Abstract: A method of cooling a heat source, such as an integrated circuit device, includes the following steps (1) providing a base having a plurality of elongated fins on a first side thereof and a mating surface on a second side thereof, with the plurality of elongated fins defining a plurality of channels, (2) positioning the mating surface of the base in contact with the integrated circuit device, (3) advancing a first flow of fluid onto a top surface of each of the plurality of fins so as to form a quantity of spent fluid which continues to be advanced into the plurality of channels, and (4) advancing a second flow of fluid into the plurality of channels so as to exhaust the quantity of spent fluid from the plurality of channels. An apparatus for cooling a heat source is also disclosed.

Abstract: Melt atomizing apparatus comprising a melt supply orifice for supplying the melt for atomization and gas supply orifices proximate the melt supply orifice for supplying atomizing gas to atomize the melt as an atomization spray. The apparatus includes a sensor, such as an optical and/or audio sensor, for providing atomization spray data, and a control unit responsive to the sensed atomization spray data for controlling at least one of the atomizing gas pressure and an actuator to adjust the relative position of the gas supply orifice and melt supply in a manner to achieve a desired atomization spray.

Abstract: High pressure atomizing nozzle includes a high pressure gas manifold having a divergent expansion chamber between a gas inlet and arcuate manifold segment to minimize standing shock wave patterns in the manifold and thereby improve filling of the manifold with high pressure gas for improved melt atomization. The atomizing nozzle is especially useful in atomizing rare earth-transition metal alloys to form fine powder particles wherein a majority of the powder particles exhibit particle sizes having near-optimum magnetic properties.
