Title: Timing pulse controller
Inventor: AWAYA ICHIRO
IPC: H03K5/15
Filed: 1993-01-11
Abstract: PURPOSE:To form new pulse strings at equal intervals only by remaining pulse generating parts or CPUs even when several pulse generating parts or CPUs break down. CONSTITUTION:Each oscillator 121-12N connected in a loop searches for a phase difference between the oscillation phase of its own device and the oscillation phase of the oscillator at the succeeding stage, and also searches for a difference between the phase difference and the phase difference obtained by the oscillator at the preceding state. Moreover, each of oscillators 121-12N operates so that the difference of the oscillation phase difference is converged to '0'. Timing pulse control parts 131-13N output pulse output command signals to pulse generating parts 141-14N when the oscillation phases of the corresponding oscillators 121-12N are 0 deg.. The pulse generating parts 141-14N generate the pulses at equal intervals according to the commands from the timing pulse control parts 131-13N. Thus, even when the timing of the pulse generation is shifted due to a fault, a new loop except defective system is formed, and the pulses are outputted at equal intervals.
