Abstract: A dispersion liquid contains fine particles of core-shell type inorganic oxide that have high dispersion stability and transparency and allow for excellent light resistance and weather resistance by being mixed in a coating film. The fine particles are produced by treating the surfaces of (a) fine particles of titanium-containing metal oxide serving as core particles with a hydrate and/or an oxide of a metal element such as zirconium to provide surface-treated particles or fine particles of titanium-containing metal oxide having (b) an intermediate layer and by covering the surfaces of the surface-treated particles to form (c) a shell layer with a composite oxide of silicon and at least one metal element selected from aluminum, zirconium, and antimony.

Abstract: A housing of an air cleaner has an air inlet port and an air outlet port, and incorporates an air filter. In the housing, a fuel adsorption filter is arranged downstream of the air filter in such manner as to intersect an air passage. An open portion and a sheet-like adsorption portion are vertically defined in an outer frame of the fuel adsorption filter. The adsorption portion has a fuel adsorbing function. A weir is provided in a boundary between the open portion and the adsorption portion. The weir limits air flow from the upstream side of the adsorption portion to the upstream side of the open portion. A flow straightening plate having a flow straightening function is provided in the open portion.

Abstract: The present invention relates to a coating composition containing metal oxide particles with a high refractive index and low photocatalytic activity and a coating film obtained by applying the coating composition onto a substrate. The coating composition contains metal oxide particles with a high refractive index obtained by coating the specific fine particles of the titanium-based oxide on their surfaces with at least a silica-based oxide or a silica-based composite oxide, and the coating film is obtained by applying the coating composition onto a substrate. The metal oxide particles with not only a high refractive index but also low photocatalytic activity, and therefore a coating film with excellent weathering resistance and light resistance can be formed on a substrate.
