  • Patent number: 7530384
    Abstract: A twin roll casting machine that can reduce an amount of inert gas supplied. A duct is upwardly urged by cylinders to compress resilient sealing members respectively between a flange on a casting module and an upper flange on the duct and between a lower flange on the duct and a lower surface on a peripheral edge of an upper-end opening of an enclosure to maintain air-tightness of connections between the casting module and the duct and between the duct and the enclosure. A scrap box is moved upward by jacks to make a lower edge of a partition plate of an upper sealing member on the enclosure penetrate into the sealing material stored in a groove on the scrap box to maintain air-tightness of a connection between the scrap box and the enclosure.

  • Publication number: 20080288231
    Abstract: A cooperation verifying apparatus includes a storage unit and a processing unit. The processing unit simulates a software-based portion and a hardware-based portion in a target system, issues instruction signals from the software-based portion to the hardware-based portion in order during the simulation, stores a data of a progress state of the simulation of the software-based portion in the storage unit, stores the instruction signals in an order of reception as an input history in the storage unit and associates the input history with the progress state data.

  • Publication number: 20080123343
    Abstract: A light source device includes a solid light emitting element 1 having a reflection film on the back side, first and second reflection surfaces 2, 3 opposing each other in parallel and substantially perpendicular to a front surface of the solid light emitting element 1 and a third reflection surface 4 substantially perpendicular to the first and second reflection surfaces 2, 3 and opposing the front surface of the solid light emitting element 1. The third reflection surface 4 is inclined to the front surface of the solid light emitting element 1. The reflection film of the element 1, the first, second and third reflection surfaces 2, 3, 4 do constitute a closed polyhedron having an emission opening 5 smaller than a light emitting surface of the element 1. Light emitted from the element 1 is emitted to an outside through the emission opening 5.

  • Patent number: 7246651
    Abstract: A twin roll casting machine that can reduce an amount of inert gas to be fed for prevention of oxidization. The machine includes an enclosure enclosing a strip in a range from chilled rolls to pinch rolls, a first swing wall within the enclosure and having a tip end movable toward and away from a surface of the strip, a sealing roll rotatably supported by the tip end of the first swing wall, a second swing wall within the enclosure and having a tip end movable toward and away from the other surface of the strip, a sealing roll rotatably supported by the tip end of the second swing wall, sealing members between peripheral edges of the swing walls and an inner surface of the enclosure, and conduits for supplying inert gas into the enclosure. The respective swing walls are swung to bring the sealing rolls close to the strip to thereby suppress flow of the inert gas from a first space to a second space.

  • Patent number: 7172141
    Abstract: A lubricant mist sprayer is composed by spray headers, which have lubricant and gas supply pipes integrally fixed to each other by fixing members and which are spaced apart a required distance from and are arranged in parallel with surfaces of pinch rolls, and mist nozzles which are arranged at required intervals longitudinally of the spray headers for spraying lubricant mist m over the surfaces of the pinch rolls and which communicate with the lubricant and gas supply pipes so as to make the lubricant mist sprayer compact in size and facilitate arrangement of the lubricant mist sprayer in a narrow space of a roll chamber surrounding the pinch rolls in a metal strip continuous caster.

  • Patent number: 4654368
    Abstract: A tri-organotin silatrane derivative represented by the general formula (I) ##STR1## wherein the R.sup.1 groups are identical or different and each represents an alkyl, cycloalkyl, aryl or aralkyl group, R.sup.2, R.sup.3 and R.sup.4 are identical or different and each represents a hydrogen atom or a lower alkyl group, and m is a number of 2 or 3.The tri-organotin silatrane derivatives of the formula (I) are prepared by subjecting a 1-mercaptoalkylsilatrane and a tri-organotin hydroxide or bis(tri-organotin) oxide to a dehydration reaction, or reacting a 1-mercaptoalkylsilatrane derivative with a tri-organotin halide in the presence of a dehydrohalogenation agent, or subjecting a trialkoxysilane and a trialkanolamine to an ester-interchange reaction in the presence of an alkaline catalyst.The tri-organotin silatrane derivatives of the formula (I) are useful for an agricultural-horticultural pesticide, an industrial fungicide, an epidemic-preventing insecticide or an antifouling agent.
