摘要： A fluid jet dispenser using at least two multilayer piezoelectric actuators is provided. The fluid jet dispenser includes a dispensing head and an electrical driver. The dispensing head includes at least two d31-mode multilayer piezoelectric actuators, a displacement magnifying element mechanically coupled to the d31-mode multilayer piezoelectric actuators, a piston, and a nozzle. More preferably, the two d31-mode multilayer piezoelectric actuators operate in an anti-phase condition. The electrical driver is electrically coupled to the d31-mode multilayer piezoelectric actuators for displacing the actuators in directions substantially perpendicular to polarization of piezoelectric layers in the d31-mode multilayer piezoelectric actuators in response to charging and discharging of the actuators by the electrical driver, to generate a fast movement of the piston to jet a pressurized fluid out of the nozzle of the dispensing head.

摘要： A piezoelectric actuator with integrated features to provide coarse position adjustment of a pushing threaded rod and also mechanically amplified piezo motion for fine position adjustment is presented here in three design variants. The mechanical amplifier houses one or more piezo stacks in longitudinal axis with preload to translate an amplified motion in the order of a few times in the transverse axis, perpendicular to the piezo stack motion. The piezo amplifier output travel is transmitted to the threaded rod with a ball at the end to push a desired surface for position adjustments and motion translation in application such as a mirror mount.

摘要： A system that includes an actuator amplification apparatus and a push pull actuator disposed on or within the actuator amplification apparatus. The actuator amplification apparatus is configured to receive a push pull actuator. The actuator amplification apparatus includes a body fixture configured to attach the actuator amplification apparatus to a fixed mass, an output interface to attach the actuator amplification apparatus to a moving mass, and an integral amplification mechanism. The integral amplification mechanism of the actuator amplification apparatus amplifies a force output by the push pull actuator to the moving mass. The integral amplification mechanism includes a plurality of linkages or an integral lever arm. The actuator amplification apparatus may include stabilizers configured to limit movement of the push pull actuator. In an embodiment, the fixed mass is a dashboard frame of an automobile and the moving mass is a floating haptic touch screen assembly.

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.
