  • Patent number: 9346126
    Abstract: A laser cutting apparatus (10) includes a laser processing head (15) that receives a laser beam emitted by a laser oscillator (12) and that uses a spherical lens for converging the laser beam so as to cause the intensity distribution of the laser beam to have a caldera-like shape, in which the intensity of the laser beam is higher in a peripheral area than in a central area, at the position of a workpiece (20). Moreover, the laser processing head (15) radiates the laser beam whose focal position is displaced from the position of the workpiece (20) to the workpiece (20). Therefore, the laser cutting apparatus (10) performs an inversion on the laser beam by using the spherical aberration of the spherical lens. Consequently, with a simple configuration, a laser beam whose inner area and outer area are inverted at the position of the workpiece (2) can be generated, and the processing direction for processing the workpiece (20) is not limited.

    Abstract: A method for making multiple single molecule receptors in a nanopore structure includes depositing a first material and a second material by a physical vapor deposition (PVD) technique onto different selected interior surfaces of a nanochannel and functionalizing a surface of the first material, the second material, or both the first and second materials with a chemical compound having at least two functional groups. The first and second materials can be the same or different and form patches having diameters of about 1 to about 100 nanometers (nm). Also disclosed are embodiments of a nanopore structure including multiple single molecule receptors.

  • Publication number: 20150093519
    Abstract: A process for stabilizing laser energy density on a target surface during pulsed laser deposition of thin films controls the focused laser spot on the target. The process involves imaging an image-aperture positioned in the beamline. This eliminates changes in the beam dimensions of the laser. A continuously variable attenuator located in between the output of the laser and the imaged image-aperture adjusts the energy to a desired level by running the laser in a “constant voltage” mode. The process provides reproducibility and controllability for deposition of electronic thin films by pulsed laser deposition.

  • Publication number: 20150086705
    Abstract: A light induced forward transfer manufacturing method provides for transfer of material from a donor sheet. A donor sheet is used that comprises a trench in a surface of the donor sheet, with transfer material in the trench. The material is transferred by scanning a light spot along the bottom of the trench. A donor sheet is used in which the average depth of the trench varies in the scanning direction. This supports optical reading of position information from the trench through the donor sheet and/or transfer of structures with predetermined height profiles from the trench. In combination with the average depth, or by themselves, a trench width, deviation of a trench from an average track or variation of a thickness or composition of material at a bottom of the trench may vary as a function of position along the trench to support optical reading of position information and/or transfer of predetermined structures.

  • Publication number: 20150086460
    Abstract: Provided is a method for producing a high-quality boron nitride film grown by using a borazine oligomer as a precursor through a metal catalyst effect. The method solves the problems, such as control of a gaseous precursor and vapor pressure control, occurring in CVD(Chemical vapor deposition) according to the related art, and a high-quality hexagonal boron nitride film is obtained through a simple process at low cost. In addition, the hexagonal boron nitride film may be coated onto various structures and materials. Further, selective coating is allowed so as to carry out coating in a predetermined area and scale-up is also allowed. Therefore, the method may be useful for coating applications of composite materials and various materials.

  • Patent number: 8962098
    Abstract: The objective of the present invention is to provide an unexpected method of manufacturing a battery electrode and a coating die for use therein, both of which are capable of providing a high speed drying and of improving a peel strength between a collector and a compound. The manufacturing process S1 of manufacturing the battery electrode 1 includes the process of coating the compound 3 containing the electrode active material 4 and the binder 5 on the sheet collector 2 and the process of drying the compound 3 to bond the collector 2 and the compound 3, wherein in the coating process, a laser light is emitted to the interface between the compound 3 and the collector 2. Due to the above structure, regardless of the drying speed, the binder 5 contained in the compound 3 is crystallized at the interface with respect to the collector 2. As a result, the high speed drying is provided and the peel strength between the collector 2 and the compound 3 is improved.

  • Patent number: 8962066
    Abstract: A method of repairing a component removes a prior coating from an underlying metal substrate. Small cooling air holes extend through the substrate and the coating that is to be removed. A new coating layer is placed on the metal substrate, and over the existing cooling air holes. The location of the cooling air holes is identified by inspecting the coated component for the location of indicators of the coating passing over the cooling air holes. The identified location of the indicators is used to control a cutting tool to remove any new coating from the cooling air holes. The basic method may also benefit new manufacture.

  • Publication number: 20150048281
    Abstract: An oxide film according to this invention is a film of an oxide (possibly including inevitable impurities) containing silver (Ag) and nickel (Ni). This oxide film is an aggregate of microcrystals, an amorphous form including microcrystals, or an amorphous form and has p-type conductivity, which exhibits no clear diffraction peak with the XRD analysis, as seen in a chart in FIG. 3 indicating X-ray diffraction (XRD) analysis results of a first oxide film and a second oxide film. This oxide film achieves a broader bandgap than that of a conventional oxide film as well as high p-type conductivity. This oxide film is an aggregate of microcrystals, an amorphous form containing microcrystals, or an amorphous form as described above, and is thus easily formed on a large substrate and is suitable also for industrial production.
