IPC: G01J1/02
Filed: 1982-08-18
Abstract: PURPOSE:To obtain a compact, highly sensitive infrared ray detecting element, by supporting only end parts of a pyroelectric material, gouging the central part of the material, suspending the material, forming a reflecting body at the gouged part, and utilizing infrared energy that is inputted to both surfaces of the detecting element. CONSTITUTION:A pyroelectric material 21, to both surface of which infrared absorbing electrodes are attached, is bonded to a supporting body 22 at the end parts as shown by the Figure. Said supporting body is made of an Si substrate. Incident infrared ray 34 is directly inputted to the side of a surface electrode 32 of the element 21 and also inputted to a back surface absorbing electrode 33 of the element 21 after the reflection from a reflecting surface 45 of the supporting body. Since the infrared ray inputted to the back surface is added to the infrared ray inputted to the surface absorbing electrode 32, the effective incident infrared energy becomes large. This is very advantageous from the viewpoints of the thermal capacity and the electric capacity of the element in comparison with a pyroelectric element having the equivalent area, and the output becomes large. Si is selected for the supporting body 22 for ease of machining. But the material is not limited to the Si, if it can be machined so as to produced the same effect. When the reflecting surface 45 is formed in a spherical, elliptical, parabolic shapes and the like, light converging efficiency is further increased, and higher sensitivity is obtained.

IPC: F24J2/46
Filed: 1982-08-20
Abstract: PURPOSE:To form the device in a structure for the difficulty of snow deposit and facilitate snow removing by a method wherein a clear film is so provided by extension, in the uprightly provided front surface of a power generator which receives solar rays and charges as to cover the photo receiving and power generation surface. CONSTITUTION:The plastic film 3 which transmits the solar ray having flexibility and weather resistance is fixed at the upper end 25 of a roof part; the under part is supported by deflection toward the horizontal direction of a base frame 22 by means of a rotary roller 31, and then extended by energization by means of a spring 32 of appropriate turns. Even when it begins to snow resulting in snow deposit on the roof part 24, the power generator 1 does not receive the influence by this snow fall because of being fixed inside roof enclosure of the frame, but the front surface is guarded by the vertical plastic film 3 in the case of snowstorm, etc. In other words, snow becomes difficult to deposit, because the surface of the film 3 is vertical, flexible, and is elastically extended, and due to its evenness and snow deposit difficulty, even if snow deposits thereon, the snow drops by wave motion and vibration due to the wind. The effect thereof is enhanced by the roller 31 and the spring 32, and accordingly the function is maintained by adapting itself to the expansion and contraction of the film 3.
