摘要： A machining tool holder (100, 200) including a body (10), a horn (20, 50) and a piezoelectric actuator (32) is disclosed. The body (10) includes a center through hole (12) extending in the axial direction therein. The center through hole (12) includes a first hole section (121) and a second hole section (123). The horn (20, 50) includes a first section (22, 52) and a second section (24, 54) which are disposed coaxially and connected with each other. Part of the first section (22, 52) is slidably inserted into the first hole section (121). The second section (24, 54) is connected to the body (10) and engaged with a tool (3). Part of the surface of the second section (24, 54) contacts with a wall surface of the second hole section (123). The piezoelectric actuator (32) fits around the horn (20, 50) and is controllable to drive the tool (3) to vibrate. With this design, the machining toolholder (100, 200) could have good stiffness and connection stability, and could resist to the stress effectively.

摘要： A stator consists of two metal blocks (13,14), two piezoelectric vibrators (16,17) and two electrodes (18,19) and the length of one metal block is very much longer than that of the other metal block (14). When alternating current voltage is applied to the piezoelectric vibrators of the stator, a linear progressive wave is generated on the end of the stator by compounding longitudinal vibration generated by the piezoelectric vibrators with bending vibration generated in the stator. A member is linearly or rotatively driven by one or more stators.

摘要： A vibration actuator has an elastic member formed into a ring shape, an electro-mechanical converting element joined to the elastic member, and a relative moving member which is in press contact with the elastic member. In the vibration actuator, the electro-mechanical converting element generates, upon application of a driving signal, a first vibration mode that vibrates in a direction parallel to a reference plane where the ring shape is formed, and a second vibration mode that vibrates in a direction perpendicular to or substantially perpendicular to the reference plane, and the relative moving member moves relative to the elastic member in one- or two-dimensional directions in the reference plane by the first and second vibration modes.

摘要： A multi-DOF piezoelectric actuator that may be constructed with sizes of about or less than one millimetre. The multi-DOF piezoelectric actuator is capable of generating motion of a rotor element or slider element, about or in, each of the three fundamental axes of three dimensional space. The actuator can comprise a piezoelectric element (10) having one or more sidefaces, a first endface, and a second endface, wherein at least one or more sidefaces comprise a plurality of separate sideface electrodes (11) and at least one of the first or second endfaces comprise an endface electrode (12). A transducer element (30,40) and isolation structure (5) for use in a piezoelectric actuator are also described.
