Filed: 1983-11-24
Abstract: PURPOSE:To detect data correctly regardless of insertion position dislocation of data format without using a complex circuit by transferring a reference signal by adding it to a data signal from a transferring side and by computing a sampling point of the data signal from the reference signal on a receiving side. CONSTITUTION:A multiple part 1 on the transmitting side overlaps the data signal and the reference signals ''1'' and ''0'' between vertical synchronizing blanking sections and sends them out. The reference signals are overlapped in the same frequency as the data signals at front of the data signals. In the receiving section a clock generation circuit 4 synchronizes with a horizontal synchronizing signal M to make a reference clock L. A pattern detection circuit 3 detects levels of the reference signal and data signals, and a stable area setting circuit 7-1 detects the front ''H'' of the detected results and sets the ''H'' level area. At the same time, the number of clock L in the area is counted and ''n'' of counted results decides a stable area of the reference signal. An arithmetic circuit 7-2 operates a central reference position of said area by the signal denoting the area. A timing generation circuit 7-3 sends out data signal extraction timing D to a data extraction circuit 5 by said position signal.

Title: Circular interpolation method for x-y table
Inventor: OSHIMA HIROSHI
IPC: G05B19/404
Filed: 1988-08-31
Abstract: PURPOSE:To extremely improve the locus accuracy with correction of the distortion of a circular track by correcting the phase delay amount without deteriorating the loop gain. CONSTITUTION:The characteristics 11 and 12 of a phase angle PHI are previously measured against an angle frequency omega, and a phase difference DELTAPHI10 between the X and Y axes is obtained and stored in a memory 2. The phase difference DELTAPHIis set to the target angle frequency omega, and the target track phase of the X axis is outputted relatively with a delay equal to the difference DELTAPHI to the target track of the Y axis. Thus the actual synchronization of actual track phases is secured between both aces. Then the difference between the target circular track 41 and a locus 45 is reduced and the locus accuracy is extremely improved. It is actually impossible to advance the phase of the target track of the Y axis based on a time base. Therefore the phase of the target value of the X axis is relatively delayed to that the phase difference is corrected.
