One to a plurality of this base material are stacked to constitute a first damping structure. A second damping structure is constituted by stacking at least a layer of piezoelectric polymer film or piezoelectric ceramic thin film between a multilayer laminate that is a laminate of conductive laminate FRP base materials.Type: GrantFiled: August 9, 2002Date of Patent: January 9, 2007Assignee: Kurimoto, Ltd.Inventor: Toshio Tanimoto

Patent number: 7135233Abstract: Multi-layer composite structures offer improved weatherability and adhesion to fiber-reinforced plastic substrates when compared to structures now available. These composites have an outer layer made from a polyacrylate, a second layer made from an acrylonitrile-styrene-acrylate rubber terpolymer; a third layer made from an ABS polymer; and optionally a fourth layer made from a polyacrylate. The layers include one or more layers having an improvement selected from among: (a) the improvement wherein the second layer is made from an acrylate-modified acrylonitrile-styrene-acrylate rubber terpolymer; (b) the improvement wherein the third layer is a modified ABS that further includes a polymer modifier that decreases the softening of the ABS on contact with styrene, and an acrylonitrile-styrene-acrylate rubber terpolymer; and (c) the improvement wherein the fourth layer is present and is a polyacrylate. This composite can be applied to a fiber-reinforced plastic substrate such as fiberglass as a coating.Type: GrantFiled: October 20, 2003Date of Patent: November 14, 2006Assignee: General Electric CompanyInventors: Satish K. Gaggar, Ke Feng, Donald M. Kulich, Christopher D. Willis, Craig Williams

Patent number: 7052763Abstract: An apparatus such as a connector or circuit includes a substrate having a plurality of conductive members and a plurality of non-conductive members. The conductive members include a plurality of conductive fibers in association with a polymer material. The conductive members and the non-conductive members are disposed in the substrate member and are selectively situated with respect to each other forming a modular matrix configuration of contacts suitable for an array or association with other circuitry.Type: GrantFiled: August 5, 2003Date of Patent: May 30, 2006Assignee: Xerox CorporationInventors: Joseph A. Swift, Stanley J. Wallace

Patent number: 7011730Abstract: A method to produce a papermaker's shoe press belt or other industrial process belt and a belt made according to such method. The belt is produced by dispensing a mixture of polymer and staple fiber onto a cylindrical mandrel, by extrusion or by co-extrusion. Preferably, the variation of the concentration and/or orientation of the staple fiber within the polymer is controlled such that the finished belt has desired properties.Type: GrantFiled: December 30, 2002Date of Patent: March 14, 2006Assignee: Albany International Corp.Inventor: Trent Davis

Patent number: 6919115Abstract: The present invention provides for a power transfer belt that is manufactured of a highly thermally conductive polymer composition, in contrast to the typical rubber material used to fabricate the belts of the prior art. The new and unique belt of the present invention is manufactured of a thermally conductive polymer material that is easily injection moldable into any desired shape and configuration. Further, the polymer composition is very thermally conductive, which assists in dissipating heat that is generated by the friction created during normal operation of the device. The new belt material and its construction allow heat to be conducted directly through the surface of the belt thus preventing heat buildup within the belt itself, thereby preserving and extending its life. Further, the present invention provides a novel method whereby a thermally conductive belt is manufactured through net shape molding.Type: GrantFiled: January 7, 2003Date of Patent: July 19, 2005Assignee: Cool Options, Inc.Inventor: Jon S. Foster

Publication number: 20040142618Abstract: This invention provides facing materials for cementitious boards such as those including Portland cement or gypsum cores. The preferred facing material includes, in a first embodiment, a facing layer having an areal weight of about 300 grams/M2, and an air permeability rating of no greater than about 300 CFM/ft2 (FG 436-910 test method). The facing layer reduces the penetration of a slurry of cementitious material during the manufacture of a cementitious board, while permitting the water vapor from the slurry to pass therethrough. The facing materials of this invention can be designed to substantially eliminate the fouling of rolls used in continuous processing of such boards without the use, or with greatly reduced use, of costly viscosity control agents in the slurry.Type: ApplicationFiled: January 21, 2003Publication date: July 22, 2004Applicant: Saint Gobain Technical FabricsInventor: John Frederick Porter
