| 20090194265 | Heat Exchanger - In a heat exchanger in which the number of parts is small, assembling is easy, bonded portions between each part are fewer and reliability of brazing is improved, a core body is constituted by turning up and bending a strip-shaped metal plate in a fanfold manner, and first flow passages and second flow passages are formed alternately in the thickness direction. Both ends of each of the first flow passages are blocked by each comb tooth of a pair of comb-state members, and a fin is set within the second flow passages so as to constitute a core. And a cylindrical casing is fitted with the outer periphery of the core body, and the casing is constituted by a channel-state material covering three faces of the outer periphery of the core body and a lid material blocking an opening of the channel-state material. In the core body, a starting end and a terminating end of the turning-up/bending of the strip-shaped metal plate are both located on the turned-up end edge on one side, the starting end the terminating end form a fitting edge portion turned-up with the section in the U-shape conforming to the plate thickness of the channel-state material, and the end edge of the opening of the channel-state material is fitted with the fitting edge portion so as to braze/fix the both. | 08-06-2009 |
| 20090019084 | METHOD AND SYSTEM FOR PRELOADING - The invention relates to integrating a first multimedia work and a second multimedia work to produce a combined multimedia work. The first and/or second multimedia works are converted into a common format such as SWF format, and the first multimedia work is converted to a sub-movie. The converted first multimedia work is inserted into the second multimedia work as a sub-movie of the second multimedia work to produce a combined multimedia work. Instructions in the combined multimedia work are updated in order to maintain the function of those instructions following the combination of the two works. | 01-15-2009 |
| 20080251241 | Double-Pipe Heat Exchanger and Manufacturing Method Thereof - A double-pipe heat exchanger that is easy to manufacture, and the whole thereof is smoothly bent to serve as part of the piping, and that provides high pressure resistance, wherein an inner tube has a section orthogonal to an axis line thereof in which a plurality of swollen portions in a bladder-like or balloon-like shape in section are formed in a radial direction from the center, mouths of these swollen portions are closed, and the tip ends of respective swollen portions are in contact with the inner surface of an outer tube. | 10-16-2008 |
