  • Patent number: 7754185
    Abstract: The invention relates to high purity MoO2 powder by reduction of ammonium molybdate or molybdenum trioxide using hydrogen as the reducing agent in a rotary or boat furnace. Consolidation of the powder by press/sintering, hot pressing, and/or HIP is used to make discs, slabs, or plates, which are used as sputtering targets. The MoO2 disc, slab, or plate form is sputtered on a substrate using a suitable sputtering method or other physical means to provide a thin film having a desired film thickness. The thin films have properties such as electrical, optical, surface roughness, and uniformity comparable or superior to those of indium-tin oxide (ITO) and zinc-doped ITO in terms of transparency, conductivity, work function, uniformity, and surface roughness.

  • Publication number: 20100025936
    Abstract: A leaf seal arrangement is provided in which within a housing there are edge portions to inter associate with non parallel chamfer edges in leaf seal elements. In such circumstances, deflection of the leaf seal elements in an outward direction or inward direction relative to a rotating shaft creates variation in a control gap X, XX between the edges and the chamfer edge. Such increase or decrease in the control gap X, XX adjusts the aerodynamic radial force that is presented to the leaf seal elements whereby those elements can be more accurately maintained at a desired leaf position for optimizing leakage whilst achieving better wear resistance performance.

  • Patent number: 7159872
    Abstract: A seal arrangement (73) is provided in which seal elements (77) incorporate passages (90) allowing an air flow to be presented to tip edges (78) of the seal elements, in order to create air suspension and diminish excessive wear. These passages (90) are created by recesses in the respective adjacent juxtaposed seal elements (77). In a seal assembly (71) a seal arrangement (73) is secured within a float chamber (70) whereby radial movement is allowed to accommodate for movements in the shaft (72). The radial movement is resisted by a bias created by air flow (86) into the float chamber (70). The air flow (86) may also be presented through the passages (90) in order to create the desired air suspension of the seal elements (77).

  • Patent number: 6911896
    Abstract: A resistor string that may have two resistor matrices laid out back-to-back with selected or all nominally equipotential nodes of the two matrices being interconnected. In certain applications, the matrix may have switch connections at each node, with the second matrix being an inactive matrix that may have the same number or different number, typically fewer resistors than the first matrix. In another embodiment, separate matrices may be used, and the inactive matrix may be smaller and have fewer resistors of a lower value to minimize the effect of gradients across the substrate. Preferred matrices and node connection switch configurations, as well as various embodiments of these and other features of the invention are disclosed.

  • Patent number: 6859091
    Abstract: Continuous linear regulated zero dropout charge pump with high efficiency load predictive clocking scheme AND method. The method of pumping charge includes amplifying the difference between a feedback signal from the charge pump output and a reference, and alternately switching between: a) coupling a first flying capacitor between first and second power supply terminals, and coupling a second flying capacitor between the amplified difference and the charge pump output; and b), coupling the second flying capacitor between first and second power supply terminals, and coupling the first flying capacitor between the amplified difference and the charge pump output. Preferably the switching is done before the amplifier saturates. Various alternate embodiments and method and apparatus for starting the charge pump are described.

    Abstract: The present invention relates to compositions comprising a structured benefit agent pre-mix or delivery vehicle comprising benefit agent structured with crystalline materials, as defined, which when separately prepared and combined after preparation, provides enhanced delivery of benefit agent from a personal product bar carrying composition into which the premix is added. The use of structured benefit agent also enhances delivery of separate benefit agents in the premix (which may or may not be structured) and of separate benefit agents added separately from the premix.

  • Patent number: 6803799
    Abstract: A low power, high speed D type flip flop is disclosed. The D type flip flop uses four inverters and four transmission gates to store and output the data states. The flip flop comprises two memory elements wherein each memory element is made up of a transmission gate and two inverters. Each of the four inverters contained in the flip flop is referred to as a bypass current limiting inverter. Each of the four inverters contains biasing circuitry to limit current flow and thereby save power. Additionally, each inverter has switching circuitry that enables the current limiting features to be automatically and advantageously bypassed thereby allowing for large currents and fast response times whilst simultaneously retaining the low power performance.

  • Publication number: 20030020594
    Abstract: Enhanced linearity, low switching perturbation resistor string matrices. The resistor strings are arranged in an array of a plurality of rows of resistive elements and electrically arranged with rows equally spaced above and below the physical centerline of the array being coupled together in an opposite sense. Preferably also physically adjacent rows are equally spaced from the center of the electrical order of rows. This connection prevents accumulation of errors due to vertical and horizontal resistance gradients over the array. Also node selection by controlling node select transistors coupled to column select lines to select one node in each row, and also controlling row select transistors to select the row of the desired node minimizes settling time after a tap change by inducing equal and opposite voltage changes at points close together along the resistor string, whether in the array of the present invention or in the snake configuration.
