Title: Assembling method for sodium-sulphur battery
Inventor: KATO SATORU
IPC: H01M10/39
Filed: 1988-11-11
Abstract: PURPOSE:To enhance the junction strength of an insulation ring to an anode container and a cathode container, by releasing gas from a furnace to vacuumize the inside of the furnace when the insulating ring is thermally pressurized and welded to the anode container and to the cathode container, then substituting inert gas for the gas released, and thereafter directly spraying the inert gas onto the thermal-pressure welding portion of an intermediate junction body. CONSTITUTION:Gas is released from a furnace 10 to vacuumize the inside of the furnace 10 at room temperature, and thereafter inert gas such as nitrogen gas is substituted for the gas released. The furnace 10 is next heated inside from room temperature to about 600 deg.C, so that oxygen gas that has been adsorbed to the insulation ring 2 of components to be welded and/or to the inside of the furnace 10 is released. This oxygen gas is heated and sprayed onto the thermal pressure welding portion of the insulation ring 2 by means of a special spraying nozzle 14 for nitrogen gas so as to protect the thermal pressure welding portion from the oxygen gas. Intermediate junction plates 5, 6 are thus preventing from being oxidized at high temperatures, and also the purity of the inert gas in the furnace 10 is restrained from deteriorating, and therefore the junction strength of the insulation ring 2 to an anode container 1 and to a cathode container 3 can be enhanced.

Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To enhance the bonding strength of a metal part and a molded article without exerting adverse effect on a molding cycle in a method for injection- molding a metal composite molded article and an injection mold used in this method. SOLUTION: A heat insulating layer 24 is formed to the surface 23 of a cavity 21 on a side where a metal part 2 is positioned to prevent the heat of a resin 30 from escaping to a movable mold 22 wherein the metal part 2 is positioned through the metal part at a time of the filling of the cavity with the resin 30. By this constitution, the melt temp. of the adhesive material layer 7 formed to the metal part 2 is kept to enhance the bonding strength of the metal part 2 and the resin 30 (molded article). Since no time is taken in the melting of the adhesive material layer 7, a molding cycle can be shortened.

Filed: 1988-11-14
Abstract: PURPOSE:To obtain the information on contamination, surface chemical reaction and associated damages and to improve the safety and reliability of a process and a system by measuring the influence of synchrotron radiation light on a sample within the same vacuum. CONSTITUTION:Beryllium foil 13 prepd. in a sample preparing chamber 2 is sealed into an evaluating chamber 1 and is supported by a sample holder 8. The sample is positioned in X-Y directions by a sample manipulator 9. Auger electron spectroscopic spectra are recorded by a cylindrical mirror type energy analyzer 11 in the state of not irradiating the synchrotron radiation light to the foil 13. The sample is then irradiated with the scanning beam of the synchrotron radiation light over a long period of time continuously or at intervals of several minutes and the auger electron spectroscopic spectra are recorded by the analyzer 11. The growth of the crystal layer on the beryllium surface is decided by comparison of the unirradiated state and the irradiated state of the sample. The judgement relating to the damages is, therefore, executed by evaluating the synchrotron radiation light of the beryllium.

Abstract: PURPOSE: To eliminate uncertainty due to the nonuniformity of a film and to measure the thickness of the film accurately by measuring the distance from the surface of the film to a measurement head with three measurement heads arranged on both surfaces of the film and calculating the thickness of the film from the result. CONSTITUTION: Distance between measurement heads 4 and 11 is measured by an optical detector. A light source 12 for emitting a narrow luminous flux is arranged at the measurement head 11, the light source 12 emits light with a wavelength for hitting against a surface 3 of the measurement head 4 through a film 5, and the image of light point is formed on the position-sensing surface of a light receiver 13. In this case, for example, infrared ray radiation can be considered. Then, a signal with a level that is proportional to the distance between the measurement heads 4 and 11 can be obtained from the light receiver 13. Further, a signal is obtained also by a light source 6 and a light receiver 7 at the lower part of the film 5 and a light source 1 and a light receiver 2 at an upper part and the thickness of the film 5 is calculated from the three measurement values.

Title: Treatment of harmful organic halide for making the same harmless
Inventor: TAKIGAWA YUJI
IPC: A62D101/28
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To treat harmful org. halides to make them harmless by decomposing the org. halides by bringing them into contact with powdery calcium hydroxide having a higher specific surface area than a specified BET specific surface area in a polar solvent at a specified temp. SOLUTION: Harmful org. halides are decomposed by bringing them into contact with powdery calcium hydroxide having >=35 m<2> /g a BET specific surface area in a polar solvent at 100-300 deg.C, preferably 200-250 deg.C. In the case of <35 m<2> /g BET specific surface area of the calcium hydroxide, it is not preferable because the contact area with the harmful org. halides decreases and the contact efficiency lowers. The polar solvent is preferably a hydroxyl group-contg. polar solvent, in particular an alcohol. When a treatment temp. is <100 deg.C, it is disadvantageous because an excessively long decomposition time is required and when a treatment temp. is >300 deg.C, it is also disadvantageous because an excessively high energy cost is required.

SOLUTION: A processing punch 14 is shifted to the arrow mark direction toward a movable die 11 to apply the pressure to the molten metal 13. At this time, about 1-2mm of the lower end part of each fin body 8 is inserted into the molten metal 13. When the lower end parts of the fin bodies 8 contact with molten copper 13, since the m.p. of aluminum is lower than the m.p. of the copper, the surfaces of the fin bodies 8 are melted and the base 7 and the fin bodies 8 are alloyed. In the case solid solution forms ordered lattice, the slippage is regulated and the strength at the joining positions of the base 7 and the fin bodies 8 is increased. Further, a compound is formed with the copper and the aluminum, and at the time of forming a compound between this compound and the component metals or the solid solution, the joining strength is further improved.

Abstract: PURPOSE:To detect the use quantity of electric power, etc., with high accuracy by a simple circuit configuration by providing a reflecting part in addition to a measuring scale, photodetecting a reflected light from this reflecting part by a photodetecting means, and converting it to an electric signal by a converting means. CONSTITUTION:A digit wheel 1 is operated by a rotation of a disk being proportional to electric energy. A reflection type photosensor 2 is arranged on the lower face opposed to the outside peripheral surface of the digit wheel 1, and outputs infrared rays 3.

In such a state, in the reflection type photosensor 2, in the case the infrared ray 3 of the photosensor 2 opposed to the reflecting part 5 hit against a black part of the reflecting part 5, they are not reflected, therefore, a phototransistor in the photosensor 2 does not operate, and on the other hand, when the opposed surface is a white ground, the infrared ray 3 are reflected and the phototransistor operates. By repeating it, it can be detected as a pulse being proportional to a rotation. Accordingly, the phototransistor photodetects an optical signal, and it is converted to an electric signal by a converting means, therefore, the use quantity of electric power, etc., can be measured by a simple circuit configuration.
