Title: Semiconductor photo-detector
Inventor: YAMAMOTO YOSHIHISA
IPC: H01L31/10
Filed: 1978-11-27
Abstract: PURPOSE: To provide a planer construction APD (avalanche photo diode) small in the dark current and the junction capacity reducing the process by forming the pn- conjunction under the photo detecting surface in or in contact with a semiconductor material having a band gap smaller than the pn-junction around the surface.  
     CONSTITUTION: An epitaxial layer 10 of n-type InGaAsP or InP is made to frow on an n + -type InP substrate 9 and a mesa etching is conducted to remove all thereof but the central portion. Then, an n-type InP layer 11 is made to grow on the entire substrate including the central portion and a p-type region 3 is formed on the layer 11 by diffusion reaching the layer 10. Otherwise, the continuous epitaxial growth of the layer 11 may be done on the layer 10 and then, a partial etching is conducted to form a region 3 in an area including the layer 10. It also may be accepted that the layers 10 and 11 are further continuously grown with the front of the region 3 demarcated near the interface between the layers 10 and 11. This allows the breakdown voltage to be almost equal to that of the pn-junction with a curvature around the photo detecting surface reducing the diffusion process, making the device ideal for APD very small in the photo detecting diameter.

Title: Building material composed of phosphate cured body
Inventor: MOTOKI HIDEO
IPC: C04B28/34
Filed: 1988-06-13
Abstract: PURPOSE:To obtain a building material enhanced in fire resistance, surface hardness and weatherability by applying as the second layer, a slurry prepared by adding water to a powder mixture of magnesium oxide and ammonium phosphate to the single or both surfaces of the first layer composed of a heat insulating material. CONSTITUTION:As slurry prepared by adding water to a powder mixture of magnesium oxide and ammonium phosphate is applied to the first layer composed of a heat insulating material such as an org. material, for example, polyvinyl chloride foam or polyurethane foam or an inorg. material, for example, an asbestos pearlite panel or foamed glass. Whereupon, the slurry is infiltrated in the heat insulating material to be cured but, since liquid temp. is lowered by the endothermic reaction generated when the ammonium phosphate is dissolved in water and the reaction of ammonium phosphate with magnesium oxide is temporarily suppressed, a usable time can be secured. Since the reaction cured body of the slurry contains combined water, said cured body has fire resistance and, when the slurry is applied to the surface of the heat insulating material of the first layer to be reacted and cured, the cured body enhances the fire resistance of the first layer and also suppresses the temp. rise of the internal heat insulating material to make said layer hard to burn. As a result, a building material having functions such as fire resistance, heat insulating properties or the like is obtained.

Abstract: PROBLEM TO BE SOLVED: To induce ventilation inside a shoe to lessen the sweatiness of a foot and prevent athlete's foot developing by providing an inside sheet with a flat pump equipped with an induction valve, an exhaust valve and a helical compression spring, and by walking with such inside sheets in the shoes. SOLUTION: When a person walks in shoes, the shoe heel rises and develops a space between the sole and the heel bringing a helical spring 5 into action, with the result that the capacity of a flat pump 2 increases and air is inhaled by way of an induction valve 3. When the heel lands, the weight of the person pressed down the flat pump 2, and the air inside the flat pump is pushed out by way of an exhaust valve 4 and led toward the toe through an air duct 6. Therefore, the air inside the bottom of the shoes shifts and ventilation is performed. In this case, a vinyl sheet is used as material for an inside sheet 1, and an elastic, adhesive crude rubber sheet is used for the induction valve 3. A polyvinyl chloride tube is used as the exhaust valve 4 with one end of it squashed. A thin plate of stainless steel is shaped into a helix and used as a helical spring 5.
