  • Publication number: 20150257623
    Abstract: A dishwasher having a tub defining a treating chamber, a dish rack, and a spray assembly associated with the dish rack. The spray assembly may include at least one sprayer positioned to spray treating liquid onto dishes received by the rack. The sprayer has two openings and may be movable between a first position where the treating liquid flows through the first liquid opening into the treating chamber and does not flow through the second liquid opening and a second position where the treating liquid flows through the second liquid opening into the treating chamber. The sprayer may be rotatable between positions and may emit spray in both positions.

  • Patent number: 6737738
    Abstract: A high density, low profile, three dimensional memory module having multi-level semiconductor packages mounted on one or opposite sides of a printed wiring board. Each multi-level package of the memory module contains an upper level DRAM integrated circuit package that is surface mounted on the printed wiring board and at least one lower level DRAM integrated circuit package that is surface mounted on the printed wiring board below the upper level package, such that the upper and lower level packages are stacked one above the other. The upper level package is preferably a thin small outline package, and the lower level package is preferably a leadless chip scale package. The leads of the upper level package are of sufficient length so that the standoff height of the upper level package establishes a clearance thereunder in which to receive the lower level package.

  • Patent number: 6189346
    Abstract: A clothes treating apparatus including a cabinet defining an interior region in which a garment can be hung. A door is movably connected to the cabinet for closing the interior region. A fluid atomizing nozzle is supported by the cabinet and is fluidly connected to a reservoir containing a conditioning composition. An air compressor is connected to the nozzle for supplying air to the nozzle such that when the air compressor is energized the conditioning composition is drawn out of the reservoir and sprayed from the nozzle in a mist form into the interior region. A fan is provided for circulating air within the interior region such that the mist form of the conditioning composition is uniformly distributed onto the garment hanging within the interior region. Accordingly, the clothes treating apparatus provides a means for applying a conditioning composition onto garments which does not include means for supplying steam into the interior region.
