Abstract: A field effect transistor with improved electrostatic discharge (ESD) protection has a source, a channel underlying a gate electrode and a drain. The drain includes a lightly doped ballast resistor extending across the width of the drain and separating two other drain sub-regions. One drain sub-region is located between the ballast resistor and the channel, the other drain sub-region is opposite the resistor and connected to an exterior device. The ballast resistor laterally distributes current along the width of the drain during an ESD pulse, which reduces local peak current density and reduces damage.

Abstract: In accordance with the process of the present invention, substantially complete removal of hydrogen fluoride values from a hydrogen chloride gas stream containing the same is effected by a process wherein the gas stream is contacted with an aqueous medium containing calcium chloride and hydrogen chloride under conditions sufficient to precipitate calcium fluoride, thereby producing a hydrogen chloride acid gas substantially free of hydrogen fluoride. The aqueous solution containing the calcium fluoride solids may be treated as by filtration to remove the solids and the recovered liquor may be recycled to the absorption stage, with optional addition of make-up calcium chloride, for removal of additional hydrogen fluoride.

Abstract: A device, method, and system for generating electric power and desalinating seawater, combining concentrated solar energy with one-or-more cogeneration alternatives; utilizing seawater as a working fluid. An inclined Fresnel-mirror-system of east-west primary axis, and site-latitude justification, is utilized to reflect the sun's incidental irradiance to a central receiving tube, and raising temperature of working-fluid therein, producing dry saturated, or wet steam, whereby resultant energy turns a rotary-screw-expander engine, providing mechanical power, thence turning a generator; producing electric power. Heat recovered in the working-fluid is utilized in seawater desalination using a Multi-Effect-Distillation system, whereby, during non-solar-dependent productive hours, a molten-salts Single-Temperature-Thermal-Energy storage system is utilized as a battery. Waste heat from industry, renewable, and conventional power systems, is recycled to generate electrical power utilizing an organ fluid in a rotary-screw-expander engine arrangement, within an Organic Rankine-Cycle process, and desalinate seawater, accordingly.
