摘要： An improved ink jet printhead comprising upper and lower substrates that are mated and bonded together with a thick film insulative layer sandwiched therebetween. One surface of the upper substrate has etched therein one or more grooves and a recess which when mated with the lower substrate will serve as capillary filled ink channels and ink supply manifold, respectively. The grooves are open at one end and closed at the other. The open ends serve as nozzles. The manifold recess is adjacent the grooved closed ends. Each channel has a heating element located upstream of the nozzle. The heating elements are selectively addressable by input signals representing digitized data signals to produce ink vapor bubbles. The growth and collapse of the bubbles expel ink droplets from the nozzles and propel them to a recording medium. A recess patterned in the thick layer provides a flow path for the ink from the manifold to the channels by enabling the ink to flow around the closed ends of the channels and increase the flow area to the heating elements. Thus, the heating elements lie at the distal end of the recesses so that a vertical wall of elongated recess prevents air ingestion while it increases the ink channel flow area and increases refill time, resulting in an increase in bubble generation rate.
摘要翻译：一种改进的喷墨打印头，其包括上下基板，其与夹在其间的厚膜绝缘层配合并结合在一起。上基板的一个表面在其中蚀刻有一个或多个凹槽和与下基板配合的凹槽，分别用作毛细管填充的墨水通道和墨水供应歧管。槽在一端敞开，另一端封闭。开口端作为喷嘴。歧管凹槽与凹槽的封闭端相邻。每个通道具有位于喷嘴上游的加热元件。加热元件可以通过表示数字化数据信号的输入信号来选择寻址，以产生油墨蒸气泡。气泡的生长和坍塌从喷嘴中排出墨滴并推动它们到记录介质上。在厚层中图案化的凹槽通过使墨水能够围绕通道的封闭端流动并且增加到加热元件的流动面积而提供用于从歧管到通道的墨水的流动路径。因此，加热元件位于凹部的远端，使得细长凹槽的垂直壁防止空气摄取，同时增加墨通道流动面积并增加再填充时间，导致气泡产生速率的增加。

摘要： A thermal ink jet printer including a frame, a printhead mounted to the frame for printing ink images onto a heated and supported substrate, and an efficient substrate heating and supporting assembly mounted to the frame. The efficient substrate heating and supporting assembly includes a heating device, and a substrate supporting member having a front surface including a substrate supporting area for supporting substrates of various sizes one at a time and border areas having a polished finish. The efficient substrate heating and supporting assembly also includes a heat absorbing back surface facing the heating device. The heat absorbing back surface includes an increased heat absorbing area located opposite and centered relative to the substrate supporting area on the front surface. The increased heat absorbing area, relative to a rest of the back surface, has a coat of paint thereon for increasing heat absorption thereinto from the heating device, thereby resulting advantageously in relatively nonuniform heat absorption into the back surface, and relatively in more uniform, adequate and efficient substrate heating and drying temperatures on the front surface, when continuously running a most often run size of substrates.

摘要： A method and apparatus for controlling the volume of ink droplets ejected from printhead nozzles over a larger printhead operating temperature range. Each nucleating electrical pulse applied to the heating elements in the printhead to eject an ink droplet is preceded by a plurality of non-nucleating pre-pulses. Based upon the printhead temperature sensed, a controller selects the pre-pulse width and time width between pre-pulses from a look-up table.

摘要： The present invention is a multispot laser light source assembled from at least two individual laser diodes in accordance with a design model. The multispot laser includes at least two semiconductor laser diodes, both of which are permanently affixed to a chip carrier. The chip carrier rigidly supports the diodes and conducts heat away from the the diodes to be dissipated by a heat sink. The present invention is further characterized by a predefined relationship between the chip carrier material, the relative dimensions of the chip carrier, and the separation distance of the diodes from the heatsink, which results in significant reduction in the thermal droop and crosstalk between the diodes.

摘要： An ink jet printhead is disclosed which has a heater plate containing the heating elements and driving circuitry means monolithographically formed on one surface thereof and the ink flow directing channel structure is formed on the heater plate using a layer of patternable polymeric material which, in one embodiment, is exposed using a mask to define the channel pattern then developed and cured. After curing, the patterned channel structure is polished to provide a smooth coplanar surface and a cover plate with an aperture therein is aligned and bonded to the channel structure to complete the printhead. The aperture serves as both ink inlet and a portion of the ink reservoir. The channels are open at one end and serve as the droplet ejecting nozzles, while the other ends are closed and extend beneath the cover plate aperture to provide a baffled portion of the ink reservoir and prevent cross-talk between the ink channels. In another embodiment, the channels ends opposite the nozzles open into a common recess with the channels walls extending therein to function as baffles and prevent cross-talk.

摘要： A thermal ink jet printhead is disclosed having an ink channel geometry that controls the location of the bubble collapse on the heating elements. The ink channels provide the flow path between the printhead ink reservoir and the printhead nozzles. In one embodiment, the heating elements are located in a pit a predetermined distance upstream from the nozzle. The channel portion upstream from the heating element has a length and a cross-sectional flow area that is adjusted relative to the channel portion downstream from the heating element, so that the upstream and downstream portions of channel have substantially equal ink flow impedances. This results in controlling the location of the bubble collapse on the heating element to a location substantially in the center of the heating elements.
