  • Patent number: 6575558
    Abstract: A single-pass print head has multiple orifice plates each serving some but not all of the area to be printed. In embodiments, the printhead includes an array of ink jet outlets sufficient to cover a target of a print substrate at a predetermined resolution, and orifice plates, each of the orifice plates having orifices, each of the orifice plates serving some but not all of the area to be printed. The orifices are arranged in a pattern such that adjacent parallel lines on the print medium are served by orifices that have different positions in the array along the direction of the print lines, that are separated by a distance that is at least an order of magnitude greater than the distance between adjacent orifices in a direction perpendicular to the print line direction.

  • Patent number: 5543985
    Abstract: A suspension load beam for a rigid disk drive. The load beam has a central load beam member having a flexure supporting surface and an opposing surface, and rails disposed along the sides of the central member. The rails form channels extending away from the flexure supporting surface at a proximal end of the central member, and the rails extend away from the opposing surface at a distal end of the central member. The rails thereby have the advantageous characteristics of "upswept" rails at the distal end of the load beam while retaining the advantageous characteristics of "reverse" rails at the proximal end of the load beam.
