The present invention provides bioactive bone cements that not only have sufficient radiopacity, low physiological toxicity, and requisite mechanism strength, but also promote local bone in-growth. The bone cement utilizes strontium salts as radiopacifiers, and comprises a powder component and a liquid component. In an embodiment, the powder component comprises a strontium salt, poly(methyl methacrylate) (PMMA), and a polymerization initiator; and the liquid component comprises methyl methacrylate (MMA) as reactive monomers and a polymerization accelerator.

A power supply mounting apparatus includes a chassis (40), a mounting board (20) attached to the power supply, and a mounting bracket (30). The chassis includes a rear panel (50) with an opening (52), and first and second side panels (50, 70). The mounting board forms a pair of mounting hooks (25) at each side thereof. The mounting bracket includes two mounting portions (31, 32) and a connecting portion (33). Each mounting portion defines slits (35) and locking holes (36). The rear panel forms catches slidably engaging in the locking holes. After the power supply slides in the chassis with the mounting hooks extending in the corresponding slits, the mounting bracket is moved horizontally so that the hooks hook the rear panel. The second side panel is attached to the chassis to prevent the mounting bracket from leaving the chassis.

A collimator capable of being reduced in its external size without sacrificing an aperture is to be provided. To this end, the collimator comprises a pair of first plate members which defines a radiation passing aperture by a spacing between respective opposed end faces, a pair of second plate members which respectively overlap the first plate members at least partially so as to block any other radiation than the radiation passing through the aperture, a pair of third plate members which respectively overlap the second plate members at least partially so as to block any other radiation than the radiation passing through the aperture, an adjusting mechanism which adjusts the aperture by moving the pair of first plate members, and a follow-up mechanism which causes the pair of second plate members to move following the pair of first plate members with movement of the first plate members.

A die attachment apparatus for attaching a semiconductor die onto a substrate having a metallic surface comprises a material dispensing station for dispensing a bonding material onto the substrate and a die attachment station for placing the semiconductor die onto the bonding material which has been dispensed onto the substrate. An activating gas generator positioned before the die attachment station introduces activated forming gas onto the substrate in order to reduce oxides on the substrate.

In certain embodiments, a method for bandwidth allocation includes receiving at least a first traffic flow and a second traffic flow, each traffic flow including at least committed information rate (CIR) and excess information rate (EIR) parameters. The CIR parameter in each traffic flow is associated with a corresponding guaranteed pass-through rate. The first traffic flow and the second traffic flow are stored in first and second queues, respectively. The first queue is associated with a first provisioned weight, and the second queue is associated with a second provisioned weight. The method further includes scheduling downstream transmission of the first traffic flow and second traffic flow stored in the first and second queues according to at least first and second implementation weights that are determined based on a bandwidth of a downstream communication link, a CIR parameter of the first queue, a CIR parameter of the second queue, and each of the first and second provisioned weights.

A fixing mechanism includes a chassis (400) with a plurality of fasteners (450) formed therein. A tray (100) is movably disposed in the chassis for supporting a printed circuit board (PCB) (10) which defines a plurality of apertures (13). The fasteners are relatively sliding in the apertures of the PCB respectively. The tray includes misaligned first and second driven portions (116, 138) at an end. A driving piece (200) is rotatably fixed in the chassis adjacent the end of the tray. The driving piece is generally positioned between the first and second driven portions of the tray initially, and the driving piece is rotated in a vertical plane to selectively drive the first and second driven portions to move the tray in a horizontal plane such that the fasteners clasp or unclasp the PCB.

A device includes a main body and a control circuit received in the main body. The main body includes three push buttons and a display. The control circuit includes a parameter setting unit, a rotation speed detection unit, and a display unit. The push buttons are operated to input signals to the parameter setting unit. The parameter setting unit generates and saves a reference value according to the signals received from the push buttons, and outputs the reference value to the display unit. The rotation speed detection unit detects an actual rotation speed of a fan, and outputs the actual rotation speed to the display unit. The display unit controls the display to display the reference value and the actual rotation speed.
