Title: Manufacture of extremely thick-wall seam welded steel tube
Inventor: SUMIMOTO DAIGO
IPC: B21C37/08
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a steel tube minimizing thickness deviation by using a plug having a taper angle which is smaller by 1-5 deg. than the taper angle (half angle) of a die in the manufacture of an extremely thick-wall seam welded steel tube in which its diameter is reduced and its wall is thickened by thrusting the plug. SOLUTION: One or several spherical punches are rotated around a die 1, a tube 4 is thrusted by also rotating the die 1 around the tube 4 in the opposite direction to the punches and, by striking the tube 4, the diameter is reduced and the wall is thickened. An important matter is the taper angle β of a tapered plug 8 used, it is not whole angle but the angle of one side, i.e., it means a half angle and is made smaller by 1-5 deg. than the taper angle (half angle) α. When the decreasing angle is less than 1 deg., the taper angle α of the die 1 is approximatelly coincident with the taper angle β of the tapered plug 8, so restraining effect to the tube 4 is eliminated and, when it is over 5 deg. and if the taper angle α of the die 1 is small, the taper angle β is made approximately straight and the plug can not be pulled out.  In this way, the thick-wall seam welded steel tube minimized thickness deviation can be produced.

Title: Machine translation system reusing dictionary information
Inventor: NISHIMURA MASAYA
IPC: G06F17/27
Filed: 1991-03-15
Abstract: PURPOSE:To use the information for following translation again by preserving the dictionary information of a once translated sentence. CONSTITUTION:At the machine translation device, an enough translated result can not be obtained by one time of translation frequently. In order to this point, the quality of translation is improved by adding information and executing translation again while manually executing correction (pre-edition) after the translation is executed once. In this invention, the dictionary information of the once translated sentence is preserved for the unit of a word and used for the following translation again. Only when the word is corrected in the pre- edition, a dictionary is referred to, and the reference of the dictionary is suppressed at a minimum so as to accelerate the translation.
