20130230196 | OSCILLATORY WAVE MOTOR AND SOUND GENERATION DEVICE USING OSCILLATORY WAVE MOTOR AS DRIVE SOURCE - The present invention addresses the problem of increasing the lifetimes of an oscillatory wave motor and a sound generation device using the oscillatory wave motor as a drive source, and proposed the structure and mechanism for integrally increasing the lifetimes of the oscillatory wave motor and the sound generation device using the oscillatory wave motor as the drive source. To maintain the drive performance of a drive unit, the drive unit is provided with a core sheathing structure, with the result that the drive unit is prevented from breaking and being damaged, and even if the entire drive unit is worn down, an intrinsic drive unit member serving as a core portion keeps the same drive area, so an initial drive feature is maintained. The descending order of a wear resistance of the members is the drive unit core material, a moving unit, and a drive unit sheathing material. In the oscillatory wave motor including a second drive mechanism, when performing an original operation of the oscillatory wave motor, a driven area on the moving unit is relatively drifted at the same time. | 09-05-2013 |

20100072858 | VIBRATOR FOR ULTRASONIC MOTOR - In the invention, each piezoelectric element for a vibrator for an ultrasonic motor has electrode regions for exciting stretching vibration and flexural vibration separately. Thus, the invention provides a vibrator for an ultrasonic motor, in which electrodes are provided for applying voltage to each of the polarized region, and further provides a stack-type piezoelectric vibrator for an ultrasonic motor, consisting of a stack of the said vibrators and having an extraction electrode pattern provided for short circuit with an external electrode. The vibrator of the invention has high controllability, especially in a fine movement region and is useful as a driving source in a positioning device, in which enhanced vibration efficiency can be obtained. | 03-25-2010 |
