    摘要: A phototypesetter font disk has a plurality of circumferentially spaced, optically readable indicia and a strobe track radially spaced from the indicia which contains a plurality of circumferentially spaced timing marks. Each indicia has an associated timing mark that is both radially and circumferentially spaced from its respective indicia. The strobe track has an identifiable reference location from which each indicia timing mark is angularly spaced. Additional marks are interposed between the indicia timing marks on the strobe track to define digital data relating to the font disk. Typically, such data includes font identification information.

    摘要: A correction element assembly for correcting misalignment of a beam of radiation with respect to a location on a target includes a correction element housing, and first and second piezo elements. The correction element is fixedly mounted in the housing and moveable therewith. The piezo elements are supported by a member having a first portion and a second portion. The first piezo element is mounted to the first portion of the member and to said housing, and moves the housing in a first direction. The second piezo element is mounted to the second portion of the member and to a base, and moves the housing in a second direction substantially perpendicular to the first direction.
