An anodic oxide film is formed on at least the cooling medium passage forming groove on the joining surface, and the plurality of metal plates are integrally joined each other by a friction agitation joining method. This enhances corrosion resistance of the cooling medium passage, resulting in an improved durability and extended life, which enables uniform cooling performance.Type: GrantFiled: June 20, 2002Date of Patent: February 3, 2004Assignee: Showa Denko, K.K.Inventors: Shigetoshi Jogan, Kiyoshi Tada

Patent number: 6677026Abstract: A resilient cushion includes a base sheet and a cover sheet sealed to the base sheet along spaced apart strips to form a matrix of sac like areas therebetween. A gel fills each of the sac like areas and a plurality of openings through the base and cover sheets along the strips are provided for enabling the passage of a fluid therethrough. The resilient cushion may include sac like areas disposed on both sides of a base layer and the use of gels of different resiliency may be utilized to provide a tailoring of overall cushioning resiliency.Type: GrantFiled: May 4, 2001Date of Patent: January 13, 2004Inventor: Paul M. Yates

Patent number: 6677028Abstract: Retroreflective articles having multilayer films are useful for commercial graphics and retroreflective products, such as roll-up signs for highway transportation safety. The articles comprise multilayer films having at least one layer of polyurethane and at least one layer of a copolymer of alkylene and at least one non-acidic, polar co-monomer. Articles having the new multilayer films provide the same or improved performance, are less expensive, and offer improved methods for manufacturing, when compared to prior articles.Type: GrantFiled: August 10, 2000Date of Patent: January 13, 2004Assignee: 3M Innovative Properties CompanyInventors: James E. Lasch, Paul J. Wang, Raymond L. Lucking, Terry R. Bailey, Kanta Kumar, Michael A. Essien, Jeffrey D. Janovec, Jaime R. Ojeda, Michael D. Currens

Patent number: 6676835Abstract: Microfluidic separators for separating multiphase fluids are described. Two or more microfluidic outlet channels within the device meet at an overlap region. The overlap region may be in fluid communication with an inlet channel. The inlet channel and each outlet channel are disposed within different layers of a three-dimensional device. Each channel is defined through the entire thickness of a stencil layer. A multiphase fluid flows through an inlet channel into an overlap region from where the separated phases can be withdrawn through the outlet channels.Type: GrantFiled: April 23, 2002Date of Patent: January 13, 2004Assignee: Nanostream, Inc.Inventors: Stephen D. O'Connor, Christoph D. Karp

Publication number: 20040005438Abstract: A collapsible cellular insulation panel for use with mobile shelters is provided. The panel comprises first and second outer sheets with a plurality of intermediate thin flexible membranes. The membranes are secured along first and second edges to inner surfaces of the outer sheets. The membranes are attached to adjacent membranes along strips that are parallel to and intermediate the first and second membrane edges. The interconnected membranes form cells that trap insulating air and break up convective currents between the outer sheets. Supported from underneath on a horizontal surface, the membranes lay substantially flat, such that a thickness of the panel substantially equals the sum of the thicknesses of the membranes and outer sheets. The panel is thus well adapted for use with mobile shelters, because it occupies little volume in the collapsed state.Type: ApplicationFiled: May 15, 2003Publication date: January 8, 2004Inventors: David Lichodziejewski, Mitchell Thomas
