A method and apparatus for extracting foreign objects from the nasal passageway of a patient. A DRAM semiconductor device is provided whose refresh characteristics are improved without deteriorating other characteristics. A first polysilicon active layer is disposed on the first insulating layer and a second polysilicon layer is disposed on a second region of the substrate. The receiver discards the reordered ATSC data or the normally ordered robust VSB data depending upon receiver type or user selection. The hollow locking ring further maintains a tight seal with the elastic projectile pouch.
