Title: Photosensitive and heat-sensitive composition
Inventor: KUNIKANE MAKOTO
IPC: G03C5/56
Filed: 1980-02-28
Abstract: PURPOSE:To enhance the fixing and coloring sensitivities of a composition by adding a photoreducing agent, a hydrogen donor, the salt of a dye leuco body and a strong acid, and a photooxidizing agent which acts when irradiated with ultraviolet rays together with a Co (III) ammine or amine complex contg. I as the ligand of Co. CONSTITUTION:A fixing component generating a base such as NH3 or amine and a coloring component are mixed and formed into a layer. Fixing and coloring layers may be formed separately. The fixing component contains a Co (III) ammine or amine complex contg. one or more I atoms as the ligand of Co, a photoreducing agent which forms a reducing agent when irradiated with visibile light in the presence of a hydrogen donor and the hydrogen donor as a reducing agent capable of forming a redox couple together with the photoreducing agent. The coloring component contains the salt of a dye leuco body and a strong acid and a photooxidizing agent which allows the leuco body to color by oxidation and is reduced to lose the oxidizing power when irradiated with ultraviolet rays. Using the esulting photosensitive and heatsensitive composition both positive and negative images are obtd. by selecting the irradiation order of visible light and ultraviolet light.

Title: Image reader
Inventor: SAWAMURA AKIRA
IPC: H04N1/401
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To fast perform shading correction by a circuit that has a small scale by correcting the intensity of a signal of a read image through subtraction by a specific subtracter and multiplication by a specific multiplier in each pixel. SOLUTION: A pseudo-division circuit 21 calculates a division result K/(IW-IB) and operates when a standard image is read. When an image that becomes an object of shading correction is read, output signals of a line sensor are sequentially given to a substrater 24 from an AD converter. The minimum intensity IB stored in a memory 22 is sequentially given to the substrater 24 and the substrater 24 subtracts the IB form signal intensity IO before correction. The output is given to a multiplier 25, also, the K/(IW-IB) stored in a memory 23 is sequentially given to the multiplier 25 and the multiplier 25 multiplies a subtraction result given from the subtracter 24 by it, sequentially outputs the results and gives them to a gamma correction circuit 28. Here, the IW is the maximum intensity of a standard image signal, the IB is the minimum intensity and the K is a constant.

Title: Molding method of double layer molded article
Inventor: KOJIMA YUTAKA
IPC: B29C45/26
Filed: 1979-03-06
Abstract: PURPOSE: To obtain double layer molded article without developing burr by a method wherein the exposed projection outer surface of a molding is compressed by the secondary mold for compression molding the outer surface of the projection.  
     CONSTITUTION: For double layer molding producing the casing such as a plug socket, the inner shell is molded primarily by thermosettisynthetic resin, working the secondary molding to enclose the outer shell 2 of thermoplastic synthetic resin before hardening the inner shell 1, the outer face of the external projection 3 of the inner shell 1 is compressed by the secondary mold 4, allowing to mold the outer shell 2 under the condition compressing the external face of he projection 3 for developing double layer molded article. Since the molded article is formed by the secondary molding the outer shell immediately after the primary molding of the inner shell, cost reduction can be attained by reducing the process in comparing with the conventional method. Further, since the external projection surface of the inner shell is compressed by the secondary mold for forming the external shell, this  enables the resin to prevent from entering the space between the projection external  face and the secondary mold, which produces a fine double layer molded article  without developing the burr.

Abstract: PURPOSE:To improve response, electrostatic force and heat transfer efficiency by partially arranging and bonding a conductive-resin material board consisting of a conductive rubber, plastics, etc., onto a surface electrostatically attracting a wafer at intervals in a plane manner. CONSTITUTION:Conductive rubber boards 13 which have been disposed under a high molecular film 12 are arranged onto the high molecular film 12 at intervals, that is, partially on viewing in a plane manner. Negative electric charges A31 are stored only between the conductive rubber boards 13 in a wafer 11. Negative electric charges B32 are stored in the conductive rubber boards 13. Electrostatic force working on the wafer 11 is represented by the sum of charge Coulomb's force between negative electric charges A31 and filmsurface charges 28 and that between negative electric charges A31 and positive electric charges 16. Electrostatic capacity C between the wafer 11 and the high molecular film 12 surface inversely proportional to the thickness of a space 30 can be reduced largely, the charge and discharge time of filmsurface charges 28 are also shortened in proportion to the lowering of electrostatic capacity C, and electrostatic force by filmsurface charges 28 inversely proportional to the square of the thickness of the space 30 is minimized simultaneously. Accordingly, electrostatic force having high response based on positive electric charges 16 stored in a lower electrode 35 is the principal ingredient as electrostatic force working to the wafer 11.

IPC: G21D1/00
Filed: 1978-03-10
Abstract: PURPOSE: To suppress the increase in the concentration of radioactive corrosion products and prevent them from flowing out of the core of a reactor and diffusion to an entire cooling system, by injecting hydrogen into cooling water from the time just before the stoppage of operation of a nuelar unclear power plant to the time just after the re-starting of operation of the plant.  
     CONSTITUTION: The injection of the hydrogen into the cooling water from the discharge side of a recirculating pump 3 of a cooling water recirculating loop 3 is started just before the operation of the nuclear power plant is stopped. The hydrogen concentration of the cooling water in the reactor is maintained at 22 exp(0.013t)cm 3 N.T.P/kgH 2 O or more. The corrosion products, the quantity of which increases around the stoppage and re-starting of operation of the nuclear power plant, are reduced by the hydrogen so that a metal is separated on the reactor core material and the corrosion products are suppressed from being dissolved in the cooling water. New corrosion is thus decreased.
