  • Patent number: 7935653
    Abstract: A metal oxide nanoporous material comprises two or more kinds of first metal oxides selected from the group consisting of alumina, zirconia, titania, iron oxide, rare-earth oxides, alkali metal oxides and alkaline-earth metal oxides. The metal oxide nanoporous material has nanopores, each with a diameter of 10 nm or smaller, in which the metal oxides are dispersed homogeneously in the wall forming the nanopores.
    Type: Grant

  • Patent number: 7618919
    Abstract: A method of producing a catalyst support comprising a substrate, and coating formed on the surface of the substrate and including powder of a first metal oxide of at least one member selected from the group consisting of alumina, zirconia, titania, iron oxides, oxides of rare earth elements, alkali metal oxides and alkali earth metal oxides, wherein the coating is obtained by heat treating the substrate after applied with a coating composition obtained by mixing the first metal oxide powder together with a fluid raw material composition containing raw material of a second metal oxide of at least one member selected from the group consisting of alumina, zirconia, titania, iron oxides, oxides of rare earth elements, alkali metal oxides and alkali earth metal oxides, at a shear rate of 1000 sec?1 or higher.

  • Patent number: 4319016
    Abstract: An ultraviolet-absorbing amino compound; a paint containing the aforesaid ultraviolet-absorbing amino compound; and a coated article having on its surface a coated film containing the aforesaid ultraviolet-absorbing amino compound are provided. The ultraviolet-absorbing amino compound is produced by reacting (a) a compound having a light absorption maximum within a wavelength region of 300 to 400 m.mu. and containing a mono-, di- or tetra-hydroxyphenyl group, (b) at least one compound containing a amino group and (c) formaldehyde, in the presence of at least one alcohol. The ultraviolet-absorbing amino compound of this invention is used in resin products which undergo photodegradation by ultraviolet light, for example, paints or molded articles of resins, and is especially effective for use in thermosetting synthetic resin paints.
