  • Patent number: 10828890
    Abstract: In an embodiment of the present invention, even though there is a print shift due to a gap between a nozzle in an upstream side and a nozzle in a downstream side of a printhead, a printing apparatus capable of precisely adjusting a slant of a printhead with respect to a conveyance direction in a nozzle surface of the printhead is provided. According to the embodiment, two adjustment patterns are printed at two different carriage speeds, respectively, and a print shift due to a slant of the nozzle surface of the printhead with respect to a conveyance direction of a print medium is adjusted based on these two print results.

  • Publication number: 20180317016
    Abstract: A magnetic-field-generating unit and a coil vibrates an armature. The armature drives a diaphragm. The armature is formed of a rolled metal plate made of Permalloy. A workpiece is cut out of an unannealed metal plate with a wire saw or by etching such that the long-side direction of the workpiece corresponds to a transverse direction that is orthogonal to the direction of rolling performed on the metal plate. The cut-out workpiece is bent and is then annealed. Through this process, the warp of the armature is minimized.
