An integrated circuit package with a fully-exposed heat sink is provided. The integrated circuit package includes a substrate having a first side being formed with first conductive traces and a second side being formed with second conductive traces. At least one chip is mounted on the substrate and electrically connected to the first conductive traces. A plurality of solder balls are provided at the terminal ends of the second conductive traces to allow external connection of the chip. The fully-exposed heat sink is mounted on the substrate. The heat sink is formed with a plurality of supportive legs arranged in such a manner as to allow a bottom surface of the heat sink to be separated from the chip and a top surface of the heat sink to be tightly attached to a cavity in a mold used to form an encapsulant for enclosing the chip. A plurality of positioning tongues are formed on the heat sink for securing the heat sink in position when performing a molding process for forming the encapsulant. With this integrated circuit package, no jig is required in the assembly of the integrated circuit package. Moreover, since there is no need to use adhesives to adhere the supportive legs onto the substrate, the integrated circuit package would not suffer from delamination as in the case of the prior art. The fully-exposed heat sink allows an increased heat-dissipating efficient as compared to the prior art.

The present invention relates to a silencer for reducing muzzle blast and noise of firearms or similar devices. The present silencer has a hollow cylindrical or other shape casing comprising front and rear end caps and an opening aligned along a longitudinal axis defining a passage for a projectile and propellant gases to emerge from the muzzle opening. A plurality of serially placed baffles of symmetrical or slanted orientation and intervening coaxial spacers are positioned within the casing and define a multitude of chambers among the baffles, spacers, and outer housing. The baffles shear propellant gases away from the projectile path and through openings or ports into additional chambers formed between the spacers and outer housing. The arrangement of baffles and spacers provides flow-impeding paths, dispersion, and controlled expansion of gases and lowers gas temperature to reduce audible noise and observable signature of the muzzle blast.

A limited flash-over electric power switch uses a dielectric gas regulator and a flash-over arrestor to greatly diminish the occurrences of high voltage flash-over during operation of a circuit interrupter. The dielectric gas regulator prevents the flow of the dielectric gas into the arc gap during an initial portion of the opening stroke of the interrupter contacts. Once the arc gap is sufficiently wide to greatly diminish the likelihood of a high voltage flash-over, the dielectric gas regulator allows the dielectric gas to flow into the arc gap to extinguish the arc. The flash-over arrestor snubs out incipient flash-over that may occur as the arc attempts to reform across the arc gap. The flash-over arrestor may be a conductive ring located on the interior surface of the nozzle in the region of the orifice.
