20100037658 | VEHICULAR UPHOLSTERY POLYPROPYLENETEREPHTHALATE FIBER FABRIC AND METHOD FOR PRODUCING OF FABRIC - A vehicular upholstery fabric is made from a raw tricot fabric which is knitted by using a PPT-multifilament yarn whose single fiber fineness is about 0.5˜6.0 dtex and whose total fineness is about 30˜180 dtex for the ground yarn and the pile yarn. The raw tricot fabric has been transformed into a napped tricot pile fabric by raising the sinker loop of the pile yarn of the raw tricot fabric to form fluffs which are then sheared to form cut piles. A PPT-bulky multifilament yarn is used for the ground yarn. A PPT-non-bulky texturized multifilament yarn or a PPT-bulky texturized multifilament yarn is used for the pile yarn. | 02-18-2010 |
20100047538 | VEHICULAR UPHOLSTERY POLYPROPYLENETEREPHTHALATE FIBER WOVEN FABRIC - The present invention teaches a_vehicular upholstery PPT-fiber fabric that is formed from a double woven fabric in which a face weaving textile design has a number of intersections, called warp up intersections where a warp yarn passes over a weft yarn, and these are more than the number of intersections, called weft up intersection, where a weft yarn passes over a warp yarn. The warp yarn is formed by twisting an intermingled yarn composed of a PPT-multi-filament yarn and a high heat shrinkable PET-multifilament yarn whose shrinkage percentage in boiling water is more than 15%. An intermingle ratio of the PPT-multifilament yarn of the warp yarn is more than the intermingle ratio of the PET-multifilament yarn of the warp yarn. In the warp yarn, the PET-multifilament yarn is shrunk by heating, so that the substantial length of the PET-multifilament yarn becomes shorter than the substantial length of the PPT-multifilament yarn. The weft yarn is composed of PPT-multifilament yarn. | 02-25-2010 |
20100227109 | VEHICULAR UPHOLSTERY POLYPROPYLENETEREPHTHALATE FIBER FABRIC - Vehicular upholstery fabric is woven by using chenille yarn and multi-fiber yarn for weft yarns. The weaving interval between chenille yarns is set up less than the apparent thickness of the chenille yarn, which is specified as an observed value of the thickness. The apparent thickness of the multi-fiber yarn is less than one-fifth of the apparent thickness of the chenille yarn. There are tight portions where a great number of warp yarns passes over the chenille yarn, and rough portions, where a small number of warp yarns passes over the chenille yarn that is formed on the surface of fabric. PPT-fibers are used for the pile of the chenille yarn and the warp yarn. | 09-09-2010 |

20080237312 | Brazing method - In a brazing method, tubes for a heat exchanger, in which an inner fluid flows and exchanges heat with an outer fluid, are bonded to fins for expanding a heat exchange area at a time of exchanging the heat, by using a brazing material of paste form. The method includes a mounting step of stacking the tubes and the fins alternately in layers to form an assembly, a coating step of coating portions near outside abutting portions where the tubes abut on the fins with the brazing material after the mounting step, and a brazing step of carrying the assembly coated with the brazing material in the coating step into a brazing furnace and of brazing the tubes to the fins. | 10-02-2008 |
20090107658 | Metallic material for brazing, brazing method, and heat exchanger - A brazing method is provided for brazing a metallic material for brazing to another metallic material. The metallic material for brazing includes a base material portion made of copper or a copper alloy containing chrome by a predetermined amount, and a metallic film portion made of a material having a melting point lower than a heating temperature in brazing, and provided on the surface of the base material portion. The brazing method includes a step of assembling the metallic material for brazing and the another metallic material to form an assembly, a step of heating and brazing the assembly, in which the metallic film portion is melted to diffuse chrome into a surface of the metallic material for brazing, and a step of forming a chrome oxide film by using the chrome diffused into the surface of the metallic material for brazing in atmosphere after the brazing step. | 04-30-2009 |
20090133860 | Heat exchanger - In a heat exchanger, a tube is adapted to exchange heat between a first fluid flowing therein and a second fluid flowing through outside of the tube, and an inner fin is disposed in the tube to divide a flow passage in the tube into a plurality of flow paths. The inner fin includes a plurality of fin portions with different specifications, and the fin portions are arranged in series with respect to a flow direction of the first fluid. Furthermore, the fin portion with the smallest flowing resistance of the first fluid among the plurality of fin portions is arranged on an upstream side of the flow direction of the first fluid with respect to at least an another fin portion. Accordingly, heat exchange performance in the entire heat exchanger can be effectively improved. | 05-28-2009 |
20110168364 | Heat exchanger - In a heat exchanger with a plurality of tubes, a header tank includes a core plate bonded to the tubes, a tank body fixed to the core plate, and an elastic member arranged between a bottom portion of a groove portion provided at an outer peripheral portion of the core plate and a tip end portion of the tank body to be elastically deformable therebetween. The elastic member is provided with a position determination portion which protrudes approximately in parallel with an inner bottom surface of the bottom portion of the groove portion. Furthermore, the position determination portion is configured in the elastic member to have a clearance between the position determination portion and the bottom surface of the bottom portion of the groove portion, and a clearance between the position determination portion and the tip end portion of the tank body. | 07-14-2011 |
20110274958 | BATTERY PACK - A battery pack has multiple wall-shaped projecting portions, which are provided on side surfaces of battery cells perpendicular to a layer direction X, extend in a flow direction of cooling fluid and arranged in a direction perpendicular to the flow direction of the cooling fluid, to form fluid passages between neighboring battery cells. It further has multiple enlarged projecting portions, which are provided at intermediate portions of the wall-shaped projecting portions extending in the flow direction of the cooling fluid and brought into contact with the neighboring battery cells to receive action force therefrom. An outer dimension of the enlarged projecting portions in the direction, in which the multiple wall-shaped projecting portions are arranged, is made larger than a thickness dimension of the wall-shaped projecting portions. | 11-10-2011 |
