| 20120060889 | Thermoelectric modules and assemblies with stress reducing structure - A thermoelectric module capable of minimizing thermally and physically induced stress includes a pair of substrates having a plurality of electrically conductive contacts disposed on opposing faces, a plurality of P-type and N-type thermoelectric elements interposed between the pair of substrates forming a thermoelectric element circuit, and one or more of a stress minimizing structural element interposed between the pair of substrates where the stress minimizing structural element has a first surface fixed to one of the pair of substrates and a second surface fixed to the other of the pair of substrates in locations between the pair of substrates that minimize the effects of physical and thermal stresses on the plurality of P-type and N-type thermoelectric elements. | 03-15-2012 |
| 20110232568 | HYBRID GAS INJECTOR - A gas injector for use in injecting process gas into a space in a vertical furnace between a tower supporting multiple wafers and a tubular liner includes a tubular straw having an open distal end and a first bore extending along a first axis and composed of a first single material selected from the group consisting of silicon, quartz, and silicon carbide, and a connector detachably connected to the straw section, composed of a second material other than the first material and including a supply tube having a second bore extending along a second axis perpendicular to the first axis and in fluid communication with the first bore and having a distal end connectable to a gas supply line. | 09-29-2011 |
| 20110073236 | HIGH STRENGTH BONDING AND COATING MIXTURE - A mixture includes a silicon compound having a polycarbosilane backbone, and a powder having a plurality of individual powder grains, wherein each of the plurality of powder grains has a diameter substantially between 0.05 micrometers and 50 micrometers. | 03-31-2011 |
| 20100272893 | Lift-off deposition system featuring a density optimized HULA substrate holder in a conical deposition chamber - A vapor deposition device using a lift-off process includes an evaporation source, a space frame mounted for rotation about a first axis that passes through the evaporation source, a central dome-shaped wafer holder mounted to the space frame wherein a centerpoint of the central dome-shaped wafer holder is aligned with the first axis, a orbital dome-shaped wafer holder mounted to the space frame in a position offset from the first axis and rotatable about a second axis that passes through a centerpoint of the orbital dome-shaped wafer holder and the evaporation source, and a plurality of wafer positions on the central dome-shaped wafer holder and the orbital dome-shaped wafer holder where each of the wafer positions are offset from the first axis and the second axis. Each of the plurality of wafer positions are configured to orient a substrate surface of a wafer mounted therein substantially orthogonal to a radial axis extending from the wafer position to the evaporation source during rotation about the first axis and the second axis. | 10-28-2010 |
| 20090038317 | Thermoelectric temperature-controlled container holder and method - A Thermoelectric-based container holder has a receptacle with a recess for receiving a container to be heated or cooled, a variable interface surface disposed within the holder and configured to flexibly contact an outside surface of the container to be heated or cooled where the variable surface interface is in thermal contact with the surface of the receptacle, and a thermoelectric assembly thermally connected to at least the variable surface interface. | 02-12-2009 |
| 20080211193 | Self-cooling ferrofluid seal - A method of cooling a ferrofluid seal that includes moving air from an atmospheric side of the ferrofluid seal over one or more heat dissipating surfaces within the ferrofluid seal through an air path formed in the ferrofluid seal by incorporating one or more vent openings in a housing case and one or more fan blades on a surface selected from the group consisting of an outside surface of a shaft and an inside surface of the housing case where the space surrounding the shaft communicates with the one or more vent openings and where the moving air is caused by the rotation of the surface having the one or more fan blades. | 09-04-2008 |
