摘要： An electro-mechanical grating device for diffracting an incident light beam has a base which defines a surface. A spacer layer is provided above the base, said spacer layer defining an upper surface of said spacer layer. A longitudinal channel is formed in said spacer layer. A plurality of spaced apart deformable ribbon elements are disposed parallel to each other and span the channel. The deformable ribbon elements define a ribbon structure which comprises at least one layer of a single material. The ribbon elements and the electro-mechanical grating device are formed so that charge build-up in layers of the electro-mechanical grating device can be avoided during operation of the device.

摘要： A printer having mechanically-assisted ink droplet separation and method of using same, for separating an ink meniscus from an ink nozzle orifice while clearing-away particulate matter from about the orifice. In a preferred embodiment of the invention, a heater surrounds an orifice formed by the nozzle, the orifice having an ink meniscus residing therein. As the heater heats the ink meniscus, surface tension of the ink meniscus decreases, thereby causing the ink meniscus to extend outwardly from the orifice to define an extended ink meniscus. A cutter, which is disposed near the orifice, includes a plate member disposed opposite an outside surface of the nozzle so as to define a passage between the outside surface and the plate member. The plate member has an opening aligned with the orifice and in communication with the passage. A gas pressure regulator in communication with the passage supplies pressurized gas into the passage, which gas flows along the passage an through the opening. As the gas flows through the opening, it impinges the extended ink meniscus to separate the extended ink meniscus from the orifice. As the extended ink meniscus separates from the orifice, it forms an ink droplet that travels to a receiver medium, so that an ink spot is placed onto the receiver medium. Moreover, as the gas flows through the opening, the gas clears-away particulate matter from about the orifice.

摘要： A method of continuously ejecting liquid includes providing a liquid ejection system that includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member that extends over at least a portion of the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. The compliant membrane includes an orifice. Liquid is provided under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate by a liquid supply. A drop of liquid is caused to break off from the liquid jet by selectively actuating the MEMS transducing member which causes a portion of the compliant membrane to be displaced relative to the liquid chamber.

摘要： A continuous liquid ejection system includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the MEMS transducing member extends over at least a portion of the liquid chamber and is free to move relative to the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member and a second portion of the compliant membrane is anchored to the substrate. The compliant membrane includes an orifice. A liquid supply provides a liquid to the liquid chamber under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate. The MEMS transducing member is selectively actuated to cause a portion of the compliant membrane to be displaced relative to the liquid chamber to cause a drop of liquid to break off from the liquid jet.
