摘要： In a vibration wave driven motor, when the radius of the arcuate portions and the length of the straight portions of a track type resilient member of an elliptical shape having straight portions and arcuate portions are (R) and (L), respectively, the ratio (R/L) is made equal to or greater than a particular value, whereby the resonance frequencies of two standing waves can be made coincident with each other and the torsion component of the straight portions can be reduced or the direction of the torsion can be made uniform with a result that the driving characteristic in the straight portions can be improved and also the electrode pattern of a piezo-electric element can be simplified.

摘要： In a vibration wave driven motor having a vibration member having an electro-mechanical energy conversion element secured to one surface of a resilient member of an elliptical shape formed by straight portions and arcuate portions, and a member brought into pressure contact with the other surface of the resilient member and wherein AC voltages having a phase difference of 90.degree. therebetween in terms of time are applied to the driving phases of the electro-mechanical energy conversion element divided into two phases to thereby generate a travelling vibration wave in the resilient member, whereby the vibration member and the member brought into pressure contact therewith are moved relative to each other, the two driving phases of the electro-mechanical energy conversion element are polarization-processed in such a manner that only one travelling wave is formed in the straight portions of the resilient member.

摘要： In a vibration wave driven motor, an elastic body of an elliptic shape is provided where different degrees of stiffness or rigidity are available with the arcuate portions and the straight portions, and the ratio between the distortion energy and the vibration energy that part in the generation of the natural frequency for the A vibration mode is arranged virtually equal to that ratio for the B vibration mode, thus enabling the matching of frequencies for both A and B modes.

摘要： An actuator manufacturing method includes alternately stacking a plurality of dielectric elastomer layers and a plurality of conductive rubber layers along the direction of thickness to form a sheet, and wrapping the sheet formed about a core to form a rolled sheet. When the sheet formed in the step of alternately stacking is wrapped about the core, the sheet is formed by the dielectric elastomer layers and the conductive rubber layers. Therefore, even if the dielectric elastomer layers in the sheet are made to be thin, the thickness of the entire sheet is prevented from being excessively thin.
