    摘要: A method for curing a resinous composition comprising an admixture of a thermosetting resin and dielectrically lossy particles is described wherein the lossy particles have a dielectric constant substantially the same as the dielectric constant of the resin. The method comprises subjecting said admixture to a high frequency alternating electric field for sufficient time to heat the lossy particles and initiate the chemical reaction to cure the resin. Also described are shaped articles of manufacture made by curing resinous compositions in accord with the described method. Such articles have enhanced mechanical properties due to the curing process.

    摘要: A chemical mechanical polishing system having a wafer carrier assembly is provided. The wafer carrier assembly includes a wafer carrier support frame, a wafer carrier head housing rotable mounted on the wafer carrier support frame, with a base including a bladder bellows operating connecting the wafer carrier base to the wafer carrier head housing such that rotational torque is transferred from the wafer carrier head housing to the wafer carrier base. Further provided is a retaining ring, operatively connected to a retaining ring bearing which allows relative axial motion while constraining relative radial motion between the retaining ring and the wafer carrier head housing; and a retaining ring bellows, operatively connecting the retaining ring bearing to urge the retaining ring against a polishing member. A chamber formed by the bladder bellows, the wafer carrier base and the wafer carrier head housing may be pressurized to load the wafer carrier base against a polishing member, independent of any frictional loads on the retaining ring.

    摘要: Disclosed herein is an improvement in microcellular or supermicrocellular polymer extrusion systems. Both conventional and microcellular systems employ an extruder which plasticates polymer pellets into a polymer melt; a gas metering system, whereby a gas is injected directly in the polymer melt flow in the extruder; a mixing and homogenizing section of the extruder, which creates a single-phase solution of the polymer and the gas; and a nucleation device at the outlet end of the extruder. In this invention, the improvement to the conventional system comprises the nucleation means attached to said extruder which is a gear pump acting as a throttle rather than a pump. With this improvement, the discharge pressure is dictated by die resistance and flow rate as delivered by the gear throttle, and the pressure drop of the polymer/gas single-phase solution is nearly instantaneous.

    摘要: A method for determining the moisture content of dielectric materials is described wherein a sample of the material is placed between two electrodes and an electric field is applied. An alternating frequency in the range of radio waves and lower is applied to the electrodes and the dielectric loss properties of the material are determined. The dielectric loss properties are then used to determine moisture content. In an alternate embodiment, a step voltage is applied to the electrodes and the direct current is monitored. The decrease in value of direct current during a time interval following the application of the step voltage is used to determine the moisture content.

    摘要: A method and apparatus for forming a mixture of solid particles of two different types wherein the particles of one type are electrically charged with a charge of one polarity, e.g., a positive polarity, and the particles of the other type are electrically charged with a charge of the opposite polarity,e.g., a negative polarity. The charged particles are combined over a selected time period during which they retain their mobility so that at the end of such time period they form a mixture the characteristic of which is better than a random mixture, i.e., the ratio of the number of particles of one type to the number of particles of the other type in each of a plurality of samples thereof tends to be the same as the ratio of the number of particles of said one type to the number of particles of the other type in the overall mixture.
