Wolfgang Fukarek has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220205079
    Abstract: The invention relates to the proposal of an electrode arrangement in a device for carrying out processes of physical vapor deposition that greatly reduces or even prevents the degradation of the electrode material caused by accretions. The contamination of the anode occurring in these processes due to cathodic carbon is minimized or prevented by the application of a thin adhesion-reducing coating of high electrical conductivity to the anode, which coating has poorer adhesive properties with regard to the coating material than the uncoated anode material. This coating is preferably a nitride coating, particularly preferably of TiN, applied with a coating thickness of between 0.1 ?m and 3.5 ?m.

  • Patent number: 9297065
    Abstract: A treatment installation for vacuum treatment of a front side of strip substrates includes first and second process chambers, each process chamber including a process roller and at least one process source. A transfer chamber arranged between the process chambers is coupled with both process chambers and can be separated in terms of pressure from at least one of the process chambers. The transfer chamber further includes an unwinding device with a removable unwinding reel and a winding-up device with a removable winding-up reel for the substrate and an outside air lock for loading and unloading the unwinding reel and/or winding-up reel. The rear side of the substrate faces the two process rollers and can be guided through the transfer chamber from the unwinding device to the first process roller, from the first process roller to the second process roller and from the second process roller to the winding-up device.

  • Patent number: 8475635
    Abstract: Deposition processes and devices for the fabrication of multilayer systems to better control the energy contribution at different stages of the deposition. This is achieved by depositing films by sputtering in a scheme providing for thermalized particles. Thermalized particles are obtained by choosing the working gas pressure and the distance between target and substrate to result in a mean free path of particles smaller than the distance between target and substrate or to result in a product of pressure and distance being larger than 2.0 cmPa.

  • Patent number: 8025777
    Abstract: It is in the object of the present invention to improve current deposition processes and devices for the fabrication of multilayer systems to better control the energy contribution at different stages of the deposition. This is achieved by depositing films by sputtering in a scheme providing for thermalized particles. One can get thermalized particles by choosing the working gas pressure and the distance between target and substrate to result in a mean free path of particles smaller than the distance between target and substrate or to result in a product of pressure and distance being larger than 2.0 cmPa.

  • Publication number: 20080247046
    Abstract: Proposed is a glare free pan for a rear view service in motor vehicles, possessing a curved transparent substrate, the front surface of which forms the exposed surface of the said mirror. Upon the rear surface of said substrate is applied, in appropriate thicknesses, by sputtering at least four successive and contiguous layers of respectively niobium pentoxide, silicon dioxide, chromium and a protect covering of lacquer. The chromium layer provides the effective reflecting quality of the said mirror. The composition and thicknesses of the layers allows the mirror to reflectively function in visible light wavelengths suitable for both night and day service. Proposed also is a method for the manufacture of the above as well as its assembly into a rear view mirror ready for vehicle installation.

  • Publication number: 20080053373
    Abstract: At least one shielding device, which protects the vacuum chamber walls and/or the components arranged in the chamber from undesired deposits of the layer starting material is arranged in the vacuum chamber of a coating installation according to the invention in which vitreous, glass-ceramic and/or ceramic layers are applied to substrates by deposition from the gas phase. It is important that in the event of temperature changes in the vacuum chamber, the expansion or contraction of the shielding device corresponds to the expansion or contraction of the vitreous, glass-ceramic or ceramic layer or deposits.
