  • Patent number: 6759908
    Abstract: A high frequency power amplifier that can improve efficiency of an operation of a transistor without limiting any input-side higher harmonic load of an impedance matching circuit to a short-circuit load, and can increase reflection of higher harmonics. By adjusting line lengths and line widths of signal lines, a 2nd harmonic can be adjusted to be an open load (a reflected phase angle of &Ggr;in: 0-90°, the quantity of reflection: 0.6-1.0), and a 3rd harmonic is adjusted to be a short-circuit load (the reflected phase angle of &Ggr;in: 110-270°, the quantity of reflection: 0.6-1.0). With this input-side higher harmonic load of the impedance matching circuit, efficiency of transistor operation can be improved. By disposing a higher harmonic processing circuit closer to a transistor, a high frequency power amplifier with a shortened line length between the higher harmonic processing circuit and the transistor, and increased quantity of reflection of higher harmonics is produced.

  • Patent number: 5981833
    Abstract: The present invention relates to the field of producing hybrid seeds, and specifically relates to the application of certain cloned nuclear fertility restorer genes, which restore male fertility to cytoplasmic male-sterile plants. In particular, the present invention relates to an enriched or substantially isolated nucleic acid sequence comprising a nucleotide sequence that hybridizes at least under moderately stringent conditions to SEQ ID NOS: 1, 3 or 4 and restores male fertility to a cytoplasmic male-sterile plant; a vector comprising such a sequence; an organism, virus, seed, plant cell, and plant comprising such a vector; methods for the production of hybrid seed; a method of producing a variant of a cytoplasmic male-sterile plant, and a method of suppressing cytoplasmic male sterility, all of which make use of the aforementioned nucleic acid sequences.

  • Patent number: 5820194
    Abstract: An adjustable tray table for a motor vehicle is disclosed. A base is fixed to a dashboard in the vehicle, and a platform is attached to the base. The platform or tray table has two sides and a substantially flat surface, and is adapted for movement between an extended position and a retracted storage position. When in the retracted storage position the platform closely conforms to the contour of the vehicle dashboard, and projects outwardly therefrom when in the extended position. Slidably engaging rails are provided to controllably direct the platform between the active and retracted storage positions.

  • Patent number: 5568935
    Abstract: A recumbent cycle with improved steering and drive assemblies is provided. The recumbent cycle is of the tricycle type having two rear wheels spaced-apart and rotatably supported on an axle and a single front wheel. A frame assembly, including a seat disposed in a recumbent position and fixed to a tubular frame, is pivotally attached to the axle, and includes a forward mount for rotatably supporting the front wheel. A pedal/crank drive is included for rotating the front wheel and, therefore, propel the cycle. A steering assembly is also provided for pivoting and tilting the frame assembly with respect to the rear axle. The frame and the seat tilt into the turn as the frame is pivoted relative to the rear axle. The front wheel being carried on the frame assembly, pivots along with the frame assembly to effectively point the front wheel in the intended direction of travel, and therefore steer the cycle.
