  • Publication number: 20050064277
    Abstract: An electric power generation cell 1 is constituted by arranging a fuel electrode layer 4 on one side of a solid electrolyte layer 3 and an air electrode layer 2 on the other side of the solid electrolyte layer 3. The solid electrolyte layer 3 is constituted of an oxide ion conductor mainly composed of a lanthanum gallate based oxide. The fuel electrode layer 4 is constituted of a porous sintered compact having a highly dispersed network structure in which a skeletal structure formed of a consecutive array of metal grains is surrounded by mixed conductive oxide grains. For the air electrode layer 2, a porous sintered compact mainly composed of cobaltite is used. This configuration reduces the overpotentials of the respective electrodes and the IR loss of the solid electrolyte layer 3, and accordingly can actualize a solid oxide type fuel cell excellent in electric power generation efficiency.

  • Patent number: 6846375
    Abstract: The present invention provides a method of manufacturing a low-temperature sintering multilayer ceramic wiring board comprising the steps of: forming a wiring layer by printing conductive paste (4) on an unfired green sheet (1); forming a laminate by laminating, on at least one side of a ceramic substrate, the unfired green sheet having the wiring layer; and firing the laminate. The present invention also provides paste for use with this method. In the firing step, after an adhesive layer (8) or binder resin in said green sheet used for lamination burns, glass ceramic in the green sheet starts to sinter, and upon or after the start of sintering of the glass ceramic, conductive particles in the conductive paste starts to sinter. This manufacturing method can provide an precise wiring board without pattern deformation and also provide a low-temperature ceramic multilayer wiring board that has no cracks in the glass ceramic on the periphery of electrodes and has electrodes of a dense film structure.

  • Publication number: 20030147990
    Abstract: A resin ring 51 is press-fitted into a grove portion formed in an inner periphery surface of an interlocking ring 4. The resin ring 51 is made of a hard resin such as Teflon. The resin ring 51 as a low frictional lubricative member is interposed between the interlock ring 4 and an outer periphery ring 3. In addition, a cavity 6 as a closed space is formed between a stamper 1b as a molding surface of a fixed side mirror 1 and a mirror side molding surface 2b of a moving side mirror 2. While the moving side mirror 2 is being press-contracted to the fixed side mirror 1, when a resin material is filled into the cavity 6, the outer periphery ring 3 is slidably held in a groove of the moving side mirror 2 with predetermined clearances. In the interlock ring 4, a plurality of openings 4a which relieve gas produced by the disc resin material filled into the cavity 6 are formed.

  • Patent number: 6372158
    Abstract: A paste of the present invention comprises a precious metal organic acid salt added to precious metal powder as a precious metal component of the conductive paste. The base metal organic acid salts are also used instead of base metal components in the inorganic binders to exclude particles with larger diameters from the conductive paste. The conductive paste of the present invention allows the lumps in the paste caused by the insufficient dispersion to be 10 &mgr;m &PHgr; or less, thereby remarkably reducing the screen blockage during screen printing of wiring pattern of 100 &mgr;m or less in width.

  • Patent number: 6347584
    Abstract: A method of manufacturing electronic components using intaglio transfer printing for improving printing yield. Intaglio 1 having a dual releasing layer structure is used. In this structure, first releasing layer 2 is formed on the surface of intaglio 1 by chemical absorption, and second releasing layer 3 is formed on the first releasing layer by physical adsorption. This structure allows intaglio 1 to have stable releasing ability, thereby improving the printing yield. In addition, because second releasing layer 3 can be added as required, the printing yield is not decreased even when the intaglio is repeatedly used for printing. Furthermore, the dual releasing layer structure can improve durability of the releasing ability of intaglio 1. As a result, patterns for electronic components can be formed on substrates at an excellent yield.

  • Patent number: 6141847
    Abstract: A ceramic substrate 1 made of magnetic substance on which an inductor 2 is formed is prepared. A ceramic substrate 3 made of dielectric substance on which a capacitor 4 is formed is also prepared. An intermediate layer 5 made of lass paste is printed on the inductor 2 and the capacitor 4. After debinding the substrates 1 and 3 independently, both the substrates are filed with the intermediate layer 5 therebetween so that both the substrates may be glued and integrated. As such, because the debinding process is provided before filing, less gas is generated in firing, and as a result, voids are restrained from occurring.

  • Patent number: 6129849
    Abstract: In treatment of water by injection of ozone into the water for removal of harmful matters, odor matters, and color matters therein, either or both of a nonyl phenol and a cresol are added to the water to be treated. The nonyl phenol is added together with a lower alcohol or acetone to the water to be treated. The cresol is added together with a lower alcohol or acetone to the water to be treated. A p-nonyl phenol is added as the nonyl phenol for treatment. As the cresol for addition, a p-cresol is added. As the nonyl phenol for addition, a nonyl phenol is used such that two molecular weights of 220 and 107 are detected when measured by either or both of gas chromatography and mass spectrometry. By the above treatment, the decomposition reaction of ozone can be accelerated, and thereby it becomes possible to accelerate the oxidative decomposition reaction of organic matters, the amount of ozone required for the decomposition of harmful matters can be reduced with the decomposition time.

  • Patent number: 5662755
    Abstract: A method of making a multi-layered ceramic substrate which includes the steps of laminating a desired number of green sheets each being made of glass ceramics containing at least an organic binder and a solvent and each having a pattern of electrodes formed thereon by the use of an electroconductive paste, to thereby provide a green sheet laminate, The electrodes on opposite surfaces or an entire surface layer of the green sheet laminate are subsequently printed with a paste comprising an inorganic component added with at least an organic binder containing a Zn composition. On each surface of the laminate printed with the paste of the Zn composition, a green sheet made of an inorganic composition incapable of being sintered at a temperature of crystallization of the glass ceramics is then laminated thereby providing a laminate plate which is subsequently fired.
