    Abstract: For complex CMP processes requiring the removal of different dielectric materials, possibly in the presence of a polysilicon material, a slurry material may be adapted at the point of use by selecting an appropriate pH value and avoiding agglomeration of the abrasive particles. The in situ preparation of the slurry material may also enable a highly dynamic adaptation of the removal conditions, for instance when exposing the polysilicon material of gate electrode structures in replacement gate approaches.

    Abstract: A surgical instrument comprising a symbol formed in or on a smooth surface surrounding the symbol, wherein the symbol comprises a plurality of angled surfaces over at least part of the area of the symbol, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol. These ridges and grooves create an improved contrast for the symbol relative to the surrounding surface by a combination of different specular reflection of incident light compared to the surrounding surface and shadows formed by the ridges and grooves. A method of marking a surgical instrument with a symbol formed in or on a smooth surface is also described. The method comprises forming a symbol in or on a smooth surface of the surgical instrument; and forming a plurality of angled surfaces over at least part of the area of the symbol, wherein the angled surfaces define a plurality of parallel ridges and grooves in the symbol.

  • Patent number: 8574032
    Abstract: Plastic restoration kits and methods for restoring the light transmission and optical clarity properties of plastic surfaces, such as plastic aircraft windows, automobile plastic headlight covers, plastic sunglass lenses, and plastic corrective optical lenses. The kits and methods restore plastic surfaces that have been damaged by hazing, scratching and/or UV-induced oxidation. The kits and methods employ at least one polishing composition configured to improve clarity by removing scratches. A UV protective material is incorporated into at least one of the polishing compositions so that the UV protective material becomes worked into the plastic surface during polishing, and a protective coating that forms a hard protective coating over the plastic surface impregnated with the UV protective material is finally applied. The plastic surface may be heated after polishing and prior to application of the protective coating material.

    Abstract: A seal assembly, adapted to seal a joint having a first member pivotable about a rotational axis relative to a second member thereof, includes first and second annular seal rings and first and second annular load rings. The first and second seal rings each has a loading surface, extending axially, and a sealing face, extending radially to an outer perimeter. Each sealing face has a sealing band disposed adjacent the outer perimeter. The first and second seal rings abut one another such that the sealing bands of the first and second seal rings are in contacting relationship with each other. The first and second load rings engage the loading surface of the first and second seal rings, respectively. Each sealing band is brush polished such that it has a surface roughness average of about 0.08 micrometers Ra or less.

  • Patent number: 8556682
    Abstract: A method of cleaving an optical fiber using a disposable abrasive film is disclosed. The method includes preparing an end of an optical fiber by exposing a length of the optical fiber. The exposed optical fiber is brought into contact with a tangential swipe formed of abrasive film to cause the optical fiber to cleave substantially at the location of contact leaving an optical fiber stub with a cleaved end. The optical fiber stub is polished with a polishing film having a coarse grit and may be polished a second time with a polishing film having a fine grit.

  • Publication number: 20130242468
    Abstract: A wet electrolytic capacitor that includes a porous anode body containing a dielectric layer, an electrolyte, and a cathode containing a metal substrate on which is disposed a conductive coating is provided. Prior to application of the conductive coating, the metal substrate is blasted with abrasive particles to enhance the ability of the substrate to adhere to the coating. The micro-roughened metal substrate can be treated after blasting so that substantially all of the abrasive particles are removed. This is accomplished by contacting the metal substrate with an extraction solution to remove the particles, and also by selectively controlling the nature of the abrasive particles so that they are dispersible (e.g., soluble) in the solution.
