IPC: G04F10/04
Filed: 1985-08-20
Abstract: PURPOSE:To achieve a higher resolution using a low frequency clock pulse, by integrating the number of clock pulses about several events to determine the mean, based on which the continuation time of the events is determined. CONSTITUTION:The output Q of an FF7 moves to a H level at each event and an AND gate 10 is opened to transmit a clock pulse phase operated with a phase shifter 9 to a terminal IN of a counter 11. The number of clock pulses is integrated for N events and upon the end of the Nth events, the integrated values are outputted to the output terminal OUT. The total number of clock pulses integrated for N events is inputted into a divider 12 to determine the number of clock pulses per event by dividing it by N. The continuation time of the events correspond to the value obtained by multiplying the mean by the cycle of the clock pulse thereby improving the resolution of the event continuation time N times.

Abstract: PURPOSE:To decrease the number of unknown elements by providing a feature point integrating part to delete the unknown elements of short length which are decided undesired among those line pattern description elements existing among line pattern description elements of straight lines, circles and circular arcs and then integrating the feature points. CONSTITUTION:The feature points n1-n9 are set on a line pattern together with the straight line elements l1-l6 and unknown elements u1 and u2 respectively. The two straight line elements are evaluated according to the length of the foot of a vertical line drawn down to a straight line (inverses of n8n4 and n4n6) that may be produced when those straight line elements are integrated. Then two straight line elements (l3/l4 and l5/l6) are integrated for the production of straight line elements l3' and l5'. An extracting part 3 extracts (l2 and l5') the combination of two straight line elements to be integrated at a branching point where 3 straight line elements are connected to each end point by the connecting angle of two straight line elements. Thus the possibility of integration is evaluated for two straight line elements according to the length of the foot of a vertical line drawn down to a straight line (inverse of n3n6) that may be produced when those two straight line elements are integrated at a branching point (n4).
