Abstract: Embodiments of the invention provide a class of ethylene/?-olefin block interpolymers. The ethylene/?-olefin interpolymers are characterized by an average block index, ABI, which is greater than zero and up to about 1.0 and a molecular weight distribution, Mw/Mn, greater than about 1.3. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block ethylene/?-olefin interpolymer is characterized by having at least one fraction obtained by Temperature Rising Elution Fractionation (“TREF”), wherein the fraction has a block index greater than about 0.3 and up to about 1.0 and the ethylene/?-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.3.

Abstract: A disk drive bracket fastening structure includes identical first and second disk drive brackets (30, 30′). She first bracket includes a rack (32) and a cover board (34) secured to the rack. The rack defines a pair of grooves (43) in a bottom panel (36) thereof, and forms a fixing portion (47) between the grooves. The cover board has a pair of rails (53) stamped upwardly therefrom. A fixing tab (55) is formed at a free edge of the cover board between the rails. In assembly the first bracket is firstly secured into a computer enclosure (10). The rails (53′) of the second bracket are then slid into the grooves of the first bracket. The fixing tab (55′) of the second bracket abuts against the fixing portion of the first bracket, and is fastened thereto. The second bracket is thereby firmly secured to the first bracket.

Abstract: A computer enclosure (10) includes a front panel (20) and a pivotable bracket (40). The front panel defines an opening (24) for providing access to the bracket, and a pair of screw holes (30) on opposite sides of the opening respectively. A pair of first ears (26) extends from the front panel at each side of the opening. The bracket includes a front wall (42) and a pair of side walls (44) perpendicular to the front wall. A pair of second ears (48) extends from the side walls and pivotally attached to the first ears of the front panel. A pair of locating tabs (54) extends from the front wall and each tab defines a through hole (56) therein, corresponding to and engaging at the screw holes of the front panel by bolts. The bracket is thereby secured to the front panel.

Abstract: A holder (10) in accordance with the present invention includes a base (11) for supporting a fan (50) thereon, a pair of first shields (14) extending vertically upwardly from the base, and a second shield (15) extending vertically upwardly from the base opposite the first shields. The base forms a flange (16) and a resilient tab (18) at respective opposite sides thereof, for abutting opposite side walls (52) of the fan. Each first and second shield forms a sill (26, 27), for abutting a top surface of the fan. The fan is thereby easily and firmly secured to the holder, the holder being securely attached to a computer enclosure.

Abstract: An enclosure includes a front panel (12), a pivotable bezel (14) and a pair of female hinges (16). A pair of male hinges (42) extends from one side of an inner surface of the bezel. Each male hinge includes a flange (4220) and a pivot column (4240). Each female hinge includes a rear wall (68) attachable to the front panel, and an engaging portion (61) extending perpendicularly from the rear wall. The engaging portion defines a groove (634), and a notch (630) spaced from the groove. The groove receives the flange of the corresponding male hinge. A recess (6302) is defined at the notch, for rotatably receiving the pivot column of the corresponding male hinge. The bezel further forms a catch (44), for engaging with a slot (202) of the front panel. The bezel is thereby easily and securely attached to the front panel.
