Claim 1
Independent Claim
207 words
IN A LIGHT RADIATION RESPONSIVE FERROELECTRIC POLARIZ ING MEANS: (A) PHOTOCONDUCTOR MATERIAL PRESENTING FIRST AND SECOND TERMINALS; (B) FERROELECTRIC MATERIAL PRESENTING FIRST AND SECOND SURFACES AND SAID SECOND SURFACE ELECTRICALLY COUPLES TO SAID SECOND TERMINAL; (C) LIGHT RADIATION CONDUCTOR MEANS FOR SUPPORTING SAID PHOTOCONDUCTOR AND FERROELECTRIC MATERIALS AND CONTROLLING THE REFLECTION OF LIGHT RADIATION TO SAID PHOTOCONDUCTOR MATERIAL; (D) A FIRST SOURCE OF VOLTAGE FOR PROVIDING A FIRST VOLTAGE POLARITY; (E) MEANS FOR CONNECTING SAID VOLTAGE POLARITY OF SAID SOURCE BETWEEN SAID FIRST TERMINAL AND SAID FIR SURFACE AND, UPON A REFLECTION OF LIGHT THROUGH SAID CONDUCTOR MEANS TO WHICH SAID PHOTOCONDUCTOR MATERIAL IS RESPONSIVE, EXTENDING SAID VOLTAGE POLARITY OF SAID SOURCE BETWEEN SAID FIRST AND SECOND SURFACES TO ESTABLISH POLARIZED EFFECTS IN SAID FERROELECTRIC MATERIAL; (F) A SECOND SOURCE OF VOLTAGE FOR PROVIDING A SECOND VOLTAGE POLARITY; AND (G) MEANS FOR DISCONNECTING SAID FIRST VOLTAGE POLARITY OF SAID SOURCE, CONNECTING SAID SECOND VOLTAGE POLARITY OF SAID SECOND SOURCE BETWEEN SAID FIRST TERMINAL AND SAID FIRST SURFACE AND, UPON THE EXPOSURE OF SAID PHOTOCONDUCTOR MATERIAL TO LIGHT RADIATION TO WHICH IT IS RESPONSIVE, EXTENDING SAID SECOND VOLTAGE POLARITY OF SAID SECOND SOURCE BETWEEN SAID FIRST AND SECOND SURFACES TO DISESTABLISH SAID POLARIZED EFFECTS IN SAID FERROELECTRIC MATERIAL.
