  • Publication number: 20200156446
    Abstract: A vent unit includes a bezel installed on a vehicle and formed in a ring shape with a flow hole at the center, and a spacer overlapping and coupled to the bezel and formed in a ring shape rotating relative to the bezel. The bezel has a plurality of first through-holes circumferentially spaced apart from one another, and the spacer has a plurality of second through-holes circumferentially spaced apart from one another such that conditioning air is discharged to an interior through the second through-holes and the first through-holes when the second through-holes are aligned with the first through-holes by circumferential rotation. The vent unit further includes a wing disposed in the flow hole of the bezel and coupled to the spacer through a hinge shaft. The wing controls discharge of conditioning air through the flow hole by axially rotating, and circumferentially relatively rotating together with the spacer.

  • Patent number: 10106424
    Abstract: A method of preparing silicon using silica includes placing silica in a reaction chamber; adding a reducing agent into the reaction chamber; feeding a material for impact into the reaction chamber and sealing the reaction chamber; and reducing the silica to silicon by allowing the material for impact to generate a physical impact inside the reaction chamber. The preparation method of silicon using silica does not employ a high-temperature high-pressure process and provides a preparation method of silicon by which the porous structure of the silica before a reduction reaction is maintained within the silicon even after the reaction.

  • Patent number: 9519139
    Abstract: A zoom lens barrel assembly includes a first barrel, a second barrel, a lens barrier, and a transparent member. The first barrel supports at least one lens. The second barrel surrounds at least a portion of an outer surface of the first barrel, and supports the first barrel to protrude along an optical axis direction. The lens barrier is disposed on a front side of the first barrel, and is moved in a direction that intersects an optical axis to expose the at least one lens when the first barrel is protruded. The transparent member is disposed on a front side of the lens barrier, and prevents impurities from entering the first barrel.
