  • Publication number: 20070205385
    Abstract: A slide valve, especially useful in a coating system for coating substrates in a vacuum, includes a housing formed from housing walls. An opening and a sealing surface surrounding the opening is provided in each of two opposing housing walls, with the openings forming a passage through the housing. At least one closing element with two sealing surfaces, is guided back and forth in a mobile manner crosswise to the passage in the housing between a rest position that releases the openings and a working position that completely overlaps the openings. An actuating force that acts on the closing element when the closing element moves into the working position applies a pressure to the sealing surfaces surrounding the openings of the housing walls, which pressure depends on the level of the actuating force. The coating system contains the slide valve.

  • Publication number: 20070171397
    Abstract: In the case of a method of detecting wind velocities by means of a Doppler-lidar system (10), a laser beam of a defined frequency generated by means of a laser (11) is emitted by a transmitting device (12) toward a space area and the light backscattered from the space area is received by means of a receiving telescope (13). For determining a Doppler shift, an interferogram is generated by means of an interferometer (16), the intensity distribution of the interferogram being directly measured by means of a photodetector (17). The measured intensity distribution is compared with one or more reference patterns which had previously been determined for defined parameters and are filed in a memory device (18a). From the comparison, the Doppler shift is determined as a measurement for the wind velocity. The Doppler-lidar system (10) comprises an analyzing unit (18a, 18b) for implementing the method, having a comparison unit (18b) for the comparison of reference patterns with the measured interferogram.

  • Publication number: 20060260914
    Abstract: A transport device is particularly suitable for use in a vacuum chamber for the transportation of a flat substrate through the vacuum chamber and comprises a belt conveyor with at least one flexible infinite belt guided around at least two deflection rollers, whereby at least one deflection roller can be driven, and further including a filling element positioned for filling at least the space contained by the infinite belt or belts. The air volume enclosed by the transport device is significantly reduced in comparison to conventional solutions by incorporating the filling element in the transport element. As a result, the volume to be evacuated from the vacuum chamber is reduced. The vacuum chamber can be evacuated and ventilated more rapidly. Nevertheless, the transport device is constructed so as to be maintenance-friendly. Maintenance work can be carried out easily, because the infinite belts and the deflection rollers are easily accessible.

  • Patent number: 6942768
    Abstract: A system for coating band-shaped material, where the band-shaped material travels through at least one process chamber in which there is a vacuum, and at least one cooling roller. On the peripheral surface of each cooling roller are at least two magnetron sputter sources that are arranged separate from one another in magnetron chambers, which are formed by separate magnetron chamber walls and allow each chamber to be evacuated, so the pressure in the magnetron chamber can be maintained higher than that in the process chamber. The magnetron chamber walls and the magnetron sputter sources can be mounted on a common carriage, which is displaceable parallel to the cooling roller axis. The result is the reduction in the maintenance costs in cleaning of the magnetron chamber walls and at the same time improvement of the separation of gas between the magnetron chambers and the process chamber.
