  • Patent number: 11935728
    Abstract: In order to reduce the occurrence of current alarms in a semiconductor etching or deposition process, a controller determines an offset in relative positions of a cover ring and a shield over a wafer within a vacuum chamber. The controller provides a position alarm and/or adjusts the position of the cover ring or shield when the offset is greater than a predetermined value or outside a range of acceptable values.

  • Patent number: 10141019
    Abstract: An optical disc drive (ODD) including a housing, a tray, a panel, a first linkage, and a second linkage is provided. The tray is movably disposed at the housing to move into or move out of the housing. The panel is connected to the tray and located at a side of the housing. The first linkage is rotatably disposed on the panel and located between the housing and the panel. The second linkage is rotatably disposed on the panel and located between the first linkage and the panel. By rotating the first linkage with respect to the panel in a first rotating direction, the second linkage is pushed by the first linkage and rotates with respect to the panel in a second rotating direction opposite to the first rotating direction so as to actuate the tray to move out of the housing.

  • Patent number: 7842634
    Abstract: A useful partial oxidation catalyst element includes a catalyst component, a support component, and a substrate. The catalyst component is formed by combining a catalytically active metal with a first support material to form a mixture and calcining the mixture. The support component is formed by calcining a second support material, not containing the active metal. The first and second support materials include particles having an average particle diameter of less than 20 microns. A catalyst material is formed by combining the catalyst component and the support component, wherein the catalyst material contains less than 20% of the catalyst component by weight. The catalyst material is applied to a substrate configured for gas flow therethrough, thereby formulating the partial oxidation catalyst element. The partial oxidation catalyst element is especially useful for fuel reforming and fuel cell applications.

  • Publication number: 20100101214
    Abstract: In an internal combustion engine system having an exhaust aftertreatment system including a selective catalytic reduction (SCR) catalyst, diagnostic methods involve the intrusive perturbation of a target surface coverage parameter theta to determine the state of health of the SCR catalyst or an ammonia concentration sensor. An adaptive learning block adapts the target theta based on the use of NH3 sensing feedback from a mid-brick positioned ammonia concentration sensor to pull in system variation. A further diagnostic monitors the amount of adaptation and when the adaptive learning excessively learns, the diagnostic assumes that some system-level degradation must have occurred and the diagnostic will notify the overall emissions control monitor.

  • Publication number: 20100101215
    Abstract: An exhaust gas treatment system includes a selective catalytic reduction (SCR) catalyst and a dosing control responsive to exhaust gas operating conditions for controlling the dosing rate of a reductant such as aqueous urea into the exhaust stream. The dosing control is configured to reduce the dosing rate when either a sudden increase in the exhaust mass air flow is detected or when an exhaust gas temperature gradient is in an increasing state. The dosing control is also configured to shut-off dosing when a measured ammonia concentration level exceeds an ammonia slip trip level, provided that the exhaust gas temperature gradient is also in an increasing state.
