  • Patent number: 6354168
    Abstract: A tripod bearing device featuring a stationary frame and a carrier moveable relative to it, which are connected together via three braces that are adjustable in their lengths. Each brace is coupled to the frame and to the carrier via a joint each with two rotational degrees of freedom. Moreover, a torsion drive is assigned to each brace for twisting the carrier-end joint of the relevant brace relative to the frame-end joint of this brace about its longitudinal axis. Consequently, a constructively simple parallel structure with three machining axes can be realized which, with its high dynamic stiffness, enables an accurate positioning of the carrier. Furthermore, a method for torsion compensation in the braces is given.

  • Patent number: 6354167
    Abstract: A SCARA type robot with counterbalanced arms and tilting base. This apparatus enables accurate planar movement of a probe. Weak or flexible foundations or footings do not affect positioning accuracy of the probe. Positioning accuracy, relative to the movement plane, of a probe is unaffected by positions of the arms. At any angle of the probe movement plane the counterbalanced arms allow the same size drive motors, torque transmission devices, and drive electronics. These features make the invention very useful for on-site or portable near-field testing of antennas. A manipulator may be used in place of the probe. Most of the benefits will be retained if load variations on the manipulator are kept small.

  • Patent number: 6349606
    Abstract: Apparatus embodying the invention includes first and second motors coupled to a carriage assembly for moving the carriage assembly back and forth between first and second end points. The first motor is for developing a force to drive the carriage in one direction and the second motor is for developing a force to drive the carriage in an opposite, second direction. When the first motor causes the movement of the carriage in one direction, the slowing, stopping and reversal of the carriage is achieved by varying the power supplied to the second motor relative to the power supplied to the first motor until the force exerted by the second motor first equals and then exceeds the force exerted by the second motor. So operated, the carriage motion is well controlled and exhibits little, if any, backlash.

  • Patent number: 6339970
    Abstract: In a steering column (1) which is telescopic in the event of a crash, an outer column tube (6) is connected to a stem (7) by means of a shearing body (10). This two-piece shearing body (10) has a shearing area which is reduced relative to its external dimensions and is determined by a projection connecting its two sections (11, 12). The shearing body (10) can therefore absorb relatively large axial forces, for example for assembly purposes, and yet permits maximum admissible shearing forces which can be set largely as desired and which at the same time can be reproduced with high accuracy.

  • Patent number: 6336373
    Abstract: A drivig rotary shaft and a follower rotary shaft are rotatably carried in a housing of a rotary solenoid. Operating members fixed to the rotary shafts by clips are operatively connected to each other by gears, and a locked member is locked non-movably by locking surfaces formed at tip ends of the operating members. This makes it unnecessary to provide a device for converting a rectilinear motion to a rotational motion such as a pin and an elongated bore in a path of transmission of a driving force from the rotary solenoid to the operating members. Therefore, not only the number of parts and the number of assembling steps are reduced, but also the number of slide areas, where a friction resistance and looseness are liable to be produced, is reduced, thereby enabling a noiseless smooth operation.
