Abstract: A fortified adobe-type construction composition includes soil, from about 12 to about 14 parts; water, from about 3 to about 4 parts; flyash, from about 2 to about 4 parts; and cement, from about 1 to about 2 parts. A wall structure includes a frame structure having spaced-apart frame elements and a support structure affixed thereto to form an interior space. A core material resides within the space, and the overlay composition is applied to an exterior surface. A method of constructing a building element includes the steps of erecting a frame structure comprising spaced-apart frame elements and affixing a support structure to the elements to form an interior space. A core material is inserted into the support structure interior space, and the overlay composition is applied to an exterior surface of the support structure.

Abstract: A hydrophilic treatment by the use of a surface active agent and the like is not required for a base even the surface of which is water-repellent or thermoplastic when a viscous amorphous type titanium peroxide is used for fixing a base as a binder. In addition, a thin layer of a photocatalyst semiconductor, a dielectrical ceramics or an electrical ceramics can be easily formed by adhering particles of a photocatalyst semiconductor, a dielectrical ceramics or an electrical ceramics to the layer of a viscous amorphous type titanium peroxide, which is a layer as a binder, in a homogeneously floating state gas. Furthermore, a layer of a titanium oxide having a photocatalyst function can be formed when a base is fixed with a viscous amorphous type titanium peroxide.

Abstract: A three-dimensional, photocatalytic filter apparatus is constituted by (a) a flow path means through which a fluid stream containing pollutants passes; (b) a plurality of porous filter plates each carrying a photocatalyst for decomposing the pollutants; (c) a light source; and (d) at least one support member for arranging each porous filter plate in a path of the fluid stream in the flow path means, at such a three-dimensional position that each porous filter plate is inclined relative to both the fluid stream and the light source, to achieve sufficient contact with the pollutants and sufficient exposure to the light source.

Abstract: A photocatalytic sheet which has a base made of polymeric organic compound, that is not decomposed by a photocatalytic function, and also hardly loses the photocatalytic function after washing and is capable of providing the photocatalytic function even in an environment without sufficient ultraviolet radiation from outside. Using a fiber, a filament, a yarn made of fibers or filaments, a ribbon, a knitted fabric, a woven fabric, a nonwoven fabric, or a film as the base, a base protective layer is formed on a part of the base, which is made of the polymeric organic compound, and a photocatalytic semiconductor layer is formed on the entire surface of the base including the base protective layer.

Abstract: The invention relates to a photocatalytic body having a good photocatalytic function characterized by using an amorphous titanium peroxide sol, and a method for making the same. A photocatalyst such as titanium oxide in the form of powder or a sol and an amorphous titanium peroxide sol are mixed in different mixing rations depending on the purpose in use and the resultant mixture is coated onto a substrate such as an organic polymer resin, dried-solidifed and/or baked to support and fixed the photocatalyst on the substrate to make a photocatalytic body. Alternatively, a first layer consisting of an amorphous titanium peroxide sol on a substrate, and a second layer made of a photocatalyst is formed on the first layer to make a photocatalytic body. According to the invention, the photocatalyst can be supported and fixed on the substrate without lowering the photocatalytic function of the photocatalyst to obtain a photocatalytic body which is usable over a long time.

Abstract: A coating agent including amorphous titanium peroxide. Preferably, the amorphous titanium peroxide is a sol. Additionally, a coated substrate includes a substrate; and a coating provided on at least one surface of the substrate and comprised of the coating agent.

Abstract: A molded article having a photocatalytic function, a desired shape, a large contact area, and being sufficiently irradiated with ultraviolet rays, even at an inner surface thereof. Unit particles such as glass beads, or filaments such as fibers, are bonded to one another into the desired shape. Subsequently, a photocatalytic functional layer is formed on a surface of each particle or fiber. Particles of a spontaneous emission ultraviolet radiating material or light storage-type ultraviolet radiating material may be mixed in the molded article.
