Abstract

Un disco mobile reggi-televisore poggia girevolmente su un fisso. Un settore presentante una faccia cilindrica di materiale ad alto coefficiente d'attrito, è calettato al disco mobile. Una sbarretta di materiale ad alto coefficiente d'attrito è disposta tangenzialmente a contatto colla faccia cilindrica del settore. Un attuatore piezoelettrico è disposto per spingere la piastrina in direzione tangenziale contro la reazione di mezzi elastici, mentre mezzi di spinta premono la sbarretta radialmente contro la faccia laterale del settore. Mezzi di controllo eccitano periodicamente l'attuatore piezoelettrico e attivano collo stesso periodo detti mezzi di spinta in fase o in controfase rispetto all'eccitazione dell'attuatore piezoelettirico, in modo da ottenere la rotazione del disco mobile concordemente o in opposizione rispetto alla spinta dell'attuatore piezoelettrico sulla sbarretta.A mobile TV-holding disk rotates on a fixed one. A sector having a cylindrical face of material with a high coefficient of friction is keyed to the mobile disc. A bar of material with a high coefficient of friction is arranged tangentially in contact with the cylindrical face of the sector. A piezoelectric actuator is arranged to push the plate tangentially against the reaction of elastic means, while pushing means press the bar radially against the side face of the sector. Control means periodically excite the piezoelectric actuator and activate in the same period said thrust means in phase or in counterphase with respect to the excitation of the piezoelectric actuator, so as to obtain the rotation of the mobile disc in accordance with or in opposition with respect to the thrust of the piezoelectric actuator on the bar.
