Abstract: Proposed is a wind turbine blade with a lightning protection receptor. The wind turbine blade with a lightning protection receptor is a technology that allows for excellent lightning capture rate for both negative and positive lightning by improving lightning measures for conventional wind turbines, which are vulnerable to positive lightning, in line with the increasing wind turbine heights for large-scale power generation and the trend toward offshore wind power, and that minimizes post-repair/supplementary measures by limiting blade damage/coating peeling due to lightning strikes to a narrow area, unlike in the conventional case where damage or peeling of the coating occurs over the entire area of a blade when struck by lightning on an edge wire inserted into the lateral inner side of the blade.

Abstract: The present disclosure relates to a category 6 (C6) unshielded twisted pair (UTP) cable satisfying plenum-rated high flame retardancy. Specifically, the present disclosure relates to a highly flame-retardant UTP cable that satisfies the plenum-rated highly flame-retardant characteristics of NFPA 262 standard, while implementing the electrical characteristics required in C6 UTP cables, and for which manufacturing costs can be greatly reduced.

Abstract: An air purifier filter is proposed. The air purifier filter includes: a filter body having an inlet and an outlet therein such that air flows therethrough, and a receiving space having formed therein; a substrate provided in the receiving space of the filter body; and activated carbon attached to a surface of the substrate, wherein the substrate has a three-dimensional corrugated structure.

Abstract: Provided is a composition for a heat-shrinkable tube, comprising: a base resin; and a flame retardant, wherein the base resin comprises chlorinated polyolefin resin and polyolefin elastomer, wherein the chlorinated polyolefin resin comprises chlorine in an amount of 30 to 40% by weight based on the total weight thereof, and the polyolefin elastomer has a melting point of 95 to 120° C., and an amount of the chlorinated polyolefin resin is 40 to 60 parts by weight and an amount of the polyolefin elastomer is 20 to 40 parts by weight, based on 100 parts by weight of the base resin.

Abstract: A semiconductor device includes a substrate including a conductive region, an insulating layer disposed on the substrate and including an opening exposing the conductive region, and a conductive layer buried within the opening and including a first region disposed on inner side walls of the opening and a second region disposed within the first region. The first region includes a plurality of first crystal grains and the second region includes a plurality of second crystal grains. The pluralities of first and second crystal grains are separated from each other at a boundary formed between the first and second regions.

Abstract: Disclosed herein is a canister mounted in a vehicle to reduce the discharge of fuel gas. The canister of the present invention includes at least one pocket installed in a canister housing. The pocket divides the inner space of the canister housing into first and second spaces. A heater is inserted into the pocket from the outside of the canister housing. The heater generates heat during running of an engine to heat active carbon filled in the canister. When the active carbon is heated, fuel gas adsorbed onto the active carbon in a liquid phase is easily evaporated and supplied to the engine. The heater can significantly improve desorption efficiency of the fuel gas by the active carbon.
