Patent number: 6309743Abstract: A porous preform for manufacturing partially composite lightweight metal products including at least a sliding surface as composite part is made of a hard material which comprises a sintered mixture comprising TiO2 particles, short ceramic fibers and whiskers, and SiC particles having an average particle size of approximately 20 to 100 &mgr;m. The partially composite lightweight metal product produced from the porous preform is provided with superior wear resistance and high strength and achieves increasing the coefficient of friction even though it is large in size, so as to keep a composite part of the composite lightweight metal product such as a sliding surface of a brake rotor remain even and smooth for a long period of time.Type: GrantFiled: September 28, 1999Date of Patent: October 30, 2001Assignee: Mazda Motor CorporationInventor: Makoto Fujita

Patent number: 6294247Abstract: Multi-functional materials which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through a binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.Type: GrantFiled: October 7, 1998Date of Patent: September 25, 2001Assignee: Toto Ltd.Inventors: Toshiya Watanabe, Eiichi Kojima, Keiichiro Norimoto, Tamon Kimura, Mitsuyoshi Machida, Makoto Hayakawa, Atsushi Kitamura, Makoto Chikuni, Yoshimitsu Saeki, Tatsuhiko Kuga, Yasushi Nakashima

Patent number: 6210779Abstract: Multi-functional materials which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through an amorphous binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles. A lower layer of the photocatalytic layer is embedded in the binder layer such that an intermediate layer is formed between the binder layer and the photocatalytic layer, the intermediate layer including components of the binder and photocatalytic layers in varying concentrations therethrough.Type: GrantFiled: October 7, 1998Date of Patent: April 3, 2001Assignee: Toto Ltd.Inventors: Toshiya Watanabe, Eiichi Kojima, Keiichiro Norimoto, Tamon Kimura, Mitsuyoshi Machida, Makoto Hayakawa, Atsushi Kitamura, Makoto Chikuni, Yoshimitsu Saeki, Tatsuhiko Kuga, Yasushi Nakashima

Patent number: 6171688Abstract: Composite products incorporating a polymer matrix, polymer microspheres, glass microspheres and natural fibers, particularly kenaf and wood fibers, are described. The polymer microspheres are 15 to 50 microns in diameter and are smaller than the glass microspheres which are 50 to 200 microns in diameter. The polymer microspheres reduce voids and prevent cracking of the glass microspheres upon compression. The composites have low cost and high strength.Type: GrantFiled: February 8, 1999Date of Patent: January 9, 2001Assignee: Board of Trustees operating Michigan State UniversityInventors: James Zheng, Roger J.
