  • Patent number: 11153422
    Abstract: A fixing structure for a plate-shaped member is configured such that before the plate-shaped member and a case are fastened together with the screw in a fastening region composed at least of a first extremity and a screw mount, the plate-shaped member and the screw mount form an interval. The interval includes a first interval adjacent to the middle of the case, and a second interval adjacent to the outside of the case. The first interval is larger than the second interval.

  • Patent number: 10167562
    Abstract: A catalyst for an oxygen evolution reaction has a higher and longer-life catalytic activity than that of the conventional and expensive noble metal oxide catalysts, such as RuO2 and IrO2. An A-site ordered perovskite oxide catalyst (such as CaCu3Fe4O12 and CaMn3Mn4O12 etc.) as an oxygen evolution reaction catalyst is excellent in cost effectiveness. The catalyst has a high catalytic activity compared with a noble metal oxide catalyst, and a long repetition use life since it is extremely stable also under the oxidative reaction conditions. Use of the catalyst is expected to the important energy conversion reactions such as a charge reaction of a metal-air battery, an anode oxygen evolution reaction in the case of a direct water decomposition reaction by sunlight, etc.

  • Publication number: 20130287625
    Abstract: Provided is a high hardness ultra-fine cemented carbide with a Ni binder phase for a wear resistant tool. An ultra-fine cemented carbide having high specularity and/or high strength, high hardness, and high wear resistance is obtained by using an ultra-fine raw powder of WC, controlling the amount of Ni, and the contents of V and Cr, so that a third phase containing V and Cr precipitates in a microstructure of the cemented carbide in a finely dispersed state, and at the same time, the size of Ni pool is controlled to a value equal to or less than the average grain size of WC. By using this cemented carbide, the range of application to an aspherical glass lens mold, an ultrahigh pressure generation container for neutron diffraction experiment, a non-ferromagnetic corrosion resistant and wear resistant tool, and the like is expanded.

  • Publication number: 20100190530
    Abstract: In a foldable portable terminal, a display device 6 is contained in a first housing 2. The display device 6 includes a display panel 4 that is longer in a lateral direction, and a driver 5 for driving the display panel 4. A pair of first hinge bearing portions 2a are respectively formed at lower right and left ends of the first housing 2 so as to protrude beyond the front surface of the first housing 2 with respect to the display panel 4. An operation section 8 is contained in a second housing 3, and a pair of second hinge bearing portions 3a are formed at an upper end of the second housing 3 so as to protrude horizontally between the first hinge bearing portions 3a. An open/close shaft is disposed in each of right and left pairs of the first hinge bearing portion 2a and the second hinge bearing portion 3a which are rotatably coupled with each other, in order to foldably connect the first housing 2 and the second housing 3 to each other.

  • Patent number: 6756670
    Abstract: An electronic device comprising a substrate having a frame, a metal lead and an electronic parts in a bonding structure, and a molding of an organic resin formed on the substrate, wherein the surface of the organic resin is provided with a hardened water-resistant or carbonaceous film or wherein pores at the surface of the organic resin are filled within an inactive gas such as argon because of a plasma treatment of the resin surface with the inactive gas whereby impurities are prevented from entering into the organic resin through the pores.
