  • Patent number: 9496405
    Abstract: An object of an embodiment of the present invention is to provide a semiconductor device including a normally-off oxide semiconductor element whose characteristic variation is small in the long term. A cation containing one or more elements selected from oxygen and halogen is added to an oxide semiconductor layer, thereby suppressing elimination of oxygen, reducing hydrogen, or suppressing movement of hydrogen. Accordingly, carriers in the oxide semiconductor can be reduced and the number of the carriers can be kept constant in the long term. As a result, the semiconductor device including the normally-off oxide semiconductor element whose characteristic variation is small in the long term can be provided.

  • Patent number: 9475710
    Abstract: A point of use irrigation water fertigation system utilizes plasma production of nitrogen-bearing species. Soluble nitrogen-bearing species are generated using an atmospheric air plasma treatment of an irrigation water supply. A plasma is generated by a tube having an air intake. A high frequency generator generates atmospheric plasma. The end of the tube is placed above the surface of the irrigation water supply and the plasma emanating from the tube generates nitrogen species in the water. The non-thermal plasma discharge efficiently produces highly reactive radicals and NOx species that have impact on water chemistry including inactivation of microorganisms with high efficacy and accelerated removal of persistent organic pollutants such as perfluorinated compounds (PFCs) from water samples. Plasma ignition can be initiated with a low flow of helium gas injection. Upon ignition, the gas is transitioned to a helium/room air mix, immediately followed by a transition to ambient room air only.

  • Patent number: 9466888
    Abstract: An antenna feed with mode suppression includes a transition section, having a window for connecting to an output port of a waveguide and having inner and outer conductors forming a coaxial waveguide that couples energy from the waveguide into a horizontal TE11 mode in the coaxial waveguide. A polarizer section is coupled to the transition section and generates circular polarization from the horizontal mode of the transition section. A radiator section is coupled to the polarizer and provides an output signal for the antenna feed. The transition section includes an electrical short coupling the inner and outer conductors. The electrical short is disposed adjacent to the window of the transition section. A dielectric block is also disposed between the inner and outer conductors and adjacent to the electrical short along the axis of the coaxial waveguide. A surface of the dielectric block is coated with a thin film sheet resistance.
