Claim 1
Independent Claim
203 words
IN AN ELECTRONIC WATCH, A BALANCE PIVOTABLY CONNECTED FOR OSCILLATING ABOUT A GIVEN AXIS, A PERMANENT MAGNET DISPOSED ON SAID BALANCE AND HAVING A MAGNETIC AXIS PARALLEL TO SAID GIVEN AXIS, A DRIVE COIL AND A CONTROL COIL COAXIALLY DISPLACED FROM EACH OTHER AND SO DISPOSED THAT SAID PERMANENT MAGNET PASSES BETWEEN SAID COILS WITH THE MAGNETIC AXIS BEING PARALLEL TO THE COMMON AXIS OF SAID COILS, A TRANSISTOR AMPLIFYING MEANS INCLUDING AT LEAST A BASE, AN EMITTER AND A COLLECTOR, A SOURCE OF VOLTAGE HAVING A FIRST TERMINAL CONNECTED TO SAID EMITTER AND A SECOND TERMINAL, MEANS FOR CONNECTING SAID DRIVE COIL BETWEEN SAID SECOND TERMINAL AND SAID COLLECTOR, MEANS FOR CONNECTING SAID CONTROL COIL BETWEEN SAID EMITTER AND SAID BASE, WHEREBY MAGNETIC FIELDS ARE GENERATED BY SAID COILS, MEANS ASSOCIATED WITH SAID BALANCE FOR CAUSING SAID BALANCE TO HAVE A REST STATE WHEREIN SAID MAGNETIC AXIS IS DISPLACED FROM THE COMMON AXIS OF SAID COILS AND SAID PERMANENT MAGNET IS UNDER THE INFLUENCE OF THE MAGNETIC FIELDS GENERATED BY SAID COILS, AND MEANS FOR APPLYING A VOLTAGE TO THE BASE OF SAID TRANSISTOR AMPLIFYING MEANS FOR TEMPORARILY INCREASING THE EMITTERCOLLECTOR CURRENT PASSING THROUGH SAID DRIVE COIL FOR STARTING SAID BALANCE OSCILLATING.
