  • Publication number: 20110074859
    Abstract: Disclosed are a roll-to-roll printing system and method in which a large number of micro-nozzles are formed directly in a printing roll, and thus ink supplied to the central portion of the roll can be formed into micro-inkjets by inducing an electrostatic field, and furthermore, as a result of the formation of the micro-inkjets, a micro-sized pattern significantly smaller than that achievable by a prior pattern formation method can be printed on a print medium, and in addition, the relative speed of the print medium relative to the roll can be maintained at a speed close to “0” so as to improve the resolution, integration density and precision of the printed pattern. According to the present invention, a large amount of micro-nozzles are formed directly in a printing roll, and thus ink supplied to the central portion of the roll can be formed into micro-inkjets by inducing an electrostatic field.

  • Patent number: 7897453
    Abstract: An integrated circuit including vertically oriented diode structures between conductors and methods of fabricating the same are provided. The diode is a metal-insulator diode having a first metal layer, a first insulating layer, a second insulating layer and a second metal layer. At least one asymmetric interface state is provided at the intersection of at least two of the layers to increase the ratio of the diode's on-current to its reverse bias leakage current. In various examples, the asymmetric interface state is formed by a positive or negative sheet charge that alters the barrier height and/or electric field at one or more portions of the diode. Two-terminal devices such as passive element memory cells can utilize the diode as a steering element in series with a state change element. The devices can be formed using pillar structures at the intersections of upper and lower conductors.

  • Publication number: 20100147593
    Abstract: In a dual-gradient drilling apparatus, a subsea solids processing unit includes a housing, a solids processing mechanism disposed in the housing between a drilling mud inlet and a drilling mud outlet, and a flushing mechanism configured to flush the solids processing mechanism with a flushing fluid. A subsea solids processing unit may be controlled by rotating the solids processing mechanism in a forward direction and increasing a drive torque when a measured speed of the solids processing mechanism is below a desired rotation speed. The desired rotation speed may be decreased when a measured torque exceeds a selected maximum and a rotation direction of the solids processing mechanism may be reversed when the measured speed falls below a selected minimum.

  • Publication number: 20090141032
    Abstract: A method for synchronizing an input data stream with an output data stream in a video processor. The method includes receiving an input data stream and receiving an output data stream, wherein the input data stream and the output data stream each comprise a plurality of pixels. The method further includes sequentially storing pixels of the input data stream using an input buffer and sequentially storing pixels of the output data stream using an output buffer. Timing information is determined by examining the input data stream and the output data stream. A synchronization adjustment is applied to the input buffer and the output buffer in accordance with the timing information. Pixels are output from the input buffer and the output buffer to produce a synchronized mixed video output stream.
