  • Patent number: 6465306
    Abstract: One aspect of the present invention relates to a method of forming a non-volatile semiconductor memory device, involving the sequential or non-sequential steps of forming a charge trapping dielectric over a substrate, the substrate having a core region and a periphery region; removing at least a portion of the charge trapping dielectric in the periphery region; forming a gate dielectric in the periphery region; forming buried bitlines in the core region; and forming gates in the core region and the periphery region.

  • Patent number: 5596880
    Abstract: A beverage container adapted to hold ice and beverages separate from water formed from melted ice includes a receptacle having an interior cavity for holding ice and beverages; a float having a density less than water adapted to support the ice and beverages and move upwardly within the cavity as the ice melts; a cover mounted on the receptacle by a hinge having three slots including a recess and an opening at a depth in the recess, and a tubesign base having three tabs having distal ends, lobes on the distal ends and lengths from bases of the tabs to their lobes corresponding to the depth, so as to enable removable attachment of the tubesign base to the hinge by insertion of the tabs in the slots, with the lobes locking the tabs into the slots when inserted therein.

  • Patent number: 5433085
    Abstract: A container for holding ice and beverages includes a receptacle having an interior cavity with substantially vertical side walls, and a float positioned within the cavity to support beverages and ice, and move upwardly within the cavity as ice melts. Ribs may be added to the interior wall of the cavity to prevent tipping of the float.

  • Patent number: 4987465
    Abstract: An ESD protection device for CMOS integrated circuit inputs is disclosed. Two clamp components, coupled by a current limiting device, couple the pad to the circuitry of the chip. The device prevents damage to the circuit from an ESD of approximately 8000 or more volts at an input terminal.

  • Patent number: 4780263
    Abstract: Accurate and consistent location of jointed textiles within a mold is achieved by inserting the outer surfaces of the joint (12) into the cavity of an elongate, generally U-shaped member (20) and securing the joint to the meter, e.g. by sewing (21). The joint/channel member assembly can then be automatically gripped and placed in the desired position in the mold. The method is of particular application to processes involving vacuum member molding.
