摘要： PURPOSE:To obtain a component for piping system having excellent productivity and low production cost by compressing both ends part of a large sized pipe from two opposing directions and by joining with inserting a small sized pipe to the inside of the both ends part. CONSTITUTION:A preliminary forming article is formed by placing a large sized pipe 2A on press bed and with the plastic working of compressing the both ends parts from opposing two directions by a press die serving also as electrode. A small sized pipe 8 inserting a core metal in its center is inserted to both ends parts of the preliminary forming article thereof and the both end parts are further pressurized with the press die serving also as electrode, which is also heated with electrification. Both materials of an insert 7 for joining and the small sized pipe 8 are diffused in short time at the interface between them and a shrinked pipe part 5A is formed with the joining of the interface between the small sized pipe 8 and large sized pipe 2A and the mutual large sized pipe 2A. The desired silencer 1A is thus obtd.

摘要： PURPOSE:To use a driving source only at the time of switching -on and-off, and to realize energy saving by providing an elastic jump type diaphragm and turning on and off a punch, in a punching die consisting of plural punches and dies. CONSTITUTION:The center part of a springy metallic thin plate formed by a press to a projecting shape, elastic jump type diaphragms 1, 1' brazed to a metallic ring 2 are embedded between plates 6, 7 having a vent hole under a die set 5, dies 12, 12' embedded in a die plate 11 on a die set 10 are opposed to punched 3, 3', and a punching die is constituted. Subsequently, for instance, pressures P, P' are applied, and in a state that the diaphragms 1, 1' are deformed so as to be projectd downward and upward, respectively, through springs 4, 4', drilling by the punch 3 is executed to a thin plate 13. In this way, a driving source is used only at the time of switching -on and-off of the punch, and drilling of energy saving type can be executed.

摘要： PURPOSE:To form creases of desired size in a part of bandlike edge in the direction of width by rolling the edge of a band plate in the direction of width and generating a part in which distortion in the direction of rolling changes suddenly. CONSTITUTION:Two rolls 4A that can roll both edges of a band plate 1 by rolling parts 4a are provided in parallel on both sides of the band plate 1. The band plate 1 is sent in the direction of arrow and both edges are rolled by rolling parts 4a of rolls 4A, and sudden change is generated in distorsion in the direction of rolling along the width of the band plate 1. By this way a formed product 3A having crease 2 can be formed. By controlling the amount of sudden change controlling rolling down force, creases 2 of desired size can be formed.

摘要： PROBLEM TO BE SOLVED: To provide a tread board of a passenger conveyer and the passenger conveyer capable of improving durability of a cleat and comb teeth while securing safety and a good appearance by suppressing exposure of a side end surface.
SOLUTION: The passenger conveyer is provided with frame bodies installed on a building structure, landing floors arranged in a longitudinal direction of the frame bodies, and a plurality of the tread boards for circulating and moving between these landing floors. The tread board is provided with a cleat board with a line shaped cleat formed so as to have a square wave shape in cross section. An end part of the cleat in a line direction is provided with a curved surface which is curved so that end surfaces of the two side surfaces face oppositely.

摘要： PROBLEM TO BE SOLVED: To form a large number of viaholes at a high speed, in a piercing apparatus forming a large number of through-holes to a sheet like work by a punching mold and a means positioning the work, by arranging cam just above the punch of the punching mold. SOLUTION: A punch 1 and a shaft 7 are freely movable in an axial direction and a can follower roller 6 is always pressed to the cylindrical surface of a cam 10 by a coil spring 2. When the cam 10 is rotated and the cam follower roller 6 comes into contact with the part having a large radius of the cam 10, the punch 1 falls to perform the viahole processing of a green sheet 4. During a period when the cam follower roller 6 is contact with the part having a small radius of the cam 10, the lower end of the punch 1 is present above the rear surface of a punch holder 3 and this position is set to the top dead center of the punch to perform the movement and positioning of the green sheet 4. At each time when the cam 10 makes one revolution, the up and down movement of the punch 1 and the movement and positioning of the green sheet 4 are alternately performed.
