  • Patent number: 7005642
    Abstract: An infrared sensor includes a stem, a thermopile element disposed on a component-mounting surface of the stem, a case for covering the thermopile element, an inner cap that covers the thermopile element in order to shield infrared rays generated by secondary emission from an inside surface of the case, and a thermo-sensing element disposed inside the inner cap. In the infrared sensor, the case includes an infrared ray transmitting window for transmitting infrared rays radiating from an object. The inner cap is thermally coupled to the stem by being disposed on the component-mounting surface of the stem, and includes an opening for passing the infrared rays from the infrared ray transmitting window of the case towards the thermopile element. The thermopile element is disposed inside a recess in the component-mounting surface or so as to be substantially surrounded by a highly thermally conductive substrate disposed on the component-mounting surface.

  • Patent number: 5296707
    Abstract: In order to detect the movement of a heat source over a widened range by using a reduced number of pyroelectric type infrared sensors, a sensor section includes two infrared detecting means X and Y. The area to be observed by the infrared detecting means X is divided into two zones A and B while the area to be observed by the infrared detecting means Y is divided into two single zones a and b. The single zones A and a are overlapped on each other to form an overlap zone (A, a). The movement of the heat source between the single zone B and the single zone b, between the overlap zone (A, a) and the single zone B and between the overlap zone (A, a) and the single zone b is judged to detect the movement of the heat source over the entire area to be observed by the sensor section. In such a manner, two infrared detecting means can cover three zones to be observed.
