  • Patent number: 8081420
    Abstract: On a surface of an anode member 12 having a valve action, a cathode layer 14 is formed, and at a terminal lead-out face 12a at one end of the anode member 12, an anode wire 16 is led out of it; thus a capacitor element 10 is formed. An anode terminal 4 is joined to the anode wire 16. A cathode terminal 5 is joined to the cathode layer 14. A protective layer 2 of resin covers part or all of the capacitor element 10. A packaging member 3 of resin harder than the protective layer 2 covers around the capacitor element 10 including the protective layer 2 and the anode wire 16 to form a package. The protective layer 2 has a larger linear expansion coefficient than the packaging member 3. The mass ratio of the packaging member 3 to the total mass of the packaging member 3 and the protective layer 2 between the terminal lead-out face 12a and the exterior face of the packaging member 3 opposite the terminal lead-out face 12a is 50% or more.

  • Publication number: 20080032115
    Abstract: A corrosion-resistant member used in a corrosive environment includes a substrate, and a ceramic sprayed film, which covers a part or all of the substrate surface and has relative density of 80% or greater. Maximum diameter of voids existing in the ceramic sprayed film surface is 25 ?m or less. This corrosion-resistant member is obtained by using Y2O3 as a material having a bulk density of at least 1.5 g/cm3 and dried to a moisture content of 1 mass percent or less and spraying plasma on the substrate with an output power of 40 to 110 kW by a spraying device including two anode torches.

  • Patent number: 7080523
    Abstract: In an air conditioning apparatus for a vehicle, a distance between the vehicle and a forward vehicle is detected. When the distance is equal to or less than a predetermined distance, a pollutant threshold of a concentration of exhaust gas pollutants is changed from a first level to a second level that is lower than the first level. Then, it is determined whether the concentration of exhaust gas pollutants is equal to or less than the second level. When the concentration is greater than the second level, an inside air mode is selected. When it is determined that the distance is greater than the predetermined distance, it is determined whether the concentration is equal to or greater than the first level of the pollutant threshold. When the concentration is greater than the first level, the inside air mode is selected.
