  • Publication number: 20070283575
    Abstract: The device is a hand-held, ergonomic-friendly pull-cut tool for opening transparent thermoformed (heat-sealed plastic) over-packaging that encapsulates small consumer products. Consumers find it difficult to remove these thermoformed “clamshells.” Our package opener with pivoting blade guard safely and effectively removes these thermoformed enclosures by piercing and slicing the plastic in one smooth motion.

  • Patent number: 7033406
    Abstract: An electrical-energy-storage unit (EESU) has as a basis material a high-permittivity composition-modified barium titanate ceramic powder. This powder is double coated with the first coating being aluminum oxide and the second coating calcium magnesium aluminosilicate glass. The components of the EESU are manufactured with the use of classical ceramic fabrication techniques which include screen printing alternating multilayers of nickel electrodes and high-permittivitiy composition-modified barium titanate powder, sintering to a closed-pore porous body, followed by hot-isostatic pressing to a void-free body. The components are configured into a multilayer array with the use of a solder-bump technique as the enabling technology so as to provide a parallel configuration of components that has the capability to store electrical energy in the range of 52 kW·h. The total weight of an EESU with this range of electrical energy storage is about 336 pounds.

  • Patent number: 6836185
    Abstract: A modulator driver design is disclosed that employs a differential pair amplifier coupled to feedback amplifiers through tuning networks. Each tuning network comprises a set of inductors that enables a broadband response while reducing the loading effect of the feedback amplifier. An active load is placed at the output to serve multiple purposes, including: generating a high output swing, enabling a lower power supply voltage, and allowing the entire bias circuit to be monolithically integrated.

  • Patent number: 6664842
    Abstract: The present invention is a circuit comprising two series-coupled field effect transistor (FET) devices with a resistor network coupled in parallel forming a composite device (that can be substituted directly for a single FET device). In applications such as active loads or current sources, the composite device exhibits a greater breakdown voltage and superior high-frequency characteristics. The resistor network provides optimum direct current (DC) bias for depletion mode devices and superior high-frequency loading. Bandwidth and stability are both increased. Furthermore, this circuit is compatible with depletion mode FET processes having a single fixed threshold voltage.

  • Publication number: 20030181558
    Abstract: The invention relates to novel crosslinkable carboxylated nitrile rubber compositions that also comprise a multivalent salt of an organic acid and a peroxide crosslinking agent. The compositions may also contain nitrile rubber in admixture with the carboxylated nitrile rubber. The rubber may be hydrogenated. Cured compositions made from the crosslinkable compositions display improved properties, particularly an unexpectedly high modulus.

  • Patent number: 6602962
    Abstract: Disclosed herein is a process for the production of hydrogenated nitrile rubber. The appearance of corrosion in the plant equipment in which hydrogenated nitrile rubber is produced is due to the unexpected presence of relatively large amounts of HCl, generated, surprisingly, by the hydro-dehalogenation of the monochlorobenzene solvent under the reaction conditions. The addition of a compatible weakly basic additive, such as Epoxidized Soy Bean Oil (ESBO), to the reaction mixture has alleviated this serious problem.
