Title: Semiconductor photo detector
Inventor: YASUDA KAZUTO
IPC: H01L31/109
Filed: 1982-06-08
Abstract: PURPOSE:To make the most part of holes excited in an absorption layer which is influenced particularly greatly by a hetero epitaxial junction flow into a multiplication layer at a high speed and thus contrive to improve the response speed of a photo detector by a method wherein the energy bands are positioned at three layers. CONSTITUTION:N-In0.53Ga0.47As 12, N-In1-xGaxAsyP1-y 13 (x=y/2.197, y=0.25- 0.7), and N-InP 14 are superposed on an N<+>-InP substrate 11, and a P<+> layer 15 is formed by Cd implantation into the layer 14, and a P type guard ring 16 by Be introduction, an insulation film 17 is selectively provided, and then fixed electrodes 18 and 19 are added. By this constitution, the energy band width of the layer 13 has the valve medium between that of the photo absorption layer 12 and that of the multiplication layer 14 and then selects the thickness of the layer 13, accordingly makes the minimum energy level E2 of the valence band of the photo absorption layer 12 equal to the maximum energy level E1 of the valence band of the multiplication layer 14 or higher than it in the operating state of the device. Thereby, carriers becomes easy to pass through the hetero- epitaxial junction, and therefore the response speed can be improved.

IPC: F16K31/02
Filed: 1980-07-18
Abstract: PURPOSE: To obtain sure control for a valve by a small electric power in an electric switch valve used in a refrigerating cycle of refrigerant by adopting a form-memorizing alloy for a drive element of the valve for obtaining a small-sized switch valve.  
     CONSTITUTION: A heater 10 is wound round a plate-shaped valve drive element 9 made of Ni-Ti alloy, and an operation rod 14 is inserted between the element 9 and a diaphragm 11. Generally, in a maltensite transformation phase, a form- memorizing alloy is easily displaced by an external force. This valve drive element 9 is transformed by the elasticity of a spring 13 to be convexed in the center and a valve body 12 is separated from an opening part 5 for conducting fluid from the first passage 2 to the second passage 3. Meanwhile, when the heater 10 is electrified to heat this alloy over a fixed temperature, the maltenside transformation phase is extinguished to obtain the original metal phase of a high elesticity, and the valve drive element 9 is returned into a flat state before transformation. As it is made flat, it pushes the valve body 12 downward against the spring 13, and closes the opening part 5 for intercepting the flow of the fluid.

Title: Photosensor system
Inventor: YAMADA HIROYASU
IPC: H01L27/146
Filed: 1993-03-31
Abstract: PURPOSE:To provide a photosensor system which provides high sensitivity optical characteristics and simplifies a manufacturing process. CONSTITUTION:A photosensor system 1 forms an insulation substrate 6 having a specified film thickness on a single crystal silicon substrate 5. A TFT photosensor 2, which uses amorphous silicon in double gate structure, is formed on the insulation substrate 6. As the difference of drain current between light emission time and non-light emission time is markedly increased, it is possible to provide high sensibility optical characteristics. It is also possible to form various kinds of circuit elements, such as an n-MOSFET 4 which drives and controls the photosensor 2 in a simple process on a p-type single crystal silicon substrate 5 by forming an n<+> high concentration impurity diffusion layer. The photosensor 2 and the n-MOSFET 4 are formed one upon another, thereby reducing the size of the photosensor system and enhancing the higher density of picture elements.

Abstract: PURPOSE: To enable the use of a heat exchanger as an evaporator, by a method wherein an air-liquid distribution of a coolant in tilting tubes is brought into such a state as prevents from reduction in a heat exchange efficiency.  
     CONSTITUTION: On a coolant inlet port side, an inlet hole 11 of a coolant, flowing into the first stage tube 1 1  from an inlet header, is provided at only an air inlet port side (a). A fluid path of a spacer block 4 1  being laid between the first stage tube 1 1  and the second stage tube 1 2  is partitioned into a portion 41a, facing and connecting to the inlet hole 11, and other portion 41b, and a fluid path 42 of a spacer block 4 2  being laid between the second stage tube 1 2  and the third stage tube 1 3  runs from the air inlet port side (a) to an outlet port side b without any partition. This enables the coolant flowing in each tube to flow such that unevaporated liquid coolant flows on the air inlet port side (a) and a gas coolant flows on the outlet port side b. Thereby the liquid coolant is distributed in proportion with difference in temperature between air and coolant, which results in improving a heat  exchange efficiency.
