Title: Surface type optical switch
Inventor: KASAHARA KENICHI
IPC: H01L31/14
Filed: 1993-06-11
Abstract: PURPOSE:To provide the surface type optical switch which enables two-dimensional integration, is compact, operates on a low voltage and enables the selection of arbitrary wavelength by voltage by inserting a semiconductor structural body having a p-n junction between mutilayered semiconductor film mirrors. CONSTITUTION:This surface type optical switch is a semiconductor structural body on which the multilayered semiconductor film reflection mirror DBR1201, intermediate layer and DBR2207 are formed on a GaAs substrate 200. The dip of the reflectivity observed near the center of reflectivity is shifted about 500Angstrom  by a change in the thickness of the intermediate layer from 0.9lambda to 1.1lambda. The position of the dip is further moved by using the characteristics of such structural body to vary the wavelength of transmitted light by applying a reverse bias voltage thereto. The structure to apply the voltage to the intermediate layer as the p-n junction is adopted in order to vary the wavelength of the transmitted light by the voltage. As a result, the refractive index is changed and the effective thickness of the intermediate layer is changed and, therefore, the wavelength of the transmitted light is varied. The height of the element in this structure suffices with <=lambda and, therefore, the element can be miniaturized. The operating voltage can be made small as several Volts in principle.

Title: Electrophotographic sensitive body
Inventor: SAKAI KIYOSHI
IPC: G03G5/04
Filed: 1985-06-28
Abstract: PURPOSE:To obtain a laminate type electrophotographic sensitive body having very high sensitivity by using a specified polycyclic quinone pigment as a charge generating material in a charge generating layer and a specified hydrazone compound in a charge transferring layer. CONSTITUTION:A charge generating layer is made of a layer contg. a polycyclic quinone pigment represented by formula I and a charge transferring layer is made of a layer contg. a hydrazone compound represented by formula II. The charge generating layer contains the charge generating material to the utmost limit so as to obtain satisfactory absorbance, and the layer is preferably formed as a thin film of 0.01-1mum thickness so as to efficiently implant generated charge carriers into the charge transferring layer. The charge generating layer can be formed by mixing the pigment represented by the formula I with a proper binder, adding a charge transferring material as required and coating the mixture on a substrate. Since there is a limit in the capacity of the charge transferring layer to transfer charge carriers, the thickness of the layer can not be made larger than the necessary thickness. The preferred thickness is 8-20mum.

Title: Heat collection control device for solar heat collecting hot-water supplying system
Inventor: NAMIKAWA HIROAKI
IPC: F24S90/00
Filed: 1982-08-11
Abstract: PURPOSE:To prevent the operation of a circulation pump as a heat collecting circulation pump at night in spite of the absence of the sunshine by a method wherein the starting and stopping control of the circulation pump is cut in the morning and evening by discriminating day and night based on the amount of the sunshine as well as a temperature difference between the outlet of a heat collector and a heat accumulating tank while the starting and stopping control of the circulation pump in a day time is effected by both conditions of the amount of the sunshine and the temperature difference. CONSTITUTION:The timer contact of a day and night timer TA is put OFF in the early morning and evening, therefore, the circulation pump P is not operated. When it becomes day time, the timer contact of the timer TA is put ON, therefore, the starting and stopping control of the circulation pump P is effected by utilizing both sensors H, M of the amount of sunshine and the temperature difference. When the sunshining time is short, the timer is not operated and the circulation pump is left stopping. On the other hand, when the temperature difference between the outlet of the heat collector 4 and the heat accumulating tank 5 is less than 4 deg.C, the output of the temperature difference sensor M is made OFF and the circulation pump P is stopped. On the contrary, when the temperature difference is existing, the circulation pump P is operated and functions as the heat collecting pump as far as the sunshine is existing while it is stopped when the sunshine is terminating.

Title: Solar heat storing system
Inventor: SHIGIYAMA KEIGOROU
IPC: F24S90/00
Filed: 1978-11-14
Abstract: PURPOSE: To accumulate hot water efficiently into a heat storage tank by opening or closing a check valve on difference in the temperature between the heat collecting box and the circulating fluid in the heat storage tank.  
     CONSTITUTION: When sun light comes upon the heat collecting box 1, heated with a black heat absorbing plate, water goes higher in the temperature than that of water in the heat storage tank. A check valve opens and the hot water in the heat collecting box 1 enaters the heat storage tank 5. Then, it moves down through an introduction pipe 7 and diffuses in the tank 5 in such a manner as to spring up slightly below the center of the tank 5. The hot water is stored gradually from the upper portion floating above from slightly below the center. Even when the circulation is halted, in time, a low temperature is gradually transmitted to the pipe 7 from a heat storing plate 8 extended to the lower low temperature section to lower the temperature of the water in the pipe 7. This causes a sufficient difference in the temperature between the heat collecting box and the heat storage tank to open the valve 11. With repetition of this process, the hot water is circulated intermittently until it is stored down to the lower section in the heat storage tank 5.
