Abstract: A piezoelectric sheet conveying device of a linear contact type contains a pair of rollers containing the sheet therebetween. The first roller is driven by a piezoelectric vibrator forming a contact line between the edge insert of the vibrator and the outer surface of the first roller. The vibrator is urged against the first roller by a bias spring. The hardness of the edge insert of the vibrator is about 5x107 N/cm2 and much higher than the hardness of the first roller being about 2x106 N/cm2. As a result, elastic compressions of the first roller are achieved during periodic elongations of the vibrator and engagements of the first roller surface. Microgroove is formed along the contact line between the vibrator and the first roller which transmits the rotational torque to the first roller and advances the sheet in a predetermined direction. Subsequent contraction of the vibrator restores the outer surface of the first roller to its initial shape. Both the first roller and the vibrator can be made as laminated structures to achieve respectively correct composite hardness and reduce the driving voltage.

Abstract: A reversible positioning device contains a piezoelectric actuator (10) of a linear contact type urged against a rotary or a linear type movable element (20). The actuator is equipped with two sets of electrodes: (90), (110), (80) and (100), (120), (80) respectively. The control unit supplies electrical impulses to either one of the theses sets of electrodes to initiate periodic oscillations of the actuator (10) causing elastic compressions of the movable element (20) and subsequent movements in either one of the opposite directions. One particularly useful application is in the movable arm of the disk drive data storage system such as a CD-ROM or alike. Extreme accuracy of positioning of a readout head and a low inertia allow for fast response time approaching 2 msec. a novel control method is in supplying a higher voltage from a control unit for the longer forward motion of the positioning device followed by a shorter back movement due to lower voltage. That control method increases the positioning accuracy even further to as low as 0.2 microns.

Abstract: A piezoelectric motor (100) of a linear contact type contains one or more actuators (150 and 151) placed about a rotor (140). Each actuator (150) contains at least one piezoelectric vibrator (120) with a working end (133) urged against the rotor (140). Periodic oscillations of each vibrator (120 and 121) cause compressions of the rotor (140) not exceeding its natural elastic compression limit so after its compression the rotor (140) fully restores its initial cylindrical shape. Such elastic compressions ensure longer operational life of the motor. In another embodiment, each actuator (200) has a laminated design with at least two vibrators (221 and 222) separated by an isolator (223). The isolator extends beyond the vibrators and has appropriate hardness to engage with the rotor (240). A rotor of laminated design is also described to achieve the optimum hardness relative to the hardness of the actuators. The hardness of the vibrator edge is about 5x10 N/cm and is much higher than the hardness of the rotor being about 2x10 N/cm . A disk drive is described as one of the most advantageous applications of the motor of the invention to drive optical and magnetic disks such as in a CD-ROM drive etc.
