Claims (5)

하나의 원통형 케이스안에 적외선이 통과할 수 없는 여과기가 있고, 여과기 뒷면에 초전소가(6)가 부착되어 있다.In one cylindrical case, there is a filter through which infrared rays cannot pass, and a supersinter charge 6 is attached to the back of the filter. 이 초전도(6)은 미세한 기압의 변동을 탐지한다. 초전도(6)과 여과기(4)사이의 공간은 외부의 공간과 연결되어 있다. 또한 이 여과기(4)에는 수 많은 구멍(11)이 나 있는 특징이 있다.This superconducting 6 detects a slight change in air pressure. The space between the superconducting 6 and the filter 4 is connected to the external space. In addition, this filter 4 is characterized by having a number of holes 11. 1의 조항에 덧붙여, 여과기(4)에 나 있는 구멍(11)의 직경이 초전도(6)의 표면지름의 10/1 정도가 된다는 특징이 있다.In addition to the provision of 1, the diameter of the hole 11 in the filter 4 is characterized by being about 10/1 of the surface diameter of the superconducting 6. 1,2의 조항에 덧붙여 검출기는 여과기의 구멍(11)이 외부에서 들어오는 빛이 구멍을 통해 초전도(6)의 감지 부분위에 비춰지지 않도록 나있는 특징이 있다. 이것은 초전도(6)의 감지부분 외곽에 해당되는 여과기의 표면위에 구멍이 나있는다는 것이다.In addition to the provisions of 1 and 2, the detector is characterized in that the hole 11 of the filter is designed so that light from outside is not reflected through the hole on the sensing portion of the superconducting 6. This means that there is a hole on the surface of the filter which is outside the sensing part of the superconducting 6. 1,2,3의 조항에 덧붙여 초전소가(6)와 차단기 사이의 공간의 높이가 초전소자의 윗면적의 지름에 해당한다는 특징이 있다.In addition to the provisions of 1,2 and 3, the height of the space between the pyroelectric element 6 and the circuit breaker corresponds to the diameter of the upper area of the pyroelectric element. 검출기는 위에서 말한 조항들에 덧붙여, 첫번째 차단기(4)의 뒤에 약간의 간격을 두고 제2의 여과기(3)가 동일한 방식으로 설치 되어 있고, 외부에서 침투하는 빛이 잇달아 첫번째 두번째 차단기를 통과할 수 없도록 구멍들은 서로 엇갈리게 나 있는 특징이 있다In addition to the provisions mentioned above, the detector is provided with a second filter 3 in the same way, with a slight distance behind the first circuit breaker 4, and light from outside can pass through the first second circuit breaker one after another. The holes are characterized by staggered features ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
