摘要： A subfractional horsepower, permanent magnet motor has a stator assembly with a pair of axially aligned stator coils in stacked relation, and complementary metal housing members that enclose the coils and define a series of stator poles. An elongated sleeve disposed within the annular stator assembly provides, with the metal housing members, magnetic circuits that surround the stator coils. The stator sleeve is disposed over and interfitted with a frame core that has significantly greater thermal conductivity than the thermal conductivity of the stator sleeve. A channel extends from at least one of the stator coils along the axial length of the core to the base, and the leads of that coil extend radially inward from the coil and along the channel to the base and therefrom externally of the motor. The motor rotor has a cylindrical sleeve portion with a circumferential array of axially extending permanently magnetized rotor poles equally spaced about the periphery, and the rotor is supported such that a uniform annular air gap is provided between the outer surface of the stator assembly and the inner surface of the rotor sleeve.

摘要： A method and system for three-dimensional imaging of objects, including integrated circuit interconnections to improve the efficiency of triangulation-based laser line scanning systems. A scanning beam is incident at a normal angle to the X,Y inspection plane with the scan line oriented at 45 DEG , diagonal to an axis defining a first direction of motion. Motion of the imaging head along the axis is used to acquire line scan images in the non-orthogonal coordinate system.

摘要： A method and system are provided for flipping a tray of parts such as integrated circuit packages including a pair of flippable storage trays. A first storage tray has an upper surface which forms a grid of storage compartments wherein each of the storage compartments is adapted to hold a single integrated circuit package. Initially, the first tray is received at a flip station from a first part processing station. Then, the first and second trays are joined together so that they mate. Then, the mated first and second trays are inverted so that the packages are held in the second tray. Then, the first and second trays are separated and the second tray which now holds the plurality of packages is transferred to a second part processing station. Then, the cycle is repeated with a third tray of parts and the now empty first tray.

摘要： A rotary bearing includes concentric radially spaced-apart inner, intermediate and outer rings whose opposing surfaces define inner and outer ball tracks. An inner array of balls roll along the inner track and an outer array of balls roll along the outer track and a viscous lubricant is present between the rings. When the inner and outer rings are angularly reciprocated relative to one another and that reciprocation is changed, the intermediate ring is moved intermittently in a selected direction about the rotation axis so that the balls recirculate about the axis and redistribute lubricant along the tracks.

摘要： A shaft angle transducer uses a rectangular prism to refract a light beam in proportion to the angular displacement of a shaft and then measures the refraction with a pair of light sensors. A fixed light source projects a light beam through a cylindrical lens and the prism to produce a patch of light on the fixed light sensors. An aperture shapes and sizes the light patch to nearly match the dimensions of one of the light sensors. The prism rotates with the shaft and refracts the light beam in proportion to the rotation angle. As the patch translates across the surface of the light sensors, more light impinges on one light sensor and correspondingly less light impinges on the other light sensor. The difference between the signals produced by the two light sensors produces an output signal that approximates the angular displacement of the shaft from a null position. The distance through which the light patch translates depends on the angular displacement of the prism and is immune to radial or axial translation of the prism.

摘要： A pulsed laser system includes a laser pump, a laser rod, a reflector interposed between the laser pump and the laser rod, through which energy from the laser pump enters the laser rod, an output reflector through which energy is emitted from the laser rod, a switch interposed between the laser rod and the output reflector, and a control device. The switch, when closed, causes energy to be stored in the laser rod and, when opened, allows energy to be emitted from the laser rod during an emission period. The control device allows a primary laser pulse emitted from the laser rod during the emission period to impinge on a workpiece and blocks from the workpiece secondary laser emission occurring during the emission period after emission of the primary pulse. The pulsed laser system is operated over a range of repetition rates, so as to cause laser energy to be emitted during a plurality of emission periods at each repetition rate. At least a portion of the laser energy emitted during the emission periods is directed toward the target structure in order to perform passive or functional trimming of the target structure. The switch is closed for a fixed, predetermined period of time prior to each emission period regardless of repetition rate of the primary laser pulse within the range of repetition-rates in order to store energy in the laser rod. The pump is operated continuously at constant power.
