Abstract: A fixing device for a cabinet, and the cabinet with such fixing device, hold vulnerable components steadily in place at all times. The cabinet includes a door panel, internal components, and at least one fixing device. The door panel defines at least one locking hole and supports at least one component. Each fixing device includes a telescopic portion and an operation portion and each telescopic portion is aligned with one locking hole. The operation portion is rotatable one way to extend the telescopic portion to abut and hold the component in place, and rotatable in the reverse direction to unlock and release the component.

Abstract: A structure of reduced profile to render crushproof a cabinet with the structure can be installed in an opening of the cabinet. The structure includes a first frame and a reinforcing portion. Two ends of the reinforcing portion are both connected to the first frame, so that the reinforcing portion is received in the first frame. The crush-proofing structure is movably connected to the opening of the cabinet.

Abstract: A structure for mounting servers includes at least one cross beam, at least one mounting column, and at least one fastening subassembly. A guide rail is fixed on each of the cross beam and extends along the cross beam. A first space is formed by the guide rail and the cross beam. The mounting column is connected to the cross beam by the fastening subassembly. The mounting column is perpendicularly connected to the cross beam by the fastening subassembly. The fastening subassembly comprises a first fastener which comprises a thumb screw and an extrusion subassembly. The extrusion subassembly is located in the first space and capable of moving back and forth along the cross beam. The thumb screw passes through the mounting column, enters into the first space, and matches with the extrusion subassembly to tighten the cross beam and the mounting column.

Abstract: An inbuilt but deployable supporting apparatus for supporting a server cabinet includes an extension arm and a supporting unit. The extension arm includes two opposite ends, one end of the extension arm is movably connected to a lower side of the server rack, the supporting unit is connected to the other end of the extension arm. The extension arm is movable between a retracted position, where the extension arm saves space by being accommodated in the lower side of the server rack, and a deployed position, where the extension arm is extended out of the server rack and, being adjustable in respect of the distance or depth down to a supporting surface, takes support from the supporting surface through the supporting unit.

Abstract: An adjustable hinge assembly includes a first hinge leaf, a second hinge leaf hinge-coupled to the first hinge leaf, and a hinge pin. The first hinge leaf defines a first knuckle hole corresponding to the hinge pin, and the second hinge leaf defines a second knuckle hole corresponding to the hinge pin. The first hinge leaf is hinge-coupled to the second hinge leaf by the hinge pin, the first knuckle hole, and the second knuckle hole. The hinge pin is movable within the first knuckle hole to adjust a position of the first hinge leaf relative to the second hinge leaf.

Abstract: A server cabinet includes a base plate, a number of sidewalls, a top plate, and a number of reinforcing ribs. The sidewalls are arranged surrounding the base plate and coupled between the top plate and the base plate to form a cavity. A portion of the sidewalls defines a number of receiving grooves. The reinforcing ribs are received within the receiving grooves and coupled to at least one of the sidewalls and the base plate.

Abstract: A structural column for a server includes a first bent portion, a second bent portion connected with the first bent portion, a third bent portion connected with the second bent portion, a fourth bent portion connected with the third bent portion, and a fifth bent portion connected with the fourth bent portion. The structural column is made from a single piece of flat sheet metal and the shapes of the bent portions and their respective interactions, without fasteners or other joining means, provide high strength and light weight.

Abstract: A method includes followings operations. A semiconductor substrate is provided. A photoresist is formed on the semiconductor substrate. Dopants are inserted into the photoresist to carbonize a portion of the photoresist. An etch steam is sprayed on the semiconductor substrate and the photoresist. A hole is formed at a surface of the photoresist by the etch steam. The etch steam is flowed into the hole so as to remove a portion of the photoresist at an interface between the semiconductor substrate and the photoresist. The photoresist is decorticated from the semiconductor substrate.
