Nonuniform Coating Patents (Class 427/256)
  • Patent number: 12005636
    Abstract: An additive manufacturing device performs manufacturing of an additively manufactured article by supplying a powder material to an irradiation region of an electron beam, laying and leveling the powder material, irradiating the powder material with the electron beam, and melting the powder material. The additive manufacturing device determines whether or not the powder material has scattered during manufacturing of the article. When it is determined that the powder material has scattered, an irradiation region R is heated by a heater before a new powder material is supplied to the irradiation region R. Manufacturing of the article is restarted after the new powder material has been supplied to the heated irradiation region.

Specifically, percolating films of MoS2 nanosheets with superlative electrical conductivity (10-2 s m?1) are achieved by tailoring the ink formulation and curing conditions. Based on an ethyl cellulose dispersant, the MoS2 nanosheet ink also offers exceptional viscosity tunability, colloidal stability, and printability on both rigid and flexible substrates. Two distinct classes of photodetectors are fabricated based on the substrate and post-print curing method. While thermal annealing of printed devices on rigid glass substrates leads to a fast photoresponse of 150 ?s, photonically annealed devices on flexible polyimide substrates possess high photoresponsivity exceeding 50 mA/W.

Paralleling a surface contour of the object being formed, the paths for two or more substantially continuous extruded traces are directed in complementary fashion to cause a first extrusion trace to form the object surface while a second extrusion trace is deposited behind the first trace. At another position along the surface contour, the paths of the extruded traces may cross over one another to allow the second extruded trace to define the object surface. Where the first and second traces have a different color or visual appearance, the disclosed mechanism enables fine graphic features to efficiently be integrated into the surface of the object being formed.

    Abstract: A method for fabricating patterns on a flexible substrate in a roll-to-roll configuration. Drops of a monomer diluted in a solvent are dispensed on a substrate, where the drops spontaneously spread and merge with one another to form a liquid resist formulation. The solvent is evaporated (e.g., blanket evaporation) from the liquid resist formulation followed by selective multi-component resist film evaporation resulting in a non-uniform and substantially continuous film on the substrate. The gap between the film on the substrate and a template is closed such that the film fills the features of the template. After cross-linking the film to polymerize the film, the template is separated from the substrate thereby leaving the polymerized film on the substrate.

  • Patent number: 11599022
    Abstract: Stabilized precursor solutions can be used to form radiation inorganic coating materials. The precursor solutions generally comprise metal suboxide cations, peroxide-based ligands and polyatomic anions. Design of the precursor solutions can be performed to achieve a high level of stability of the precursor solutions. The resulting coating materials can be designed for patterning with a selected radiation, such as ultraviolet light, x-ray radiation or electron beam radiation. The radiation patterned coating material can have a high contrast with respect to material properties, such that development of a latent image can be successful to form lines with very low line-width roughness and adjacent structures with a very small pitch.

  • Patent number: 11511307
    Abstract: A power storage device and an applicator is obtained that achieve an increase in capacity and an improvement in productivity, and that enable the thickness of a mixture layer to be inhibited from varying. A positive electrode mixture slurry is discharged into discharge regions of a belt-like positive electrode current collector that extend in a length direction of the positive electrode current collector from discharge nozzles corresponding to the respective discharge regions to form a positive electrode mixture layer on the positive electrode current collector. The discharge regions are arranged such that a part of each of the discharge regions overlaps a part of another of the discharge regions adjacent thereto when viewed in the length direction to form overlapping portions. The positive electrode mixture slurry is intermittently discharged to form an exposed portion on at least one of the discharge regions.

  • Patent number: 11491728
    Abstract: An optimal printing speed and orientation for an object to be manufactured using an additive manufacturing process in which a photo-curable resin is cured through exposure to radiation are estimated by determining, for pixel maps defining cross-sections of the object, a critical size of a convolution kernel which provides an activation map having a maximum activation pixel value less than or equal to a predetermined threshold value. For each respective pixel map, a printing time is estimated as a function of adjusted base lift velocity and base lift height of the printing apparatus. The optimal printing speed and orientation are then estimated as a minimum value of a sum of a function of printing times for all respective pixel maps of the cross-sections of the object at each of a plurality of possible orientations of the object.
