  • Patent number: 8152495
    Abstract: A mixed flow fan assembly includes an electric motor, an impeller having a hub enclosing the motor, and a plurality of fan blades spaced circumferentially around the hub. The fan assembly also includes an axis of rotation extending through the hub, an annular venturi radially surrounding the impeller, and a mounting plate with an opening to allow for axial airflow positioned on one open end of the venturi. The venturi has at least one elongated slot to allow for radial airflow from the fan assembly, the slot being oriented substantially perpendicular to the axis of rotation and having a generally rectangular shape. Rotation of the hub and the fan blades caused by the electric motor generates both axial and radial airflow through the fan assembly.

  • Patent number: 6724449
    Abstract: A liquid crystal display device includes a first substrate, a dry alignment film deposited over the substrate, a second substrate coupled to the first substrate with the dry alignment film deposited over the second substrate therebetween and forming a cell gap, and a liquid crystal material formed in the cell gap. The dry alignment film allows for a truly vertical alignment of molecules of the liquid crystal material such that the molecules form an angle of substantially 90° relative to the substrate. The dry alignment film can be an oxide layer, a nitride layer, an oxynitride layer or a silicon layer. This dry alignment layer can be treated to form a tilted homeotropic alignment, such that the liquid crystal molecules have a pretilt angle of 0.5 to 10 degrees from a substrate normal direction.

  • Patent number: 6641300
    Abstract: A method for calibrating thermal resistance and thermal capacitance parameters characterizing a DSC cell, and then calculating the heat flow to the sample based upon the results of the calibration. The method is applied in a conventional heat flux calorimeter, to obtain thermal analysis data having improved baseline and resolution. A first embodiment is based upon a model of a calorimeter in which there is no cross-talk between the sample and reference sides of a DSC cell. The thermal resistance and thermal capacitance parameters are calculated by carrying out a sequential series of calibration measurements with an empty DSC cell, materials on the reference side and materials on both the sample and reference sides. Another embodiment takes the existence of cross-talk between the sample and reference sides of the calorimeter into account.

  • Patent number: 6593586
    Abstract: A method is disclosed for forming an alignment layer for use in a liquid crystal cell layer for use in a liquid crystal cell using an ion beam source that includes the steps of: (1) providing a substrate having a surface; (2) providing an ion beam source that emanates an ion beam; (3) providing a mask layer disposed between the substrate surface and the ion beam source. The mask layer has at least two openings disposed between the ion beam source and the substrate surface. The shape and position of the openings reduce the irregularity of the beam exposure in a border region on the surface of the substrate resulting from the ion beam source. The present invention may be used in conjunction with substrate treatment using multiple sweeps with a single ion beam source, or with a substrate treatment using a single sweep with multiple ion beam sources. Also disclosed is an apparatus for practicing the disclosed method.
