Total Claims: 2
Claim 1
Independent Claim
125 words
A STIMULUS GENERATOR COMPRISING (A) A MULTIVIBRATOR RESPONSIVE TO TRIGGER PULSES FOR PRODUCING A SQUARE WAVE SYNCHROUNOUS WITH SAID TRIGGER PULSES WHICH ARE APPLIED THERETO, (B) INTEGRATING MEANS COUPLED TO SAID MULTIVIBRATOR FOR GENERATING A TRIANGULAR WAVE IN SYNCHRONISM WITH SAID SQUARE WAVE, (C) HIGH LEVEL DETECTOR MEANS INCLUDING A TUNNEL DIODE COUPLED TO SAID INTEGRATING MEANS FOR GENERATING SAID TRIGGER PULSES IN RESPONSE TO A PREDETERMINED POSITIVE LEVEL OF SAID TRIANGULAR WAVE, (D) LOW LEVEL DETECTOR MEANS INCLUDING A TUNNEL DIODE COUPLED TO SAID INTEGRATING MEANS FOR GENERATING ANOTHER ONE OF SAID TRIGGER PULSES IN RESPONSE TO A PREDETERMINED NEGATIVE LEVEL OF SAID TRIANGULAR WAVE, AND (E) MEANS FOR APPLYING SAID TRIGGER PULSES TO SAID MULTIVIBRATOR TO CONTROL THE FREQUENCY OF SAID SQUARE WAVE.
