摘要： A method for forming a flange at an open end of a pipe comprises increasing the diameter of the open end of the pipe to form a radially-enlarged pipe wall. Radially-symmetric portions of the radially-enlarged pipe wall are then removed so as to form at least two opposing projecting portions, which are then bent outwardly so as to be at least substantially orthogonal to the pipe, thereby forming the flange on the pipe.

摘要： Basalt filament is manufactured in such a manner that the fiber diameter can be controlled and the filament is not severed during the winding step. A network former and a glass modifier are formed and maintained with respect to basalt rock ore, and the crystallization and binding of basalt fiber are inhibited, the heat-resistance property of basalt fiber is greatly improved from the conventional 750° C. to 850 or 900° C., and significant cost reduction is achieved over conventional products. The method includes the steps of: grinding basalt rock as a material; washing a resultant ground rock; melting the ground rock that has been washed; transforming a molten product into fiber; and drawing the fiber in an aligned manner, and winding it. The temperature of the molten product in the melting step is 1400 to 1650° C., and log η is 2.15 to 2.35 dPa·s and preferably 2.2 to 2.3 dPa·s, where η is the viscosity of the molten product.

摘要： Anchor pieces (1A, 1B) made of elongated metal plates (11) detachably contact each other to form an anchor (H) for a reinforcing bar (Rb) made of fiber-reinforced plastic to be used in prestressed concrete. Elongated holes (12) respectively extend in a width direction of each of anchor pieces at regular intervals in a longitudinal direction thereof. At least one locking half portion (13) is formed in each anchor piece by deforming an area (Y) between adjacent elongated holes and has a convex semicircular shape or quarter sphere shell shape. At least one annular locking portion (14) is formed by the at least one locking half portion of the two anchor pieces when the two anchor pieces are in contact with each other. The annular locking portion has a circular inner space in transverse cross-section and is configured to engage the reinforcing bar (Rb) when disposed therein.

The housing 2 forms a storage space 21 having a diameter larger than the diameter of the exhaust pipe 1 and connecting to the rear connection part 22. The connection part 22 is tapered toward the downstream exhaust pipe 12 and the diameter of the connection part 22 is gradually reduced and its opening is welded into the opening of the downstream exhaust pipe 12. And a cylindrical honeycomb catalyst carrier 3 is stored in the storage space 21 so that the outer surface of the catalyst carrier is in contact with the inner surface of the storage space 21. An expanded portion 23 having a diameter larger than the diameter of the storage space 21 is outwardly expanded from the outer circumference of the housing 2 and connectingly provided on the front face of the storage space 21. The diameter of the expanded portion 23 is gradually reduced toward the upstream exhaust pipe 11 and welded into the opening of the outer wall of the exhaust pipe 11.
