20090326108 | Halogen-Free Flame Retardant Thermoplastic Polyurethanes - Disclosed is a halogen-free flame retardant thermoplastic polyurethane composite resin composition. The disclosed flame retardant thermoplastic polyurethane composite resin composition is capable of improving flame retardancy and flaming-drip of a thermoplastic polyurethane resin through desirable formation of char during combustion, which uses a phosphinate, a diphosphinate and/or a polymer thereof, dipentaerythritol, talc, a melamine derivative, etc., instead of a halogen-based flame retardant, as a flame retardant. | 12-31-2009 |
20120021198 | Transparent Multilayer Sheet Having Electrostatic Dissipative Properties - Disclosed is a transparent multilayer sheet that is excellent in antistatic properties, as well as transparency. The transparent multilayer sheet includes a surface layer comprising a conductive thermoplastic polyurethane or polyurea resin containing ethylene oxide; and a back layer attached to the surface layer and comprising a transparent non-conductive polymer resin. Preferably, the polyurethane or polyurea resin is a polymerization product of (a) a polyether-based polymer containing ethylene oxide and reacting with an isocyanate group; (b) an aromatic or aliphatic diisocyanate compound; and (c) a chain extender C2 to C10 containing a primary hydroxyl group or an amine group, and the transparent non-conductive polymer resin is selected from the group consisting of polyethylene terephthalate, glycol modified polyethylene terephthalate, glycol modified polycyclohexaneterephthalate, polymethylmethacrylate, polycarbonate, transparent acrylonitrile-butadiene-styrene (ABS), and mixtures thereof. | 01-26-2012 |

20100250557 | SYSTEM AND METHOD FOR EXTRACTING USERS OF SIMILAR INTERESTS BETWEEN VARIOUS TYPES OF WEB SERVERS - Disclosed herein is a system and method for extracting users of similar interests between various types of web servers. The system includes a user profile vector creation unit, a user similarity calculation unit, and a similar user extraction unit. The user profile vector creation unit collects tag data, performs standardization calculation on the degree of importance of each of one or more tags, and creates user profile vectors for respective users. The user similarity calculation unit calculates user similarity using the user profile vectors of the respective users created through the user profile vector creation unit. The similar user extraction unit extracts users of similar interests using the value of the user similarity calculated through the user similarity calculation unit. | 09-30-2010 |
