Abstract:
A link scheduling method in a system for performing Device-to-Device (D2D) communication includes periodically collecting information indicating whether to perform a medium access from at least one neighboring link determining at least one link expected to perform a medium access in a corresponding traffic slot among links with a higher priority than the terminal based on the collected information, and determining whether to perform the medium access of the terminal by considering only the at least one link expected to perform the medium access.
Abstract:
A heat exchanger having an improved structure which allows refrigerant tubes to be firmly bonded to heat exchange fins. The heat exchanger includes a plurality of refrigerant tubes spaced apart from each other, headers coupled to both end portions of the refrigerant tubes, and heat exchange fins coupled to the refrigerant tubes and disposed spaced apart from each other. Each of the heat exchange fins includes insertion grooves allowing the refrigerant tubes to be inserted thereinto, and bonding plates bonded to the refrigerant tubes. Each of the bonding plates includes a first bonding portion curved from one end portion thereof in a first direction and bonded to one surface of a corresponding one of the refrigerant tubes, and a second bonding portion curved from the other end portion thereof in a second direction and bonded to the other surface of the corresponding one of the refrigerant tubes.
Abstract:
A semiconductor device includes first and second fin patterns on a substrate and extending apart from each other, a field insulating film on the substrate and surrounding parts of the first and second fin patterns, a first gate structure on the first fin pattern and intersecting the first fin pattern, a second gate structure on the second fin pattern and intersecting the second fin pattern, and a separating structure protruding from a top surface of the field insulating film and separating the first and second gate structures, the field insulating film and the separating structure including a same insulating material.
Abstract:
A heat exchanger includes a plurality of tubes having refrigerant flowing therein and arranged to exchange heat with outside air; and a header having a chamber adapted to distribute the refrigerant to the plurality of tubes, wherein the header includes, a base wall having a plurality of tube insertion holes into which the plurality of tubes are inserted, and a partition wall integrally formed with the base wall and configured to divide the chamber into a plurality of sections corresponding to the plurality of tubes. This structure helps reduce the number of parts of the heat exchanger, simplify processing and assembling, and improving the heat transfer performance by improving the distribution of the refrigerant.
