  • Publication number: 20170105363
    Abstract: A solar light type glass greenhouse includes a greenhouse unit. The greenhouse unit includes an under-eaves part including north, south, east and west lowersurface parts; and a ceiling part including a sloping roof on a north side, and south, east and west uppersurface parts. The sloping roof slopes by a sloping angle ? so that a south side is inclined upward when viewed from east. The sloping angle ? satisfies relations 15°<?<67°, and 63.6°-LAT???69.6°-LAT, where LAT is a latitude of an installation place. The sloping roof includes an eave extending to south beyond the south uppersurface part. A length of the eave is HS×sin(90°-?S)/sin(?S-?) or more, where ?S is a culmination altitude of the sun in the summer solstice, and HS is a sum of vertical lengths of the south lowersurface part and the south uppersurface part. The sloping roof includes a glass member having a heat reflective function.

  • Patent number: 7380416
    Abstract: The present invention provides a A metal conduit for molten glass and a vacuum degassing apparatus are disclosed, which are capable of coping with extension and contraction, and vibration. By disposing at least one convex portion 20 so to have a height of 4 mm or above in a radial direction and continuously extend in a peripheral direction, it is possible to absorb thermal expansion and contraction without changing the entire length of the metal conduit 10 and to suppress from the metal conduit 10 from vibrated even when molten glass 121 is conveyed by the metal conduit. By employing the metal conduit 10 stated earlier in an upstream conveying pipe 130A, an uprising pipe 122U, a vacuum degassing vessel 120, a downfalling pipe 122L, a downstream conveying pipe 130B or the like in a vacuum degassing apparatus 30, it is possible to cope with thermal expansion and contraction, and vibration caused when conveying molten glass 121.
