摘要:
A coated abrasive article comprises an abrasive layer secured to a backing. The abrasive layer comprises abrasive particles secured by at least one binder to a first major surface of the backing. A supersize is disposed on at least a portion of the abrasive layer. The coated abrasive article has a melt flow zone adjacent to an edge of the coated abrasive article, wherein the melt flow zone has a maximum width of less than 100 micrometers, and the melt flow zone has a maximum height of less than 40 micrometers. Methods of using infrared lasers to ablate coated abrasive articles are also disclosed, wherein a laser wavelength is matched to a component of the coated abrasive article.
摘要:
A system for generating a laser machined tool from a substantially cylindrical work piece. The system includes a laser producing a laser beam, a mask positioned within the laser beam for shaping the laser beam into an image, and an optical system for imaging the laser beam image onto the outer surface of the work piece. The system coordinates rotational and translation movements of the work piece with activation of the laser in order to use the laser image for ablating the outer surface of the work piece, creating microstructures within the surface of the work piece to form the cylindrical tool.

The systems, methods, and apparatuses of the present disclosure generally describe the use of one or both of human-readable information and machine-readable information printed on, adhered to, or adjacent to an object (e.g., a license plate or sticker), where at least a portion of the machine-readable information performs or assists in performance of at least one of the following functions: (a) correlating to license plate information stored in a remote lookup table; and (b) duplicating information about the license plate.
摘要:
Tamper indicating articles that include a surface-feature image-generating layer and an adhesive layer are described. The surface-feature image-generating layer generates a visible, surface-feature-generated image upon exposure to light. The intensity of the surface-feature-generated image is reduced when taped-over. Single-image and dual-image tamper indicating articles are also described, including buried dual-image and adjacent dual-image tamper indicating articles.
摘要:
Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multi-photon polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness.
摘要:
A method for circuit fabrication includes positioning first and second webs of film in proximity to each other, wherein the second web of film defines a deposition mask, and deposition material on the first web of film through the deposition mask pattern defined by the second web of the to create at least a portion of an integrated circuit.
摘要:
Aperture masks and deposition techniques for using aperture masks are described. In addition, techniques for creating aperture masks and other techniques for using the aperture masks are described. The various techniques can be particularly useful in creating circuit elements for electronic displays and low-cost integrated circuits such as radio frequency identification (RFID) circuits. In addition, the techniques can be advantageous in the fabrication of integrated circuits incorporating organic semiconductors, which typically are not compatible with wet processes.
摘要:
A receptor medium with a sheet having an optically transmissive microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire' effects but also provides sufficient optical transmissivity to be useful as overhead transparency media, backlit signage, and the like. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire' effects. Methods of making and using the inkjet receptor medium are also disclosed.
