<p>PURPOSE:To attain ease of adjusting work and also to decrease a skew due to delay by consitituting the system that the phase of a clock signal and a stop signal is adjusted entirely within the machine cycle. CONSTITUTION:Although a true difference between two clock signals a, b is TD1, since the phase adjustment of TD2 is enough actually, the phase adjusting range of variable delay circuits 15-17 is smaller than the machine cycle time tau. Moreover, a phase difference TD3 between two stop signals c, d is separated into the two units of machine cycle time 2tau and a TD4 smaller than the tau, and in adjusting the phase difference 2tau by shift register 22 driven by the clock, the phase adjusting range of variable delay circuits 23-25 is decreased less than the machine cycle time tau.</p> |
