Abstract

본 발명은 간섭 발진형식의 공진주파수를 조절하는 방법에 관한 것이다. 본 발명은 초음파장치(1)에 응용되고 이 장치(1)는 두개의 대칭평면(8) 사이의 교차점위에 중앙에 위치한 구동장치(2)을 지니고 이 대칭평면을 밀봉장치가 분할한다. 밀봉장치(1)는 이 구동장치(2)를 포위하는 반작용 몸체(3)와 신장된 좁은 밀봉면을 지닌 호온(4)을 지닌다. 밀봉장치는 반작용 몸체(3)와 호온(4) 사이에 마디평면을 지니고, 이 평면에서 밀봉장치가 고정에지(7)에 의해 고정되어 있다. 밀봉장치의 기능에 부정적으로 영향을 주는 간섭 발진형식의 공진주파수가 대칭으로 위치한 홈(7)이 반응몸체(3)에 제공되게 위치되어 있다. 홈(9)은 반응몸체(3)에 제공되고 이 홈(9)은 간섭 발진전위와 변위가 최대인 장소에 위치한다.
