Title: Manufacture of t-pipe joint made of steel plate
Inventor: KOJIMA MASAYASU
IPC: B21D19/08
Filed: 1981-09-26
Abstract: PURPOSE:To exactly prevent the pipe end of a branch pipe part from becoming irregular, and also to save the number of times of burring, by formed a bulge part whose top is flat and trapezoidal, when forming a branch pipe of a T-pipe joint. CONSTITUTION:A blank steel plate 6 is placed on a die 7, and a U-bend punch 9 is dropped. As for the U-bend punch 9 to be used, a plug 9' is installed to a position opposed to a die branch pipe hole 12, of a semicylindrical bottom surface 8 having the same curvature as the inside surface of a base pipe part 1 of a branch pipe side piece. When the punch 9 drops, the blank steel plate 6 is curved, and a bulge part 18' whose top is flat is formed. A reduced portion by this bulge working concentrates in a bent deformation part which is in contact  with a shoulder part 8'' of the plug 9', a reduced portion of a material contacting with a flat bottom surface 8' of the plug 9' is extremely small, and on the  top of the bulge part 18', no biased portion is formed. Subsequently, by a conventional method, a lower hole 11 is opened in the center of the bulge part 18',  and after that, a branch pipe part is formed by burring working.

IPC: F28D15/04
Filed: 1983-08-22
Abstract: PURPOSE:To transport heat over long distances as well as to lessen the loss of pressure of working fluid by closly attaching a wick made of the bundle of vertically aligned plural extremely fine filaments along the axial direction of an enclosed tube to the inner surface of the enclosed tube. CONSTITUTION:In a heat pipe 1, a wick 4 made of the bundle 3 of plural extremely fine filaments is set on the inner surface of an enclosed tube 2 and closely adhered to the inner surface by a presser tool 5 inserted into the tube 2. A working fluid is confined in the tube 2. In the wick 4, many filament bundles 3 are integrally interwoven with filling weft 6. In the heat pipe, the inside of the filament bundles 3 and the apertures formed between the filament bundles 3 serve as a refluxing path for the liquid phase working fluid. Since the refluxing path is in straight line along the original flowing direction of the working fluid, a heat pipe having smaller flowing resistance for the liquid phase working fluid can be obtained.

Abstract: PURPOSE:To control generation of cutouts by reducing tensile force into a mold, by a method wherein premolding is performed by setting a mat material to a molding tool having larger mold clearance than a thickness of a base material by keeping a fleecy state of the mat material as it is. CONSTITUTION:A fleecy mat FM is obtained by spraying raw materials obtained by mixing a binder (for example, polyethylene) with main raw materials composed of woody pulp, hemp, cotton and a chemical fiber at a predetermined rate over carrying conveyors 7, 8 by a turnable outturun machine 6 by putting in two about equally on both sides by a quantitative supply machine 5 constituted of a pair of conveyors. Then the mat FM is made into a fleecy mat material MS by piling up the same on the mat FM, which is being conveyed away by the other conveyor 8, by a piling conveyor 9. The same is premolded by keeping a fleecy state of the same as it is. A mold whose clearance has been established at 2-6 times (5-15mm) as thick as a thickness of a base material is used for the mold to be used hereupon. With this construction, tensile force in the inside of the mold is reduced also and, therefore, generation of cutouts is prevented.
