Title: Temperature sensor
Inventor: NAKAZAWA NOBUO
IPC: H05B3/14
Filed: 1987-05-26
Abstract: PURPOSE:To make it possible to measure the temperature in a high temperature atmosphere readily and stably, by receiving the temperature of the atmosPhere with an outer coating for detecting the temperature, receiving radiation energy emitted from the inner surface of the outer coating with an optical fiber, which is provided therein, and guiding the energy into an infrared-ray sensor. CONSTITUTION:The temperature of an optical fiber 1 is kept at about 500 deg.C or less with a cooling pipe 8a comprising copper and the like and a cooling device 8b, which cools the end part of the pipe 8a. Thus deterioration is prevented. The end surface of the fiber 1 is set at a position where a tip part can be monitored (an effective field of view 7) through a space 4 at the inner surface of a high temperature part 5 of an outer coating 2. Infrared rays, which are emitted from the inner surface of the tip of the outer coating 2, are received and transmitted to an infrared-ray sensor 3, which is provided at the outside. The outer coating 2 is formed with ceramics and the like such as sintered zirconia, which can stand about 2,000 deg.C. The space 4 is filled with inactive gas or made to be a vacuum state in order to prevent the deterioration of the inner surface of the outer coating 2. In this constitution, an infrared-ray radiation thermometer, which can measure the temperature of an atmosphere at about 1,000-3,000 deg.C readily and stably, can be constituted.

Title: Pattern forming
Inventor: YONEDA YASUHIRO
IPC: H01L21/302
Filed: 1978-10-16
Abstract: PURPOSE: To obtain resists of excellent resolution characteristics, by heat treating a copolymer of methyl methacrylate and methacrylic and/or acrylic acid at a temperature below the principal chain cutting temperature and then dissolving it in a solvent.  
     CONSTITUTION: A copolymer of methyl mathacrylate, 90mol%, and methacrylic acid, 10mol%, is given heat treatment in N 2  gas at 200°C for 15min. Next, this is dissolved in N, N-dimethylformamide. Further, as an auxiliary agent to avoid coating unevenness, 2-ethosyethylacetate is mixed with it by the same amount of formamide. Resist solution obtained in this way is coated on a semiconductor wafer and is left in N 2  gas solution for 24 hours. After this, the substance is sintered preliminarily in N 2  gas at 160°C for 50min. The result shows the lowering in the degree of dissolution required for forming a clear pattern. Consequently, the resultant resist has good resolution characteristics and permits easy application.

Title: Manufacture of semiconductor integrate circuit
Inventor: SADAKATA TOSHIMASA
IPC: H01L27/06
Filed: 1989-05-19
Abstract: PURPOSE:To improve a semiconductor integrated circuit in degree of integration by a method wherein the contact region of a base region is formed self-aligned with one end of an introduction hole provided onto the base region. CONSTITUTION:A contact region 28 of a base region 27 is self-aligned with a thick silicon oxide film 40 of the peripheral end of an introduction hole 42 of the base region 27 by making an opening located on the left side of a resist 45 slightly large. Therefore, the contact region 28 can be prevented from deviating positionally leftward. Consequently, a margin required for the deviation concerned can be lessened around the base region 27, and the base region 27 can be reduced in margin required due to the deviation of the contact region 28. By this setup, a cell can be lessened in size, and moreover an integrated circuit of this design can be reduced in occupying area by the reduction of all cells in area, so that a chip can be reduced in size and improved in degree of integration.

Title: Ozone catalytic reaction tank
Inventor: ISHIDA KOJI
IPC: C02F1/50
Filed: 1993-05-31
Abstract: PURPOSE:To increase an ozone dissolving rate, to prevent complete mixing in a reaction tank, to hardly lower the dissolved ozone concn. and to increase the reaction rate between a material to be treated and ozone by mixing water to be treated and gas while keeping a large concn. difference between ozone in water and ozone in gas. CONSTITUTION:A water to be treated and an ozonized gas are mixed in an ozone catalytic reaction tank 15, and a device 16 for dissolving ozone in water is installed. A reaction tank 17, in which water supplied from the device 16 flows downward in a definite direction and the matter to be treated in water is oxidized by the dissolved ozone, is furnished on the downstream side of the device 16. Consequently, the ozone dissolving rate is increased because the water and gas are mixed while keeping a large concn. difference between ozone in water and ozone in gas. Meanwhile, since the water and gas are not completely mixed in the reaction tank, the ozone concn. is hardly lowered, and the reaction rate between the matter to be treated and ozone is increased.

Title: Grid for lead-acid battery
Inventor: OMAE TAKAO
IPC: H01M4/74
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To suppress deformation of a grid and lengthen the life by specifying the ratio of the area of the region where the shape of a part surrounded by frames formed by development becomes a triangle to the area of a grid development part. SOLUTION: Expanded grid structure having a grid development part (net part) 5 formed by developing a lead sheet in the lower part of an upper frame 4 is formed. In the case that the shape surrounded by frames formed by development is a rhombus, the rhombus easily deforms in the longitudinal direction or the lateral direction when stress is applied, but in the case that the shape is a triangle, the deformation in the longitudinal direction or the lateral direction is structurally suppressed. The relation of the area A of the region of the part 6 where the shape of the part surrounded by frames formed by development becomes a triangle to the area S of the whole grid development part 5 is specified to 0.1<A/S<=1.0.  The deformation of an electrode plate is suppressed, battery performance is enhanced, and in spite of the use of the expanded grid, a battery having a long life can be obtained.

Abstract: PURPOSE: To eliminate the need for gathering of copying paper after copying by feeding the film until the final frame mark of the number of matters to be copied is detected then reverse feeding the film frame by frame.  
     CONSTITUTION: FF 1 , FF 2  are reset by the copying command signal, then a flim is moved forward by way of a film forward driving unit 150. When the matter mark detection signal of one matter before a matter mark detector 101 is applied to an OR gate G6 and an AND gate Gl, the film stops and after a specified time delay, the film is fed backward by way of a film backward feed unit 151. Then, when the final frame mark of the requied number of matters is detected with a frame mark detector 100, an AND gate G2 opens and in the similar manner the film stops and a copying circuit 154 is started by the gate output of the gate G2. At the same time FF 1  is set and the gate 4 is opened, then copying of each frame through backward travel of the film is accomplished. Hence, the copying sheets of respective pages are subsequently stacked on the discharge tray with the final page in the lowermost  position, thus easy copying without requiring gathering, etc. may be accomplished
