Abstract: There is provided a biosensor capable of increasing a detecting sensitivity of a target substance of glutamate, by using a nano wire having excellent electrical characteristics and by immobilizing a receptor of glutamate to be detected on a substrate which is disposed between a nano wire and another nano wire and a method for manufacturing the same. The biosensor for detecting glutamate according to the present invention can be manufactured with an arrangement in which the nano wire is selectively arranged on a solid substrate in a matrix. Since this biosensor can prevent the degradation of the nano wire in the electrical characteristic, it can sensitively detect glutamate even through a small amount thereof is contained in a food so that it can be effectively used in detecting the food additive existing in the processed foodstuffs.

A biosensor according to the present invention can be manufactured with an arrangement in which the nano wire is selectively arranged on a solid substrate in a matrix and, therefore, many materials can be detected at the same time. Particularly, since the degradation of electrical characteristics of the nano wire can be prevented in the present invention, a target substance is very sensitively detected through a small amount thereof.

Abstract: Digital processing methods and apparatus for monitoring, controlling, and simulating industrial processes operate on data signals representative of process parameter values and generate response values representative of desired or requested process parameter values. A knowledge base stores knowledge of the industrial process in the form of rules, and an inference engine applied the rules to calculate the response values. A time-stamp value is assigned to each data signal, representing the time of receipt of each signal. Currency evaluation elements, responsive to user-selected currency range values and the time-stamp signals, assign an expiration-time value to the data signals and disregard data signals having an expiration-time value outside a corresponding user-selected currency range value.

Abstract: This invention is directed to resinous compositions which are generally metal-filled and which also contain hard filler materials. This combination produces unexpectedly better electrical conductivity than metal-filled material without the hard filler materials. Meanwhile there can be retained the resinous composition's ability to be quickly fabricated by simple molding technique into structurally sound rigid articles which are electrically conductive.

Abstract: Flame retardant, thermoplastic molding compositions of high electroconductivity comprising between about 2% and about 45% by weight of finely divided conductive carbon black particles substantially uniformly dispersed within a cementitious matrix having a chlorine content of at least about 24% by weight and composed predominantly of substantially thermoplastic resins not substantially less than half of which by weight are vinyl chloride polymers which have a vinyl chloride content of at least about 70% by weight and K-values between about 45 and about 70, and wherein said cementitious matrix also contains from about 1% to about 15% by weight of a well balanced lubricant/stabilizer combination comprising lubricants which are solid at temperatures up to at least about 50.degree. C., together with effective stabilizers, are disclosed.

Abstract: Flame retardant, conductive plastic molding compositions are provided in granular form comprising a thermoplastic resinous matrix through which are distributed fine, solid anisometrically shaped metallic particles in amounts totalling between about 12% and about 40% by volume. The formulation of said matrix is such that it contains at least about 24% by weight of chlorine derived primarily from vinyl chloride resins having K values between about 45 and about 70, and it also contains from about 3% to about 15% by weight of balanced lubricant/stabilizer combinations. Said anisometrically shaped metallic particles typically have aspect ratios of over about 10 to 1 and a minimum characteristic dimension of over 1 micron and are preferably composed almost entirely of conductive metal.
