Abstract: A microstepper motor which comprises two electromechanical drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. The actuators are non-radially hinged to the drive ring via an approximately square shear-flexible and torsion-proof frame structure, the drive ring being arranged inside said frame. The drive according to the invention is compact, the frame and the drive ring being configured as a single injection-molded drive module.

Abstract: A motor which includes two drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. Diagonally opposite securing elements are provided on the drive ring and are used to flexibly suspend the drive ring via respective articulated corner elements on respective fixing elements that are diagonally opposite the respective securing elements. The drive according to the invention is compact, having actuators that are non-radially hinged to the drive ring.

Abstract: A microstepper motor which comprises two electromechanical drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. The actuators are non-radially hinged to the drive ring via a torsion-proof, nested frame-type complex structure (drive module) including an interior drive ring, a frame and a U-shaped outer frame. The drive is compact and, the drive module is configured as a single injection-molded structure.

Abstract: An information converter has at least two material layers having polygonal base surfaces, which are connected to each other in a shear-rigid way, wherein at least in one material layer a change of length can be induced. The polygonal base surface has at least two different interior angles.

Abstract: A motor which includes two drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. Two tension-compression bars, which are parallel to an effective direction, are connected to the drive ring, have respective joints at their ends and are connected to the ends of a diagonal bar, relative to which the ring can be displaced in the other effective direction. The diagonal bar itself can be displaced relative to fixing elements to an effective direction via a diagonal suspension. The drive is compact, having actuators that are non-radially hinged to the ring.

Abstract: A display instrument with two illuminated pointers, in which instrument the illuminated pointers (4, 6) are supplied with light via a light splitter (10). The latter has a frustum-shaped depression (21) so that a portion of the light is radiated in the axial direction and passes into the upper illuminated pointer (4). A further portion is scattered radially at the generated surface (24) of the frustum (23) and passes into the lower illuminated pointer (6).

Abstract: A method is provided for manufacture of an electronically synchronizable indicating instrument the pointer of which can be turned between a zero stop and a scale-end by means of a stepping motor via a multi-step gearing, wherein the stepping motor has a two-pole rotor of magnetizable material, two coils arranged perpendicular to each other, and a housing surrounding the coils, the motor being adapted to be controlled by a microprocessor. The stepping motor is assembled with a non-magnetized rotor, and the instrument includes a gear train, and a pointer having a torsion spring which acts in the direction towards full scale. In the procedure of the method, the pointer is brought to rest against the zero stop by means of a moment of rotation applied from the outside in opposition to the restoring force of the torsion spring.
