摘要： A light scattering type smoke sensor comprising a holder (5) with openings (9, 10) embedded with light emitting part (6) and light detecting part (7) respectively, which do not protrude into the smoke detection chamber (4). The optical axis (14) of light emitting part (6) intersects at a predetermined first angle alpha in the horizontal direction with the optical axis (15) of the light detecting part (7) at a predetermined second angle beta in the vertical direction. The optical axis (14) of the light emitting part (6) and optical axis (15) of the light detecting part (7) further comprise a configuration angle delta in the range of 90 SIMILAR 120 degrees used as the supplementary angle for the scattering angle &thetas;. Accordingly, the smoke detection part is further constituted in a thin-shaped light scattering smoke sensor which enables the setup of a scattering angle with no directivity in the smoke influx to the smoke detection chamber (4).

摘要： [Problem] To provide a scattered light-type smoke detection apparatus, wherein internal scattered light in a smoke detection space is suppressed and an S/N ratio is improved. [Solution] A scattered light-type smoke detection apparatus (1) is provided with: a smoke detection space (20), which is provided in a light-shielded region that is shielded from light from the outside, and has smoke particles flow therein from the outside; a light emitter (30) which emits detection light toward the smoke detection space (20); and a light receiver (40), which receives scattered light generated when the detection light that has been emitted from the light emitter (30) is scattered by means of the smoke particles that have flowed into the smoke detection space (20). The scattered light-type smoke detection apparatus is characterized in being provided with an internal scattered light suppressing means, which suppresses the internal scattered light in the light-shielded region by guiding, while transmitting, a part of or the whole detection light to a predetermined region or to the outside of the light-shielded region, said detection light having been emitted from the light emitter (30), and passed through the smoke detection space (20).

摘要： A fire detection device comprises a detection element to convert the infrared ray energy into the electric signal, a first extracting unit to extract the signal of a first prescribed frequency range including the flicker frequency of a fire from the output signal of the detection element, a second extracting unit to extract the signal of a second prescribed frequency range including no flicker frequency of a fire but including the frequency on the higher frequency side than that of the first prescribed frequency range from the output signal of the detection element, and a judging unit to judge a fire based on the output signal of the first extracting unit and the output signal of the second extracting unit. The fire detection device is capable of surely discriminating and detecting the flame from other infrared ray energy generation source. A band pass filter or the like need not be increased in number, and the increase in the product price can be prevented. In particular, the flame detection device is capable of rapidly judging a fire, and suitable for practical applications.
