摘要:
A semiconductor device including a doped substrate of a first doping polarity and a doped semiconductor material of a second doping polarity. The semiconductor material is on, or in, the substrate, and the second doping polarity is opposite the first doping polarity such that the semiconductor material and the substrate form a diode. The semiconductor device further includes an inductor on or above the semiconductor material, and a pattern in the semiconductor material for reducing eddy currents. The pattern includes a doped semiconductor material of the first doping polarity and a least one trench within the doped semiconductor material of the first doping polarity, wherein, at least at a depth at which the trench is closest to the inductor, the doped semiconductor material of the first doping polarity fully surrounds the trench so that, at least at the depth, the trench does not touch the doped semiconductor material of the second doping polarity.

A method and apparatus for the casting of metal components is disclosed. The apparatus includes a gooseneck for drawing molten metal from a crucible of hot metal and for forcing the drawn molten metal through the system, a hot runner assembly having a hot runner tip positioned adjacent the mold cavity, and a machine nozzle inserted between the gooseneck and the hot runner assembly. The gooseneck is fitted with a one-way check valve to allow for molten metal to be drawn into the plunger but to stop its passage out of the gooseneck when the metal is forced through the system into the die. A thermal valve is formed within the hot runner tip to provide a metal blockage from the molten metal which prevents the back-flow of molten metal back into the hot runner assembly. Both temperature and flow rate are carefully monitored and controlled.

A locker for securing one or more tensioning members includes a locker body having a first aperture, a second aperture, and a passageway extending therebetween. A pin is coupled to the locker body so as to traverse the passageway and is movable between a latent condition wherein the tensioning members are movable with respect to the locker body, and an activated condition wherein the tensioning members are prevented from moving relative to the locker body. A method of using a suture locker includes delivering the suture locker to a surgical site via a catheter assembly and actuating the pin so as to move the locker from the latent condition to the activated condition.

A window regulator includes a rotatable hub that is coupled to a traveller by a cable, such that rotation of the hub raises and lowers the traveller. The hub is mounted on a driven gear which is rotated by a drive gear. The hub and the driven gear are concentrically mounted around a post, which defines an outer surface that is frictionally engaged by a coil spring that is coupled both to the driven gear and to the hub. The coil spring brakes rotation of the hub when the traveller is pushed downwardly. The drive gear and its associated bushings are removably mounted on the window regulator to allow easy replacement.
