  • Patent number: 12291099
    Abstract: For a vehicle interior compartment defined by a vehicle floor, opposing sidewalls, a forward end and a rearward end, and a vehicle ceiling covering at least part of the compartment, an end zone overhead display structure includes bulkhead forming attachment elements coupled to a roof strut spanning from sidewall to sidewall of the vehicle roof. The display structure includes an open box-like upper bracket and an open box-like lower bracket coupled together with the roof strut interposed to provide an assembly that reduces unwanted motion, rotation or vibration of the display assembly.

  • Patent number: 12258072
    Abstract: A vehicle hood assembly can include a vehicle body structure and a hood moveable with respect to the vehicle body structure from a closed state to an opened state. A first linkage can connect the hood to the vehicle body structure and include a first linkage aperture extending therethrough. A second linkage can connect the hood to the vehicle body structure and include a second linkage aperture extending therethrough. A central axis of the first linkage aperture can be coaxial with a central axis of the second linkage aperture if the hood is in the opened state. A key structure can be provided and configured to simultaneously fit into both the second linkage aperture and the first linkage aperture if the hood is in the opened state.

  • Patent number: 12203308
    Abstract: A hood for a vehicle is movable between an open position and a closed position for covering a vehicle compartment. The hood includes a hood body having an exterior facing surface and an interior facing surface. A first bracket attached to the interior facing surface of the hood body includes a bottom end having a downward opening slot a rotatable hinge attached to the vehicle in the vehicle compartment for moving the hood body between the open position and the closed position. A second bracket is attached to the vehicle in the vehicle compartment. The second bracket is attached to a distal end of the rotatable hinge and includes a weld stud extending laterally from a side of the second bracket. The first bracket is seated on the weld stud during installation of the hood.

  • Patent number: 7112913
    Abstract: A method for manufacturing a surface acoustic wave apparatus to be mounted via bumps by a flip chip bonding system prevents peeling of electrode pads from the piezoelectric substrate and cracks in the piezoelectric substrate from occurring during the formation of the bumps or at other times during the manufacturing process. In the method of manufacturing a surface acoustic wave apparatus, a first electrode layer of the electrode pad is formed on a piezoelectric substrate by etching, an electrode for a surface acoustic wave element is formed by a lift-off method after the first electrode layer is formed, and thereafter, an electrode film including a second electrode layer of the electrode pad and a wiring electrode is formed.

  • Patent number: 6458675
    Abstract: A semiconductor device includes: a semiconductor substrate; an active layer; and a plasma-processed layer provided between the semiconductor substrate and the active layer. The plasma-processed layer has a deep level. First and second electrodes are electrically connected by ohmic contact with first and second portions of the active layer, respectively. The first and second portions are spaced apart at a predetermined interval from each other. A third electrode is formed on a third respective portion of the active layer and is located between the first and second portions of the active layer.
