Abstract: An endoscopic ultrasound probe for use in transesophagael echo cardiography comprises a rotatable ultrasound transducer array (12) for obtaining two-dimensional cross-sectional images along a variety of scan planes. The array is formed of a plurality of transducer elements (12A - 12K) and rotates about an axis perpendicular to the plane of the transducer elements. The rotating array (12) defines a circular region of rotation and has a surface area which substantially matches the area of the circular region of rotation within the probe. More specifically, the elements of the array have varying mechanical lengths such that the rotatable array may have a substantially circular shape.

Abstract: An improved linear bearing assembly comprising sets of guides (ways) for guiding rolling elements (ball bearings or rollers) constrained within a cage (12). Typically, two sets of rolling elements (14) and cages (12) are used between a moving part and a stationary part. Each set has four resilient elements (springs) (16) with one end of each spring (16) anchored to the cage (12) and with the other ends of two springs (16) anchored to the stationary way or part and the other ends of the other two springs are anchored to the movable way or part. This arrangement provides a restoring spring force that gradually forces the cage to its correct tracking position. If the (12) cage is tracking properly, the spring forces cancel out and there is no inherent rubbing in the restoring mechanism.

Abstract: A fixedly held tube (1) is to be cut by revolving radially arranged cutting tools (15). The cutting tools are located on a rotating tool carrier (12) with a main drive (18). Each tool is mounted on a radially displaceable slide (14) with a spindle (22). A hollow shaft (20) of the feed element is arranged coaxially to the tool carrier and is connected to the output (24) of a differential mechanism via gearwheels. The differential mechanism can be controlled via a servomotor (27) by means of a differential member (26) in such a way that the tool carrier and the hollow shaft rotate synchronously, with the result that no feed takes place, or that, due to speed differences, a feed or reverse motion of the tool slide is effected. Since a low force is required for the servo control, the feed is particularly precise. <IMAGE>
