    摘要： According to one embodiment, the present invention provides a rotor assembly. The exemplary rotor assembly includes a plurality of rotor laminations, which cooperate to form a rotor core, capped at each end by end members. Extending through the rotor core and the end members, a plurality of rotor channels is configured to receive electrically conductive members therethrough. Each of the electrically conductive members has external portions, which extend beyond the rotor channel, and an interior portion that is housed within the rotor channel. By flexing the external portions, a compression force that secures the laminations and the end members with respect to one another may be provided. Advantageously, the external portions may be fused to one another and/or to the end members. As one example, the external portions may be fused through the introduction of a molten metal into the end member. Advantageously, fusing of the external portions to the end members and/or one another increases the mechanical integrity of the rotor and provides for good electrical communicativeness between the conductive members, for example.

    摘要： A laser communication system for full duplex wideband data transmission includes first and second terminals having dichroic wavelength-multiplexed optical systems wherein transmitted and received light are multiplexed along a path through the same aperture. The optical systems each preferably comprise a cassegrain receiver having primary and secondary mirrors for directing both transmitted and received laser light. Modulated laser light is generated by a high-power laser diode which is actively cooled by a thermoelectric cooler. A window in the housing, through which the modulated laser light travels, includes a transparent resistive coating to which electrical current is applied to control the temperature of the window. The aspheric primary mirror has a highly reflective surface, preferably a single-point diamond-turned mirror surface, formed on an aluminum substrate as a single piece.

    摘要： A piston for an internal combustion engine, the engine having a connecting rod coupled to a wristpin, the wristpin being connected to the piston for pivotal movement about an axis, the piston comprising: a top portion and a generally cylindrically-shaped wall portion extending from the top portion, the top and wall portions defining a skirt cavity, the top portion having thereon a downwardly extending projection with a downwardly facing bearing surface for the wristpin, the bearing surface extending in the direction of the axis and defining a portion of a cylinder centered on the axis, and the projection having opposite sides facing the skirt cavity; at least one lubricant passage extending through the projection from one of the opposite sides and over the bearing surface to the other of the opposite sides; and a lubricant opening communicating between the lubricant passage and the bearing surface to supply lubricant to the bearing surface and to the wristpin.
