Abstract:
A method for producing a columnar or cylindrical metal automotive part whose outer circumferential surface includes a portion to be coated with paint and a portion to be uncoated therewith includes the following processes: (1) a process of providing a convergent nozzle-shaped covering jig which covers an outer circumferential surface of the columnar or cylindrical part at an axial end thereof and covers the portion to be uncoated with the paint, with a gap formed between the covering jig and the outer circumferential surface of the part; (2) a process of discharging a gas from the gap toward an end of a nozzle of the covering jig with the columnar or cylindrical part being rotated; (3) a process of sticking a film-forming substance to the columnar or cylindrical part from an axial side surface thereof.
Abstract:
The disclosure is related to a method for preparing an OLED display panel, comprising: providing a substrate; disposing a spray device above the substrate, and applying a forward voltage to the spray device; applying a reverse voltage to a section of the substrate on which organic material being going to be deposited, and applying a forward voltage outside the section; the spray device spraying organic material in fog form, such that the organic material in fog form depositing on the section. The disclosure further provides an OLED display panel prepared by the method. In the disclosure, sub pixels can be prepared without masks, the spray device sprays out the organic material in fog form by electro spraying, and a higher accuracy is not necessary for the spray device, which sprays by electro spraying, such that the cost is significantly decreased.
Abstract:
A golf ball comprising a layer formed from at least one of a thermoset material or a thermoplastic material throughout; the layer having a treated region and an untreated region; the treated region extending inward from an outer surface of the layer and comprising a UV resistance composition; and the untreated region not comprising the UV resistance composition. For example, the treated region may be infused with the UV resistance composition. The layer may be a cover or even an inner golf ball layer, which can sometimes become exposed during play. The UV resistance composition may be formed from a mixture of an ultraviolet light absorber (UVA) and a solvent, the UVA being selected from benzotriazole type stabilizers, hindered amine type stabilizers, phenolic type stabilizers, triazines, or combinations thereof, and the solvent comprising at least one of acetone, methyl ethyl ketone, methyl isobutyl ketone, ethyl acetate, or butyl acetate.
Abstract:
The inventions disclosed by this application are for a cladding apparatus, a cladding head, and a method of cladding a relatively planar solid object such as a boiler waterwall. Cladding of non-horizontal surfaces is complicated by the effects of gravity as melted clad material trends to runoff the surface before the cladding material bonds to the appropriate location. The disclosed inventions overcome these limitations by controlling the relative angle of application by either rotating the workpiece or the cladding head through a pre-programmed sequence. Also presented in a compact design for a laser cladding head that facilitates such cladding by minimizing movement of the laser fiber and improves cladding speed over irregular shaped objects.

Abstract:
The invention relates to a method of aligning magnetic flakes, which includes: coating a substrate with a carrier having the flakes dispersed therein, moving the substrate in a magnetic field so as to align the flakes along force lines of the magnetic field in the absence of an effect from a solidifying means, and at least partially solidifying the carrier using a solidifying means while further moving the substrate in the magnetic field so as to secure the magnetic flakes in the carrier while the magnetic field maintains alignment of the magnetic flakes. An apparatus is provided, which has a belt for moving a substrate along a magnet assembly for aligning magnetic flakes. The apparatus also includes a solidifying means, such as a UV- or e-beam source, and a cover above a portion of the magnet assembly for protecting the flakes from the effect of the solidifying means.

Abstract:
A method of applying particles to a backing having a make layer on one of the backing's opposed major surfaces. The method including the steps of: supporting the particles on a feeding member having a feeding surface such that the particles settle into one or more layers on the feeding surface; the feeding surface and the backing being arranged in a non-parallel manner; and translating the particles from the feeding surface to the backing and attaching the particles to the make layer by an electrostatic force.
Abstract:
Disclosed is a method of applying particles to a coated backing. A first layer of particles is created over a second layer of particles on a support surface and the first layer of particles is different in at least one property from the second layer of particles. A coated backing is positioned above the first and second layer of particles. An electrostatic field is applied simultaneously to the first and second layer of particles such that the first layer of particles closer to the coated backing are preferentially attracted to the coated backing first before the second layer of particles.
