20080241522	THERMAL SPRAYING POWDER, THERMAL SPRAY COATING, AND HEARTH ROLL - A thermal spraying powder contains 30 to 50% by mass of chromium carbide with the remainder being an alloy containing chromium, aluminum, yttrium, and at least one of cobalt and nickel. The thermal spraying powder has an average particle size of 20 to 60 μm. The thermal spraying powder may contain 20% by mass or less of yttrium oxide in place of a part of the alloy. A thermal spray coating obtained by thermal spraying of the thermal spraying powder, particularly, a thermal spray coating obtained by high-velocity flame spraying of the thermal spraying powder is suitable for the purpose of a hearth roll.	10-02-2008
20080245185	THERMAL SPRAY POWDER AND THERMAL SPRAY COATING - A thermal spray powder including cermet particles, each of which contains metal containing at least one selected from the group consisting of cobalt, chrome, and nickel, and tungsten carbide. The ratio of the summed weight of cermet particles having a particle size of 25 μm or more in the thermal spray powder with respect to the summed weight of the entire cermet particles in the thermal spray powder is 0.5 to 15%. A thermal spray coating formed from the thermal spray powder is suitable for the formation of a tungsten carbide-based cermet thermal spray coating for use in rolls such as corrugated rolls.	10-09-2008

20120154088	REACTOR AND PRODUCTION METHOD THEREOF - A reactor which may be employed in an inverter for automotive vehicles. The reactor includes a coil, a core, a casing, and a positioning member. The core is made of a solidified magnetic powder/resin mixture and has the coil embedded therein. The positioning member is disposed in the casing to position the coil relative to the casing and equipped with fins configured to stir the magnetic powder/resin mixture before solidified. Specifically, the positioning member is designed to perform two functions: one is to fax the location of the coil within the casing, and the other is to stir the magnetic powder/resin, mixture through the fins, thus eliminating the need for removing a portion of the magnetic powder/resin mixture adhered to the fins, which leads to improved productivity of the reactor.	06-21-2012
20130032964	METHOD OF MANUFACTURING MOLDED ARTICLE INCLUDING COMPONENT INSERT-MOLDED IN RESIN MIXED WITH SOLID POWDER - The exemplary embodiment provides a method of manufacturing a molded article including a component insert-molded in a molding material mixed with solid powder. The method includes an injecting step of injecting the molding material and the solid powder into a molding die, an agitating step of agitating the molding material and the solid powder within the molding die to disperse the solid powder in the molding material, and an embedding step of pressing and embedding the component into the agitated mixture of the molding material and the solid powder while vibrating at least one of the component and the molding die.	02-07-2013
20130032966	METHOD OF MANUFACTURING MOLDED ARTICLE INCLUDING COMPONENT INSERT-MOLDED IN MOLDING MATERIAL MIXED WITH SOLID POWDER - The method of manufacturing a molded article including a component insert-molded in a molding material mixed with solid powder includes an injecting step of injecting the molding material and the solid powder into a molding die, an agitating step of agitating the molding material and the solid powder within the molding die to disperse the solid powder in the molding material, and an embedding step of pressing and embedding the component into an agitated mixture of the molding material and the solid powder.	02-07-2013

20140234634	THERMAL SPRAY POWDER AND FILM THAT CONTAIN RARE-EARTH ELEMENT, AND MEMBER PROVIDED WITH FILM - A thermal spray powder of the present invention contains a rare earth element and a diluent element that is not a rare earth element or oxygen, which is at least one element selected, for example, from zinc, silicon, boron, phosphorus, titanium, calcium, strontium, and magnesium. A sintered body of a single oxide of the diluent element has an erosion rate under specific etching conditions that is no less than 5 times the erosion rate of an yttrium oxide sintered body under the same etching conditions.	08-21-2014
20140234653	THERMAL SPRAY POWDER AND FILM THAT CONTAIN RARE-EARTH ELEMENT, AND MEMBER PROVIDED WITH FILM - A thermal spray powder of the present invention contains a rare earth element and a group 2 element, which belongs to group 2 of the periodic table. The thermal spray powder, which contains a rare earth element and a group 2 element, is formed, for example, from a mixture of a rare earth element compound and a group 2 element compound or from a compound or solid solution containing a rare earth element and a group 2 element. The thermal spray powder may further contain a diluent element that is not a rare earth element or a group 2 element and is not oxygen, which is at least one element selected, for example, from titanium, zirconium, hafnium, vanadium, niobium, tantalum, zinc, boron, aluminum, gallium, silicon, molybdenum, tungsten, manganese, germanium, and phosphorus.	08-21-2014
20140360407	YTTRIUM OXIDE COATING FILM - An yttrium oxide coating has a porosity of 1.5% or less and contains monoclinic yttrium oxide at a ratio of 1% or more and 30% or less to the sum of monoclinic yttrium oxide and cubic yttrium oxide in the coating.
