Publication number: 20140339153Abstract: A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a “whiskering” problem common in prior art multifilament braid-supported tubular membranes. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilaments. When the braid is supported on a plasticized PVA cable it can be infiltrated with membrane polymer which, when coagulated embeds the braid positioning it around the lumen. The spiral weave, free of any circumferentially constricting monofilament, when embedded in film, allows the membrane to be biaxially distensible. In other words, the membrane has “give” not only in the axial or longitudinal direction but also in the radial direction. “Give” in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.Type: ApplicationFiled: July 14, 2014Publication date: November 20, 2014Inventors: Chang Min Seo, Gyeong Mo Lee

The method includes the step of introducing the organoborane-amine complex, the radical polymerizable compound, and optionally an amine, onto a substrate to form the coating composition. The method also includes the step of introducing carbon dioxide into the coating composition in a molar ratio of at least 1:1 of the carbon dioxide to free amine groups present in the coating composition. More specifically, a carbamic zwitterion is formed in-situ from reaction of the carbon dioxide and the free amine groups. The formation of the carbamic zwitterion leads to dissociation of the organoborane-amine complex and formation of a radical. The radical is then used to polymerize the radical polymerizable compound.Type: ApplicationFiled: June 24, 2010Publication date: April 26, 2012Applicant: BASF SEInventors: Keith E.

Patent number: 8097175Abstract: Methods of forming metal oxide structures and methods of forming metal oxide patterns on a substrate using a block copolymer system formulated for self-assembly. The metal oxide structures and patterns may be used, for example, as a mask for sublithographic patterning during various stages of semiconductor device fabrication. A block copolymer at least within a trench in the substrate and including at least one soluble block and at least one insoluble block may be annealed to form a self-assembled pattern including a plurality of repeating units of the at least one soluble block laterally aligned with the trench and positioned within a matrix of the at least one insoluble block. The self-assembled pattern may be exposed to a metal oxide precursor that impregnates the at least one soluble block. The metal oxide precursor may be oxidized to form a metal oxide. The self-assembled pattern may be removed to form a pattern of metal oxide lines on the substrate surface.Type: GrantFiled: October 28, 2008Date of Patent: January 17, 2012Assignee: Micron Technology, Inc.Inventors: Dan B. Millward, Timothy A. Quick, J. Neil Greeley

Patent number: 7976901Abstract: A polishing sheet which can improve waviness at a face of a material to be polished and which has a long life is provided. The polishing pad 1 has a polyurethane sheet 2 made of polyurethane resin. The polyurethane sheet 2 has a polishing layer which is disposed inside a surface layer and which is allowed to wear away by polishing and whose thickness is larger than a thickness of the surface layer. The polishing layer has an approximately uniform foam structure in a direction of the thickness of the polishing sheet 2 by being formed foams whose space volume is larger than that of foams formed at the surface layer and which are communicated so as to form a network by continuous holes.Type: GrantFiled: May 11, 2009Date of Patent: July 12, 2011Assignee: Fujibo Holdings, Inc.Inventors: Takahiro Kume, Tomohiro Iwao
