Abstract: PROBLEM TO BE SOLVED: To reduce the amount of the movement, which is out of the plane along the housing z-axis of a transducer, during an assembling and to accurately and speedingly conduct a device positioning by generating the movement of the housing along an x-axis or a y-axis caused by the expansion or the contraction of the transducer. SOLUTION: At the time of assembling an electrical/mechanical transducer 22 into a housing 12, the transducer 22 is mounted onto a deflection joint insert 30 to produce a single subassembly and the subassembly is inserted into an opening section 14. Then, an electric field is applied to the transducer 22 to measure the amount of the movement of the housing 12. Then, the insert 30 is moved in the section 14. Then, an electric field is applied to the transducer 22 to measure the amount of the movement of the housing 12. The above processes are repeated for several moved positions of the insert 30, the data are analyzed and the position of the insert 30, where the amount of the movement in the z-axis direction becomes a minimum, is determined.

Abstract: The positioning arrangement (10) includes a casing (12) which comprises a first interior aperture (14), and a first electro-mechanic, especially piezo-electric, transducer (22) which is arranged within the first aperture. At least two bending joint inserts (30) connect the first transducer with the casing. The transducer has a longitudinal axis (CL), and the joint inserts comprise respectively a pivot point (31) which is displaced with respect to the longitudinal axis. The casing is preferably formed of aluminum, and the joint inserts of steel.
