Title: Data interpolation method
Inventor: GOTO YOSHIHIRO
IPC: G06F17/17
Filed: 1986-03-14
Abstract: PURPOSE:To attain the data interpolation by obtaining the number of known points around an unknown point and selecting the size of a section which limits the data on those known points set around the unknown point for interpolation as well as the type of an interpolation coefficient from the number of said known points to obtain the data on the unknown point. CONSTITUTION:The number Ci of known points ki of the data set around an unknown point X1 are obtained on a plane 200 where plural data are scattered. The value of the Ci is compared with the value of a constant set previously and properly. For the unknown picture element X1, Ci < constant I(0<1) is satisfied with Ci=0 to obtain the size of a section that limits the data on those known picture elements ki set around the X1 and used for interpolation, e.g., a size of (5X5) picture elements. Then a correction coefficient f1(r) is decided just by a distance (r) between those picture elements X1 and ki. The data on the X1 are decided by an equation as long as the f1(r) is selected as a large section interpolation coefficient. Thus the density data on the X1 can be estimated by interpolation even in case both elements X1 and ki are scattered irregularly. Then the data interpolation is possible.

Abstract: PURPOSE: To make the butt part of a rather thick-walled pipe in a deep position weldable from the inner side by providing pipes or holes conducting a shielding gas supplied from the pipe end to support rings.  
     CONSTITUTION: The size from the center of the weld zone up to the surface side of a pipe plate 2 is measured and the positions of a tungsten electrode 19, and a filler  wire guide pipe 22 are determined in conformity with this size. A torch body 12 is  placed on the end face of the pipe plate 2, and a locating pipe 13 is set in a hole 7  and a pipe part 2a. Welding is accomplished by generating the arc between the  electrode 19 and the part to be welded and supplying a shielding gas. Upon starting of welding, a filler wire 23 is supplied to the weld zone. The electrode 19 and  the wire 23 are moved along the weld zone by rotating support rings 15, 17, whereby welding is accomplished over the entire circumference of the butt part. As a rule, the welding is carried out in one rotation, but this mechanism permits multipass welding as well.
