  • Patent number: 6526675
    Abstract: A method of dewatering fine particulate materials is disclosed. In this method, an aqueous slurry of fine particles is treated with appropriate hydrophobizing reagents so that the particulate material becomes moderately hydrophobic. A lipid of vegetable or animal origin is then added to the slurry in solutions of light hydrocarbon oils and short-chain alcohols, so that the hydrophobic lipid molecules adsorb on the moderately hydrophobic surface and, thereby, greatly enhance its hydrophobicity. By virtue of the enhanced hydrophobicty, the water molecules adhering to the surface are destabilized and more readily removed during the process of mechanical dewatering. The moisture reduction can be further improved using appropriate electrolytes in conjunction with the lipids, spraying surface tension lowering reagents onto the filter cake, subjecting the cake to a suitable vibratory means, and using combinations thereof.

  • Patent number: 6473993
    Abstract: A semiconductor wafer is mounted on a susceptor disposed in a processing chamber, the wafer is heated at a temperature on the order of 1000° C. for annealing, and a gas is supplied from a gas supply device disposed opposite to the wafer. When raising the temperature of the wafer and/or when lowering the temperature of the wafer, intra-surface temperature difference is limited to a small value to suppress the occurrence of slips. A gas supply device is divided into sections corresponding to a central part and a peripheral part, respectively, of the wafer to supply the gas at different flow rates onto the central part and the peripheral part, respectively. When raising the temperature of the wafer, for example, a gas of a temperature higher (lower) than that of the wafer is supplied at a flow rate per unit area greater (lower) than that at which the gas is supplied to the peripheral part to the central part.

  • Patent number: 6408537
    Abstract: A method and apparatus is disclosed for staging or cooling a substrate between high temperature thermal processing steps. In the disclosed embodiment, one or more cooling stations are located off-line within a wafer handling chamber, outside the thermal processing chamber. After thermal processing, a hot wafer can be loaded on to one station, where the wafer is subjected to forced convection cooling. In particular, the wafer is subjected to cooling gas from above and below through perforated upper and lower showerhead assemblies. The wafer can thus be cooled rapidly on a station while other wafers are transferred into and out of the processing chamber, Desirably, the wafer is cooled on the station to a point at which it can be handled by a low temperature wafer handler and stored in a low temperature cassette.

  • Patent number: 6402856
    Abstract: A system for stripping an optical fiber includes a source air, and means for generating very short bursts of air. A heater heats the bursts of air to a temperature sufficient to remove the outer coating from an optical fiber, while maintaining the air isolated from the heat source. The heater includes a heater core that includes a heat generating element such as a conductive filament, and a heat chamber enclosed within the heater core. A spiral-shaped air conduit surrounds the outer surface of the heater core, and communicates with the heat chamber. Upon injection of air into the conduit, heat is transferred to the air from the heat generating element while the air flows through the air conduit and into and out of the chamber. A single burst of heated air removes the outer coating of an optical fiber, within less than one second.
