Publication number: 20110151675Abstract: A spin chuck in an apparatus for single wafer wet processing has structures at its periphery that, in combination with a supported wafer, form a series of annular nozzles that direct flowing gas from a chuck-facing surface of the wafer, around the edge of the wafer, and exhaust the gas away from the non-chuck-facing surface of the wafer, thereby preventing treatment fluid applied to the non-chuck-facing surface from contacting the edge region of the wafer. Retaining pins with enlarged heads engage the wafer edge and prevent it from being displaced upwardly when a high flow rate of gas is utilized.Type: ApplicationFiled: December 18, 2009Publication date: June 23, 2011Applicant: LAM RESEARCH AGInventors: Dieter FRANK, Michael PUGGL

Patent number: 7905557Abstract: A valve control unit including three valve units for two brake channels of an electropneumatic brake system is provided. Each valve unit is embodied as a valve modulator device for a braking pressure control circuit including an air inlet valve with a primary solenoid and a bleed valve with a secondary solenoid. Each modulator device armature includes a common solenoid guide arrangement controlled by the magnetic flux of a common magnetic coil. Independent operation of the armatures is achieved whereby flux through the secondary solenoid is weakened by a shunt in the flux circuit which causes a switching delay for the secondary solenoid relative to the primary solenoid. The magnetic resistance of a non-magnetic disc effects switch-off acceleration in the flux circuit with energized secondary solenoid, weakens the field and causes the secondary solenoid to revert to a spring-loaded base state at a higher flux than the primary solenoid.Type: GrantFiled: July 5, 2005Date of Patent: March 15, 2011Assignee: WABCO GmbHInventors: Dieter Frank, Juan Rovira-Rifaterra, Armin Sieker, Andreas Teichmann

Patent number: 7369023Abstract: A method for manufacturing magnet armatures which are used mainly in brake-pressure modulators of electronically controlled brake systems and which are provided on their entire surface with a plastic coating, for reasons of dimensional stability and sliding properties. Magnet armatures of this type are constructed as cylindrical members and are usually provided in the region of one of the two end faces with an elastomeric sealing element, which according to the prior art is bonded to the magnet armature by vulcanization, an adhesive elastomer-to-metal bond being formed between the magnet armature and the elastomeric sealing element during vulcanization. Since bonds of this type are not possible for a completely coated magnet armature, the elastomer for the elastomeric sealing element is, according to the invention, vulcanized onto the armature without using an adhesion promoter.Type: GrantFiled: March 18, 2002Date of Patent: May 6, 2008Assignee: WABCO GmbH & Co., OHGInventors: Dieter Frank, Siegfried Höfler, Armin Sieker

Patent number: 6662825Abstract: A control device for pressurized fluids includes a valve mechanism actuated by a first device incorporating electromagnets in a first housing, and a second device incorporating a circuit board for controlling the valve mechanism in a second housing. Pins on the first device and sockets on the second device automatically form an electrical plug-type connection when the housings are joined. Each socket is received in a first portion of a through-hole provided in a mount supported on the circuit board such that it extends into a corresponding through-hole in the circuit board. A second portion of each through-hole in each mount has a funnel-shaped guide opening toward the pins. A pressure sensor supported by the circuit board forms a plug-type engagement with a port extending from the valve mechanism when the housings are joined. Contacts extend from the sensor into holes in the circuit board.Type: GrantFiled: February 11, 2002Date of Patent: December 16, 2003Assignee: Wabco GmbH & Co.

Patent number: 6626505Abstract: A pre-engagement unit for a braking pressure modulator for a pressure regulating circuit includes a first pneumatic inlet, a second pneumatic inlet, a first pneumatic output terminal, and a second pneumatic output terminal. The unit includes an electrically actuated valve system having a plurality of solenoid valves and a plurality of electrical terminals connected to output terminals of an electronic control unit. An electric braking command signal transmitter delivers a driver initiated electric brake value setting to an input of the electronic control unit. Under normal conditions, a supply pressure and a redundancy pressure are delivered at the first pneumatic output terminal to be converted by an air quantity augmenting relay valve to a braking pressure. In case of failure of the electronic braking system, the redundancy pressure is delivered at the first pneumatic output terminal to be converted by the air quantity augmenting relay valve to the braking pressure.Type: GrantFiled: February 23, 2001Date of Patent: September 30, 2003Assignee: WABCO GmbH & Co.

Patent number: 6467854Abstract: A pre-engagement unit for a braking pressure modulator for a pressure regulating circuit of an electronic braking system includes an electrically actuated valve system with three substantially identical 2/2-way solenoid valves. First and second terminals of the 2/2-way solenoid valves are selectively connected to the pneumatic inlets and output terminals of the pre-engagement unit, and to each other so that the first 2/2-way valve serves as an air admission valve for supply pressure, the second 2/2-way solenoid valve serves as an air admission/exhaust valve for redundancy pressure, and the third 2/2-way solenoid valve serves as an exhaust valve. Thereby, the pressure in the pressure regulating circuit can be increased, decreased, or maintained. Desirably, the first, second, and third 2/2-way solenoid valves are connected in parallel to each other.Type: GrantFiled: February 23, 2001Date of Patent: October 22, 2002Assignee: WABCO GmbH & Co., OHGInventors: Dieter Frank, Gerdt Schreibert, Peter Homann, Armin Sieker, Andreas Kranz, Hans-Klaus Wolff, Dirk Meier
