    摘要: An assembly, for example in a gas turbine engine, includes a rotatable component supported by a bearing in a support structure. A sealing arrangement includes a non-rotating sealing ring which makes sealing contact with sealing features on the rotatable component. The non-rotating sealing ring is radially displaceable with respect to the support structure by means of ribs which engage axially facing support faces of the support structure. The non-rotating sealing ring is radially located by an outer, non-rotating, race of the bearing, by means of a locating surface on a locating body of the non-rotating sealing ring. As a result of this arrangement, the running clearance at the sealing arrangement can be maintained, despite radial displacement of the rotatable component with respect to the support structure, and despite thermal and mechanical deflections of the support structure.

    摘要: 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. The MoO2 and MoO2 containing thin films can be used in organic light-emitting diodes (OLED), liquid crystal display (LCD), plasma display panel (PDP), field emission display (FED), thin film solar cell, low resistivity ohmic contacts, and other electronic and semiconductor devices.

    摘要: 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.

    摘要: Example embodiments of the systems and methods of cell imbalance detection disclosed herein may prevent any cell of a multi-cell battery pack from exceeding over voltage conditions of the battery. In an example embodiment, automatic cell imbalance detection may be performed using two cells in series. The example embodiment determines the relative cell voltages. If a difference between the two cells of more than a certain threshold is detected, a cell balancing circuit may be activated to discharge the cell with the higher voltage. Example embodiments use no microprocessor, nor an ADC. An advantage of this approach over previous solutions is the relative knowledge of the cell voltages.

    摘要: 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 while achieving better wear resistance performance.

    摘要: 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.
