Patent number: 6881451Abstract: A process for producing a wear-resistant cylinder bearing surface includes rotating a laser about its longitudinal axis and simultaneously advancing the laser in a direction of the longitudinal axis which is coaxial with a cylinder of a crankcase. A powdery material is fed through the laser and a jet of the powdery material is directed toward the cylinder bearing surface. A laser beam is deflected to an impact region where the jet of the powdery material impinges on the cylinder bearing surface. The jet of the powdery material passes through the laser beam. The laser beam at least partially melts the impact region before the powdery material impinges on the impact region. A device for producing wear-resistant surfaces is also provided.Type: GrantFiled: August 20, 2001Date of Patent: April 19, 2005Assignee: Volkswagen AGInventors: Rolf Heinemann, Klaus Färber, Achim Sach

Patent number: 6855910Abstract: A method of laser marking metals, plastics, ceramic materials, glazes, glass ceramics, and glasses of any desired form, which includes applying to the material to be marked a variable thickness layer of marking material containing energy absorbing enhancers then irradiating said layer with a laser or diode based energy source such that the radiation is directed onto said layer in accordance with the form of the marking to be applied, and using a laser or diode based energy source of a wavelength which is sufficiently absorbed by the marking material so as to create a bonding of the marking material to the surface of the workpiece at the irradiated areas.Type: GrantFiled: November 6, 2001Date of Patent: February 15, 2005Assignee: Thermark, LLCInventor: Paul Wollcott Harrison

Patent number: 6836354Abstract: A method for producing an optical waveguide by irradiating a laser beam onto an oxide single crystal material includes a means by which the scattering of light from the surface of the waveguide may be prevented when light is transmitted through the waveguide. A laser beam is irradiated onto an oxide single crystal to from an optical waveguide portion defined by laser working faces, which are then subjected to a wet etching process using, for example, a strong alkaline solution.Type: GrantFiled: June 6, 2002Date of Patent: December 28, 2004Assignee: NGK Insulators, Ltd.Inventors: Kenji Kato, Yoshimasa Kondo, Takashi Yoshino, Makoto Oomori

Patent number: 6827275Abstract: To track a large number of tools, the tools are kept in sets with each set having a container. A silhouette of each tool stored in the container is printed at the point of storage along with a data matrix symbology that has stored in binary code a description of the tool, the part number, and an identification of the kit of which it is a part. The associated tool has etched into the surface thereof a data matrix symbology containing the same information as the code printed at the point of storage. The data matrix symbology is readable by a scanner and a record of all the tools is maintained on a computer. Metal tools, may have a chrome, black oxide or stainless steel surface. To prepare the surface of a metal tool for receiving a data matrix symbology applied by a laser, the surface is sand blasted and coated with an suitable epoxy to inhance contrast.Type: GrantFiled: January 22, 2003Date of Patent: December 7, 2004Assignee: UFP Technologies, Inc.Inventor: Philip L.
