A micro-spray cooling system beneficial for use in testers of electrically stimulated integrated circuit chips is disclosed. The system includes micro-spray heads disposed about a probe head. The spray heads and probe head are disposed in a sealed manner inside a spray chamber that, during operation, is urged in a sealing manner onto a sealing plate holding the integrated circuit under test. The atomized mist cools the integrated circuit and then condenses on the spray chamber wall. The condensed fluid is pumped out of the chamber and is circulated in a chiller, so as to be re-circulated and injected again into the micro-spray heads. The pressure inside the spray chamber may be controlled to provide a desired boiling point.

Spray cooling thermal management system and method for semiconductor probing, diagnostics, and failure analysis

A system for probe-less non-invasive detection of electrical signals from integrated circuit devices is disclosed. The system includes an illumination source, collection optics, imaging optics, and a photon sensor. In a navigation mode, the light source is activated and the imaging optics is used to identify the target area on the chip and appropriately position the collection optics. Once the collection optics is appropriately positioned, the light source is deactivated and the photon sensor is used to detect photons emitted from the chip. No mention of cooling (active device measurement capability) and advanced optics to detect the features (SIL).

A telecommunications closure (1) includes a pressure clamp (21) for sealingly clamping mating parts (47, 48) of the closure together so as to form a water tight seal. The clamp member requires no tools during installation and creates no uncertainty as to the generation of appropriate clamp pressure on a sealing O-ring when installed. The pressure clamp includes an over-center latch which is rotatable between a first unlatched position and a second latched position, a clamping pressure generated by the latch increasing to a maximum value as the rotatable latch is moved from its first position to an intermediate position between the first and second positions and then decreases from this maximum value as the latch is moved from the intermediate position to the second position so as to generate a predetermined appropriate clamping pressure when in its second position so as to appropriately compress the O-ring disposed within a groove between the closure parts at their mating area.

An optical fiber splice tube holder includes a plurality of torsion bars and cantilever bars which provide a resilient retaining force for an optical fiber splice container to be retained therein. The use of torsion bars helps distribute stress generated by a spring force of the fiber splice member holder about a large amount of material so as to achieve an efficient spring construction so that a plurality of splice holders can be accommodated in a reduced space on a fiber storage tray.

A dryer for paper and similar fibrous web materials including a dryer roll having an outer cylindrically-shaped wall, a radiant heat source within the dryer roll adapted to heat the wall substantially uniformly about the entire periphery thereof, and nip-forming means forming a pressure nip with the dryer roll.

Apparatus and method for drying fibrous web material

Zone-controlled radiant burners are provided for retrofit installation in existing heaters. The burners comprise hollow cylindrical fiber matrix layers with baffles forming separate plena. A main stream of pre-mixed fuel and air is directed into the middle plenum, with the mixture flowing through the fiber matrix layer and incandescently combusting on the active surface zones to radiantly heat the tube coils. A reduced flow of fuel/air mixture, or only air, is directed into the remaining plenum so that the surrounding surface zones are combustibly less active or inactive to avoid destructive overheating of the burner surfaces.

Heater with zone-controlled radiant burners

A segmented radiant burner assembly for installation in the combustion chambers of firetube boilers and the like. The individual segments can be assembled together for on-site installation within the boiler. The segments include support structures comprising mounting flanges which are secured together in series to form the burner assembly. Gas and thermal sealing between the active material of the burner and the inactive support structure is provided by a sealing system which includes a dense fiber composition material and adhesive agent of ceramic composition. The mixture of unburned reactants is directed through a valving and manifold system into separate plena within the burner segments. The flow rates of reactants to the different burner segments is selectively controlled in a sequence which achieves a broad firing rate range.
