Patent number: 8696811Abstract: A feed assembly and method of use thereof of the present invention is used for the addition of a high pressure dopant such as arsenic into a silicon melt for CZ growth of semiconductor silicon crystals. The feed assembly includes a vessel-and-valve assembly for holding dopant, and a feed tube assembly, attached to the vessel-and-valve assembly for delivering dopant to a silicon melt. An actuator is connected to the feed tube assembly and a receiving tube for advancing and retracting the feed tube assembly to and from the surface of the silicon melt. A brake assembly is attached to the actuator and the receiving tube for restricting movement of the feed tube assembly and locking the feed tube assembly at a selected position.Type: GrantFiled: November 25, 2009Date of Patent: April 15, 2014Assignee: MEMC Electronic Materials, Inc.Inventors: Massoud Javidi, Steve Garner

Publication number: 20050031382Abstract: A developer sleeve for use in a monocomponent development system has a surface coating formed by an electric arc spray method. In one embodiment compressed air at a pressure of greater than 100 psi is used for driving the metal spray from the arc to the tube to be coated. In another embodiment, the developer sleeve is fabricated using mounting components of heat capacity and thermal conductivity both higher than that of the sleeve. In a still further embodiment, compressed air at a pressure of up to 100 psi is guided into the workpiece in order to dissipate heat from the interior of the workpiece. In a yet further embodiment, compressed air is used to aid disassembly of the sleeve from a mounting system following formation of the surface coating.Type: ApplicationFiled: April 23, 2004Publication date: February 10, 2005Applicant: GCC Management LimitedInventors: Raphael McCarthy, Ariel Navela, An Sheng Jiang, Steve Garner, Benjamin Grundy

Patent number: 5507830Abstract: A modular hip prosthesis can be custom fitted to a particular patient by a surgeon prior to surgical insertion. The prosthesis features a body having a neck portion for carrying a rounded head element, a transitional mid-section of the prosthesis body includes generally rectangular and generally rounded cross-sectional areas, and a stem section has a generally rounded cross-sectional area. The stem is tapered to receive a tubular extension sleeve with a hollowed portion corresponding in shape to the stem portion of the prosthesis. The tubular extension sleeve has an open end portion receptive of the lower tapering stem of the prosthesis body. The stem portion includes an internal bore, and an attachment in the form of an elongated screw is provided for connection to the stem internal bore for securing the extension sleeve and the prosthesis body together, forming a compressive sealed connection therebetween.Type: GrantFiled: September 28, 1993Date of Patent: April 16, 1996Assignee: Smith & Nephew Richards Inc.Inventors: Michael DeMane, Thomas W. Fallin, Steve Garner, Jeff Schryver, Robert Brosnahan

Patent number: 4718908Abstract: A surgical implant manufactured from austenitic stainless steel by cold-forging has improved mechanical properties and corrosion fatigue resistance. The grain-size index for the cold-forged 316L stainless steel is increased from an ASTM grain-size index of about 8 to an ASTM grain-size index of about 14 by cold-forging the steel into the desired shape. Further improvement in mechanical properties and corrosion fatigue resistance is obtained by stress relieving the material after cold-forging into the desired configuration. The microstructure of the cold-forged material is characterized by the absence of visible slip planes at 600.times. magnification, in contrast with visible slip planes present in the microstructure of the austenitic stainless steel starting material.Type: GrantFiled: June 4, 1984Date of Patent: January 12, 1988Assignee: Richards Medical CompanyInventors: Robert E.

Patent number: 4109236Abstract: A digital data recovery apparatus for extracting phase encoded data from mass storage devices is disclosed. By selective strobing of the data string at a frequency determined by the incoming data rate of data already read, a continuously updated data "window" is generated. The data synchronization, clock control and frequency averaging of the previously read data is accomplished without the use of any analog circuitry.Type: GrantFiled: June 17, 1977Date of Patent: August 22, 1978Assignee: Honeywell Information Systems Inc.Inventors: Edward Roald Besenfelder, Steve Garner Cantrell, Charles Peter Cobeen

Patent number: 4053738Abstract: A programmable data envelope detector indicates the presence of phase encoded data being transmitted to or received from a data storage medium. The detector generates an output signal at a predetermined time after detecting the presence of data and continues to provide such output signal for a predetermined time after detecting the end of data. The detector comprises a data pulse detector, three-count up-down counter, two multicount four-bit up-down counters, a microprogrammable control store and decoder, a compare circuit, and a latch circuit. The time periods at which the latch circuit generates the output signal are different depending upon the nature of the data transfer operation, such time periods corresponding to different microinstructions in the control store.Type: GrantFiled: September 27, 1976Date of Patent: October 11, 1977Assignee: Honeywell Information Systems Inc.Inventors: Edward Roald Besenfelder, Steve Garner Cantrell
