Oscillating mechanical device is an excitation piezoelectric, and its application to the activation of a gyroscope a laser

摘要

The device according to the invention comprises two elements 9, 10 mounted to oscillate relative to one another by means of at least one elastic blade 19 on which is fixed a piezoelectric ceramic 24. At the level of its junction with the element 9, one of the two faces 20 of the blade 19 is extended with respect to the other face, by virtue of an extension formed on said element 9. The ceramic 24 is then fixed on the blade 19, so as to bear on said extension. / p & & p & the invention makes it possible to increase the efficiency of the ceramics used for the activation of the laser gyrometer and to reduce their number.
