Patent number: 8067058Abstract: The amount of a paint for forming a porous heat-resistant layer supplied to the outer surface of a gravure roll is adjusted by removing the paint with a blade that is disposed so as to contact the outer surface. A resin blade is used, and the position at which the resin blade contacts the outer surface of the gravure roll is changed as the resin blade wears away. This prevents the amount of the paint for forming the porous heat-resistant layer removed from the outer surface of the gravure roll from changing as the resin blade wears away, so that the excess amount of the paint carried on the outer surface of the gravure roll is removed with good accuracy. An almost constant amount of the paint is thus transferred to an electrode surface from the outer surface of the gravure roll, and a porous heat-resistant layer with an almost uniform thickness is stably formed on an industrial scale.Type: GrantFiled: December 25, 2007Date of Patent: November 29, 2011Assignee: Panasonic CorporationInventors: Tetsuya Hayashi, Akira Motoi, Yasuhiko Takeuchi

Patent number: 8029851Abstract: Techniques for making nanowires with a desired diameter are provided. The nanowires can be grown from catalytic nanoparticles, wherein the nanowires can have substantially same diameter as the catalytic nanoparticles. Since the size or the diameter of the catalytic nanoparticles can be controlled in production of the nanoparticles, the diameter of the nanowires can be subsequently controlled as well. The catalytic nanoparticles are melted and provided with a gaseous precursor of the nanowires. When supersaturation of the catalytic nanoparticles with the gaseous precursor is reached, the gaseous precursor starts to solidify and form nanowires. The nanowires are separate from each other and not bind with each other to form a plurality of nanowires having the substantially uniform diameter.Type: GrantFiled: August 29, 2008Date of Patent: October 4, 2011Assignee: Korea University Research and Business FoundationInventor: Kwangyeol Lee
