Increased tool utilization/reduction in mwbc for UV curing chamber
ActiveUS20070298362A1Avoid collectingHigh emissivitySemiconductor/solid-state device manufacturingCharge manipulationUV curingInjection port
A pump liner is used to direct a laminar flow of purge gas across a workpiece to remove contaminants or species outgassed or otherwise produced by the workpiece during processing. The pump liner can take the form of a ring having a plurality of injection ports, such as slits of a variety of shapes and / or sizes, opposite a plurality of receiving ports in order to provide the laminar flow. The flow of purge gas is sufficient to carry a contaminant or outgassed species from the processing chamber in order to prevent the collection of the contaminants on components of the chamber. The pump liner can be heated, via conduction and irradiation from a radiation source, for example, in order to prevent the condensation of species on the liner. The pump liner also can be anodized or otherwise processed in order to increase the emissivity of the liner.

Radiant heating controls and methods for an environmental control system
ActiveUS8600561B1Function increaseIncrease valueMechanical apparatusStatic/dynamic balance measurementPrediction algorithmsOptimal control
Embodiments of the invention describe thermostats that use model predictive controls and related methods. A method of controlling a thermostat using a model predictive control may involve determining a parameterized model. The parameterized model may be used to predicted ambient temperature values for an enclosure. A set of radiant heating system control strategies may be selected for evaluation to determine an optimal control strategy from the set of control strategies. To determine the optimal control strategy, a predictive algorithm may be executed, in which each control strategy is applied to the parameterized model to predict an ambient temperature trajectory and each ambient temperature trajectory is processed in view of a predetermined assessment function. Processing the ambient temperature trajectory in this manner may involve minimizing a cost value associated with the ambient temperature trajectory. The radiant heating system may subsequently be controlled according to the selected optimal control strategy.

A problem in the manufacture of filters using tubular membrane bundles is keeping potting material from flowing into the openings at the ends of the tubes. A preferred embodiment of a method for manufacturing a tubular membrane filter employs a non-contact heat source such as radiant heating to melt the tips of the tubular membranes. This prevents the migration of potting material into the tubes when the potting material is flowed into the ends of tube bundles during the manufacturing process for a filter.

Bowtie Nanoantennas and Methods of Using the Same
A pillar-nanoantenna array structure is fabricated with a substrate to which pairs of pillars are coupled, where the pillars are characterized either by a thermal conductance less than 0.1 μW / deg or by transparency and a height exceeding thickness by at least a factor of two. Metallic caps atop a neighboring pair of pillars are separated by no more than 50 nm. An image-capture structure may be formed by modifying reflectance of a portion of the structure by heating of the portion by electromagnetic radiation. The array may be plastically deformed by raster scanning an electron beam across the array, exciting plasmon modes in the conducting particles thereby inducing a gradient force between neighboring conducting particles, and deforming neighboring pillars in such a manner as to vary the spacing separating neighboring conducting particles. A technique of plasmon-assisted etching provides for fabricating specified planar pattern of metal outside a cleanroom environment.

The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.
