Abstract
Description
상기 변환기(10)는 미국특허 6,222,305호에 개시된 기본 기술을 이용하여 구성된다. 만약 주석이 부착층(70)으로 사용된다면, 주석의 보다 높은 용융점이 고려되어야 한다.
도 11은 도 4의 변환기(10)의 변형예를 도시한 것이다. 도 11에서, 전술한 구성요소와 동일한 구성요소들은 동일한 식별번호로 표시된다. 도 11은 변환기(10)가 쐐기형상(90)을 갖는 제1 크리스탈(182)과 쐐기형상(90)을 갖는 제2 크리스탈(184)로 구성되는 것을 보여준다. 이 실시예에서, 변환기(10)는 표면(104)의 직경을 가로질러 연장된다. 각 크리스탈(182,184)은 도 4를 참조하여 설명한 바와 같이 공진기(14)에 부착되며, 같은 방법으로 작동된다. 크리스탈(182,184)은 도 7을 참조하여 설명한 바와 같이, 사각형 형상으로 형성될 수 있으며, 쐐기형상(90)은 층 82 및 76에 쐐기형상(90)을 부여하여 분할될 수 있다. 유사하게, 크리스탈(182,184)은 도 9 및 도 10을 참조하여 설명한 바와 같이 세그먼트화(분할)될 수도 있다.
