摘要： An oxymethylene polymer resin shaped article having high flexural modulus, which is produced by molding an oxymethylene polymer resin, wherein the oxymethylene polymer resin is selected from the group consisting of an oxymethylene homopolymer resin, an oxymethylene copolymer resin and a mixture thereof. The oxymethylene copolymer resin comprises a copolymer of an oxymethylene monomer and a comonomer copolymerizable therewith, wherein the amount of the comonomer is extremely limited. The shaped article has the following characteristics: (1) a crystallinity of 72% or more; (2) an average crystallite size of 150 .ANG. or more; (3) 70% by volume or more of the whole volume of the shaped article being comprised of spherulites each having a diameter of 60 .mu.m or less; and (4) a thickness of 1 mm or more. The oxymethylene polymer resin shaped article of the present invention has an improved crystal structure, and exhibits excellent mechanical properties including especially high flexural modulus even when containing very little or no reinforcement. The oxymethylene polymer resin shaped article of the present invention can be advantageously used not only as a material for a sliding part and a precision part, such as a gear, a bearing and a lever, but also as a material for electric and electronic parts, such as a connector, a socket and a switch.

C.; 0.01 to 5.0 parts by weight of at least one bisamide compound of formula (1) ##STR1## and 0.0001 to 5.0 parts by weight of at least monoamide compound of formula (2) ##STR2## in which formulae (1) and (2) each of R.sup.1, R.sup.3 and R.sup.6 independently is an alkyl or an alkenyl, and R.sup.2 and R.sup.7 independently is an alkylene, an alkenylene, or --R.sup.4 --Ph--R.sup.5 -- (each of R.sup.4 and R.sup.5 independently is a single bond or a methylene, and Ph is a phenylene). The resin composition of the present invention has excellent mechanical strength retentivity during cooling-heating cycles. For example, not only occurrence of whitening, crazing or cracking but also lowering in impact resistance can be suppressed even after the resin composition experiences repeated cooling-heating cycles. Thus, the resin composition of the present invention can be advantageously used in various applications where repeated heating-cooling cycles are necessarily experienced. Also, disclosed is an insert molded article comprising the above-mentioned resin composition and a shaped part unified with the resin composition by insert molding, which article exhibits excellent cooling-heating cycle resistance with respect to the mechanical strength.

摘要： An imaging system that is capable of generating high resolution and high frame rate video includes of a beam splitter, two lenses, a high resolution-low frame rate camera, and a low resolution-high frame rate camera. The beam splitter reflects a part of an incident ray. The two lenses gather the ray reflected from the beam splitter and the ray penetrating the beam splitter, respectively. The low resolution-high frame rate camera is a sensor that takes an image of the ray gathered by one of the lenses at a low resolution and a high frame rate. The high resolution-low frame rate camera is a sensor that takes an image of the ray gathered by the other of the lenses at a high resolution and a low frame rate.
