摘要： A linear ultrasonic motor includes a vibrator having a piezoelectric element, a movable part applying a pressing force to the vibrator and bringing the vibrator into pressed contact with a base part, a cover part being fixed to the base part, a rolling part being rollably held between a movable guide part of the movable part and a cover guide part of the cover part, and a body to be driven having a transmission member that is pivotably supported and able to move only in the movable direction. The transmission member includes a bias part that abuts on a transmission part of the movable part and applies a biasing force of biasing the movable part to the rolling part to the transmission part. The rolling part is held by a resultant force of the pressing force or a reaction force of the pressing force, and the biasing force.

摘要： To improve both of the mechanical reliability and electrical reliability of an electronic apparatus including a piezoelectric body, a vibrator, and a vibration wave motor. The piezoelectric body is configured by bonding a piezoelectric element and a flexible printed circuit substrate FPC, a coverlay has an end N made up of a first outline part and a second outline part that intersect with wiring layers, the first outline part coming in contact with an electrode F1 of electrodes F, and the second outline part coming in contact with another electrode of the electrodes F. Length L1 from an outer-shape line M of the piezoelectric element that intersects with the FPC to the first outline part is shorter than length L2 from the outer-shape line M to the second outline part, and the electrode F1 is located closer to the outer-shape line than the other electrode of the electrodes F.

摘要： Similar to combustion engines including multiple cylinders engaged with a crankshaft, multiple piezoelectric stack actuators (PSA) engaged with a common output rod can produce smooth, long stroke motion with desired properties. In particular, when equally spaced multiple units are arranged to push sinusoidal gear teeth on the output rod, the system exhibits unique collective behaviors thanks to “harmonic” effects of the multiple units. For example, although the force-displacement characteristics of individual units are highly nonlinear, the undesirable nonlinearity, including singularity, may be eliminated. Here it presents harmonic analysis, design, and control of a class of actuators consisting of multiple driving units engaged with a sinusoidal transmission, termed a harmonic poly-actuator. Through theoretical analysis, it is obtained 1) conditions on the unit arrangement to eliminate their nonlinearity from the output force, 2) control algorithms for coordinating the multiple units to generate a commanded force with desired force-displacement characteristics, and 3) a method for compensating for output force ripples due to possible misalignment and heterogeneity of individual units. The control algorithms are implemented on a prototype harmonic poly-actuator with six units of PSAs. Experiments demonstrate the unique features of the poly-actuator exploiting inherent redundancy and harmonic properties of the system.

摘要： THIS invention relates to a piezoelectric actuation device and more particularly but not exclusively, to a piezoelectric actuation device with three piezoelectric actuator sets. The device includes a first clamp arrangement being displaceable between an engaged position and a disengaged position and a second clamp arrangement being displaceable between an engaged position and a disengaged position. The device also includes an actuation arrangement being displaceable between a first condition and an inverse second condition; and force transmission means for transmitting a force to a load applied thereto, with the force transmission means being coupled to the actuation arrangement. The device is characterized in that the actuation arrangement displaces the force transmission means when it is displaced from the first condition to the second condition, and also displaces the same force transmission means when it is displaced from the second condition to the first condition within a single actuating cycle.
