  • Patent number: 11047160
    Abstract: A door mounting system for sliding translation of a door in one embodiment may include a longitudinally elongated support rail defining a mounting axis, a pair of wall mounts rigidly anchoring the support rail to a support surface, a door bracket slideably movable along the support rail, a door supported by the door bracket in a suspended manner, and a linear roller bearing disposed at an interface between the door bracket and support rail to facilitate movement of the door bracket along the support rail. The door is linearly translatable along the support rail in operation between open and closed positions. In one embodiment, an anti-sway clip disposed on the door bracket defines a stop surface configured to engage the support rail to arrest swaying motion of the door if a force is inadvertently applied to the door acting in a plane oriented transversely to the mounting axis.

  • Patent number: 9349417
    Abstract: An electronic apparatus includes an apparatus casing, using a cover mechanism, and a device unit, disposed inside the apparatus casing. The apparatus casing includes a casing body, a pivotal device, a pivot locking mechanism, and a door. The casing body structurally constrains the door to move in a direction at a side of the casing body. After sliding, the door is engaged with the pivotal device and drives the pivot locking mechanism to unlock the pivotal device so that the door can rotate to another side of the casing body by the pivotal device relative to the casing body. A manipulation area of the casing body is therefore exposed. Thereby, a user can manipulate the device unit through the manipulation area; the inner surface of the door keeps facing toward the casing body so that the apparatus casing can keep its aesthetic appearance.

  • Patent number: 8974692
    Abstract: Provided are novel chemical mechanical polishing (CMP) slurry compositions for polishing copper substrates and method of using the CMP compositions. The CMP slurry compositions deliver superior planarization with high and tunable removal rates and low defects when polishing bulk copper layers of the nanostructures of IC chips. The CMP slurry compositions also offer the high selectivity for polishing copper relative to the other materials (such as Ti, TiN, Ta, TaN, and Si), suitable for through-silicon via (TSV) CMP process which demands high copper film removal rates.

  • Publication number: 20140026359
    Abstract: Example trolleys and hangers for washdown curtains are disclosed herein. An example trolley disclosed herein includes features that simplify manufacturing and promote liquid runoff to avoid bacterial growth. Some example trolleys comprise U-bolts, shoulder screws and acorn nuts. In some examples, a frame of the trolley has a nestable V-shape profile that makes the frame readily blanked and formed from sheet metal with minimal waste. In some examples, an example trolley disclosed herein has a pair of rollers that are horizontally offset to a point from which the curtain hangs so that the weight of the curtain tilts the trolley to promote liquid runoff from the trolley's frame.
