Abstract: A piezoelectric actuator having an active module formed by laminating a plurality of piezoelectric elements, in which the cross-sectional area of the element proximate the fixed end of the module is larger than that of the element proximate the movable end thereof.

Due to the above structure, a decrease in the inertial load can be realized, thereby preventing the elements near the fixed end from being damaged.

Abstract: Mechanical resonance of the vibratory feeder is maintained by minimizing a phase angle difference between substantially sinusoidal drive voltage and current wave forms. The mass flow rate of material being fed is controlled by controlling the electrical power applied to the vibratory feeder compared with a desired electrical power computed from a desired flow rate. The preferred embodiment includes synthesized drive wave forms which are variable in frequency and amplitude in order to maintain the vibratory feeder in mechanical resonance at the desired flow rate. Resonant operation and accurate material flow are accomplished without use of electromechanical vibration sensors and control is accomplished using the magnitude and phase relationships between the applied voltage and current drive wave forms.
