Filed: 1979-09-11
Abstract: PURPOSE: To make the handling easy, and to attain the sufficient shape accuracy, by taking the influence of the distortion and the roll radius deviation into the arithmetic formula for carrying out the shape control.  
     CONSTITUTION: When the shape controlled rolling work is to be carried out by a little skewed backup rolls contacting the work rolls taking the middle of the work roll as the skewing center, the synthesized crown of the rolls' contact part, obtained by synthesizing both rolls' distortions and radius deviations, is expressed as the even function of the distance x in the axial direction from the center of the skew. For the computing program, the coefficient of each term is taken in as a part of inputs of the electronic computer, and the correlation coefficient between the skew angle and the load for giving the bending to the roll is computed so as to make the curvature of the middle of the work roll to be the expected value. Taking this correlation coefficient as the reference value, the control unit is controlled.

Title: Border line extracting system
Inventor: SHIONOYA HIROSHI
IPC: G06V10/46
Filed: 1981-07-24
Abstract: PURPOSE:To eliminate a noise part touching with a diagram when the tracing of the border line of the diagram is interrupted by the noise, by successively checking backward picture elements adjacent to the border points which have been traced. CONSTITUTION:In the course of the tracing of a border line, the center of the mask exists at a point (b). Since a point (c) is traced in the tracing process at the point (b) because the point (c) is nearer to the past tracing direction (a)-(b) than a point (d) on the border line, interruption of the tracing takes place due to a noise N touching with the border line F. In this case, picture elements touching with the border points which have been traced are successively checked backward. When the backward check reaches a picture element (b) at a branching point of the border part F and the noise part N, a picture element which is to be traced next is retrieved by using the picture element (b) as the mask center and a picture element (d) consisting the border line is found as the picture element to be traced next. Then, the tracing is countinued by using the picture element (b) as the mask center.
