IPC: G05B11/36
Filed: 1981-05-13
Abstract: PURPOSE:To make an output constant optionally during its variation, by cutting off the input side of an integral network when gradually varying the output by the integral metwork even if an input varies stepwise. CONSTITUTION:An arithmetic means 1 finds a difference between an input signal Vi and the output signal V0 of a trailing integrating means 2. This difference voltage is inputted to an integrating means 2 through a unidirectional conducting means composed of diodes D1 and D2. The diode D1 conducts when the output signal of the arithmetic means 1 is negative and the diode D2 conducts when positive, thereby decreasing and increasing the output of the integrating means 2 gradually and respectively. To make the output, decreased gradually, constant at an optional level, a base signal is supplied to a transistor TR1. As a result, the TR1 turns on to cut off the diode D1, so that the variation of the output stops.
