- 청구범위 제1항에 있어서, 솔리드-스테이트 포로셀이 제로바이어스 광전방식으로 작동케 되어 최되 신호대 잡음비를 갖는 극히 높은 감도를 갖는 바의 광탐지장치.
- 청구범위 제2항에 있어서, 온도감지기와 포로다이오드가 이들 두 구성사이의 온도 차이를 최소로 줄이기 위하여 등온 영역내에 배치배는 바의 광탐지장치.
- 청구범위 제2항 또는 3항에 있어서, 온도감지기와 이득제어회로 조합으로 부터의 출력이 포토다이오드셀의 비직선성에 반비례하는 비직선형으로서 셀의 온도종속이 배제되는 바의 광탐지장치.
- 청구범위 제1항, 2항 또는 3항에 있어서, 전위필터 회로가 회로의 어느 단으로든지 잡음이 끼어드는 것을 방지하도록 제공된 바의 광탐지장치.
- 청구범위 제1항, 2항 또는 3항에 있어서, 원격한 장소로부터 표본 채취된 공기를 받아들일 수 있다 관상의 표본채취실, 이 표본채취실의 일측단에 착설된 광탐지기, 표본 채취실로 광선을 조사하는 광원과, 표본채취실의 타측단부에 착설된 광선흡수 수단으로 구성된 바의 연기탐지장치.
- 청구범위 제6항에 있어서, 표본채취실이 광원의 양측에서 표본 공기를 받아들이고 배출하는 바의 연기탐지장치.
- 청구범위 제7항에 있어서, 표본채취실이 이를 표본공기에 연통되게 하는 연결수단을 제외하고는 밀폐된 바의 연기탐지장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
