Patents by Inventor Manfred Weiler

Manfred Weiler 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).

  • Recording media having protective overcoats of highly tetrahedral amorphous carbon and methods for their production
    Patent number: 6537668
    Abstract: The invention provides systems and methods for the deposition of an improved diamond-like carbon material, particularly for the production of magnetic recording media. The diamond-like carbon material of the present invention is highly tetrahedral, that is, it features a large number of the sp3 carbon-carbon bonds which are found within a diamond crystal lattice. The material is also amorphous, providing a combination of short-range order with long-range disorder, and can be deposited as films which are ultrasmooth and continuous at thicknesses substantially lower than known amorphous carbon coating materials. The carbon protective coatings of the present invention will often be hydrogenated. In a preferred method for depositing of these materials, capacitive coupling forms a highly uniform, selectively energized stream of ions from a dense, inductively ionized plasma.
    Type: Grant

  • Method of drying a filter cake and a press for carrying out the method
    Patent number: 6387282
    Abstract: The filter cake in a filter press is heated by direct contact with a heating plate opposite the pressing membrane so that a vapor phase is generated which moves uniformly in a planar pressure front through the filter cake to dry residual liquid therefrom. The filter cake is maintained under vacuum during the drying step.

  • Method for producing recording media having protective overcoats of highly tetrahedral amorphous carbon
    Patent number: 5858477
    Abstract: The invention provides systems and methods for the deposition of an improved diamond-like carbon material, particularly for the production of magnetic recording media. The diamond-like carbon material of the present invention is highly tetrahedral, that is, it features a large number of the sp.sup.3 carbon--carbon bonds which are found within a diamond crystal lattice. The material is also amorphous, providing a combination of short-range order with long-range disorder, and can be deposited as films which are ultrasmooth and continuous at thicknesses substantially lower than known amorphous carbon coating materials. The carbon protective coatings of the present invention will often be hydrogenated. In a preferred method for depositing of these materials, capacitive coupling forms a highly uniform, selectively energized stream of ions from a dense, inductively ionized plasma.
