Patent number: 7645835Abstract: Blend compositions containing a novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of the blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength are disclosed. The homopolymers are important for applications where a high density is needed to ensure certain mechanical properties like abrasion resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. The blend can be obtained by dry or melt mixing the already produced components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibers, and cable and wire coatings and jacketings and, various forms of pipe.Type: GrantFiled: June 21, 2006Date of Patent: January 12, 2010Assignee: Dow Global Technologies, Inc.Inventors: Jozef J.

Patent number: 7246000Abstract: An apparatus is provided that warns a vehicle of a harsh braking-applied vehicle based on information sent from the harsh braking-applied vehicle. The apparatus includes a reception device, a position detection device, a forward side vehicle judgment device, and a warning device. The reception device receives the information indicating that harsh braking has been applied to the harsh braking-applied vehicle and information indicating a position of the harsh braking-applied vehicle. The position detection device detects a position of the vehicle to be warned, and the forward side vehicle judgment device determines if the harsh braking-applied vehicle is in front of the vehicle to be warned based on the positions of the harsh braking-applied vehicle and the vehicle to be warned. The warning device warns the vehicle to be warned when the harsh braking-applied vehicle is in front of the vehicle to be warned.Type: GrantFiled: May 21, 2004Date of Patent: July 17, 2007Assignee: Pioneer CorporationInventors: Satoshi Odagawa, Fumio Matsushita, Takehiko Shioda, Katsunori Arakawa
