Abstract: A method of forming a gate of a split-gate trench MOSFET in an epitaxial layer is provided, the epitaxial layer includes a source polysilicon rib which extends perpendicularly to a plane of the layer; providing trenches on either side of an upper portion of the source polysilicon rib, with inner walls of the trenches formed by a deposited insulator, providing mask material which extends into the trench, providing photoresist on the epitaxial layer and using photolithography to pattern the photoresist, using the photoresist to etch the insulator, a portion of the insulator in contact with the source polysilicon is protected from etching by the mask, removing the mask and forming trenches on either side of the source polysilicon, each trench having an inner wall formed by the insulator which was protected from etching providing an insulator on the epitaxial layer, and providing a bar of gate polysilicon in each trench.

Abstract: This disclosure describes techniques for analyzing flights and identifying opportunities to provide flights to passengers that might not otherwise be made available. Benefits of these systems and methods may include filling more seats in aircraft that would otherwise go unfilled providing more flight opportunities to passengers as well as increasing opportunities to sell more flights for operators of the aircraft. For example, a charter operator might increase revenue through marketing automation and increased marketing reach they could otherwise not access themselves. Additionally, the system may provide tools for marketing and monetizing an operator's unused aircraft capacity. Additionally, the system may provide tools to move aircraft to areas where a demand will be, for example, by generating and selling flights that move the aircraft in that direction over the time leading up to the demand.

Abstract: The present invention is an apparatus arranged to maximize heat utilization for a hydrocarbon steam reforming process to produce synthesis gas. The apparatus comprises a refractory lined vessel with partition walls that divide the inside of the vessel into (1) a combustion chamber(s) containing one or more burners, and (2) convection chambers used as a means to remove combustion products from the combustion chamber through one or more openings at the opposite end of the burner end. The combustion chamber contains one or more reformer tubes in which a mixed-feed of hydrocarbon and steam flow co-current with combustion products and receive direct radiant heat from the combustion flame through the tube wall. The convection chambers contain a tube-in-tube device filled with catalyst in the annuli.
