Abstract: PURPOSE:To shorten the time required for line changeover by setting a public line in advance before the quality of a private line is deteriorated and the communication is disabled in a MODEM having the private line and the public line and selecting the public line just after the communication is disabled by the private line. CONSTITUTION:A quality measurement section 11 of a private line 3 of a MO DEM 1 always measures the quality of a private line 3 and a signal from the quality measurement section 11 is used for a control section 8 to control a network control section 10 when the quality of the private line 3 is deteriorated more than a preset reference value and the section 11 makes a call to a MO DEM 2 via a public line 4. When a network control section 15 in the MODEM 2 receives the call, the public lines 4, 6 are connected via an exchange network 5. When the quality of the private line 3 is further deteriorated, the control section 8 controls a line switching section 9 to select the line from the private line 3 into the public line 4 and the control section 13 controls similarly the line switching section 14 to select the public line 6. Thus, the time required for the line switching is shortened.

Title: Method for detecting correction quantity, method for correcting distortion and its device
Inventor: MIZUGUCHI DAIZO
IPC: B21D3/10
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain an efficient and highly precise method for detecting correction quantity by calculating a distance from a target line at each correcting point, determining anabolic a correcting quantity at each correcting point from a relation between a virtual and the prescribed target lines, and thereby shortening time for correction. SOLUTION: Displacement differences, d'(i), d"(i) and d'(i+1), d"(i+1), are determined which are from a target line at both ends of the correcting span of a work after correction. These displacement differences are reflected in the work shape X(K) before correction, so that a virtual target line A-B-C-D is determined. The work shape X'(K) after correction is determined by coinciding with the target line. For this purpose, on the basis of a calculation expression, the correction quantity is computed at each correcting point, P(i), P(i+1). The correction quantity D(i) at the point P(i) is D(i)=V(i)×W÷[4×P(i)], where V(i)=X'(i)+[X' (i+1)-X'(i)]÷[P(i+1)-P(i)], assuming W is the correcting span. Thus, the correction quantity is determined.
