  • Patent number: 10988093
    Abstract: A vehicular static eliminating device includes: a negative ion generating device; and a guide device configured to guide negative ions and release the negative ions from an emission port to a static elimination target spot which is positively charged, the guide device including: a guide member defining a passage through which to guide the negative ions, the guide member being made of a resin which is easily negatively charged in a triboelectric series; and a tip-shaped part configured to discharge, by corona discharge, negative electric charges, which have accumulated on the guide member, to the static elimination target spot, the tip-shaped part being provided in a part defining the emission port and in proximity to the static elimination target spot.

  • Patent number: 10533725
    Abstract: Disclosed is a case structure for a rear combination lamp in an automobile in which a rear combination lamp case in a corner portion formed in a rear portion of a vehicle is formed in a corner case having a substantial triangle pyramid shape by a rear plate, a side plate and a planner plate, wherein the rear plate forms a case rear face on which a concave notch portion is formed in a substantial center, wherein the side plate forms an air communication side face which is formed so as to gradually become narrower width toward a rear thereof, and wherein the planner plate forms a concave air communication path in a center thereof so that a terminal end of the concave air communication path communicates with the concave notch portion of the rear plate.

  • Patent number: 6942725
    Abstract: The invention provides a transparent and tenacious coating film using an inorganic paint composition prepared by adding a borate salt into an alkali metal silicate, and further mixing thereto lepidoblastic transparent silica with a thickness of 0.01 to 0.5 ?m and a surface diameter of 2 to 5 ?m. The alkali metal silicate is solidified with metal ions issued from the borate salt to form a coating film, which contains a glass formed by solidifying dissolved boric acid in the coating film. The coating film can be made tenacious without impairing transparency by dispersing many flakes of transparent silica as laminated layers.
