Abstract: The present disclosure relates to an electronic device, and more specifically, to an electronic device including a printed circuit board including a heat-generating element arranged on one surface thereof, and a heat transfer coin provided such that one surface of the heat transfer coin comes into contact with a portion of the other surface of the printed circuit board, opposite to the heat-generating element, so as to dissipate heat generated from the heat-generating element. Accordingly, the present disclosure provides an advantage of improving heat dissipation performance without increasing the thickness of the printed circuit board.

Abstract: A communication apparatus is provided to include an apparatus enclosure that includes a substrate seating surface and at least one or more connection grooves formed on the substrate seating surface, a first printed circuit board disposed on the substrate seating surface, a second printed circuit board disposed on the substrate seating surface on one side of the first printed circuit board, and at least one or more connectors disposed within the connection groove and configured to electrically connect the first printed circuit board and the second printed circuit board.

Abstract: Disclosed are a pressure vessel boss and a pressure vessel having same, the boss comprising: a boss body in which a through hole configured to connect an interior to an exterior of the pressure vessel is formed; and a boss joint portion which surrounds an outer surface of the boss body, radially extends outward, and has an outer surface coming into surface contact with and joined to an opening surface of a liner, wherein the outer surface has a cross-sectional shape having three or more line segments connecting a top to a bottom of the boss joint portion and including at least one convex corner and at least one concave corner.

Abstract: The present invention relates to a knob cap for a high-pressure tank including a coupling groove portion corresponding to a knob of a liner of the high-pressure tank formed in a lower surface of a body; a peripheral wing portion extending outward in a lower end of an outer circumferential surface of the body to be in contact with a surface of the liner; and a thickness conversion portion formed in the outer circumferential surface of the body to change a thickness between a center line and the outer circumferential surface.

Abstract: The present invention discloses a knob cap for a high-pressure tank including a first knob cap portion having a coupling groove coupled to a knob of a liner of the high-pressure tank in a lower surface, including a peripheral wing portion extending outward to be in contact with a surface of the liner to outside of a lower portion, and having a column portion in the shape of a column extending upward in a center; and a second knob cap portion integrally coupled with the first knob cap portion, having the column portion of the first knob cap portion inserted into a hollow, and including a plurality of inner grooves in the shape of a column having an upper end opened outside of the hollow and extending downward.

Abstract: The present invention relates to an impact beam having a structure in which a plurality of peak portions and a plurality of valley portions are repeatedly and alternately disposed, and including a reinforcement fiber that is continuously coupled to at least one of the plurality of peak portions and the plurality of valley portions along a length direction.
