  • Patent number: 8372346
    Abstract: In an apparatus for producing trichlorosilane, an internal space of a reaction chamber is partitioned in a radial direction by first walls running along a circumferential direction, and is partitioned into multiple spaces by second walls which extend in a direction crossing the circumferential direction. Upper portions or lower portions of the first walls and the second walls are formed with a communicating portion which circulates a raw material gas to be introduced, toward a central portion of a reaction chamber while the raw material gas goes through the small spaces sequentially and is turned up and down, heaters are installed in the small spaces, one of small spaces on both sides of the second walls is used as a small space for a upward flow passage, and the other is used as a small space for a downward flow passage, and the small spaces communicate with each other via the communication portion of the second walls.

  • Publication number: 20130017941
    Abstract: A swing roll 36 is arranged over a gluing roll 14 and is configured to be movable in the direction of the arrow, so that the number of flute tips of a single faced corrugated cardboard k that are to be concurrently in contact with the gluing roll 14 at a nip N between the gluing roll 14 and a pressure roll 20 can be adjusted, and an amount of glue to be applied to each flute tip m of the single faced corrugated cardboard k can be optimized. In addition, since the pressure roll 20 is arranged on the same horizontal level as the gluing roll 14, influence of a bend caused by the weight of the pressure roll 20 can be avoided and the glue can be applied evenly in the width direction. The single faced corrugated cardboard k is wrapped around the pressure roll 20 at the exit of a nip N to allow a splash s of glue to return to a glue bath 12. Additionally, this configuration makes the single faced corrugated board to leave the surface of the gluing roll at a constant point d.
