Publication number: 20120046782Abstract: In a method for producing at least one surface on a workpiece by a material removal tool and a corresponding material removal device, the surface is produced quickly and at low cost. Based on any surface to be produced, a movement path of the material removal tool is controlled to produce a ruled surface approximating to the surface, the movement path being provided in the form of a curve on a dual unit sphere, wherein a curve point corresponds to a location and an orientation of the removal tool. The curve can be produced based on ruling lines, which are converted into points, interpolated by a dual sphere spline interpolation algorithm, on the dual unit sphere by mathematical transformations. The curve can then be transformed back or can be used directly to follow the material removal tool. Likewise, directrix curves can be determined by the dual sphere spline interpolation algorithm.Type: ApplicationFiled: April 19, 2010Publication date: February 23, 2012Inventors: Jörg Schulze, Yayun Zhou

Patent number: 7101812Abstract: A process for forming and/or modifying dielectric films on semiconductor substrates is disclosed. According to the present invention, a semiconductor wafer is exposed to a process gas containing a reactive component. The temperature to which the semiconductor wafer is heated and the partial pressure of the reactive component are selected so that, sometime during the process, diffusion of the reactive components occurs through the dielectric film to the film/semiconductor substrate interface. Further, diffusion also occurs of semiconductor atoms through the dielectric film to an exterior surface of the film. The process of the present invention has been found well suited to forming and/or modifying very thin dielectric films, such as films having a thickness of less than 8 nm.Type: GrantFiled: March 10, 2003Date of Patent: September 5, 2006Assignee: Mattson Technology, Inc.Inventors: Ignaz Eisele, Alexandra Ludsteck, Jörg Schulze, Zsolt Nenyei, Waltraud Dietl, Georg Roters

Publication number: 20060179980Abstract: A method of coupling a tool to a length of tubular comprises securing the tool in a basket; lowering a tong arrangement having a rotary part and a stationary part, relative to the basket to engage respective locking members of the tong arrangement and the basket, thereby fixing the basket and the tool relative to the stationary part of the tong arrangement; and rotating the length of tubular using the rotary part of the tong arrangement so as to couple the tool to the length of tubular. A torque measuring flange may be associated with the tong arrangement. The torque measuring flange comprises a top plate and a bottom plate and one or more cylinders disposed between one or more wedges, whereby rotating the top plate causes the wedges to compress a piston in the cylinder.Type: ApplicationFiled: April 11, 2006Publication date: August 17, 2006Inventors: Bernd-Georg Pietras, Andreas Carlsson, Jorg Schulze-Beckinhausen

Patent number: 6528433Abstract: The novel method allows monitoring of nitrogen processes by making use of the fact that the incorporation of nitrogen near the surface in silicon, or in a thin silicon nitride layer on the silicon surface, inhibits the diffusion of oxygen during the subsequent thermal oxidation. Accordingly, the oxidation rate of the thermal oxidation is reduced and the growth of the oxide layer on the silicon surface is inhibited. The thickness of the oxide layer is thus used as a measure for the nitrogen content, i.e., for the quality of the nitrogen process.Type: GrantFiled: June 14, 2001Date of Patent: March 4, 2003Assignee: Infineon Technologies AGInventors: Thomas Gärtner, Alexandra Lamprecht, Dietmar Ottenwälder, Jörg Schulze

Patent number: 6082224Abstract: A new power tong for rotating tubular members for make-up (connection) and break-out (disconnection) operations. In one aspect such a tong has at least one movable jaw with a smooth surface gripping element thereon and pre-load apparatus for applying a pre-load force to a movable jaw so that the jaw does not slip on a tubular to be rotated and so it does not mark or damage the tubular. In one aspect the pre-load apparatus includes a first pre-load device at one end of a movable jaw for breakout operations and a second pre-load device at another end of the jaw for make-up operations. In one aspect a power tong which has unique smooth surfaced jaw inserts made, e.g., of aluminum. In one aspect a single pivotable pre-load cylinder, fixed to rotary, pivots for pivotable connection to one jaw or the other. This can be done manually or a powered smaller piston/cylinder may be used to pivot the pre-load cylinder.Type: GrantFiled: February 19, 1997Date of Patent: July 4, 2000Assignee: Weatherford/Lamb, Inc.Inventors: Gary McDaniels, Patrick Cummings, Michael Hayes, Steven Albright, Bernd G.

Patent number: 4776243Abstract: A power tong assembly wherein a safety latch mechanism includes a power part equipped with two outlet side connections, one of which is connected to a control part for controlling the opening cross section of the tank side connection. The power part has a control element in the form of a piston-shaped valve body with equal sized surfaces on both end faces subject to the pressure of the working medium and with a bore running in the direction of the valve body movement. This bore has a conical extension of its inlet flow end. This blocks the direct connection of the supply with the return to the tank.Type: GrantFiled: November 26, 1985Date of Patent: October 11, 1988Assignee: Weatherford/Lamb, Inc.Inventors: Jorg Schulze-Beckinghausen, Hans-Christian Bock

Patent number: 4192206Abstract: An apparatus for rotating a tubular member. The apparatus has a housing with a recess for receiving the tubular member; a latch for closing off the recess; an operating means for the latch; a gear rim; discs within the housing to guide and retain the gear rim; a power means for driving the gear rim; and a crescent-shaped carrier member within the gear rim having means for contacting and gripping the tubular member. Either forward or reverse rotation of the gear rim results in the gripping of the tubular member and the imparting of torsion to the tubular member.Type: GrantFiled: June 6, 1978Date of Patent: March 11, 1980Assignee: Weatherford Lamb, Inc.Inventor: Jorg Schulze-Beckinghausen
