  • Publication number: 20100309604
    Abstract: Wafer temperature is measured as a function of time following removal of a heat source to which the wafer is exposed. During the wafer temperature measurements, a gas is supplied at a substantially constant pressure at an interface between the wafer and a chuck upon which the wafer is supported. A chuck thermal characterization parameter value corresponding to the applied gas pressure is determined from the measured wafer temperature as a function of time. Wafer temperatures are measured for a number of applied gas pressures to generate a set of chuck thermal characterization parameter values as a function of gas pressure. A thermal calibration curve for the chuck is generated from the set of measured chuck thermal characterization parameter values and the corresponding gas pressures. The thermal calibration curve for the chuck can be used to tune the gas pressure to obtain a particular wafer temperature during a fabrication process.

  • Publication number: 20100288151
    Abstract: A method and apparatus for incorporating nanophase elemental materials and metastable interstitial composite materials into projectiles, projectile fragments, ordnance casings, warheads and structural components. The projectile, fragments and casings include an elemental material capable of oxidizing. A coating material that is capable of preventing oxidation of the elemental material and an oxidizing agent may be present and be capable of reacting with the elemental material so that a self-propagating high temperature synthesis reaction from a stabilized solid material is yielded for the purpose of rendering terminal effects or thermal impact to a target at impact.

  • Patent number: 7816074
    Abstract: The present invention is directed to a screening mechanism for identifying members of the general population at increased risk for alcoholism and premenstrual syndrome. The screening mechanisms may be used to measure the expression of the ?4?2? GABAA receptors, in order to identify members of the general population as having an increased sensitivity to lower concentrations alcohol coupled with a decrease sensitivity to higher concentrations of alcohol, a scenario frequently found in patients suffering from alcoholism and premenstrual anxiety. Methods of screening for drugs which decrease expression of the ?4?2? subunit of GABAA are also provided.

  • Patent number: 7755041
    Abstract: A triacetone triperoxide cloud associated with a triacetone triperoxide explosive attached to a hard target is remotely detected by operating differential-absorption lidar lasers to transmit a laser beam toward the hard target at differing wavelengths. A backscattered laser beam reflected from the lidar target (hard target, person, aerosols, clouds, buildings) is detected because a cloud of triacetone triperoxide in front of the lidar target and between the lidar target and the differential-absorption lidar system produces a differential-absorption signal having characteristics that identify the triacetone triperoxide. In a second embodiment, a triacetone triperoxide cloud that is absorbing optical radiation from its ambient environment and which is attached to a hard target is detected from a location remote from the triacetone triperoxide explosive by detecting an optical radiation absorption signature characterized by triacetone triperoxide absorption lines.

  • Publication number: 20100108261
    Abstract: A lower electrode assembly for use in a plasma processing chamber comprises a metal base and upper and lower edge rings. The metal base comprises metal plates brazed together and forming a brazed line on a lower side surface of the base, an edge ring support surface extending horizontally inwardly from the lower side surface and an upper side surface above the edge ring support surface. The upper edge ring comprises a lower surface mounted on the edge ring support surface and the lower edge ring surrounds the lower side surface of the base with a gap between opposed surfaces of the upper and lower edge rings and between the lower edge ring and the outer periphery of the base. The gap has an aspect ratio of total gap length to average gap width sufficient to impede arcing at the location of the braze line.

  • Publication number: 20090200115
    Abstract: The device lubricates a sail edge channel, such as a luff channel in a luff channel extrusion fitted to a forestay of a sloop. The device comprises a slide arranged for insertion into and for sliding along the channel and a reservoir for containing a lubricant. A web connects the slide to the reservoir and extends from the slide out of the sail edge channel so that the slide can slide in the channel with the reservoir outside the sail edge channel. A passageway extends from the reservoir and through the web to at least two outlets from the slide arranged at different angular positions around the slide. The lubricant can be expelled from the reservoir into the passageway so that the lubricant is expelled from the outlets into the sail edge channel.
