Methods for finishing a sputtering target to reduce particulation and to reduce burn-in time are disclosed. The surface of the unfinished sputtering target is blasted with beads to remove machining-induced defects. Additional post-processing steps include dust blowing-off, surface wiping, dry ice blasting, removing moisture using hot air gun, and annealing, resulting in a homogeneous, ultra-clean, residual-stress-free, hydrocarbon chemicals-free surface.

Systems and methods for cleaning a precipitator including plates and wires associated therewith using dry ice blasting equipment are described. The dry ice blasting equipment primarily includes an elongate wand. The elongate wand is configured to blast dry ice at a high level of pressure to ensure that debris and biproduct that is caked or coated onto the plates and wires is disengaged from the plates and wires. For instance, the dry ice may be blasted at pressures of at least 100 pounds per square inch, and more preferably at least 400 pounds per square inch. To achieve this pressure, the wand may be at least 2 feet in length, and more preferably at least 6 feet in length.

The invention relates to a method for reconditioning a remote control (1) with a housing consisting of an upper shell (2) and a lower shell (3), and a printed circuit board (21) carrying raised keys (5) for triggering control signals by pressure, the raised keys (5) penetrating the upper shell (2), said method comprising: removing (52) the upper shell (2) and the lower shell (3); blasting (55) at least one of the raised keys (5) on the printed circuit board (21) with an antibacterial abrasive; and inserting (58) the printed circuit board (21) with the raised keys (5) supported thereon between a new upper shell (2) and a new lower shell (3).

The present invention is embodied in a carbon dioxide compression and delivery device that uses a plurality of reversible thermoelectric devices and to a method to operate such carbon dioxide compression and delivery device.

An apparatus for wheel maintenance includes a base configured to rotate about a vertical rotational axis and a frame mounted to the base that has a pair of opposing longitudinal members and a pair of opposing transverse members. First and second rollers are spaced apart from one another and coupled to the pair of opposing transverse members. Both the first and second rollers rotate about a longitudinal rotational axis orthogonal to the vertical rotational axis. In this way, when a wheel is positioned on the first and second rollers, the wheel may be rotated about the vertical rotational axis and a wheel rotational axis during a maintenance procedure.

The present invention relates to a dry cleaning technology for a cleaning a surface of an object to be cleaned by adiabatically expanding liquid carbon dioxide to generate sublimable dry ice particles and carrying the dry ice particles on high-speed carrier gas to be sprayed onto the surface of the object to be cleaned, wherein an end of a liquid carbon dioxide nozzle further protrudes to the outside relative to an end of a carrier gas nozzle to prevent a growth of dry ice particles in the carrier gas nozzle, a hydrophobic coating is formed on a surface of the liquid carbon dioxide nozzle to prevent a formation of water droplets and to prevent an occurrence of irregular dry ice particles, thereby effectively preventing damage to a surface of an object to be cleaned and being advantageous in an economical aspect by significantly reducing consumption of liquid carbon dioxide.
