  • Publication number: 20100096114
    Abstract: A coating composition including ultrafine silica particles having an average particle diameter of 15 nm or less and fluororesin particles, in which ultrafine silica particle content is 0.1 to 5 mass %, and the mass ratio of the ultrafine silica particles to the fluororesin particles is 70:30 to 95:5. According to the coating composition, there is provided a coating film which makes it possible to readily coat the surfaces of various articles without impairing the color tone and the texture and which is excellent in antisoiling performance and durability.

  • Patent number: 6708516
    Abstract: An air conditioner having an air blower (1) for air blowing, a front heat exchanger (2) and a rear heat exchanger (3) respectively provided on the front side and the rear side of an indoor unit (10) so as to surround the air blower (1) and for carrying out heat exchange between the indoor air and a refrigerant, a rear drain pan (11) provided under this rear heat exchanger (3) and for receiving drained water, and an air blower air path (4) formed around the air blower (1) and narrowed near the front end portion of the drain pan (11). The lower portion of the rear heat exchanger (3) is located rearward in comparison with the upper portion of the rear heat exchanger (3) so as to be inclined backward.

  • Patent number: 6692223
    Abstract: To obtain an air conditioning apparatus which provides a favorable atmosphere to the ear and saves energy even if the suction resistance of the impeller becomes high due to such as dust in the air conditioning apparatus. The air conditioning apparatus is provided with an impeller which is formed by a plurality of vanes and a ring for supporting the plurality of vanes, and includes a nozzle portion formed by a stabilizer and an air outlet, a cross flow fan formed by a guide wall, and a heat exchanger. The ratio H/&phgr;D2 of the outside diameter &phgr; D2 of the impeller to the height H of the air conditioning apparatus is 2.2 or above and 3.0 or below.
