Abstract: The present disclosure describes micromechanical devices and methods for using such devices for characterizing a material's strength. The micromechanical devices include an anchor pad, a top shuttle platform, a nanoindenter in movable contact with the top shuttle platform and at least two sample stage shuttles. The nanoindenter applies a compression force to the top shuttle platform, and the at least two sample stage shuttles move apart in response to the compression force. Each of the at least two sample stage shuttles is connected to the top shuttle platform and to the anchor pad by at least one inclined beam. Methods for using the devices include connecting a sample between the at least two sample stage shuttles and applying a compression force to the top shuttle platform. Application of the compression force to the top shuttle platform results in a tensile force being applied to the sample. Measuring a tip displacement of the nanoindenter is correlated with the sample's strength.

Abstract: Method and apparatus for handling a supported tubular string with a string elevator and a spider on a rig to prevent damaging contact between the string elevator and spider while facilitating further connections of add-on tubular segments. The string elevator and supported tubular string descend toward the spider until reaching a predetermined position. The process of setting the spider into engagement of the tubular string is automatically initiated in response to detecting the predetermined position of the string elevator. With the spider set, the string elevator can be unloaded. Optionally, the method may also automatically terminate the string elevator descent in response to detecting that the spider has been set. A preferred apparatus for detecting the position of the elevator includes a tilt switch secured to a fixed position along the length of the Kelly hose.

Abstract: A method is provided for creating a plurality of substantially uniform nano-scale features in a substantially parallel manner in which an array of micro-lenses is positioned on a surface of a substrate, where each micro-lens includes a hole such that the bottom of the hole corresponds to a portion of the surface of the substrate. A flux of charged particles, e.g., a beam of positive ions of a selected element, is applied to the micro-lens array. The flux of charged particles is focused at selected focal points on the substrate surface at the bottoms of the holes of the micro-lens array. The substrate is tilted at one or more selected angles to displace the locations of the focal points across the substrate surface. By depositing material or etching the surface of the substrate, several substantially uniform nanometer sized features may be rapidly created in each hole on the surface of the substrate in a substantially parallel manner.

Abstract: High-directivity microstrip antennas comprising a driven patch and at least one parasitic element placed on the same plane, operate at a frequency larger than the fundamental mode of the driven patch in order to obtain a resonant frequency with a high-directivity broadside radiation pattern. The driven patch, the parasitic elements and the gaps between them may be shaped as multilevel and/or Space Filling geometries. The gap defined between the driven and parasitic patches according to the invention is used to control the resonant frequency where the high-directivity behavior is obtained. The invention provides that with one single element is possible to obtain the same directivity than an array of microstrip antennas operating at the fundamental mode.

Abstract: The present invention is directed to micro- and nano-scale imprinting methods and the use of such methods to fabricate supported and/or free-standing 3-D micro- and/or nano-structures of polymeric, ceramic, and/or metallic materials. In some embodiments, a duo-mold approach is employed in the fabrication of these structures. In such methods, surface treatments are employed to impart differential surface energies to different molds and/or different parts of the mold(s). Such surface treatments permit the formation of three-dimensional (3-D) structures through imprinting and the transfer of such structures to a substrate. In some or other embodiments, such surface treatments and variation in glass transition temperature of the polymers used can facilitate separation of the 3-D structures from the molds to form free-standing micro- and/or nano-structures individually and/or in a film.

Abstract: A change-over mechanism causing a main support frame and a sub support frame to rotate is made up of a drive motor, a rotating body, and coupling rods. One end of the coupling rod is coupled to the rotating body, and the other end thereof is coupled to the main support frame. One end of the coupling rod is coupled to the rotating body, and the other end thereof is coupled to the sub support frame. When a belt junction conveyor is changed over between a first and a second transfer states, one of the coupling rods is pushed out and the other one is pulled by the rotating body rotating by an activation of the drive motor, so that the main and the sub support frames are rotated in the opposite direction from each other, and a direction of transport of products by an endless belt is changed over.
