The method is such that when assembled in step (c) the membrane does not extend to at least one edge of the first and second panels, so that in that region the first and second panels are diffusion bonded directly to each other.Type: ApplicationFiled: October 8, 2014Publication date: April 23, 2015Inventors: Ian John ANDREWS, Michael James WALLIS, Ian FEARN

Patent number: 9012031Abstract: To provide a steel fuel conveying pipe which has high resistance to corrosive fuel and maintains reliability without damaging a direct-injection engine, and connects a high-pressure pump and a direct-injection rail with each other in a gasoline direct-injection engine system, and a fuel conveying pipe suitable as a bypass pipe for coupling direct-injection rails with each other in a V-type gasoline engine. A steel fuel conveying pipe for conveying gasoline is characterized in that a Ni-plated layer is provided on the whole inner circumferential face of the fuel conveying pipe, and an anti-rust film layer composed of a Zn-plated layer and a Zn-based alloy-plated layer is further provided on the Ni-plated layer at at least one end of the fuel conveying pipe.Type: GrantFiled: July 5, 2011Date of Patent: April 21, 2015Assignee: Usui Kokusai Sangyo Kaisha LimitedInventor: Kazuo Takagi

Patent number: 8962147Abstract: A powder metal component is made of compacted and sintered powder metal particles such as chromium-containing ferrous-based metal and is porous. Following sintering, the pores are impregnated with relatively smaller particles of ceria and/or yttria. The component is then heat treated and the presence of the impregnated ceria and/or yttria serve as nucleation sites for the formation of desirable oxides, such as chromium oxide, on the surface. The impregnated particles that lie below the protective oxide layer remain available throughout the life of the component in the event the original oxide layer becomes worn or damaged, wherein a renewed protective oxide is formed in such regions due to the presence of the impregnated particles.Type: GrantFiled: December 5, 2011Date of Patent: February 24, 2015Assignee: Federal-Mogul CorporationInventors: Denis Christopherson, Jr., Jeremy Koth

Patent number: 8948562Abstract: The present invention provides templating methods for replicating patterned metal films from a template substrate such as for use in plasmonic devices and metamaterials. Advantageously, the template substrate is reusable and can provide plural copies of the structure of the template substrate. Because high-quality substrates that are inherently smooth and flat are available, patterned metal films in accordance with the present invention can advantageously provide surfaces that replicate the surface characteristics of the template substrate both in the patterned regions and in the unpatterned regions.Type: GrantFiled: November 24, 2009Date of Patent: February 3, 2015Assignee: Regents of the University of MinnesotaInventors: David J. Norris, Sang Eon Han, Aditya Bhan, Prashant Nagpal, Nathan Charles Lindquist, Sang-Hyun Oh
