  • Patent number: 9238267
    Abstract: Cutting insert made of hard metal, cermet or ceramic substrate body with multi-layer coating applied thereto by CVD methods. The coating has a total thickness of 5 to 40 ?m and, starting from the substrate surface, has one or more hard material layers, an alpha aluminum oxide (?-Al2O3) layer of a layer thickness of 1 to 20 ?m and optionally at least portion-wise over the ?-Al2O3 layer one or more further hard material layers as decorative or wear recognition layers. The ?-Al2O3 layer has a crystallographic preferential orientation characterized by a texture coefficient TC (0 0 12)?5 for the (0 0 12) growth direction. The ?-Al2O3 layer has an inherent stress in the region of 0 to +300 MPas, and the substrate within a region of 0 to 10 ?m from the substrate surface has an inherent stress minimum in the region of ?2000 to ?400 MPas.

  • Patent number: 7085649
    Abstract: Electronic organiser (10) with a calendar (11) in which appointments at least according to date, time and an individual description, for example a person to be visited, are variable. If the organiser (10) is provided with an interface (22) which can exchange data in respect of the appointments with an interface (22) existing on another device (21), the data recorded in the calendar (11) can be used to run the other device or the electronic organiser (10) can be controlled by the other device. Thus for example data recorded in the calendar (11) can be used by a navigation system for faster input of the destination, or for example departure appointments can be changed by the other device according to the traffic or other situations.

  • Patent number: 7019832
    Abstract: An optical spectrometer comprises at least two coupling apertures with different mode field diameters, a means for dispersing the light beams exiting each of the coupling apertures along a dispersion axis and at least two decoupling apertures on which the dispersed light beams are imaged and whose mode field diameters each correspond to the mode field diameters of the associated coupling apertures. Due the enlarged mode field diameter, a larger spectral fraction of dispersed light beams, i.e., light of a larger spectral bandwidth, can be coupled into the decoupling aperture than into the decoupling aperture.

  • Patent number: 6856726
    Abstract: In a light waveguide, the one end of which comprises a flat entering area for the light to be coupled into the core of the light waveguide, the entering area is narrower than the core diameter of the light waveguide and, around the entering area, the end of the light waveguide is laterally sloped up to the entering surface. Only the light which impinges on this entering area passes into the core and is guided therein.

  • Patent number: 6690468
    Abstract: An optical spectrum analyzer of novel design, in which several different spectra can be measured and analyzed simultaneously. A measuring signal is used as a reference signal for calibrating the optical spectrum analyzer. The light rays are admitted via a coupling device with several coupling apertures arranged in a line; and via a separate decoupling device comprising respective decoupling apertures arranged in a line, the light rays are decoupled. Height offset is realized by a 90° deviation prism. The arrangement makes possible simultaneous analysis of several optical lines with little retroreflection as well as uninterrupted calibration of the measuring process.
