  • NANOPORE ELECTRODE, NANOPORE MEMBRANE, METHODS OF PREPARATION AND SURFACE MODIFICATION, AND USE THEREOF
    Publication number: 20080121534
    Abstract: Provided are fabrication, characterization and application of a nanodisk electrode, a nanopore electrode and a nanopore membrane. These three nanostructures share common fabrication steps. In one embodiment, the fabrication of a disk electrode involves sealing a sharpened internal signal transduction element (“ISTE”) into a substrate, followed by polishing of the substrate until a nanometer-sized disk of the ISTE is exposed. The fabrication of a nanopore electrode is accomplished by etching the nanodisk electrode to create a pore in the substrate, with the remaining ISTE comprising the pore base. Complete removal of the ISTE yields a nanopore membrane, in which a conical shaped pore is embedded in a thin membrane of the substrate.

    Abstract: Disclosed herein are various waterproof membranes that may be applied to a sill surface of an opening in a building structure to waterproof that surface as well as direct water that penetrates through the opening out of the structure. Generally, one or more flexible waterproof membranes are adhesively applied to the sill surface for purposes of waterproofing that surface. Such membranes may further incorporate a back dam structure that is disposed proximate to the rearward edge of a sill plate (i.e., disposed toward the interior of the structure) to direct water towards the front edge of the sill plate (i.e., toward the outside of the structure). Further, such membranes may include wicking material on one or more surfaces to allow for directing water out of a building structure. In various arrangements, one or more flexible membranes may be utilized to create an open fronted sill pan.

  • Support planar and tapered quasi-planar germanium waveguides for infrared evanescent-wave sensing
    Patent number: 7282105
    Abstract: Miniature planar IR waveguides of thickness 30–50 ?m, consisting of 12-mm long, 2-mm wide strips of Ge supported on ZnS substrates and tapered quasi-tapered waveguides, tapered from a thickness of 1 mm at the ends to a minimum of 1–100 ?m at the center, are disclosed. The surface sensitivity is increased as a function of incidence or bevel angle. The tapered waveguide improves the efficiency of the optical coupling both into the waveguide from an FTIR spectrometer, and out of the waveguide onto a small-area IR detector. The tapering makes it possible to dispense with using an IR microscope couple light through the waveguide, enabling efficient coupling with a detector directly coupled to an immersion lens. This optical arrangement makes such thin supported waveguides more useful as sensors, because they can be made quite long (e.g. 50 mm) and mounted horizontally.

  • Selectively roughening conductors for high frequency printed wiring boards
    Patent number: 7235148
    Abstract: A printed wiring board is formed from two or more layers, one of which has circuit lines formed thereon, and wherein the surfaces of the circuit lines are roughened only in areas that require good copper to laminate adhesion. The remainder of the circuit line surfaces are smooth. Thus, those areas for propagation of the signal on signal lines have the circuit lines smooth to maximize the signal propagation effect, while those areas where the signal propagation is not critical are rough, which improves the adhesion of one layer to another. On the voltage planes, the surface in those regions opposite the smooth surfaces of the signal planes is smooth. Thus, these areas of the voltage planes can be maintained smooth while the other areas of the surface of the voltage planes can be roughened, providing good adhesion to the adjoining dielectric material.

    Abstract: Methods for preparing a multi-layer acoustic transducer with reduced total electrical impedance. The methods are based on the stacking of individual piezoelectric layers with metallized surfaces to form a plate in which the metal layers are electrically connected to form interdigitated electrodes. The total electrical impedance of a multi-layer stack comprised of piezoelectric layers connected in this manner is inversely related to the square of the number of layers in the stack. This provides for better matching of the acoustic stack impedance to that of the electrical cable and improved acoustic element sensitivity.

  • Selectively roughening conductors for high frequency printed wiring boards
    Publication number: 20040007313
    Abstract: A printed wiring board is formed from two or more layers, one of which has circuit lines formed thereon, and wherein the surfaces of the circuit lines are roughened only in areas that require good copper to laminate adhesion. The remainder of the circuit line surfaces are smooth. Thus, those areas for propagation of the signal on signal lines have the circuit lines smooth to maximize the signal propagation effect, while those areas where the signal propagation is not critical are rough, which improves the adhesion of one layer to another. On the voltage planes, the surface in those regions opposite the smooth surfaces of the signal planes is smooth. Thus, these areas of the voltage planes can be maintained smooth while the other areas of the surface of the voltage planes can be roughened, providing good adhesion to the adjoining dielectric material.

  • Method of manufacturing a magnetic head
    Patent number: 6675464
    Abstract: A method of manufacturing magnetic heads is provided in which a slider and a back yoke are joined to form a magnetic head main body. The main body is then fixedly bonded to a holding member that supports the magnetic head as a single unit. A plurality of such magnetic heads are placed circumferentially on a soft adhesive sheet attached to a cylindrical base block. Touch lapping is then performed to a slider surface of the magnetic heads with a slurry on a surface table. Processing faces of the heads can be positioned flush with the surface table due to an elasticity of the soft adhesive sheet, thereby equally minimizing lapping amounts.

  • Method for regenerating brake linings
    Patent number: 6623581
    Abstract: In order to regenerate a brake lining, preferably for a railway vehicle, a friction lining is worked by machining, starting from its worn surface, and provided with a three-dimensional surface profile. The profiled surface is then coated with an agglutinant, and a fresh friction lining substance is pressed on. The worn surface is preferably worked by profile grinding or profile milling, such that a profiled surface structure is produced having a teeth-like, trapezoidal or meander-shaped profile that is vertical to the surface, wherein the profile depth of the surface structure lies in the region of approx. 1-30 mm, preferably 5-20 mm. The profile is preferably oriented in one direction, crosswise to the main strain of the friction lining during braking.
