Claims (8)

1대의 도전성 박막을 절연박막을 사이에 두고 중첩하여 나선상(螺旋狀)으로 권회하고, 상기 도전박막의 한쪽의 양단과 다른쪽의 임의 부에 각각 단자를 마련한 노이즈 필터에 있어서, 상기 도전성 박막의 적어도 상기의 한쪽을 자성도전체로 하는 것을 특징으로 하는 노이즈 필터.
상기 다른쪽의 도전성 박막이 철박으로 만들어져 있는 것을 특징으로 하는 특허청구범위 제1항 기재의 노이즈 필터.
상기 자성체(磁性體)의 도전성 박막이 다른 한쪽의 도전성 박막보다 넓은 것을 특징으로 하는 특허청구범위 1에 따르는 노이즈 필터(noise fiter).
상기의 노이즈 필터는 그 단면을 타원형으로 원통형상이 되게 형성하는 것을 특징으로 하는 특허청구범위 1에 따르는 노이즈 필터.
상기의 한 쌍의 도전성 박막을 2가지 모두 자성의 도전체 재료로 만든 것을 특징으로 하는 특허청구 범위 1에 따르는 노이즈 필터.
다음과 같은 공정으로 만들어지는 노이즈 필터의 제조방법. 한쪽 끝에 리이드 와이어(lead wire)가 연결된 도전성의 박막에 절연막과 자성의 도정체의 박막, 그리고 또 다른 절연막을 포개는 공정. 상기 포개진 것을 나선형(spiral form)으로 중심 둘레에다 감는 공정. 상기 자성의 도전체 박막의 다른쪽 끝에다가 또 하나의 리이드 와이어를 연결하는 공정. 보호재료로 노이즈 필터의 전체의 몸체를 피복하는 공정.
상기 노이즈 필터의 피복공정 전에 나선형으로 감은 노이즈 필터의 몸체를 압착(壓着)하여 그 단면이 타원형이 되게 하는 공정을 추가한 특허청구범위 6에 따르는 노이즈 필터의 제조방법.
상기 2가지의 도전성 박막을 모두 자성도전체 재료로 된 박막을 사용하는 것을 특징으로 하는 특허청구범위 6에 따르는 노이즈 필터의 제조방법.
※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
