A method refurbishes structured surfaces of a component having a damaged subregion with material detachment. The method comprising: determining a reference region having a similar surface structure as the subregion; while pressing a die material onto the reference region: curing the die material to form a transparent die which is separable from the reference region without leaving residues and has a negative shape of the surface structure of the reference region; filling the damage location with electromagnetic irradiation curable material; placing the die onto the curable material in the damage location with an alignment of the negative shape of the transparent die corresponding to a desired surface structure at the damage location; while the die is being pressed onto the damage location: irradiating the curable material with electromagnetic irradiation through the transparent die until the material is cured; and removing the die from the cured material without leaving residues.

Disclosed herein is a method comprising transporting a conduit and a template through a guide tube; the template being disposed on an outer surface of the conduit between the conduit and the guide tube; and transferring a texture from the template to the conduit as the conduit and the template are transported through the guide tube. Disclosed herein too is an apparatus comprising a guide tube; the guide tube being operative to facilitate a transfer of a pattern from a template to a conduit; a first feed spool and a first take-up spool for feeding the conduit through the guide tube and for taking up the conduit after it has travelled through the guide tube respectively; and a second feed spool and a second take-up spool for feeding the template through the guide tube and for taking up the template after it has travelled through the guide tube respectively.

Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.

Methods, apparatus or equipment and systems for lining conduits, e.g., preferably subterranean pipelines and passageways, such as sewers, with a liner impregnated with a curable resin in order to secure the conduit against ingress or egress of liquids.

A bundle beam UV LED ultraviolet light sweeping method includes: activating electrical power to input into a PCB to light up a bundle beam UV LED ultraviolet light bead and driving a motor to cause a polygonal multiple-reflective-surface aluminum mirror to rotate, ultraviolet light from the UV LED being projected toward the reflective surface, and reflected by the reflective surface to change light direction for successive back-and-forth home-position-returning sweeping, the light converting from lines into sectorial shapes that are connected to form a large ultraviolet light operation region. The device includes a rotating device having a motor of which a spindle is mounted with a polygonal multiple-reflective-surface aluminum mirror; an UV LED bundle beam light source assembly having a bundle beam UV LED ultraviolet light bead fixed on a PCB; and a fixing base having a main body and a plurality of mounting braces.

A planarization system comprises a substrate chuck configured to hold a substrate, a superstrate chuck configured to hold a superstrate, a planarizing head configured to support the superstrate chuck, a positioning system configured to cause the superstrate to come into contact with formable material dispensed on the substrate to form a multilayer structure, the multilayer structure including the superstrate, a film of the formable material, and the substrate, and an annular light source disposed between an upper end of the planarizing head and the substrate chuck. The annular light source is configured to emit light onto an outer annular region of the multilayer structure without emitting the light onto an inner central region of the multilayer structure. The inner central region is located radially inward relative to the outer annular region.

A lens with an embedded foil is produced, comprising the steps of providing a first mold and a second mold, providing a functional foil, positioning and attaching the functional foil on the first mold, aligning the second mold relatively to the first mold, sealing the mold cavity between the first mold and the second mold, and filling a curable monomer mixture into the mold cavity, wherein either the molds are heated before the alignment step or the molds are heated after the sealing step and the following filling step is conducted with a heated monomer, or the heating of the molds follows the filling step of the UV curable monomer, followed by a UV curing step of the heated UV curable monomer mixture within the heated mold cavity.

A device and method for preparing a locally heterogeneous smart composite material based on time-frequency regulated SAWs are provided. The method includes: mixing functional particles, a photosensitive liquid and a photoinitiator evenly; inputting periodic time-frequency regulated sinusoidal signals defined by a frequency, a duration, an interval time and a time difference to a pair of slanted-finger interdigital transducers, such that the pair of slanted-finger interdigital transducers are excited to produce corresponding standing SAWs; coupling and allowing the standing SAWs to enter a liquid tank to form a local sound field in the photosensitive liquid; forming, by the functional particles in the photosensitive liquid, a stable array distribution under the action of an acoustic radiation force of the local sound field; and turning on an UV light source for curing, thereby completing the preparation.

An electrical wire includes a conductor and an insulating layer that covers the conductor and that is cross-linked. The insulating layer is a cross-linked product of a resin composition including (a) a base polymer containing polyolefin and a compatibilizer, (b) a photoradical generator of 0.5 parts by mass or more and 3 parts by mass or less relative to the 100 parts by mass of the base polymer, and (c) a reactive monomer of 1 part by mass or more and 5 parts by mass or less relative to the 100 parts by mass of the base polymer. A relative dielectric constant of the insulating layer is less than 2.5.
