A method for manufacturing a golf ball having a non-uniform dot pattern is provided. Firstly, a semi-finished product of a golf ball is provided, which includes a ball body and a base layer covering an outer surface of the ball body. After that, the semi-finished product of the golf ball is rotated at a predetermined rotation speed, and a color paint is applied to the semi-finished product of the golf ball in a spraying manner from each of an upper position and a lower position.

A process for manufacturing continuous ceramic tape includes steps of heating a ceramic feedstock to a molten state and spraying molten droplets of the feedstock onto a deposition surface. The method further includes forming a ceramic coating on the deposition surface by accumulating the droplets, which solidify and are directly bonded to one another. The deposition surface is non-stick with respect to the ceramic coating such that the coating may be peeled off of the deposition surface as a continuous ceramic tape, without fracture. Additionally, in embodiments, the deposition surface is removed by running the deposition over a bending edge, chemically stripping or dissolving the deposition surface, or burning the deposition surface.

An improved slingshot band having a tapered outer contour. The slingshot band has a tubular body having a first fork end and a second pouch end. The tubular body comprises a first layer of an elastic polymer. The first layer has a constant thickness. The tubular body further comprises a second layer of an elastic polymer. The second layer has a greater thickness near the fork end of the tubular body and lower thickness near the pouch end of the tubular body. The increased thickness of the section of the tubular body near the fork end of the slingshot band reinforces the most vulnerable section of the slingshot band against failure, thereby extending its longevity.

A vessel has a lumen defined at least in part by a wall. The wall has an interior surface facing the lumen, an outer surface, and a plasma-enhanced chemical vapor deposition (PECVD) coating set supported by the wall. The PECVD coating set comprises a water barrier coating or layer having a water contact angle from 80 to 180 degrees, applied using a precursor comprising at least one of a saturated or unsaturated fluorocarbon precursor having from 1 to 6 carbon atoms and a saturated or unsaturated hydrocarbon having from 1 to 6 carbon atoms. Optionally, the coating set includes an SiOx gas barrier coating or layer from 2 to 1000 nm thick, in which x is from 1.5 to 2.9 as measured by x-ray photoelectron spectroscopy (XPS), and optionally other related coatings.

Provided is a CNT film coated substrate in which CNT is fixed to a substrate using a click reaction, so that a CNT film is uniformly formed with a high density and adhesive strength between the CNT film and the substrate is excellent to have high stability to water or an organic solvent. In the case of the conventional CNT film which was manufactured by spin coating, most of CNT was peeled off in a washing process, but in the case of the CNT film coated substrate according to the present invention, a high-density uniform CNT film coated substrate may be manufactured even after washing, and reproducibility between substrates may be secured.

A system for printing PSA on a substrate includes a rigid support structure. The system also includes a plurality of dispensing heads disposed within the rigid support structure and configured to deposit PSA solution on the substrate in response to applied pressure. Each dispensing head of the plurality of dispensing heads includes a support structure and a wicking structure disposed within the support structure and configured to hold the PSA solution, wherein the wicking structure is configured to deposit the PSA solution in a desired shape on the substrate upon contact with the substrate.

The present disclosure relates to a manufacturing process of a silicone glove, the silicon glove is divided into a liner, a glove blank and a silicon layer from the inside to the outside, and liquid silicon is sprayed on a surface of the glove blank for once; when spraying the liquid silicon, the glove blank also rotates around its axis while horizontally moving on an assembly line; during spraying, a liquid silicon outflow channel at least includes a finger gap spraying port and a tiger mouth spraying port that are arranged fixedly; an arranging length of the finger gap spraying port is greater than or equal to a length of a finger area of the glove blank; an arranging length of the tiger mouth spraying port is greater than or equal to a length of a tiger mouth area of the glove blank.

A coating layer for a substrate includes a coating material. The coating material includes graphene and/or graphene derivatives that reflect and/or absorb an electromagnetic (EM) wave having a frequency of above 20 GHz. The coating layer is deposited on a surface of the substrate.

A coating material of the present invention is a coating material containing: a fluorine-containing polymer having at least one of an iodine atom and a bromine atom; and a solvent, wherein a storage elastic modulus G′ of the fluorine-containing polymer is less than 360 kPa, and a total light transmittance of a mixed liquid obtained by mixing and stirring the fluorine-containing polymer and the solvent contained in the coating material is 1.0% or more, the mixed liquid being left to stand for 3 days, stirred again, and left to stand for 30 minutes to measure the total light transmittance.

A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.
