Abstract: A cover for covering an opening of a socket formed by a housing comprises a body; one or more bosses extending from the body, a first locking mechanism, a second locking mechanism, and a release tab. The bosses movably couple the body to the housing such that the body is movable between first and second positions. The first locking mechanism releasably attaches to the housing to secure the body in the first position. The second locking mechanism releasably attaches to the housing to secure the body in the second position. The release tab aids in detaching the first locking mechanism from the first wall and the second locking mechanism from the second wall. When the body is in the first position, the body allows access to the socket through the opening. When the body is in the second position, the body prevents access to the socket through the opening.

Abstract: A release mechanism is disclosed that can facilitate safely and efficiently removing an expansion card from a computing device. The release mechanism can be installed on a motherboard around an expansion slot, and can include an opening that permits access to the expansion slot to allow an expansion card to be installed therein. When removal of the expansion card is desired, a handled of the release mechanism can be pulled, causing contact surfaces of the release mechanism to push the expansion card away from the expansion slot with even force, removing the need to tilt the expansion card.

Abstract: A wrench includes a driving unit located in the head of the wrench. A rod extends through the driving member and includes a stepped recess so as to control a bead in the radial hole of the driving member to secure a socket connected to the driving member. A rotary member is connected to the head and includes a room. A locking member is located in the room and locked to the driving member. A fixing area is formed between the locking member and the driving member so as to fix the locking member and the driving member together. The fixing area ensures that locking member is not separated from the driving member.

Abstract: The present disclosure describes a method to form alignment marks on or in the top layer of an extreme ultraviolet (EUV) mask blank without the use of photolithographic methods. For example, the method can include forming a metal structure on the top layer of the EUV mask blank by dispensing a hexacarbonylchromium vapor on the top layer of the EUV mask and exposing the hexacarbonylchromium vapor to an electron-beam. The hexacarbonylchromium vapor is decomposed to form the metal structure at an area which is proximate to where the hexacarbonylchromium vapors interact with the electron-beam. In another example, the method can include forming a patterned structure in the top layer of an EUV mask blank with the use of an etcher aperture and an etching process.
