Working fluid generator with induction heating coil
A working-fluid generator comprising an electrically conductive vessel that is surrounded by an inductive coil and has conductive, longitudinal members that extend through the vessel. A fluid inlet passes through a one-way valve. Fluid heated by the interaction between the inductive coil and the combination of conductive vessel and conductive, longitudinal members is converted to working fluid in the form of a gas that builds pressure in the air-filled space inside the vessel. Air in the pressurized gas is released through a valve, leaving a working fluid. This fluid is controllably released through a solenoid valve and into a conduit leading to a working-fluid-driven machine. A renewable-energy resource may be used to preheat the fluid to be introduced to the working-fluid generator. |

Solid state light sources with common luminescent and heat dissipating surfaces
A solid-state light source with LEDs contained in a light recycling cavity emits both light and heat from heat extracting light emitting elements which form the light recycling cavity. Eliminating appended heat sinks makes these light sources ultra lightweight. The light sources can be attached and supported by suspended ceilings without affecting the seismic properties of the ceiling. The heat extracting light emitting elements are combined with a reflector to make directional light sources, which can be attached to ceilings with small magnets. Because the heat extracting light emitting elements transfer the heat from the light source to the illuminated area there is no requirement for disturbing or penetrating the ceiling barrier to a heat sink on the plenum side of the ceiling. This enables a contiguous acoustic ceiling. Further, the light sources are made from non flammable materials and therefore do not affect the fire rating of the ceiling. |

Single oxide metal deposition chamber
Implementations described herein generally relate to metal oxide deposition in a processing chamber. More specifically, implementations disclosed herein relate to a combined chemical vapor deposition and physical vapor deposition chamber. Utilizing a single oxide metal deposition chamber capable of performing both CVD and PVD advantageously reduces the cost of uniform semiconductor processing. Additionally, the single oxide metal deposition system reduces the time necessary to deposit semiconductor substrates and reduces the foot print required to process semiconductor substrates. In one implementation, the processing chamber includes a gas distribution plate disposed in a chamber body, one or more metal targets disposed in the chamber body, and a substrate support disposed below the gas distribution plate and the one or more targets. |
