Abstract: A fuel delivery control apparatus for use with an internal combustion engine including an exhaust system having a catalytic converter containing catalysts operable at a temperature for purifying exhaust gases discharged through the exhaust system. A fuelcut control is performed to interrupt fuel delivery to the engine during engine deceleration. The fuelcut control is inhibited when the catalyst temperature exceeds a predetermined value.

Abstract: A resin composition comprises an EVOH (A) and a thermoplastic polymer (B) having at least one functional group selected from the group consisting of boronic acid group, borinic acid group and boron-containing groups convertible into boronic acid group or borinic acid group in the presence of water. The composition may further comprise a thermoplastic polymer (C) other than (A) or (B). The resin compositions thus obtained have good compatibility and give molded products having superior transparency and good mechanical properties.

Abstract: A vinyl alcohol copolymer having a terminal amino group and comprising 1-90 mol % of vinyl alcohol units and 10-90 mol % vinyl monomers selected from the group consisting of olefins, acrylamides, methacrylamides, vinyl ethers, nitriles, vinyl halides, and vinylidene halides, said copolymer having at least one terminal amino group is useful for preparing resin compositions having good gas barrier properties.

Abstract: Provided are polyvinyl ester macromonomers (A) having excellent polymerizability and highly controlled composition, structure and distribution of polymerization degree.Also provided are polyvinyl alcohol macromonomers (B) obtained by solvolysis of the above polyvinyl ester macromonomers (A) and having excellent polymerizability and highly controlled composition, structure and distribution of polymerization degree.Further provided are polymers (C) obtained by polymerization of the above polyvinyl ester macromonomers (A) and containing units from polyvinyl ester macromonomers having highly controlled composition, structure and distribution of polymerization degree. These polymers (C) are useful as compatibility improving agents, surface improving agents and like agents.

Abstract: An acetanilide derivative of the following formula (I) and a herbicide containing one or more of the acetanilide derivative as the active ingredient are described. ##STR1## In the formula, R.sup.1 is a lower alkyl group; R.sup.2 is a fluorine-substituted lower alkyl group; A is ##STR2## B is an optionally substituted pyrazolyl group, an optionally substituted alkoxy group or a hydrogen atom.The acetanilide derivative and the herbicide have a selective weed killing activity to gramiveous weeds.

Abstract: A tri- or tetra-substituted phenoxy alkylene- or alkenylene-anilide compound represented by the following formula ##STR1## wherein R, R.sup.1, R.sup.2, X, Y, l, m and n are as defined in claim 1; a process for producing the aforesaid anilide compound; and its use as a herbicidal composition.

Abstract: A herbicidal compound having the following formula ##STR1## wherein n is 0 or 1; a herbicidal composition comprising said compound as an active ingredient; a process for producing said composition; and a herbicidal method employing said compound.

Abstract: A herbicidal composition comprising a herbicidal amount of a mixture of(a) at least one S-.alpha.,.alpha.-dimethylbenzyl-N-alkylenimine carbothiolate of the formula ##STR1## wherein R represents a lower alkyl group, m is 0, 1 or 2, n is 4, 5 or 6, and the chain of n --CH.sub.2 -- linkages may contain one oxygen atom, and(b) at least one compound selected from the group consisting of N-[p-(p-chlorobenzyloxy)phenyl]-3,4,5,6-tetrahydrophthalimide, 1,3-dimethyl-4-(2,4-dichlorobenzoyl)-5-(p-tolylsulfonyloxy)pyrazole, 3,4-dichloropropionanilide, and 1-(2-phenylpropyl)-3-(4-tolyl)urea, and a method for controlling weeds, which comprises applying 1 to 2,000 g/10 ares of the aforesaid composition to the locus where the weeds are growing or will grow. The composition is especially useful in rice cultivation for controlling weeds of Family Gramineae (e.g., barnyard grass) and broad-leaved weeds without toxocity to rice.
