摘要: A novel, wide inkjet printhead and method of forming said inkjet printhead is disclosed, wherein a pattern of orifices are formed, using a step-and-repeat process, in a flexible tape using laser ablation or other suitable etching devices. The location of the orifices corresponds to where ink will be ejected from the inkjet printhead. The pattern of orifices may extend to any length without difficulty in aligning the orifices, since the tape may be continuous along the entire length of the printhead.

摘要: An apparatus and method for cooling a large-area, pass-through projection mask for excimer ablation. In a preferred embodiment, a laser-transparent window is spaced apart from the projection mask to provide a thermal escape path. The thermal escape path receives a liquid flow which is in direct contact with patterned masking material of the projection mask. The liquid, preferably deionized water, is caused to flow in a laminar fashion. The liquid intersects the laser energy of the excimer laser. In a second embodiment, the liquid flow is along the periphery of the patterned masking material.

摘要: A solder drop ejector is disclosed where a current through liquid solder in a channel flows in a direction opposite to the direction of current through a fixed conductor insulated from the channel. The magnetic fields generated repulse the solder toward an orifice to eject a droplet of solder. The dielectric layer separating the fixed conductor and the solder is formed of a film. The film may be made extremely thin, such as 0.1 microns, so that the necessary repulsion force generated by the oppositely flowing currents may be achieved with relatively low driving currents of 10-200 amperes. The thin dielectric film is not molded and is not required to provide mechanical support to a channel wall. Hence, the manufacturing of the resulting solder jet printhead is simplified and its reliability is improved.

摘要: Imaging systems and methods are described. In one aspect, an ink layer having an electrorheological fluid composition including a suspension of colorant particles dispersed in an electrically insulating carrier fluid is formed on a surface of an electrically insulating layer supported by an electrically conducting substrate. A charge image is projected onto the ink layer to selectively form charge-stiffened regions adhering to the electrically insulating layer and representing respective regions of the projected charge image. Non-charge-stiffened ink layer components are physically separated from the charge-stiffened regions.
