Abstract

PURPOSE:To secure the fail-safe properties, by using a storage device that shows the asymmetric mode of the side where both output voltages always contract in case when a trouble arises. CONSTITUTION:An AND element AL [ where (e) is the negative polarity input, (c) is the positive polarity output and (d) is the negative polarity output] having the fail-safe properties forms a steering circuit which delivers ST1, ST2 and ST3 in that order every time when the clock PC arrives. While an AND element LS' having the fail-safe properties forms a storage device which performs the self-supporting to reset the output when no input exists at a terminal (b). Accordingly, a counter that delivers the output successively from CV1 with every arrival of the clock CP in the normal state. However, an element having the fail-safe properties, if it has some trouble, delivers no output. As a result, the counting does not proceed any more.
