Abstract: Disclosed herein is a nanocomposite composition having barrier properties. The nanocomposite composition is prepared by dry-blending a polyamide resin and a nanocomposite having barrier properties composed of polyamide and a layered clay. Since the nanocomposite composition has superior barrier properties and good moldability, it is suitable for use in the manufacture of closed containers, sheets having barrier properties, and films having barrier properties. Further disclosed is an article manufactured from the nanocomposite composition.

Abstract: The present invention relates to a nanocomposite blend composition having superior barrier properties, and more particularly to a nanocomposite blend composition comprising a polyolefin resin; one or more nanocomposites having barrier properties, selected from an ethylene-vinyl alcohol (EVOH)/intercalated clay nanocomposite, a polyamide/intercalated clay nanocomposite, an ionomer/intercalated clay nanocomposite, and a polyvinyl alcohol (PVA)/intercalated clay nanocomposite; and a compatibilizer. This nanocomposite blend composition has superior mechanical strength and superior barrier properties to oxygen, organic solvent, and moisture. Also, it has superior chemical barrier properties and is applicable to single/multi-layer blow molding and film processing.

Abstract: The method we invent is about finding patterns of images displayed in computers, generated by such as electrophoresis 2D gel, X-ray and CAT (computer assisted tomography) and applying for a diagnosis of a disease. To get patterns of images, first normalize the images and use knowledge-based machine to classify the set of images into two groups, normal and abnormal. The objective function obtained from the learning machine gives us a criterion to diagnose a disease.

Abstract: A semiconductor memory device for alternately selecting two groups of input/output lines according to a predetermined column address. A first group of a number of the input/output line pairs is driven by activation of any one of the selection signals within the first group, and a second group of a number of the input/output line pairs is driven by activation of any one of the selection signals within the second group. Furthermore, the input/output line pairs within the second group are precharged and equalized when the input/output line pairs within the first group are driven, and the input/output line pairs within the first group are precharged and equalized when the input/output line pairs within the second group are driven.

Abstract: A bit-line sensing control circuit includes a first circuit for activating a word line and a bit line associated with a first block of a memory cell array in response to a first initial activating clock. A delay circuit generates a second initial activating clock from the first initial activating clock a predetermined period after the first initial activation clock. A second circuit for activating a word line and a bit line associated with a second block of the memory cell array is initiated in response to the second initial activating clock. Because the second block of memory cells are sensed after the first block of memory cells, spike noise related problems are substantially avoided.

Abstract: The present method relates to molding metal particles by forming a flowable mixture. The metal particles are mixed with a polyorganic acid which chemically reacts with the metal particles. The flowable mixture is transferred to a mold before the chemical reaction between the metal particles and the polyorganic acid proceeds so far as to substantially increase the viscosity of the flowable mixture. A green preform is created by applying pressure to the mixture in a mold. The green preform is heated to a first temperature to vaporize substantially all of the non-organic components of the reacted polyorganic acid from the preform. The preform is then heated to a second temperature greater than the first temperature to sinter the metal particles.
