  • Patent number: 7807267
    Abstract: The present invention relates to a method for modifying a porous film mainly having Si—O bonds wherein a thermal treatment is conducted without using a metal catalyst by bringing an organic silicon compound into contact with the porous film. The organic silicon compound includes one or more Si—X—Si bond unit (wherein X represents O, NR, CnH2n, or C6H4; R represents CmH2m+1 or C6H5; m is an integer between 1 and 6; and n is 1 or 2) and two or more Si-A bond units (wherein A represents H, OH, OCeH2e+1 or a halogen atom and can be the same or different within a single molecule; and e is an integer between 1 and 6). Since the porous film obtained by this method is excellent in the hydrophobic property and the mechanical strength, it can be used as an optically functional material or an electronically functional material. The porous film is especially useful as a semiconductor material, and can be preferably used as an interlayer insulating film in a semiconductor device.

    Abstract: A conveyor belt with a guide includes: a flat belt; and a guide projecting from a surface of the flat belt on a side of a pulley along a longitudinal direction; the flat belt and the guide being integrally molded with an elastic material. Thus, the guide cannot be detached from the flat belt, thus achieving a high traveling stability and conveying performance for a long time. It is preferable that a core wire or cloth should be embedded in the flat belt, and further, that a vertical groove should be formed along a longitudinal direction at a bottom of the guide.
