摘要： According to one embodiment, generating images according to intersection points includes obtaining samples of signals from transmitter-receiver pairs. A transmitter-receiver pair is configured to transmit a signal and receive the signal reflected by an object. Intersection points are determined, where an intersection point indicates an intersection for integer multiples of a sample-time distance. A subset of samples corresponding to the intersection points is selected. Image data is generated from the selected subset of samples, where the image data is used to generate an image of the object.

摘要： A stage device is equipped with a first scale which is placed with a Y-axis direction serving as its longitudinal direction and in which a first grating whose periodic direction is in an X-axis direction is formed and a second scale which is placed with the X-axis direction serving as its longitudinal direction and in which a second grating whose periodic direction is orthogonal to the periodic direction of the first grating is formed, the first scale and the second scale being placed on a plane which a wafer stage faces. Further, on the upper surface of the wafer stage, a plurality of X heads placed at different positions in the X-axis direction and a plurality of Y heads placed at different positions in the Y-axis direction are arranged. An encoder system that has these heads measures positional information of the stage within an XY plane, based on an output of the X head facing the first scale and an output of the Y head facing the second scale.

摘要： Two transducers to be rotated around a circumferential location on a cylindrical body for structural testing of the body are carried on a mounting and drive apparatus including a magnetic attachment which can be manually brought up to a pipe from one side only for fixed connection to the pipe on that side at a position axially spaced from a weld. A collar shaped support for the pair of transducers is formed of a row of separate segments which wrap around the pipe from the one side and is rotated around the axis of the pipe to carry the transducer around the circumferential weld. The segments carry rollers to roll on the surface and are held against the pipe by magnets. The transducers are carried on the support in fixed angular position to track their position but in a manner which allows slight axial or radial movement relative to the pipe.
