    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.

    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: A switching element defines a transmitting state and a reflecting state for a pair of intersecting waveguides that have a gap at their intersection. In the preferred embodiment, the switching element exhibits total internal reflection at the gap sidewall from one waveguide to the other when not in the transmitting state. In the transmitting state, index-matching liquid fills the gap, enabling light to continue in the original waveguide direction. The switching element may use ink jet techniques or bubble techniques to displace index-matching liquid. The index-matching fluid may be projected from a gap between the waveguides by a jet mechanism, or a vapor or dissolved gas bubble may be formed to fill the gap between the waveguides to provide the reflecting state for the switching element. Using either of the techniques, heaters are employed to initiate the switching operation. In some embodiments, more than one heater is utilized. In the preferred embodiment, waveguides are formed on one substrate and heaters are formed on another. Then the substrates are aligned and bonded together to position the heaters in very close proximity to the intersection between the waveguides. Preferably, the switching element is one element in a matrix of such elements for routing signals between arrays of input and output waveguides.
