Diode-capacitor charge and discharge circuit
Abstract
Abstract A HIGHLY SENSITIVE AND COMPLETELY STABLE CIRCUIT FOR AND METHOD OF DETECTING LOW AMPLITUDE, SHORT DURATION DIRECT CURRENT SIGNAL VARIATIONS ASSOCIATED WITH SPARKING BETWEEN AN ELECTRODE TOOL AND A CONDUCTING WORKPIECE IN AN ELECTROCHEMICAL MACHINING PROCESS OR THE LIKE AND SUBSTANTIALLY IMMEDIATELY PRODUCING A CONTROL SIGNAL IN RESPONSE TO A PREDETERMINED DETECTED SIGNAL LEVEL IS DISCLOSED. THE STRUCTURE INCLUDES A POLARITY DISCRIMINATING SENSING CIRCUIT FOR INITIALLY DETECTING THE SIGNAL VARIATIONS, AN AMPLIFIER CIRCUIT FOR PROVIDING AN AMPLIFIED AND STABILIZED SIGNAL SUBSTANTIALLY IMMEDIATELY ON SENSING A SIGNAL VARIATION OF THE PROPER POLARITY AND OUTPUT CIRCUIT FOR PROVIDING AN OUTPUT SIGNAL IN RESPONSE TO A SELECTED PORTION OF THE AMPLIFIED AND STABILIZED SIGNAL, INCLUDING MEANS FOR SELECTING THE LEVEL OF THE SELECTED SIGNAL PORTION OPERABLE TO PROVIDE THE OUTPUT SIGNAL, MEANS FOR CUTTING OFF THE AMPLIFIED AND STABILIZED SIGNAL WHEN THE SELECTED LEVEL IS BELOW A PREDETERMINED MINIMUM AND MEANS RESPONSIVE TO A NUMBER OF AMPLIFIED AND STABILIZED SIGNALS, WHICH HAVE A LEVEL BELOW THE SELECTED LEVEL RECEIVED IN A PREDETERMINED TIME FOR PROVIDING AN OUTPUT SIGNAL.
