  • Patent number: 7331306
    Abstract: A plasma processing method includes exhausting the interior of a vacuum chamber while supplying gas into the vacuum chamber while maintaining the interior of the vacuum chamber at a desired pressure. A high-frequency power of 100 kHz to 100 MHz is applied to a coil provided in the vicinity of a dielectric window which faces a substrate placed on a substrate electrode in the vacuum. Plasma is generated in the vacuum chamber to process the substrate or a film on the substrate. Particles which tend to move straight from a surface of the substrate or from a surface of the film on the substrate toward a wall surface of the dielectric window inside the vacuum chamber are kept interrupted by a metal plate.

  • Patent number: 7326303
    Abstract: This invention describes an apparatus, Scanning Localized Evaporation Methodology (SLEM) for the close proximity deposition of thin films with high feature definition, high deposition rates, and significantly improved material economy. An array of fixed thin film heating elements, each capable of being individually energized, is mounted on a transport mechanism inside a vacuum chamber. The evaporable material is deposited on a heating element. The SLEM system loads the surface of heating elements, made of foils, with evaporable material. The loaded thin film heating element is transported to the substrate site for re-evaporation. The re-evaporation onto a substrate, which is maintained at the desired temperature, takes place through a mask. The mask, having patterned openings dictated by the structural requirements of the fabrication, may be heated to prevent clogging of the openings. The translation of the substrate past the evaporation site permits replication of the pattern over its entire surface.

  • Patent number: 7311939
    Abstract: Substrates, such as spectacle lenses for example, may be provided with a coating which is not uniform by way of screens. The screens are aperture rings, arranged concentric to a symmetry axis of the vaporising crucible in a vacuum coating unit, by way of a screen holder. The spectacle lenses are disposed on a substrate holder also in circles about the symmetry axis. The shadows cast by the aperture rings cover but a partial region of the spectacles lenses such that those regions of the lenses receive less coating than in the unshaded free regions. The aperture rings are exchangeable in order to match the coating process to the customer requirements. Furthermore, the separation of the subtrate holder from the aperture rings is adjustable.

  • Patent number: 7270714
    Abstract: A surface treating process according to the present invention, a vapor deposited film is formed from an easily oxidizable vapor-depositing material on the surface of a work by evaporating the vapor-depositing material in a state in which the vapor deposition controlling gas has been supplied to at least zones near a melting/evaporating source and the work within a treating chamber. Thus, the vapor deposited film can be formed stably on the surface of a desired work without requirement of a long time for providing a high degree of vacuum and without use of a special apparatus. In addition, the use of the surface treating process ensures that a corrosion resistance can be provided to a rare earth metal-based permanent magnet extremely liable to be oxidized, without degradation of a high magnetic characteristic of the magnet.

  • Patent number: 7192624
    Abstract: Continuously operating furnace and method for obtaining thermal diffusion coating on the outside surface of metallic articles. The furnace is configured as a tunnel through which in succession are advanced closed containers filled with the processed articles and with powder mixture, containing diffusing specie. A chain conveyor, passing through the furnace, advances the containers along a transportation path. The furnace is provided with plurality of stopper means, capable to intermittently prevent the advancement of the containers and to retain them in discrete positions, situated along the transportation path. The containers advance in parallel being always directed perpendicularly to the transportation path and their retention in the discrete positions causes their rotation about their longitudinal axes. Continuous operation is associated with improved efficiency and increased capacity.

  • Patent number: 7155115
    Abstract: The invention concerns a device and a process for applying a lubricant by means of vapour deposition to a target object, especially a magnetic data carrier. The device in accordance with the invention comprises a lubricant supply means (1) that can be filled from outside, possibly by means of a feed line. The produced lubricant vapour (5) is expanded through one or more exit openings (6) in the direction of a target object (8) on which the vapour deposition is to be effected. The vapour at first becomes adsorbed on the walls of a cone-shaped distribution element (4) situated between the lubricant supply means (1) and the target object (8), from which it subsequently desorbs again. Said adsorption/desorption process assures an even and homogeneous vapour distribution over the target object (8). A device for interrupting the vapour supply makes it possible for the device to be operated in a discontinuous manner.
