Abstract: An apparatus for use in directing a flow of air with particles entrained therein toward a workpiece includes a nozzle and a deflector. The nozzle has a passage with a noncircular cross sectional configuration. The deflector has an outer side surface with a circular cross sectional configuration. A flow of air with particles of powder entrained therein is conducted along outer surface areas on the deflector at a first volumetric flow rate. A flow of air with particles of powder entrained therein is conducted along outer surface areas on the deflector at a second volumetric flow rate which is greater than the first flow rate. The deflector includes a porous member which is releasably connected with a main portion of the deflector to facilitate cleaning and provide access to the interior of the deflector. Seal members are provided between an electrode sheet, the porous member, and the main portion of the deflector.

Abstract: A computer system having a CPU, a power management processor, a switch, a modem, a timer, an override circuit, a glitch circuit, and a power supply in circuit communication. The power supply has several power supply states, which are controlled by the power management processor responsive to the CPU, the switch, the modem, the timer, the glitch circuit, the override circuit, and the power management processor itself.

Abstract: An air jet assembly supported over a polishing pad provides for raising flattened fibers pressed down by the polishing of semiconductor wafers and for blowing spent polishing materials and by-products off the pad. The polishing pad is supported on a rotatable platen and includes fibers which normally extend substantially perpendicular to an upper surface of the polishing pad. The fibers are coated with chemicals for polishing the surface of semiconductor wafers during the chip fabrication process. The fibers of the polishing pad tend to flatten down against the platen during the polishing process and spent polishing materials and by-products become embedded in the fibers of the pad. The air jet assembly is supported over the pad and includes an elongated pipe having an inlet port and a plurality of output ports. The inlet port is coupled to an air supply which forces air into the pipe and out through the outlet ports.
