Abstract

PURPOSE:To make actual gain infinite and enable stable work by using an integrated circuit instead of an operational amplification circuit. CONSTITUTION:Since error voltage Ee becomes a large value to some extent at the transient period of time which does not arrive at stationary working state, the output voltage from the nonlinear amplifier 13 becomes an extremely large value and instantaneously charges the integrating capacitor 12, thereby making the table feeding speed constant. When the working state enters the stationary state, the average value of the error voltage Ee over a certain period of time becomes zero, but instantaneously small voltage variation occurs due to external disturbance. In this case, however, the output voltage of the nonlinear amplification circuit 13 becomes an extremely small value. The change of the integrated value becomes very small and the feeding speed is thus stabilized.
