Patent number: 7169479Abstract: The invention relates to a grain-oriented magnetic steel sheet including an electrically insulating coating made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of the sheet. The grain-oriented magnetic steel sheet including the electrically insulating coating made of an amorphous carbon-hydrogen network can be used in transformers.Type: GrantFiled: June 21, 2002Date of Patent: January 30, 2007Assignee: ThyssenKrupp Electrical Steel EBG GmbHInventors: Bernd Schuhmacher, Klaus Guenther, Hermann Hingmann, Klaus Bewilogua, Claus-Peter Klages, Heinz Dimigen, Thomas Jung

Publication number: 20050112377Abstract: The invention relates to grain-oriented magnetic steel sheet comprising an electrically insulating coating, made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of sheet, said grain-oriented magnetic steel sheet being used e.g. in transformers. The invention also relates to a method for producing the grain-oriented magnetic steel sheet comprising an electrically insulating coating made of an amorphous carbon-hydrogen network, which method consists of coating of the strip-shaped sheet substrate taking place in a continuous strip method. The application is to be published without a Figure.Type: ApplicationFiled: June 21, 2002Publication date: May 26, 2005Inventors: Bernd Schuhmacher, Klaus Guenther, Hermann Hingmann, Klaus Bewilogua, Claus-Peter Klages, Heinz Dimigen, Thomas Jung

Patent number: 5170563Abstract: A shaving unit for a shaver is provided comprising a shear plate and a cutting member, one of the cooperating surfaces being covered with a friction-reducing layer comprising carbon and metal in an atomic ratio between 50.1/49.9 and 99.9/0.1.Type: GrantFiled: January 23, 1989Date of Patent: December 15, 1992Assignee: U.S. Philips Corp.Inventors: Adriaan Van der Grijn, Hendrik W. Strijker, Heinz Dimigen, Hubertus Hubsch

Patent number: 4828728Abstract: Layers of carbon with a thickness ranging from 10 nm to 10 .mu.m with a diamond-like crystalline structure in a vacuum under a protective atmosphere, but also in atmospheric conditions, represent an excellent dry lubricant which is characterized by a very low coefficient of sliding friction (.mu..congruent.0.01 to 0.1) and also by a very high abrasion resistance.The adhesion of the carbon layer to bearing surfaces can be improved by an intermediate layer between the lubricating layer and the bearing surface. The intermediate layer preferably has a lattice structure similar to that of the lubricating layer.Type: GrantFiled: March 27, 1984Date of Patent: May 9, 1989Assignee: U.S. Philips CorporationInventors: Heinz Dimigen, Hubertus Hubsch

Patent number: 4525417Abstract: A workpiece comprises a substrate having a sliding surface provided with a friction-reducing coating. Such coating consists essentially of elemental carbon dispersed in a matrix formed of at least one metallic element in the proportions of 50.1 to 99.1 at % of the elemental carbon and 0.1 to 49.9 at % of the metallic element. The ratio of the metallic element to the elemental carbon differs from the stoichiometric ratio of the carbide.Type: GrantFiled: February 24, 1983Date of Patent: June 25, 1985Assignee: U.S. Philips CorporationInventors: Heinz Dimigen, Hubertus Hubsch

Patent number: 4264027Abstract: The driving arrangement for a magnetic tape is comprised of a drive shaft having a smooth surface and a pressure roller having a high surface friction coefficient. The circumference of the drive shaft is provided with a thin layer of the borides, nitrides or carbides of a hard metal, which increases the friction resistance of the shaft. This measure reduces the slip, without affecting the proper uniform travel of the tape.Type: GrantFiled: October 31, 1979Date of Patent: April 28, 1981Assignee: U.S. Philips CorporationInventors: Horst Althuber, Heinz Dimigen, Hubertus Hubsch

Patent number: 4119483Abstract: A method of structuring oxide layers, nitride layers or magnetic layers in such manner that a photolacquer mask is manufactured on a substrate and the layer to be structured is provided by means of cathode sputtering both on the photolacquer mask and on the surfaces of the substrate not covered with lacquer. The substrate is then treated with a solvent attacking the lacquer mask; the mask swells up and the parts of the layer to be structured present thereon are chipped off. In order to stimulate this latter process, a layer is provided below the photolacquer mask on the substrate relative to which photolacquer has a small adhesive capacity and, after providing the layer to be structured, an increase in volume of the lacquer mask is produced by thermal treatment. After the complete removal of the photolacquer mask and the parts of the layer to be structured present thereon, the structured thin layer remains on the substrate as a negative of the pattern of the photolacquer mask.Type: GrantFiled: February 8, 1977Date of Patent: October 10, 1978Assignee: U.S. Philips CorporationInventors: Hubertus Hubsch, Ursula Convertini, Heinz Dimigen, Holger Luthje

Patent number: 4049521Abstract: In usual practice, cathodically etched structures typically show either non-etched parts (strong readsorption of sputtered material) or the etched structure shows strong grooves at the edges of the etching mask (strong back-diffusion of sputtered material). With a variation of the working gas pressure an adjustability of the average free path length of the atoms of the sputtered material and hence the adjustability of the quantity of material redeposited on the basis of back-diffusion is obtained. The working gas pressure can hence be adjusted so that the etching time to remove the readsorbed material and the material deposited again by back-diffusion is locally constant and equal etching rates are obtained for all areas of the structure to be etched.Type: GrantFiled: June 7, 1976Date of Patent: September 20, 1977Assignee: U.S. Philips CorporationInventors: Ursula Convertini, Heinz Dimigen, Holger Luthje
