  1. 시청용 스크린과 축으로부터 자기적으로 편향될 수 있지만 음극선관의 중심축에 배열되고 후부로부터 스크린에 방향된 충전입자비임을 발생하는 수단과, 축방향으로 배열된 와이어 세그멘트에서 나온 자기성분 및 상기 축에 관하여 원주로 배열된 와이어 세그멘트에서 나온 자기성분을 갖는 평향코일이 코일의 전면에 분포된 그물자계를 상승시키고, 상기 스크린 전면에 상기 분포된 그물자기방사를 감소시키는 음극선 장치에 있어서, 자기분로 수단은 상기 코일과 상기 스크린 사이에 배치되고, 상기 자기분로수단은 상기 코일의 전면에 분포된 상기 그물자계를 최소화시키도록 선택된 상기 코일에 관한 구성 및 위치를 갖는 자기적으로 침투성 있는 물질을 포함하는 것을 특징으로 하는 음극선 장치.
  2. 제 1 항에 있어서, 상기 자기분로수단은 상기 중심측상에 집중된 자기적으로 침투성 있는 코일의 링을 포함하는 것을 특징으로 하는 음극선 장치.
  3. 제 1 항에 있어서, 상기 자기분로수단은 구성 및 위치에 대한 실효 mu가 유효 mu에서 작은 양의 변화가 되도록 투자율을 갖는 선형 페라이트로 구성된 부품을 포함하는 것을 특징으로 하는 음극선 장치.
    ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.
