Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion in sensitivity, eliminate the need for correcting means, and reduce a cost by providing a semiconductor thin-film with a polycrystal comprising the crystal particle of smaller particle size than the film thickness of the semiconductor thin-film. SOLUTION: Each heat-sensing part 8 comprising a polycrystal silicon comprising a crystal grains 8a of the smaller particle size than the film thickness of the heat-sensing part 8. The percentage by which a grain boundary 8b occupies the element area of the heat-sensing part 8 is almost constant with all heat- sensing parts 8 while the percentage by which a carrier is trapped at the grain boundary 8b is almost constant among the heat-sensing parts 8. Further, the particle sizes of the crystal grains 8a are uniformed to reduce the dispersion in the average particle size of the particle grain of each heat-sensing part 8. The heat-sensing part 8 is film-formed by a vacuum CVD method wherein a film-forming temperature is about 600-650 deg.C.  Thus, the dispersion in sensitivity among a plurality of heat-sensing parts is reduced to eliminate the need for providing a separate correcting means, resulting in a reduced cost.

Filed: 1987-08-26
Abstract: PURPOSE:To find a fire and to monitor the degree of contamination of air in a room by detecting the change of the quantity of light of infrared rays emitted from a light emitting part which are received by a light reception processing part after passing a monitor area. CONSTITUTION:Since the quantity of light of infrared rays received by a light reception processing part II is reduced according as the carbon dioxide concentration in a monitor area 7 is increased, the detection signal level of a pyroelectric infrared detector 3 is reduced according as this concentration is increased. Since only the variation of received infrared rays is detected in accordance with the characteristic of the pyroelectric infrared detector 3 and the differential output is obtained, this signal is amplified to a prescribed level by a signal amplification processing circuit 4, and thereafter, the processing output is obtained by peak holding or integration. The obtained processing output is compared with a reference level by a level discriminating circuit 5 because it is reduced in accordance with the carbon dioxide concentration in the monitor area 7, and an abnormality signal is outputted if it is lower than the reference level. Thus, smoke and flames are sensed and the degree of contamination of air due to existence of persons or the like is detected.
