Claims (4)
- 음극선관상에 배치된 편향요크를 통하여 필드 및 선편향 간격동안 필드 및 라인율 편향전류를 제공하는 수단을 내장하고 이는 비데오 표시장치의 음극선관용 디가우싱 회로에 있어서, 전압원(35,91)과, 상기 음극선관 주변에 배치된 다가우싱 코일(91)과, 실제상으로 0필드 편향전류의 지시로서 출력신호를 공급하는 수단(60,65,77)과, 상기 출력신호에 응답하여 상기 원을 상기 디가우싱 코일(91)에 결합하여 상기 디가우싱 코일(91)의 교류를 감소시키는 스위치수단(37,92)을 구비하는 것을 특징으로 하는 잔류자기가 없는 디가우싱 회로.
- 제1항의 회로에 있어서, 상기 출력신호 공급수단은 비교기(65,77)를 구비하는 것을 특징으로 하는 잔류자기가 없는 디가우싱 회로.
- 제1항의 회로에 있어서, 상기 스위치수단은 다이오드(9)와 병렬로 결합된 SCR(37)로 이루어지는 것을 특징으로 하는 잔류자기가 없는 디가우싱 회로.
- 제3항의 회로에 있어서, 상기 교류흐름은 상기 SCR(37)을 통하는 제1전류경로와, 상기 다이오드(92)를 통하는 제2전류 경로로 이루어지고, 상기 제1전류경로는 상기 제2전류 경로에 의해 허용된 반대방향으로 전류흐름을 허용하는 것을 특징으로 하는 잔류자기가 없는 디가우싱 회로※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
