The composite particles suppress discoloration, decomposition and photocatalytic reaction of titanium oxide by ultraviolet rays and show excellent resistance against hydrogen fluoride. Discoloration, changes in visible light transmittance, and decreases in the mechanical strength of coating compositions, printing inks, and resin films coated with printing inks containing the composite particles are suppressed for long periods of time.Type: GrantFiled: June 22, 2009Date of Patent: August 23, 2011Assignee: Asahi Glass Company, LimitedInventor: Hiroshi Aruga

Patent number: 7998581Abstract: A solid particle erosion resistant surface treated coating has a solid particle erosion resistance that is largely enhanced and a rotating member having the coating gains oxidation resistance without deteriorating a fatigue strength. Also, a rotating machine can have this coating applied thereto. The solid particle erosion resistant surface treated coating has a nitrided hard layer formed on a surface of a base material and a PVD (physical vapor deposition) hard layer of at least one layer formed on the nitrided hard layer by a PVD method. Deformation of the base material by collisions by solid particles is prevented and cracking of the coating is prevented. Thereby, the solid particle erosion resistance is secured, life of the solid particle erosion resistant surface treated coating can be increased and oxidation resistance and fatigue strength are enhanced.Type: GrantFiled: January 18, 2006Date of Patent: August 16, 2011Assignee: Mitsubishi Heavy Industires, Ltd.Inventors: Toyoaki Yasui, Yoshikazu Yamada, Shugo Iwasaki, Katsuyasu Hananaka, Kyoichi Ikeno

Patent number: 7998907Abstract: Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials. Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments. Porous materials may also be employed in selected combinations to optimize fracture or sand control performance, and/or may be employed as relatively lightweight materials in liquid carbon dioxide-based well treatment systems.Type: GrantFiled: May 10, 2010Date of Patent: August 16, 2011Assignee: Baker Hughes IncorporatedInventors: Christopher John Stephenson, Allan Ray Rickards, Harold Dean Brannon, D.

Patent number: 7989065Abstract: Magnetically responsive particles can include two or more magnetically responsive layers (“MRL”). As such, the particles can have the following: a polymeric core; a first magnetically responsive layer (“MRL”) on the core; a first polymeric layer bound to the first MRL; a second MRL layer bound to the first polymeric layer; and a second polymeric layer bound to the second MRL. The particles can have a faster magnetic response time compared to a similar particle having only a single MRL, which can be at least 25% faster. Also, the particle can have a magnetic squareness of less than about 0.1. Preferably, the particle can have negligible residual magnetism after being exposed to a magnetic field sufficient for the particle to respond thereto. Further, the particle can be colloidally stable in water at concentrations from about 0.1 to 10 grams of particle per 100 milliliters of water.Type: GrantFiled: May 18, 2006Date of Patent: August 2, 2011Assignee: Seradyn, Inc.Inventors: J Winstead, William L.
