Title: Method for forming pipe end connecting head in double rolled steel pipe
Inventor: USUI MASAYOSHI
IPC: B21D41/02
Filed: 1980-07-29
Abstract: PURPOSE: To easily form connecting heads of double rolled pipes which will not allow any leaking, by installing a plural number of parallel grooves along the outer circumference within a limited width at the end part of double rolled pipes, and then, by swelling out the parallel grooves to become a bridge.  
     CONSTITUTION: On the outer circumferential surface 1' at the straightened end part of a double rolled steel pipe 1 having a depressed part 8 at the rolled end margin, a plural number of parallel grooves 2 which have a saw-toothed cross section and which are parallel to the direction of circumference of the pipe, are installed within the area having a relatively narrow width with a rotary edge member 5. Then, the pipe 1 is fixed by a chuck 6 and a bridge-shaped swelled out head part in which the parallel grooved part 2 becomes a pushing seat face 3, is formed at the end of the pipe, by pushing the pipe 1 from the outside of the end with a punching member 7. In this way, because the depressed part 8 at the seat face 3 is cut into pieces bythe parallel grooves 2 and, at the same time, the depressed part 8 will be crushed by the saw-toothed face when this pipe is connected to another pipe by means of screw, a pipe connection which will not allow any leaking from the depressed part 8 can be performed.

Filed: 1984-05-25
Abstract: PURPOSE:To heat only wafers efficiently by a method wherein heaters are provided behind wafer holders and the heaters and the holders are shielded by a shield plate which also serves as a reflective plate. CONSTITUTION:A wafer holder part is formed with jointing members 2 composed of quartz plates 1, stainless steel and the like into an annular shape. Lamp heaters 3 and a shield plate 4 which also serves as a reflective plate are attached behind the wafer holders. The shield plate 4 is composed of a heat resistant metal plate which is bent to have a parabolic cross section and reflects thermic rays from the heaters 3 onto the wafers and at the same time protects the heaters from adhesion of evaporated substances. With such apparatus, as the wafers 5 put on the holder part 1 are heated by the heaters 3 from back of the holder part 1, mingling of harmful decomposed gases and deterioration of the vacuum rate by the evaporated substance due to the irradiation of the thermic rays into a vacuum chamber are eliminated. Moreover, uniform heating at the constant temperature is facilitated.

Abstract: PURPOSE:To surely execute a magnetic sorting operation by a method wherein an element-part formation region and a non-chip part are isolated by a stepped part and a film is formed on a rod-like substrate piece only in the element-part formation region in order to clearly divide a chip part and the non-chip part. CONSTITUTION:Before an insulating base material is baked, through parts 24 which are wider than dividing grooves 21, 22 are made in non-chip parts 26, 27 at end parts in the longitudinal direction of substrate pieces 25; after the base material has been baked, it is divided into the substrate pieces 25; an element-part formation region 29 in the center of each substrate piece becomes wider than the non-chip parts 26, 27 on both ends. The non-chip parts 26, 27 are supported; an end edge face on one side of the substrate piece is brought into contact with an electrode-material coating face of a coating roller 8; since stepped parts are formed between the element-part formation region 29 and the non-chip parts 26, 27, only the element-part formation region 29 comes into contact with the roller face 8; it is possible to prevent the non- chip parts 26, 27 from being coated. By this setup, it is possible to surely isolate and sort a chip component as a good product from a non-chip component in a magnetic sorting process which is based on the existence of an electrode film.
