摘要:
A method of marking is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Liquid marking material, such as ink, is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

A device for the transport and/or metering of marking material includes a plurality of phased electrodes, for example formed on a substrate. An electrostatic traveling wave may be generated along the electrodes to sequentially attract particles of marking material, and thereby transport them to a desired location. The electrodes may be formed in a planar structure. A matrix interconnection scheme allows for reduced lead count.

A micro-machined movable light emitting assembly is formed on or from an undoped or pure III-V substrate or formed on or from a doped III-V substrate. The movable light emitting assemblies are to be actuated using force generators, to generate the various mechanical degrees of freedom depending on the type of stage suspension and actuation.

A micro-electromechanical bistable shutter display device is provided capable of being implemented for both small screen, high resolution devices and for large billboard-type displays. The micro-electromechanical shutter assembly has bi-stability characteristics which allow the use of only a holding voltage to maintain an image. The micro-electromechanical shutter assembly includes a shutter having petal-like shutter segments covering reflective or transmittive films. To expose the film in a particular shutter assembly, its shutter segments are moved from the horizontal to a vertical position using electrostatic attraction forces to “collapse” the torsionally-hinged shutter segments. The shutter assembly can have a number of segments, as long as the resulting shutter assembly shape can be stacked to form a dense 2D array.

A solid state laser array is multiplexed using an array of micromirrors to permit high resolution printing in a wide format. Each laser in the laser array and each micromirror in the mirror array is individually controlled. The laser array may be an array of VCSELs produced on a GaAs substrate.

A single pass color xerographic printing system with a single polygon, single optical system Raster Output Scanning (ROS) system has a dual wavelength laser diode source for the ROS which images the dual beams at a single station as closely spaced spots on a dual layer photoreceptor with each photoreceptor layer sensitive to or accessible by only one of the two wavelengths.
摘要:
Nonmonolithic laser arrays having lasing elements mounted on a composite support that enables accurate positioning and separation of the lasing elements, and that enables low thermal, optical, and electrical cross-talk. The support includes a low thermal diffusivity region surrounded by high thermal diffusivity regions which have defined mounting surfaces onto which the lasing elements mount. Heat generated in the lasing elements is conducted away by the high thermal diffusivity regions, while the low thermal diffusivity region reduces thermal cross-talk between the lasing elements. Beneficially, the support assists current flow to (or from) the lasing elements.

A full color xerographic printing system, either double pass or single pass, with a single polygon, single optical system Raster Output Scanning (ROS) system has a dual wavelength laser diode source for the ROS which images the dual beams at a single station as closely spaced spots or at two stations as closely spaced spots on a dual layer photoreceptor with each photoreceptor layer sensitive to or accessible by only one of the two wavelengths.
