Patent number: 6280156Abstract: A magnetically coupled rotary pump has, in a pump chamber, a pump rotor mounted by a single slide bearing on a stationary axis of a pump bearing support. The slide bearing is formed on one side by a metal sleeve shrunk over the bearing sleeve, said sleeve being connected by means of a weld with the pump rotor, and on the other side by a bushing mounted on the pump bearing support or a one-piece slide bearing surface formed correspondingly directly on pump bearing support. With this design of the bearing, dead spaces and gaps are avoided, enabling complete cleaning and sterilization of the pump chamber with complete draining of the pump chamber. A pump of this kind is especially suitable for use in sterile applications.Type: GrantFiled: August 23, 1999Date of Patent: August 28, 2001Assignee: CP Pumpen AGInventors: Peter Wirz, Thomas Folsche

Patent number: 5149055Abstract: A piston type of shut-off valve with a sealing ring made of expanded graphite. A plurality of ring-shaped lamellae are each stamped from a foil of expanded graphite and then joined to form a sealing ring. A peripheral edge surface of the sealing ring, rather than its planar facing surface, comes into sealing contact with the piston thereby improving its service life. Service life of the sealing ring can be further improved by using a guard ring on a facing surface of the sealing ring as well as by using an installed density for the sealing ring of 1.5 to 2.2 g/cm.sup.3.Type: GrantFiled: July 6, 1990Date of Patent: September 22, 1992Assignee: Klinger AGInventors: Richard Huber, Peter Wirz

Patent number: 4988422Abstract: Apparatus for reactive sputtering of an electrically resistive coating onto a planar substrate includes a magnetron cathode with a planar target of a metal which forms one component of the coating. The reaction gas, which provides another component of the coating, is released as close as possible to the target, but outside of its outline. The distance "a" between the target surface and the substrate surface is less than 60 mm, and a mask system is provided at a distance "d" from the substrate which is less than half the distance "a". The density of reaction gas particles in front of the substrate is thus increased, resulting in a high deposition rate.Type: GrantFiled: June 8, 1987Date of Patent: January 29, 1991Assignee: Leybold AktiengesellschaftInventor: Peter Wirz

Patent number: 4927513Abstract: A method and apparatus for fabricating magneto-optical, storable, and/or deletable data carriers. One or more layers, each comprising two or more different chemical materials, are applied on a substrate (4) by means of a magnetron sputtering system (1). The fractional composition of each layer is controlled by changing the strength of the magnetic field produced by the magnetron system (1). By means of a suitable measuring device (51, 58) the compensation temperature of a particular layer is measured and compared with a desired value. If the measured compensation temperature differs from the desired value, the desired value can be attained by adjusting the cathode voltage U.sub.K of the magnetron system. A controller (63) is provided for controlling the cathode voltage and adjusting the distance between the magnetron system's target (6) and magnets (8, 9, 10).Type: GrantFiled: January 6, 1989Date of Patent: May 22, 1990Assignee: Leybold AktiengesellschaftInventors: Eberhard Schultheiss, Peter Wirz

Patent number: 4921724Abstract: In an apparatus for coating a substrate with an organic substance by placing the substrate in a coating chamber containing a gaseous hydrocarbon compound, in which the hydrocarbon compound can be broken down by means of a cathode system having magnets, a plasma is formed in the vicinity of the substrate by applying a radiofrequency voltage to the cathode system while the substrate is held immediately in front of the cathode. The pressure in the coating chamber and the supply of the electric energy from the generator to the cathode are variable for the purpose of achieving a coating quality that will change during the build-up of the coating. For this purpose, electric motor-powered valve means are inserted into the gas supply line and into the pump suction line and are operated through a timing mechanism or a control apparatus which is connected to a vacuum gauge.Type: GrantFiled: November 12, 1987Date of Patent: May 1, 1990Assignee: Leybold-AktiengesellschaftInventors: Peter Hubert, Barbara Kussel, Peter Wirz

Patent number: 4895631Abstract: A reaction gas is admitted in the immediate vicinity of a target on the cathode and a plasma is generated between the target and a substrate to be coated. The intensity of the spectral line of a target material is measured, and is used to provide a first signal with a relatively short time constant to a controller via a first control circuit. A property of the finished coating is sensed after the substrate leaves the coating zone, and is used to provide a second signal with a relatively long time constant to the controller via a second control circuit. The controller uses the combined signals to regulate the admission of the reaction gas so that a pre-established property of the finished coating is kept substantially constant.Type: GrantFiled: March 20, 1989Date of Patent: January 23, 1990Assignee: Leybold AktiengesellschaftInventors: Peter Wirz, Friedrich-Werner Thomas

Patent number: 4869802Abstract: In an apparatus for the production of coatings with a uniform thickness profile on substrates by cathode sputtering, a substrate carriage held and guided between rollers is provided, which can be driven through the coating chamber, and which has substrate disks rotatably mounted on its side facing the cathode. The axes of rotation of the substrate disks are disposed transversely of the plane of movement of the substrate carriage. On the side of the substrate carriage facing away from the cathode, a row of permanent magnets is fixedly disposed on magnet holders. The permanent magnets produce a disk current in magnetic disks which are joined for co-rotation with the pivot shafts of the substrate disks. On account of the disk current, the magnetic disks, and with them also the substrate disks, are made to rotate in passing along the row of magnets.Type: GrantFiled: April 5, 1988Date of Patent: September 26, 1989Assignee: Leybold AktiengesellschaftInventors: Peter Wirz, Heinz-Wilhelm Pfannekuche, Thomas Bathon, Karl Eckert

Patent number: 4824545Abstract: An apparatus for coating substrates in a vacuum chamber has a cathode system, which is preceded and followed by evacuable isolating chambers. The individual chambers can be separated from one another by locks, and the apparatus has a conduit leading into the coating chamber for feeding one or more process gases. Transport frames carry the substrates through the individual chambers on rails and/or wheels. In such an apparatus one or more bypass lines are provided which connect the coating chamber to the isolating chambers preceding or following it, and a shutoff or valve is inserted into each bypass line and brings about an equalization of pressure between the chambers. By means of a pressure equalization performed in this manner, the constancy of the gas concentrations which is essential in a reactive process to the stability of the process and to uniform coating properties, is automatically assured.Type: GrantFiled: December 17, 1987Date of Patent: April 25, 1989Assignee: Leybold AktiengesellschaftInventors: Manfred Arnold, Peter Wirz
