摘要: Embodiments of the invention provide a class of ethylene/α-olefin block interpolymers. The ethylene/α-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/α-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/α-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.3.

摘要: 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.

摘要: 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.

摘要: 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.
摘要翻译: 根据本发明的保持器(10)包括用于在其上支撑风扇(50)的基座(11),从基座垂直向上延伸的一对第一屏蔽件(14)和垂直延伸的第二屏蔽件(15) 从与第一屏蔽件相对的底座向上。 基座在其相对的相对侧处形成凸缘(16)和弹性突片(18),用于抵靠风扇的相对侧壁(52)。 每个第一和第二屏蔽件形成用于邻接风扇顶表面的门槛(26,27)。 因此,风扇容易且牢固地固定到保持器,保持器牢固地附接到计算机外壳。
