摘要： A micro-electromechanical device for controlling compressed fluid flow is provided. A chamber includes a fluid flow inlet port, a high pressure region exceeding 30 bar, and a fluid flow outlet port. A moveable micro-electromechanical valve is positioned to contact the fluid flow outlet port when the moveable micro-electromechanical valve is in a first position. An electrical connection to the moveable micro-electromechanical valve provides an electrical pulse train to the moveable micro-electromechanical valve to actuate the valve at a rate of 10 KHz or more to move the valve in order to control fluid communication between the high pressure region and a low pressure region downstream from the fluid flow outlet port.

摘要： A printhead includes a jetting module, deflection mechanism, and catcher. The jetting module includes a linear array of nozzles having a pitch and extending along a length of the jetting module. The jetting module is configured to form drops travelling along a first path from liquid jets emitted from the nozzles. The deflection mechanism is configured to cause selected drops to deviate from the first path and begin travelling along a second path. The catcher, positioned to intercept drops travelling along one of the first and second paths, includes a drop contact surface and a liquid removal conduit connected in fluid communication by a Coanda surface including a radial surface having an array of grooves extending in the same direction as that of the nozzles. The array of grooves has a pitch that is greater than the pitch of the nozzle array.

摘要： Preparing a flexographic member (60) includes providing a digital image and calculating a relief image based on the digital image. At least one stress-sensitive boundary region (11) adjacent to at least one image feature is identified and the relief image is created on the flexographic member. The depth (18) of at least a portion of a floor region (10) adjacent the at least one image feature is increased to provide a modified floor region.

摘要： A method for reducing curl in a stored photographic film which aids in preventing serious difficulties with downstream film transport and handling of the film. The film, which has been stored as a roll wound on a first core or mandrel is unwound from the first core and wound onto a second core or mandrel in a first direction. The film is then unwound from the second core to yield a traveling web portion. The traveling web portion is preheated to a predetermined temperature while being continuously delivered to a housing. The film is wound onto a third core or mandrel located within the housing in a direction opposite the first direction where it is maintained at about the same predetermined temperature.
摘要翻译：一种用于减少保存的照相胶片中的卷曲的方法，其有助于防止膜的下游胶片输送和处理的严重困难。已经被卷绕在第一芯或心轴上的卷存储的薄膜从第一芯展开并在第一方向上卷绕到第二芯或心轴上。然后将薄膜从第二芯展开，以产生行进的纤维网部分。行进的腹板部分被预热到预定的温度，同时被连续输送到壳体。该薄膜沿着与第一方向相反的方向卷绕在位于壳体内的第三芯或心轴上，在该方向上保持大约相同的预定温度。

摘要： A group timing delay device is provided to shift the timing of drop formation waveforms supplied to drop formation devices of nozzles of one of first and second groups so that print drops formed from nozzles of the first and second groups are not aligned relative to each other along a nozzle array direction. A charging device includes a common charge electrode associated with liquid jets formed from the nozzles of the first and second group and a source of varying electrical potential between the charge electrode and liquid jets. The source of varying electrical potential provides a charging waveform that is independent of print and non-print drop patterns. The charging device is synchronized with the drop formation device and the group timing delay device to produce a print drop charge state on print drops and a non-print drop charge state on non-print drops.
