Abstract: To provide a modified recycled polyester resin that has stable moldability, is capable of producing as a by-product only a small amount of gel-like material during the process of modification to allow stable cross-linking reaction, and can prevent the possibility of recleavage, and to provide a molded article using the same. The modified recycled polyester resin contains a recycled PET resin having a carboxyl group, and a modifying agent having an epoxy group and an oxazoline group, ends of the carboxyl group of the recycled PET resin being modified with the modifying agent, wherein a mole ratio between the oxazoline group and the epoxy group is within a range of 100:90 to 100:0.01, and an additive amount of the modifying agent is 0.001 to 15 parts by mass with respect to 100 parts by mass of the recycled PET resin.

Abstract: A rust inhibitor usable for metal surface coating includes, as an effective component, a compound containing a chelate group, and a long chain alkyl group and/or a cyclic alkyl group, which are bonded by an ester bond or other bonds.

Abstract: An acid anhydride-introduced polymer and a polymer composition that have improved material properties including mechanical properties when used along with fillers. In the acid anhydride-introduced polymer, a side chain is grafted onto a polymer main chain, and an acid anhydride structure is introduced into the grafted side chain through an imide bond or an amide bond. The acid anhydride-introduced polymer may be obtained by reacting an amino group-containing polymer in which an alkyl chain having an amino group at a terminal is grafted onto a polymer main chain, and a compound having two acid anhydride structures. The polymer main, chain preferably is an olefin resin or a styrene thermoplastic elastomer. The polymer composition includes the acid anhydride-introduced polymer and fillers. The acid anhydride-introduced polymer content is preferably within the range of 0.1 to 20 mass %.

Abstract: In a storage device from which n bits of data are read at a time, data pieces whose logical bit positions are 0*8+k, 1*8+k, 2*8+k, 3*8+k, . . . , m*8+k (where k and m are natural numbers satisfying 0≦k≦7, 0 ≦m≦n/8−1) are stored in memory cells close to one another in a memory cell array, and the bit positions are shifted by a predetermined number of bits when data having a small number of significant bits is read from the memory cell array.

Abstract: A semiconductor integrated circuit is constructed with multiple stages of circuit blocks connected in vertical series between a first power supply line and a second power supply line. At least one of the circuit blocks is provided with a load unit connected in parallel therewith so that each circuit block consumes an approximately equal amount of current. This makes it possible to generate a stable intermediate voltage and suppress increases in current consumption and circuit area.

Abstract: An object of the present invention is to inhibit the influence of the reducing substances on the oxidative coloring reaction in biological components.A constitution of the present invention is that a compound having the free radical of the general formula (1) ##STR1## is previously added to the biological sample and then an incubation is carried out.An effect of the present invention is that the influence of the reducing substances on the oxidation reaction can be inhibited and, even when no reducing substance is present, there is no effect on the oxidation reaction.

Abstract: An oxidative chromogenic reagent free from interference by bilirubin used for the measurement of a biogenic substance by an enzymatic analysis, which comprises a compound or a salt thereof represented by the following formula wherein R.sup.1 and R.sup.2 independently represent a C.sub.3-4 -alkly group substituted with a sulfonic acid group or a C.sub.3-4 -hydroxyalkyl group substituted with a sulfonic acid group; and R.sup.3 and R.sup.4 independently represent a C.sub.1-4 -alkyl group, a C.sub.1-4 -alkoxy group, a substituted or non-substituted carbamoyl group, an acyl-substituted amino group, an aryl group, or a halogen atom. The reagent is stable and has excellent water solubility, and it enables high sensitive and accurate measurement because interference by bilirubin is substantially reduced or eliminated.

Abstract: Novel water-soluble methylenebis(dialkylaniline) derivatives of the following general formula and salts thereof are disclosed. They are useful as dye-forming substances in quantitative determination of peroxides in the copresence of peroxidase or the like. ##STR1## In the formula, R.sub.1 is hydrogen or a substituent selected from lower alkyl and C.sub.2-3 sulfoalkyl or hydroxysulfoalkyl; R.sub.2 is C.sub.2-3 sulfoalkyl or hydroxysulfoalkyl; and R.sub.3 is lower alkyl.
