摘要： The invention relates to a manipulator comprising an end effector (27) displaceable by means of a rod mechanism comprising four arms (11,13,15,17). By means of simultaneously activated individual drives (29,35) for two of the arms (11,15) which are of equal length, which individual drives are integrated in a differential drive, a displacement of the rod mechanism is obtained in a plane at right angles to a main axis (3) about which the two arms (11,15) are rotatable. At the same and oppositely directed angular velocities of the arms (11,15) about the main axis (3), a radial (R) positioning of the end effector (27) takes place, while at the same angular velocities of the arms (11,15) in the same direction an angular (.theta.) displacement of the end effector (27) about the main axis is obtained. The manipulator is particularly suitable for use as assembling robot.

摘要： A driving mechanism having a spindle which is provided with a first helical threaded portion having a lefthand direction of rotation and with a second helical threaded portion having a righthand direction of rotation. A pair of spindle guides each engage a respective spindle threaded portion for rotating the spindle and translating the spindle in an axial direction. Each spindle guide has three pairs of runner rollers on a sleeve for centering and supporting the spindle within the sleeves. The three pairs of runner rollers on each sleeve kinematically constrain the six degrees of freedom of the spindle without overconstraint to reduce friction and binding of the spindle in the spindle guides.

摘要： A shaving apparatus is provided which comprises a housing having a shaving head carrying an external shaving member with hair-entry apertures and an internal shaving member which is coupled to a motor in the housing and which is drivable relative to the external shaving member with a combined movement, the combined movement comprising an oscillatory rotation about an axis of rotation of the internal shaving member and a reciprocating movement in the direction of the axis of rotation. The internal shaving member is provided with a support which is flexible in the direction of the axis of rotation but which is stiff in directions transverse to said direction of the axis of rotation, and the support rotatably supports an internal shaving-member holder which is coupled to the motor. The external shaving member is secured to a frame and is movable relative to the shaving head against spring force in a direction transverse to the axis of rotation, the frame and the shaving head being provided with corresponding guide means.

摘要： An electromechanical displacement device (81) provided with a holder (90), an element (45) displaceable relative to the holder (90), and an actuator (83) connected to the holder (90) by which the element (45) can be displaced relative to the holder (90). The actuator (83) is provided with at least a first and a second clamping member (B, A) which can be clamped alternately against the element (45) under a mechanical pretensioning force F.sub.k, at least one clamping member (A) being provided with at least one piezoelectric, electrostrictive or magnetostrictive clamping element (61). The actuator (83) is further provided with a piezoelectric, electrostrictive or magnetostrictive transport element (69', 69") by which the distance between the clamping members (A, B) can be changed. When the first clamping member (B) is clamped against the element (45) under the mechanical pretensioning force F.sub.k while the second clamping member (A) is disengaged therefrom, activation of the clamping element (61) transfers the mechanical pretensioning force F.sub.k to the second clamping member (A), so that the second clamping member (A) is clamped against the element (45) under the mechanical pretensioning force F.sub.k, while the first clamping member (B) is disengaged therefrom.

摘要： A magnetic-tape apparatus has a magnetic-head unit with a magnetic head having a head face for guiding a magnetic tape. The magnetic head has transducing gaps for writing and/or reading information onto/from the magnetic tape. The magnetic-head unit further comprises two height limiters having tape-guide surfaces for guiding an edge of the magnetic tape. A tangent line, which is tangent to both tape-guide surfaces, extends perpendicularly to an imaginary line in the head face and passing through the transducing gaps. If an edge of the magnetic tape is in contact with the two height limiters, the position of the magnetic tape relative to the magnetic head is always the same, so that no azimuth errors can arise. In order to bring this edge of the magnetic tape into contact with the height limiters, the magnetic-head unit is mounted so as to be pivotable about an axis perpendicular to a tangent plane to the head face at the location of the transducing gaps. This axis extends through the center of gravity of the magnetic-head unit.
摘要翻译： 磁带装置具有磁头单元，磁头单元具有用于引导磁带的磁头面的磁头。 磁头具有用于向/从磁带写入和/或读取信息的换能间隙。 磁头单元还包括两个高度限制器，其具有用于引导磁带边缘的带引导表面。 与两个带引导表面相切的切线垂直于头部表面中的假想线延伸并且穿过换能间隙。 如果磁带的边缘与两个高度限制器接触，则磁带相对于磁头的位置总是相同的，从而不会产生方位误差。 为了使磁带的这个边缘与高度限制器接触，磁头单元安装成在换能间隙的位置处绕垂直于切平面的轴线枢转到头部面。 该轴线延伸穿过磁头单元的重心。

摘要： A transmission with variable mechanical prestress including a pinion driven by an electric motor, a driven gearwheel with its bearings in a housing, and an electromagnetic actuator for applying a prestress force which is controllable in dependence on an instantaneous load to be handled by the transmission. The electric motor with the pinion is supported so that it can be tilted relative to the housing. Owing to a tilting movement of the electric motor caused by the actuator, the pinion is pressed against the gearwheel with a certain prestress force in a radial direction. The transmission is free from play, while the virtual play arising from friction and hysteresis is strongly reduced, and the positioning accuracy is enhanced as a result.

摘要： A transmission system comprising at least two wheels and a belt wound around the wheels with an unambiguous transmission ratio in that the transmission system is free from clearance and is comparatively stiff, while geometric errors, such as the polygon effect, and manufacturing errors and the occurrence of slip are neutralized in that the wheels are subdivided into segments, which can separately perform a tangential displacement. The belt has spaced opening for receiving the segments, which tangentially displace in case of misalignment of the segments to the belt openings. The belt has spaced opening for receiving the segments, which tangentially displace in case of misalignment of the segments to the belt openings.
