摘要： A polygonal mirror is provided which presents a plurality of mirror surfaces arranged about an axis of rotation with all the mirror surfaces at the same inclination relative to that axis. The mirror comprises a reflecting foil tightened over a plurality of supporting elements arranged about the axis of rotation. Equal angles between the mirror surfaces are obtained by employing cylinders as the supporting elements. The cylinders all have the same outside diameter, and are placed together with each touching two neighboring cylinders and each in contact with a central cylinder the axis of which coincides with the axis of rotation.

摘要： A piezoelectric drive having an excitation piezoelement (10) and a resonator (2). The resonator is coupled to the piezoelement and is in interactive connection with a body (3) to be driven. The resonator (2) has a mass distribution that is designed such that, as a result of an excitation oscillation by the piezoelement (10), the resonator (2) begins to asymmetrically oscillate in several directions dependent on the frequency of the excitation oscillation. The asymmetric oscillations, via the interactive connection, displace the body to be driven into a directed movement.

摘要： An inkjet array for a printer includes a number of elements. Each element has an ink chamber and an ink provider, and a piezo-actuator rigidly secured to one side of the ink chamber. The ink chamber is brought into motion in response to an image signal whereby an ink droplet is ejected from a nozzle of the ink chamber. Each of the ink chambers of the array can be brought into motion separately.
