An inspection device inspects a joint-type outer joint member of a constant velocity universal joint that includes a cup section having a bottomed cylindrical shape and track grooves in an inner periphery thereof for torque transmitting elements, and a shaft section extending from a bottom of the cup section. The inspection device inspects the outer joint member, which is obtained through melt-welding on a cup member forming the cup section and a shaft member forming the shaft section. The inspection device includes a surface inspection unit to inspect for a defect which appears on a surface of the outer joint member due to welding, an internal inspection unit to inspect for an internal defect of a welded portion, and a recording unit to record an inspection result of the inspection. The inspection device is configured to efficiently perform in-line total inspection for the melt-welded joint-type outer joint member.

An automated device for non-destructive testing for the detection of defects of a complex tubular product includes at least one ultrasound transducer arranged to emit an ultrasound beam having an emission orientation. The automated device further includes control and processing electronics configured to define at least one ultrasound burst parameter as a function of the longitudinal and/or circumferential position of the ultrasound emission means, so as to detect defects in the tube wall. The at least one parameter being chosen from the burst emission orientation, the gain or the position of the temporal filter.

A method to perform sub-surface detection of nanostructures in a sample, uses an atomic force microscopy system that comprising a scan head having a probe with a cantilever and a probe tip arranged on the cantilever. The method comprises: moving the probe tip and the sample relative to each other in one or more directions parallel to the surface for scanning of the surface with the probe tip; and monitoring motion of the probe tip relative to the scan head with a tip position detector during said scanning for obtaining an output signal. During said scanning acoustic vibrations are induced in the probe tip by applying a least a first and a second acoustic input signal respectively comprising a first and a second signal component at mutually different frequencies above IGHz, differing by less than IGHz to the probe, and analyzing the output signal for mapping at least subsurface nanostructures below the surface of the sample.

A method of irradiating a target with a high power density irradiation beam is described. The method can use an irradiation system configured to output an irradiation beam through a vacuum window. The irradiation beam is scanned repetitively back and forth between two angular orientations of the irradiation beam as the irradiation beam strikes and traverses the vacuum window. The target is moved as the irradiation beam is scanned. The irradiation beam and the target are aligned. The scanning of the irradiations beam and the moving of the target are synchronized to each other. The scanning of the irradiation beam prevents localized overheating of the vacuum window and allows the irradiation beam to have a power density that would damage the vacuum window if the irradiation beam were not scanned.

Provided is a material-inspection system for planning a cutting pattern for a composite material sheet based on a detected defect. The system comprises one or more sensors to measure one or more material properties of the composite material sheet; a cutter assembly having a cutter tool to cut the composite material sheet; a control system comprising a processor and a storage medium comprising instructions, that when executed by the processor, configured to: obtain an initial cutting pattern for the composite material sheet, wherein the initial cutting pattern comprises a plurality of shapes to be cut; determine a defect in the composite material based on a sensor; determine a reject region in the composite material around the defect; shift one or more shapes of the plurality of shapes away from the reject region; and provide a revised cutting pattern based on the shifting to be cut by the cutter assembly.
