oscillating mechanical device with piezoelectric excitation and its application to the activation of a laser gyro.

摘要

The device according to the invention comprises two elements (9,10) OSCILATING placed one relative to the other through at least one sheet ELASTICA (19) on which is fixed a piezoelectric ceramic (24). LEVEL OF YOUR UNION WITH THE ELEMENT (9), ONE OF THE TWO SIDES (20) of the sheet (19) is extended WITH RESPECT TO THE OTHER SIDE, thanks to a prolongation formed on said element (9). CERAMICS (24) is thus fixed on the sheet (19), SO THAT SERVE ON SUPPORT prolongation. The invention allows SPECIAL INCREASE EFFICIENCY OF CERAMICS USED FOR ACTIVATION OF LASER gyros and reduce their number.
