    摘要： An optical scanning device includes an optical deflector, a driving unit, and a detection unit. The optical deflector has a mirror part and an H actuator. The driving unit supplies both of a first driving voltage and a second driving voltage to a first set of piezoelectric divided sections and a second set of piezoelectric divided sections of the H actuator during a first driving period, and supplies the driving voltage only to one set out of the first set and the second set of piezoelectric divided sections during a second driving period. The detection unit detects a deflection angle γ based on the output voltage of the other set of piezoelectric divided sections during the second driving period.

    摘要： An wobble motor with an actuator extending in a Z direction between opposite mount and tool ends and comprising two sections offset in that Z direction. Each section comprises a structure of electrodes interleaved in a piezoelectric material in such a way that a Y-region can cause deflection in a Y-direction perpendicular to the Z-direction upon energizing of associated electrodes and such that a X-region can cause deflection in an X-direction perpendicular to the Y and Z directions upon energizing of associated electrodes.

    摘要： Provided is an injector in which adhesion between a stator and a rotor of an ultrasonic motor can be released efficiently. An injector (1) which injects a chemical liquid includes: an ultrasonic motor unit (3) including an ultrasonic motor (31); a drive mechanism (4) to be driven by the ultrasonic motor unit (3) so as to feed the chemical liquid when the ultrasonic motor (31) rotates forwardly; and a control device (5) which controls the ultrasonic motor (31) of the ultrasonic motor unit (3). The ultrasonic motor (31) includes a stator (32) and a rotor (33), and the control device (5) controls the ultrasonic motor (31) to alternately repeat forward rotation and reverse rotation so that adhesion between the stator (32) and the rotor (33) is released.
