    摘要： The present invention provides a piezoelectric actuator mechanism that is suited for automatic operation in the adjustment of a mirror holder in an optical system, or in the positioning of a movable table of a linear stage, that has a short entire length, and is capable of performing a compact and high-precision position/angle adjustment and positioning. The piezoelectric actuator mechanism comprises: a screw-driven feeding mechanism that is comprised of a feed screw 11 and a feed screw nut 14; a disc-shaped rotor 17 mounted on the rear-end face of the feed screw nut 14; an ultrasonic motor 18 having a piezoelectric vibrator 19 that comes in contact with the circumference face of the rotor 17; and a driven mounting portion that is pressed against the leading end of the feed screw 11 by spring force, and displaced and positioned by the feeding operation of the feed screw. The driven mounting portion can be made to be a mirror holder 1 to be used in an optical system, or a movable table 21 of a linear stage, for example.

    摘要： Electrodes (7, 8, 9), having curved sections in the shape of the outline thereof, are disposed in areas of a rectangular plate-shaped piezoelectric transducer element (1) in which the strain in the natural mode of vibration is large. The eletrodes (7, 8) which excite a bending vibration are disposed in areas in which the strain in the bending natural mode is at least a predetermined value, and the outline curved sections of the electrodes (7, 8) are shaped so as to follow along strain contours (3, 4), and the electrode (9) which excites a stretching vibration is disposed in an area in which the strain in the stretching natural mode is at least a predetermined value, thus providing a transducer for an ultrasonic motor which aims to reduce transducer loss (increasing vibration efficiency), and improve transducer durability and reliability.

    摘要： A method for cutting a workpiece into cut piece or cuttings having a predetermined equal weight, which is disclosed herein, comprises the steps of performing a trial cutting of a workpiece along a predetermined trial cutting plane to provide a trial cut piece or cutting, measuring a weight of the trial cut piece, determining a weight per unit length of the trial cut piece on the basis of the weight and the position of the trial cutting plane of the trial cut piece, determinig the position of a first cutting plane for a first cut piece of a predetermined weight adjacent the trial cut piece by calculation based on the weight per unit length of the trial cut piece, performing a first cutting of the workpiece along the first cutting plane to actually provide the first cut piece adjacent the trial cut piece, and likewise determinig the position of an n-th cutting plane for an n-th cut piece by calculation based on the weight per unit length determinedon the basis of the weight and the position of the cutting plane of a jast last cut piece, i.e., an n-th cut piece, and performing an n-th cutting of the workpiece along the n-th cutting plane to actually provide the n-th cut piece. With this method, it is possible to cut a workpiece with an extremely good accuracy into cut piece or cutting each having a desired weight and high commercial value, and thus to effectively utilize the workpiece without any waste, leading to a reduced cost.
