Title: Fire detection method
Inventor: NAYA KAZUNARI
IPC: G01J5/60
Filed: 1992-09-04
Abstract: PURPOSE:To clearly distinguish fire from non-fire by calculating the temperature of a body to be detected based upon the relative ratio of intensity values of plural infrared-ray radiation bands including the intensity of infrared rays existing at least in the resonance radiation area of CO2. CONSTITUTION:Infrared rays radiated from a fire source or a similar heating source are periodically divided by a chopper and four respectively different wavelength bands are detected by four pyroelectric infrared sensors. These sensors include band pass filters capable of penetrating previously determined wavelength bands. Detected signals are aplified by an amplifier circuit and then converted into a digital signal by an A/D converter. A microprocessor applies period detection and filtering based upon the dividing period of the chopper to the digital signal to return the divided signals to a continuous signal sequence. The wavelength band of detecting infrared rays are set up so as to efficiently detect the radiation of the heating body. Then the relative ratio of intensity values of plural infrared-ray radiation bands including the intensity of infrared ray existing the resonance radiation area of CO2 is found out.

Abstract: PROBLEM TO BE SOLVED: To provide an optical photodetecting device mounted as a CMOS device which by for less expensive than a bipolar photodetecting device, which a CMOS processing circuit for amplifying the output of a photodiode and a photodiode preferred to be mounted on the same semiconductor substrate. SOLUTION: An antireflection coating comprising a composite layer of a silicon nitride 44 and a silicon dioxide 42 is formed over the entire photosensitized region of a photodetector, for minimum reflected amount. The composite layer comprises a silicon nitride layer and an adjacent dielectric layer. The antireflection coating is formed at PN junction with a photodiode and in a CMOS process for assembly/manufacture of a CMOS device for amplifying a photodetector signal, with a polysilicon gate layer used as an etching stop here. P+ or N+ material at P-N junction of a photodiode is a distributed one, and two parts in the region are separated from each other by a distance in the range of Xd-2Xd, with the Xd being a single-sided joint void width, which shortens the distance that a carrier advances for raising electric field and band width.

The output of a D/A converting circuit DA is outputted to all signal voltage holding circuits MOi ((i) is 1 - N), but when the data D1 is sampled, only the analog switch ASWM of a signal voltage holding circuit MO1 corresponding to the first source line O1 is energized by the selecting pulse Tm1, so that an external voltage V3 is applied only on the capacitor CM of the signal voltage holding circuit MO1. Therefore, the load of the external voltage source is extremely reduced.

Abstract: PURPOSE:To attain imperfect coupling and to lessen the dependency of a branching ratio on wavelengths by integrally heating and fusing members for arraying the optical fibers held in parallel and filling the spacing therebetween, then stretching these members under heating, thereby producing tapered parts and imparting asymmetry to the waveguide structure of the two cores at the time of producing the light coupling part. CONSTITUTION:The protective coatings of two pieces of the optical fibers 1, 2 are partly removed and the fibers are held parallel. The parts where the coatings are removed are pinched by the arraying members 3 made of dielectrics having nearly the same refractive index as the refractive index of the clads and are tentatively fastened to prevent the disengagement of this combination. The arraying members 3 made of the dielectrics and two pieces of the optical fibers 1, 2 are integrally heated and fused to form the fused part and to integrate the arraying members 3 made of the dielectrics and the clads 4, 5 of two pieces of the optical fibers 1, 2. The outside shape of the arraying members 3 made of the dielectrics and the optical fibers taken therein are offcentered.
