    • PROBLEM TO BE SOLVED: To provide a method and apparatus of printing wherein fluid droplets are introduced into an airflow outside a region of the highest airflow velocity.
      SOLUTION: A multirow multinozzle continuous inkjet head comprises a plurality of rows of inkjet nozzles ejecting droplets in regions of airflow velocity within a collinear airflow. The airflow velocity at all nozzles is equal, but lower than the highest airflow velocity within the collinear airflow. This allows many more droplet flows to be placed in a velocity-matched airflow. Despite the droplets being arranged in regions with air velocity gradients across the droplets, the lateral forces are such that droplet placement on a print medium surface is accurate and well controlled.

    • 要解决的问题:提供一种打印方法和装置,其中将流体液滴引入最高气流速度区域外的气流中。 解决方案:多重多喷嘴连续喷墨头包括多行喷墨喷嘴,其在共线气流中的气流速度区域中喷射液滴。 所有喷嘴的气流速度相等,但低于共线气流中最高气流速度。 这允许将更多的液滴流放置在速度匹配的气流中。 尽管液滴布置在跨越液滴的空气速度梯度的区域中,但是横向力使得在打印介质表面上的液滴放置是准确和良好的控制的。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a scanner in which the mass of a moving head is small and high speed scanning is possible when a flat material is scanned. SOLUTION: A high speed scanning axis for a high speed flatbed scanner has a long reciprocal motion table for fixing a material to be scanned. The width of a table is smaller than the material and part of the material projects from the table. The projected part is supported by a fixing and supporting face provided with a plurality of air jetting ports on the surface which give an air bearing face for the projected part. Thus, the moving mass of the scanner is kept small and the high speed scanning of the material is made possible. COPYRIGHT: (C)2004,JPO&NCIPI
    • 要解决的问题:提供一种扫描仪,其中移动头的质量小,并且当扫描平面材料时可以进行高速扫描。

      解决方案:高速平板扫描仪的高速扫描轴具有用于固定要扫描的材料的长的往复运动台。 桌子的宽度小于材料,材料的一部分从桌子上投影。 突出部分由固定和支撑面支撑,该固定和支撑面在表面上设置有多个空气喷射口,为喷射部分提供空气轴承面。 因此,扫描器的移动质量保持较小,并且材料的高速扫描成为可能。 版权所有(C)2004,JPO&NCIPI
