The scanner has a scanning area occupying a maximum width and an active width defined by a scanning width limiting mechanism adjustable to a preselected width.

A mechanical sweeping unit has at least one sweeping device arranged on a guide that can be modified in such a way that the sweeping width of the sweeping unit is variable.

A mask scanning laser marker whose scanning width on a mask surface is variable and whose efficiency of marking is improved.

In the case of a semiconductor wafer, the translation velocity in the beam scan width are controlled to produce an approximately circular scan pattern.

An apparatus records data by scanning an exposure beam across a film by a scanning width control signal in accordance with an input signal.

DEIMOS-1 boasts a sensor that captures images with a swath width of 620 km.

The SK 600 has a sweeping width of 2,300 mm, with the full width being swept mechanically.

A toner pattern is formed over a whole mask substrate by electrophotography by scan-and-step drawing with a resolution improved by limiting the scanning width of the laser beam used.

In this way, the bristles (3) on the ends of the agitator (20) are provided with a outwardly swept configuration that increases the effective swept width of the agitator (20).
