    摘要: A nitride layer is deposited over a field oxide layer used to separate transistors formed in a substrate, the nitride layer serving to decrease transistor current leakage. The nitride layer has a dense lattice, effectively blocking H+ and Na+ penetration from overlying layers into the field oxide. Positive ions such as H+ and Na+ penetrating into the field oxide layer cause a p-substrate under the field oxide layer to become inverted or act like an n-type substrate, creating leakage current between source and drain regions of transistors which the field oxide layer separates. When high transistor threshold voltages such as 12 volts or more are desired, the nitride layer provides a significant reduction in current leakage.

    摘要: A method for improving the endurance and reliability of a floating gate transistor often used in memory applications by controlling the electric field induced across the tunnel oxide region of the floating gate when discharging electrons from the floating gate. The method comprises the steps of: allowing the active region to ground; and applying a program voltage to the floating gate over a period of time and at a magnitude, by increasing the voltage from zero volts to the magnitude over a first period of at least 1 millisecond (ms.), maintaining the voltage at the magnitude for a second period of around 10 ms.-100 ms. sufficient to place charge on the floating gate, and decreasing the voltage from the magnitude during a third period to zero volts in not greater than 50 microseconds.

    摘要: This invention relates to a continuous flow centrifugation device and method of using the device for separation of solids, particles, liquids, or gases from a mixture containing them. The device contains rotating separation chamber in which incoming material in continuously enters the chamber via an inlet and the separated materials continuously flow out via two outlets. Solids or heavier materials exit from an outlet tubing, whose opening is placed in a space that is farthest from the center of rotation and has the highest centrifugal force. The liquid/supernatant outlet is placed in the space that is closer to the center of rotation with the lowest centrifugal force. The reference of placement of inlet to solids outlet is in the same direction as the direction of rotation so that the flow of incoming material, directed from inlet to solids outlet, is in the same direction as the direction of rotation. All product contact surfaces can be disposable and diverse separation methods for different applications can be executed in a fully automated or manual manner by a controller that manages different inputs and outputs of system components.

    摘要: The most common automated search methods produce less-than-ideal results when searching online resumes, profiles, and the like (“biographies”) for the identities of people with a searcher-selected qualification (“candidates”). Keywords, their proximities, and their repetitions are less informative in biographies than in other informational documents. Similarly, chains of social connection (“referral paths”) do not always reveal the likelihood or ease of a searcher's introduction to a candidate. In both cases, the display order of results may be unrelated to any estimate of merit. To answer the question “Whom do I need and how do I reach them?” a classifier system uses heuristics or algorithms adapted to match the reactions of human experts on the selected qualifications. Terms in biographies, regardless of structure, are standardized and disambiguated for accurate comparisons, meaningful context is preserved, and biographies and referral paths are scored based on expected usefulness to the searcher.
