Title: Input signal holding and switching device
Inventor: HAMAZAKI HIROMICHI
IPC: G05B7/02
Filed: 1982-10-07
Abstract: PURPOSE:To realize a signal holding and switching device, in which external disturbance produced at switching is eliminated by providing a circuit which outputs a signal seemed to be safer or other signal changed suddenly, when one of duplicated signals are changed rapidly. CONSTITUTION:When an input e1 is increased rapidly while an input e3 is increased in following to an input e2, the e3 follows the e2 independently of the rapid change in the e1. The e2 is outputted as an output V0. On the contrary, when the e1 is decreased rapidly, the e3 is outputted as the output V0. The e3 in this case holds a value at rapid change. On the other hand, since an alarm is generated from a deviation monitor 4, the operator repairs a failure of any signal system. Since the output V0 is held to a constant value during this time, no external disturbance is given to this system.
