A composite article that can be used as a substrate for coated conductors is disclosed. The composite substrate has at least three layers in which one or more inner layers of Ni—W alloys with 9 at. %-13 at. % W and two outer layers of Ni—W alloys with 3 at. %-9 at. % W. The content of W element gradually decreases from the inner layers to the outer layers. The composite substrate can be prepared using a process of designing and sintering composite ingot, rolling composite ingot and then annealing composite substrate. The composite substrate have a dominant cube texture on the outer layer of the whole substrate which have a weaker magnetism and higher strength than that of a single Ni-5 at. % W alloy substrate. the preformed composite ingot is prepared by filling and compacting the Ni—W mixed powders into a mold layer by layer according to the structure of composite substrate; in said mold, said preformed composite ingots are with the total thickness of 5-250 mm, the thickness of two outer layers being 2/9-⅔ of the total thickness.

Television content from multiple sources is described. In embodiment(s), a television client device includes an interface to receive television media content in multiple streaming video formats. A television media service implemented in the television client device can process television media content when received in a first streaming video format, and render the television media content for display. In addition, the television media service can process additional television media content when received in a second streaming video format, and render the additional television media content for display.

The method of the present invention can obtain the composite substrate with high mechanical strength and reduced magnetization owing to the use of the Ni alloy with high W content in the inner layers of the composite substrate.
摘要:
A system is described that is specifically adapted for use in a resource-constrained set-top box environment. The system uses an interpreter-based common language runtime (CLR) that is specifically configured for use in the set-top box environment. The system also includes a unique application manager and UIpane manager that are specifically configured for use in the set-top box environment. The application manager pauses a current application when another application presents a user interface presentation which interferes with the current application's user interface presentation. In addition, the system includes graphics functionality for providing transitions effects, for allowing a user to change color palette and resolution, and so forth. The graphics functionality directly uses the graphics capabilities of the set top box (such as the set top box's line control register) whenever possible to enable applications to execute more quickly.
摘要:
A method for producing a single-walled carbon nanotube product by a hydrogen arc discharge method includes providing an anode including graphite powder, catalyst metal, and a growth promoter in an atmosphere containing hydrogen; providing a cathode in the atmosphere; and inducing an electric arc across the anode and cathode to thereby consume the anode and produce the single-walled carbon nanotube product. Additionally, the single-walled carbon nanotube product may be soaked in an acid or an oxidative reactant and heated under vacuum to produce a hydrogen storage material.

A method for synthesis of 1-decene oligomer is provided, wherein 1-decene is polymerized at 80-120° C., 0.8-1.4 MPa in the presence of aluminum trichloride catalyst supported on gamma-alumina and n-hexane solvent where the volume ratio of 1-decene to n-hexane is 3:8-4:1. The catalyst is treated as follows: impregnating gamma-alumina carrier in 0.5-2.0 M of hydrochloric acid, sulfuric acid, nitric acid or mixtures thereof, then vacuum drying at 80-100° C. and calcining at 400-800° C.; dissolving 5-10 g of anhydrous aluminum trichloride in 100 ml of tetrachloromethane, trichloromethane or dichloromethane solvent; adding the obtained solution into 10-20 g of activated alumina carrier and obtaining the catalyst after vacuum drying. The conversion of 1-decene is 50 wt % or more. The oligomer has a kinematic viscosity at 40° C. of 6.0-25 mm2/s and a viscosity index of 160-262.
