摘要： PURPOSE: To eliminate the need for an optical trap mechanism, and to narrow down a measurement space and to reduce the size by reflecting a radiant light beam from a projection several times by a right and a left wall through a front and a rear wall and preventing the reflected light from striking on a photodetector directly.
CONSTITUTION: The radiant light from the projector 1 is reflected at the left side of the front wall 6, reflected by the left wall 4 and right and left walls 5 and 4, and further reflected by a ceiling wall 9, walls 5 and 4, and rear wall 7 to strike the external wall of the photodetector 2. Therefore, the radiant light from the projector 1 becomes weak light through optical trapping operation while reflected by the walls 4 and 5 several times. If smoke enters a darkroom owing to fire occurrence, on the other hand, its scattered light illuminates the photodetecting element of the photodetector 2 to generates an output of fire annunciation. The output of the photodetexting element when the smoke enters the room to specific thickness where fire occurrence is judged is denoted S and an output in a normal state is denoted as N; and when the angle θ between the front and rear walls 6 and 7 is ≤140° or ≥210°, a sufficient S/N is obtained.

摘要翻译：目的：为了消除对光学捕获机构的需要，并且通过左右壁和前壁和后壁将来自投影的辐射光束几次反射来缩小测量空间并缩小尺寸，并且防止反射光直接撞在光电探测器上。构成：来自投影仪1的辐射光在前壁6的左侧反射，被左壁4和左右壁5和4反射，并被顶壁9，壁5和4进一步反射，和后壁7撞击光电检测器2的外壁。因此，来自投影仪1的辐射光几乎通过壁4和5反射而通过光学捕获操作变成弱光。另一方面，如果烟雾由于发生火灾而进入暗室，则其散射光照射光电检测器2的光电检测元件以产生火灾通知的输出。当烟雾进入室内时光电检测元件的输出被判定为发生火灾的特定厚度，S表示正常状态下的输出，并且当前壁6和后壁7之间的角度θ<140度时。或> = 210度，获得足够的S / N。

摘要： PURPOSE: To dispense with the arrangement of a light trapping mechanism by preventing the light emitted from a light emitter from being directly incident to the light receiving element of a light receiver, by allowing a dark room itself to have light trapping function.
CONSTITUTION: The light from a light emitter 1 is reflected from the left side of a front wall 6 to be impinged to a left side wall 4 and reflected from right and left side walls 5, 4 and further reflected from a ceiling wall 9, the right side wall 5, the left side wall 4 and the left side of a rear wall 7 to be impinged to the outer wall of a light receiver 2 and attenuated to act as a light trap to be converted to extremely weak light. Now, when smoke is penetrated into a dark room by the generation of a fire, the scattered light thereof irradiates the light receiving element of the light receiver 2 to generate output for informing the generation of the fire.

摘要翻译：目的：通过防止从光发射器发出的光直接入射到光接收器的光接收元件，通过允许暗室自身具有光捕获功能，省略了光捕获机构的布置。构成：来自发光体1的光从前壁6的左侧反射成与左侧壁4碰撞并从左右侧壁5反射并进一步从天花板壁9反射，右侧壁5，左侧壁4和后壁7的左侧将被照射到光接收器2的外壁上并被衰减以用作光阱以转换为极弱的光。现在，当烟雾通过产生火焰而进入黑暗的房间时，其散射的光照射到光接收器2的光接收元件，以产生用于通知火的产生的输出。

摘要： PURPOSE:To detect easily a special gas with high accuracy by treating a mixture composed of the oxides of tin, platinum and antimony in a gaseous silane atmosphere and using such mixture for a detecting element to detect the special gas which has an easy tendency to spontaneous ignition in air. CONSTITUTION:The mixture composed of the oxides of tin, platinum and antimony is manufactured, for example, in the following manner. The mixture composed of stannic oxide, chloroplatinic acid and antimony trioxide is first calcined at about 600-850 deg.C in the atm. The compsn. ratio is preferably made antimony/ tin=1-8mol%, platinum/tin=1-8mol%. The mixture composed of the resulting oxides is treated at about 200-400 deg.C in an atmosphere contg. 25-400ppm gaseous silane, for example, monosilane. The mixture is further subjected to an aging treatment and is made into a semiconductor consisting of the mixture composed of the metallic oxides. Such semiconductor is used for the detecting element. The detection of monosilane, dichlorosilane, etc. having the easy tendency to spontaneous ignition in air with high sensitivity by such detecting element is thus made possible.

摘要： PURPOSE:To simplify the constitution of a circuit by providing an alarming means repeating low and high heating of a detecting element with a means for sending an disconnection signal through a power supply line at the detection of disconnection of a heating means or an element and inverting the polarity of the power supply. CONSTITUTION:When switches S1, S2 are turned to a contact (a) and a heating control circuit 10 is actuated at a normal time, a pulse a having prescribed time interval is generated, a switch 10S is turned on synchronously with the pulse, a heater HE is heated through the power supply lines L1, L2, and gas is adsorbed to a gas detecting element GS to detect gas leakage by a gas leakage detecting circuit 60. In case of the detection of disconnection, the switches S1, S2 are turned to a contact (b), the polarity of the lines L1, L2 are inverted and the disconnection of the heater HE and the element GS is detected by a disconnection detecting circuit 20a for the heating means and a disconnection detecting circuit 20b for the gas detecting element respectively. When the disconnection is detected, a disconnection signal sending circuit 30 shorts the lines L1, L2, a disconnection detecting circuit 40 in a receiver R detects the disconnection and a disconnection display circuit 50 displays the disconnection.

摘要： PURPOSE:To detect fire without influence of temperature by forming spaces on a pair of glass windows in a sampling part guiding air from a monitoring area of a thermostatic chamber or the like by a suction fan and flowing back the air and setting up light projecting and receiving parts in the spaces. CONSTITUTION:Air in the thermostatic chamber 7 is sucked by the suction fan 42, flows from an inlet port 51 into a smoke room 21 through a pipe P1 then flows back to the thermostatic chamber 7 through a vent hole 22, a fan room 23, discharge port 52 and a pipe P2. A pair of glass windows 26, 27 are formed on the smoke room 21 and the light projecting part 31 and the photodetecting part 32 form a dimming type smoke detecting part 3 with the spaces A to be regarded as heat insulating layers. When the detected output from a photoelectric element 35 is reduced less than a prescribed value by smoke, a discrimination circuit is actuated and the generation of fire in the thermostatic chamber 7 is informed.
