본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 자기 차폐의 구조를 도식적으로 나타낸다,
제2도는 제1도에 따른 자기 차폐를 작동하기 위한 회로의 등가 회로를 나타낸다,
제3도는 제1도에 따른 자기 차폐에서 2개의 다른 자기 물질용 자기 유도의 기능으로서 역 투과 특성의 도식을 나타낸다.

Claims (5)

  1. 전기 코일(1,2)과 이 코일에 유도적으로 결합된 자화 성분(3)을 갖고, 자계를 외부 공간에 방사하며, 상기 자화 성분(3)의 자기 파라미터를 통해 전기적으로 스위칭 함으로써 상기 외부 공간 내의 자계를 스위치 온 및 스위치 오프되는 자기 차폐에 있어서, 상기 자기 성분(3)은 상기 코일(1,2)의 코어(1)의 재료를 포화하는데 필요한 유도에 관하여 작은 자기 유도에서 포화에 이르는 강자성 재료로 형성되고, 또한 자기 성분(3)이 포화에 이르는 자기 유도를 발생시키기에 충분한 펄스 전류의 자계를 발생하는 전류에 중첩 가능한 펄스 전압원을 코일(1,2)에 결합되는 것을 특징으로 하는 자기 차폐.
  2. 제1항에 있어서, 상기 코일(1,2)은 반 셀 형 코어 코일로서 설게 되어 있고, 상기 자기화 성분(3)은 상기 코일(1,2)의 오픈 측면에 놓여지고 나중에는 닫히는 성분인 것을 특징으로 하는 자기 차폐.
  3. 제1항 및 제2항에 있어서, 상기 자기화 성분(3)은 원뿔의 정점이 코일의 중심에 놓여 있는 방법으로 상기 반 셀 코어 코일(1)의 오픈 측면에 직면한 원뿔형 구조이고, 상기 반 셀형 코일 코어(1)는 자기화 성분의 원뿔형 형태에 오픈 측면에 정합 되는 것을 특징으로 하는 자기 차폐.
  4. 제1항 내지 제3항 중 어느 한 항에 있어서, 전기적으로 전도성인 금속 캐리어 하우징(4)에 적합한 동일 평면인 것을 특징으로 하는 자기차폐.
  5. 유도 근접 스위치로서 제1항 내지 제4항 중 어느 한 항에 청구된 바와 같은 자기 차폐의 용도.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
