    摘要： A highly dislocation free compound semiconductor, e.g. AlxInyGa1-x-yN (0≦x, y≦1), is formed on a lattice mismatched substrate, e.g. Si, by first depositing a polycrystalline buffer layer on the substrate. A defective layer is then created at or near the interface of the substrate and the polycrystalline buffer layer, e.g. through ion implantation. A monocrystalline template layer of the compound semiconductor is then created on the buffer layer, and an epilayer of the compound semiconductor is grown on the template layer. A compound semiconductor based device structure may be formed in the epilayer.

    摘要： An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A check valve is disposed between the directional control valve and the source of fluid, only allowing fluid flow from the fluid source to the directional control valve. A bleed orifice may be disposed between the directional control valve and the source of fluid, in parallel with the check valve.

    摘要： The brushless DC motor of the present invention comprises a permanent magnet rotor rotating coaxially with and inside of the stator containing the electric windings, separated by a radial, axially extending gap. The rotor can be formed of four or more permanent, e.g., ferrite ceramic magnets, spaced substantially equidistantly circumferentially around the rotor and extending radially along the axial length of the rotor. The preferred ferrite magnets are substantially corrosion resistant, and thus durable in the wet rotor environment, in which it may be used, sufficient to withstand the effects of even hot salt water. Preferably, four of the permanent magnets are bar magnets, i.e., rectangular in cross-section, extending radially and perpendicularly to the adjacent magnets. Most preferably, the bar magnets are separated by generally wedge-shaped, or quadrant-shaped, sections of magnetic material. The permanent magnets are polarized so that the north-south flux lines extend transversely to each adjacent magnet, most preferably forming a so-called Halbach Array. This brushless DC motor is especially useful for driving wet rotor pumps, wherein the particular combination of elements forming the rotor results in a highly efficient, effective and durable motor.
