Claim 1
Independent Claim
137 words
THE METHOD OF FABRICATING A FUSTRATED INTERNAL REFLEXTION RADIATION MODULATION DEVICE WHICH HAS FIRST AND SECOND REFRACTING ELEMENTS AND A PIEZO-ELECTRIC DEVICE FOR DETERMINING THE SEPARATION THEREBETWEEN, COMPRISING THE STEPS OF (A) ATTACHING SAID FIRST REFRACTING ELEMENT AND THE PIEZO-ELECTRIC DEVICE TO A BASE ELEMENT AND THE SECOND REFRACTING ELEMENT ON A SUPPORT MEMBER, (B) SPREADING AN EPOXY LAYER ON THE PIEZO-ELECTRIC DEVICE, (C) PLACING THE SECOND REFRACTING ELEMENT ON SAID FIRST REFRACTING ELEMENT SO THAT THE SECOND REFRACTING ELEMENT IS SUPPORTED BY THE FIRST REFRACTING ELEMENT WITH THE EPOXY LAYER SEPARATING SAID PIEZO-ELECTRIC DEVICE AND SAID SUPPOT MEMBER, AND (D) CURING SAID EPOXY LAYER BY HEATING THE MODULATION DEVICE AND APPLYING A VOLTAGE TO SAID PIZEOELECTRIC DEVICE TO EXPAND THE PIEZO-ELECTRIC DEVICE BY AN AMOUNT NECESSARY TO LEAVE THE DESIRED SEPARATION WHEN THE VOLTAGE IS REMOVED.
