Abstract:
A case structure suitable for a server is provided, which includes a first plate and a second plate. A fixing pillar is disposed on the first plate, and the second plate has a fixing rack with a locking portion and an assembly spring with a lock cooperating hole for being penetrated by the fixing pillar. The locking portion is used to lock an engaging portion of the fixing pillar so as to fix the second plate to an assembly position. When the assembly spring is activated by forces and departs from the fixing pillar, the second plate can be shifted from the assembly position to a disassembly position and departs from the first plate.
Abstract:
An assembly and a heat-dissipating device having the same assembly are provided, in that tapped holes in fans of the heat-dissipating device are used with at least two columnar first fixing parts for mounting or detaching the heat-dissipating device with the need for extra tools. Accordingly, problems in the prior art may be solved.
Abstract:
A slide bearing supporting frame for supporting and mounting a slide bearing to a rack having locking holes, includes at least one locking part penetrating at least one of the locking holes and for being locked to the at least one of the locking holes of the rack via a fixer, for allowing the slide bearing frame to be fixed on a rack with locking holes of different sizes.
Abstract:
SRAM cells and SRAM cell arrays are described. In one embodiment, an SRAM cell includes a first inverter and a second inverter cross-coupled with the first inverter to form a first data storage node and a complimentary second data storage node for latching a value. The SRAM cell further includes a first pass-gate transistor and a switch transistor. A first source/drain of the first pass-gate transistor is coupled to the first data storage node, and a second source/drain of the first pass-gate transistor is coupled to a first bit line. The first source/drain of the switch transistor is coupled to the gate of the first pass-gate transistor.
Abstract:
A fan device includes a fan body having a connecting portion and two corresponding side portions, wherein each side portion is provided with at least a corner edge consisting of an aperture, a fan frame, a frame connecting end connecting with the connecting portion, a side wall for dividing the fan body, and a wrench having a wrench connecting end and an exerting end, wherein the wrench connecting end has two protrusion portions disposed on both side thereof. When installing the fan body in the fan frame, the exerting end is used to exert force to turn the wrench so that is abuts against a side wall thereof, thereby exerting force on the side wall and the exerting end to detach the connecting portion from the wrench connecting end.
Abstract:
A truncated glucanase with an improved thermal stability and a higher specific enzymatic activity than the wild-type enzyme. The truncated glucanase is obtained by removing a number of amino acid residues from the C-terminal of the wild-type 1,3-1,4-β-D-glucanase of Fibrobacter succinogenes. The removal of the C-terminal amino acid residues can be conducted at the genetic level by modifying the gene encoding for the wild type enzyme using, for example, a PCR-based method. Or, it can also be conducted at the protein level by first producing the wild-type enzyme protein and then subjecting the wild-type protein to certain protease action to remove a portion of its C-terminal.
Abstract:
A bracket structure is utilized to assemble an electronic device into a case. The bracket structure includes a main bracket, a side bracket, a pin, and a guiding groove. The main bracket has a chassis and a bracket wall. The electronic device would be assembled on the chassis. The side bracket would be disposed on a case wall of the case. The pin would be protruded on a surface facing the side bracket of the bracket wall. The guiding groove is disposed on the side bracket. The pin would slide in the guiding groove to guide the main bracket into the case.
Abstract:
A drawable housing structure is applicable to an electronic device for supporting a plurality of electronic components of the electronic device. The housing structure includes a main body for supporting the electronic components. The main body includes a front surface having an opening, and a top surface connected to the front surface and having a first opening. The housing structure further includes a handler. The handler includes a cantilever engaged with the first opening, and a rotatable fixing member engaged with the cantilever for buckling the opening. By drawing the rotatable fixing member the cantilever moves accordingly, and the housing structure can be took out from the electronic.
