摘要： A rotating machine comprises a stator that is excited to vibrate to generate progressive surface waves at a frequency within a resonance frequency range of a predetermined rank. The rotor is designed so that the vibrations in the stator generate vibrations of the same frequency and of lower magnitude. A vibration sensor is mounted on the rotor to provide a signal. The difference in frequency between the excitation frequency of the stator and the vibration frequency detected on the rotor corresponds to the rotation speed of the rotor.

摘要： The invention relates to the detection of liquid in a cavity of a structure, e.g. a sandwich-structure cell with honeycomb core and carbon fiber composite coating. The structure is subjected to a mechanical vibration, at a frequency fm in the audible range, by an excitation wave, the area being explored is subjected to an incident electromagnetic wave and the reflected electromagnetic wave is analyzed to deduce therefrom the presence or the absence of liquid in cavities. The Faraday wave induced on the surface of the liquid in the cavity comprises subharmonic frequencies of fm which modulate the reflected electromagnetic wave and make it possible to identify the presence of liquid. A detection apparatus comprises an excitation wave generation device for generating the vibration excitation wave, an electromagnetic wave generation device for generating the incident electromagnetic wave, a measuring device for detecting and measuring the reflected electromagnetic wave, and a signal processor.

摘要： A rotary piezoelectric motor (1) in which a geometrical asymmetry can be introduced, e.g. in the counter-masses (11, 14) or in the stator fixing elements (10), in order to produce a phase shift previously obtained using a phase quadrature power supply. A simplified single-phase power supply (40) can be used with one such motor. The inventive motors offer advantages in terms of cost and reliability, particularly for motors that require only a single direction of rotation. The motors are particularly suitable for small motors such as those used for clock and watch making, microsurgery or microelectronics.
