Abstract: The present invention provides a rotating shaft that can extend between two regions having different ambient pressures. The rotating shaft can include a rotatable hollow outer shell that is coupled to a proximal portion of an inner shaft with a limited number of contact points. A plurality of thermal breaks disposed between the inner shaft and the hollow outer shell impede heat transfer between these two components. A rotary seal coupled to the distal portion of the inner shaft preserves the pressure differential between the two regions. Further, a heat sink removes heat transferred to the seal to ensure that the temperature of the seal remains within a range suitable for its operation. The rotating shaft of the invention can be utilized, for example, in an ion implantation system by the coupling of the outer shell to a wafer holder to position and orient a wafer in a path of an ion beam.

Abstract: This invention concerns nanoscale products, such as electronic devices fabricated to nanometer accuracy. It also concerns atomic scale products. These products may have an array of electrically active dopant atoms in a silicon surface, or an encapsulated layer of electrically active donor atoms. In a further aspect the invention concerns a method of fabricating such products. The methods include forming a preselected array of donor atoms incorporated into silicon. Encapsulation by growing silicon over a doped surface, after desorbing the passivating hydrogen. Also, using an STM to view donor atoms on the silicon surface during fabrication of a nanoscale device, and measuring the electrical activity of the donor atoms during fabrication of a nanoscale device. Such products and processes are useful in the fabrication of a quantum computer, but could have many other uses.

Abstract: The present invention provides a beam stop for use in an ion implantation system that includes a base formed of a thermally conductive material, and a heat transfer layer formed of a semi-elastic material that is disposed on a surface of the base. The beam stop further includes one or more tiles, each formed of a thermally conductive refractory material, that are disposed on the semi-elastic layer so as to face an ion beam in the implantation system. The heat transfer layer transfers heat generated in the tile in response to ion beam impact to the base. The base in turn can be coupled to a heat sink to remove heat from the base. The thickness and the thermal conductivity of the base, and those of the heat transfer layer and the tile are chosen so as to ensure uniform expansion of the base and the tile when the beam stop is heated by ion beam impact.

Abstract: Wafer-holding structures formed from thermosetting resins are disclosed for use in semiconductor processing including, for example, SIMOX wafer processing. In one embodiment a pin is disclosed that is adapted to receive a wafer edge, and is coupled with a wafer holder assembly. The pin can be filled with a conductive material to provide an electrical pathway between the wafer and the wafer holder assembly, which can be coupled to a ground. This arrangement provides a conductive path for inhibiting electrical discharges from the wafer during the ion implantation process. The pin exhibits thermal isolation characteristics and sufficient hardness so as to not effect localized thermal dissipation of the wafer, yet is sufficiently soft so as to not mark or otherwise damage the wafer.

Abstract: An ice ball launcher simulates the impact of a storm-generated hailstone falling onto a test specimen or structural component exhibit such as a roofing shingle, skylight, automobile panel, aircraft fuselage panel, aircraft wing panel and the like. The launcher includes a tripod base, a rail, a sled, an ice ball holder cup, a manually operable trigger latch assembly, an elastic band and a laser beam aiming device. The ice ball launcher consistently and repeatably projects ice balls at a predetermined velocity and impact energy onto the component sample. The velocity of each ice ball is measured as it transits from the ice ball launcher to the installation mockup, verifying that the ice ball velocity is within a predetermined velocity tolerance range. The measured velocity and known mass of the ice ball are used to calculate the kinetic impact energy on the component sample material, and to determine whether the calculated impact energy is within a predetermined impact energy tolerance range.

Abstract: Phase shifting network (110) predistorts the input to non-linear amplifier (114) to counteract AM-PM distortion. The input signal is sampled at (116) and its amplitude is detected at (118). The amplitude signal is then used to index a lookup table (122) which contains corresponding data for controlling the phase shifting network (110). The input signal may be digital and the phase shifting process may be implemented in the digital domain.

Abstract: A method and system are described that can be used to support a process interaction among a group of participants connected to a network. A participant completes an electronic form specifying the subject matter of the process interaction and a list of network addresses corresponding to other participants in the interaction. A server receives the form and includes resources for delivering an electronic mail message associated with an electronic medium associated with the interaction. When the participant opens the message, the electronic medium is produced by the server that includes static and dynamic regions. The participant can add comments to the interaction or direct the process interaction using an interaction region. The dynamic regions are asynchronously updated in the server and indicate the current content of the electronic medium that can be accessed by other participants.

Abstract: Method, control system and computer-readable medium are respectively provided for determining angular crankshaft position prior to a cranking event of an internal combustion engine. Upon issuance of an engine shutdown command, the method allows determining an initial crankshaft position based on a crankshaft position sensor. The method further allows providing a rulebase for relating angular travel of a rotor in an accessory device to crankshaft angular travel.

The rulebase is accessed to relate the value of the angular travel of the rotor in the accessory device to crankshaft angular travel and provide an incremental crankshaft angular travel relative to the initial crankshaft position at engine shutdown.
