Patent number: 7267863Abstract: A film stack and method of forming a film stack are provided in which a first film is disposed on a substrate and a second film has an inner surface disposed on the first film. The second film has a thickness smaller than a reference thickness at which the second film would begin to dewet from the substrate if the second film were disposed directly on the substrate. However, the second film is substantially free of dewetting defects because it is disposed overlying the first film which has a first Hamaker constant having a negative value with respect to the substrate.Type: GrantFiled: June 30, 2004Date of Patent: September 11, 2007Assignee: International Business Machines CorporationInventors: Colin J. Brodsky, Wai-Kin Li, Steven A. Scheer

Publication number: 20070207291Abstract: A recording medium cartridge and producing method thereof, such that slidability of resin-fabricated members of different materials against one another can be assured even in conditions in which impacts are successively applied. The recording medium cartridge is provided with a recording medium T and a plurality of resin-fabricated components. A mixture C of perfluoropolyethylene and polytetrafluoroethylene is interposed at boundary surfaces at which the resin-fabricated components of different material slide against one another and/or at boundary surfaces at which the resin-fabricated components of different material slide against one another.Type: ApplicationFiled: March 2, 2007Publication date: September 6, 2007Applicant: FUJIFILM CorporationInventor: Kazuo Hiraguchi

Patent number: RE40516Abstract: A composite article is provided which includes a blend component comprising a vinylidene fluoride containing fluoropolymer and a substantially non-vinylidene fluoride containing fluoropolymer, and a component including a substantially non-fluorinated polymer having pendant amine groups intimately bonded to the blend component. Increased adhesion is observed by a greater peel strength value between the blend component and a substantially non-vinylidene fluoride containing fluoropolymer when compared to a peel strength value between a substantially non-vinylidene fluoride containing fluoropolymer and the substantially non-fluorinated polymer having pendant amine groups.Type: GrantFiled: September 11, 2002Date of Patent: September 23, 2008Assignee: 3M Innovative Properties CompanyInventors: Edward E. Parsonage, Thomas J. Blong
