  • Patent number: 7141866
    Abstract: An imprinting apparatus and method of fabrication provide a mold having a pattern for imprinting. The apparatus includes a semiconductor substrate polished in a [110] direction. The semiconductor substrate has a (110) horizontal planar surface and vertical sidewalls of a wet chemical etched trench. The sidewalls are aligned with and therefore are (111) vertical lattice planes of the semiconductor substrate. The semiconductor substrate includes a plurality of vertical structures between the sidewalls, wherein the vertical structures may be nano-scale spaced apart. The method includes wet etching a trench with spaced apart (111) vertical sidewalls in an exposed portion of the (110) horizontal surface of the semiconductor substrate along (111) vertical lattice planes. A chemical etching solution is used that etches the (111) vertical lattice planes slower than the (110) horizontal lattice plane. The method further includes forming the imprinting mold.

  • Publication number: 20060256335
    Abstract: The present invention provides beam-shaping optics for transforming an approximately gaussian beam profile into a (nearly) uniform distribution over a specified spot area. The beam-shaping optics provide significant advantages over existing beam-shapers in that they are less sensitive to variations in the input beam profiles and can be used over a range of frequencies.

  • Publication number: 20060243957
    Abstract: Various embodiments of the present invention are directed to a binary signal converter that facilitates distinguishing an original direct signal on a nanowire by superimposing an alternating signal on the original direct signal. The binary signal converter includes an alternating signal source connected to the nanowire that superimposes an alternating signal with an initial amplitude on the nanowire. The binary signal converter may also include a selective alternating signal filter that selectively passes the alternating signal from the nanowire to a signal sink.

  • Patent number: 7107885
    Abstract: A tool handle self-contained a set of screwdriver bits includes a handle and a set of screwdriver bits in the handle. There is a fixed hole provided on the bottom of the handle and a receiving groove provided on the side of the handle. The set of screwdriver bits includes a base, a pillar installed on the base and a plurality of holding parts installed on the base. On the upper end of the pillar, a step portion is provided and each holding part holds a screwdriver bit. After the set of screwdriver bits and the receiving groove are assembled, the bottom of the base and the handle become a smooth surface and the top face of the pillar in the hole of the receiving groove forms a pressing face. If the pressing face is pressed, the set of screwdriver bits will move out from the handle. After the screwdriver bit is locked at the bottom of the handle, it can act as screwdriver. A tool handle self-contained a set of screwdriver bits can suit for various hand tools.

  • Publication number: 20060189112
    Abstract: Embodiments of the present invention are directed to methods for fabricating microscale-to-nanoscale interfaces. In numerous embodiments of the present invention, hybrid microscale/nanoscale crossbar multiplexers/demultiplexers provide for selection and control of individual nanowires through a set of microscale signal lines. In order to overcome the difficulty of aligning nanowires with submicroscale and microscale signal lines, at least a portion of the interconnections between nanowires and sub-microscale or microscale signal lines are randomly generated by one of various connection-fabrication methods. Addresses for individual nanowires, or groups of nanowires, can be discovered by testing the microscale-to-nanoscale interfaces.

  • Patent number: 7090477
    Abstract: An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw. Stationary parts of the motors are fastened on a frame and forward-backward moving unit, not moving during injection and metering. Due to the arrangement of the moving parts and the injection screw on a single axis, moving parts are lessened, and transmission losses are minimized. Since the number of structural parts is low, only the moving parts of the motors move during injection while the stationary parts thereof remain at rest, thus greatly reducing inertia.

  • Patent number: 7087946
    Abstract: A method for forming first and second linear structures of a first composition that meet at right angles, there being a gap at the point at which the structures meet. The linear structures are constructed on an etchable crystalline layer having the first composition. First and second self-aligned nanowires of a second composition are grown on this layer and used as masks for etching the layer. The self-aligned nanowires are constructed from a material that has an asymmetric lattice mismatch with respect to the crystalline layer. The gap is sufficiently small to allow one of the structures to act as the gate of a transistor and the other to form the source and drain of the transistor. The gap can be filled with electrically switchable materials thereby converting the transistor to a memory cell.
