Assignee:

Xerox Corporation - Stamford CT

International Classification:

B41J 2035

US Classification:

347 21

Abstract:

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.

International Classification:

B11J 2215

US Classification:

347 85

Abstract:

In a ballistic aerosol marking device or the like, marking material flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the provision of electrostatic marking material moving structures in or near the walls of the marking material reservoir. Marking material may be set into a continuous motion past the port and controllably extracted from the reservoir into the channel.

International Classification:

G02B 2600

US Classification:

359296

Abstract:

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.

International Classification:

B41J 2175

US Classification:

347 85

Abstract:

A ballistic aerosol marking device includes, marking material which flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the creation of a fluidized bed or aerosol of marking material in the reservoir. Gas flow together with mechanical or electromechanical assistance can be used to assist in the generation of the fluidized bed or aerosol.
