Abstract: A multilayer electronic component according to an example embodiment may include: a body including dielectric layers and internal electrodes; and an external electrode including a connection portion, and a band portion extending from the connection portion, wherein the external electrode may include an electrode layer connected to the internal electrode and including a first conductive metal and glass, a conductive resin layer disposed on the electrode layer and including a second conductive metal and a resin, and a silver (Ag) coating layer disposed between an electrode layer and a conductive resin layer of the band portion, and an average thickness of the silver (Ag) coating layer may be 2 ?m or more and 5 ?m or less.

Abstract: An air extractor grille duct includes: an air extractor grille configured to be selectively opened due to a pressure difference between the interior and exterior of a vehicle so that interior air is discharged; a duct housing connected to the air extractor grille and configured to provide a discharge path for the interior air; and a sound-absorbing cover connected to the duct housing, provided with an inclined surface, and configured to guide discharged interior air to flow along the inclined surface toward the discharge path.

Abstract: An article withdrawing system for withdrawing articles held in a packing box, the upper surface of which is opened. A first stage holds the packing box carried with the opened upper surface and reverses the packing box so that the articles held in the packing box falls down. A second stage supports and holds the falling-down articles. The first stage includes a support unit supporting and moving the packing box upward and downward, a box holding frame in which the support unit is mounted, a linear movement frame to which the box holding frame is rotatably coupled, a main frame in which the linear movement frame is coupled and supported to be linearly moved and is located and supported on the ground, and a first rotation driving mechanism disposed in the linear movement frame and for rotating and driving the box holding frame.

Abstract: An ozone asher includes: a chamber having a closed space isolated from an atmosphere, and an opening through which the semiconductor substrate to be etched is inserted and withdrawn from the chamber; an upper cover forming an upper portion of the chamber, having ozone injection holes for supplying ozone into the chamber; a plurality of holders for holding the semiconductor substrate inserted in the chamber through the opening; a pedestal provided to be raised and lowered in the chamber and supporting the semiconductor substrate during the whole procedure; vacuum means provided at the pedestal for drawing and holding the semiconductor substrate to the pedestal; heating means for the semiconductor substrate provided at the pedestal; means for raising and lowering the pedestal and the heating means; means for keeping a gap between the pedestal and the upper cover during the elevating of the semiconductor substrate; and a slit door for opening and closing the opening of the chamber selectively.
