    Abstract: The invention relates to a photocatalytic body having a good photocatalytic function characterized by using an amorphous titanium peroxide sol, and a method for making the same. A photocatalyst such as titanium oxide in the form of powder or a sol and an amorphous titanium peroxide sol are mixed in different mixing rations depending on the purpose in use and the resultant mixture is coated onto a substrate such as an organic polymer resin, dried-solidifed and/or baked to support and fixed the photocatalyst on the substrate to make a photocatalytic body. Alternatively, a first layer consisting of an amorphous titanium peroxide sol on a substrate, and a second layer made of a photocatalyst is formed on the first layer to make a photocatalytic body. According to the invention, the photocatalyst can be supported and fixed on the substrate without lowering the photocatalytic function of the photocatalyst to obtain a photocatalytic body which is usable over a long time.

    Abstract: An in-line data communication system includes a bidirectional communication cable for connecting at least two terminal stations. A signal level compensation circuit is connected to the bidirectional communication cable for compensating for signal attenuation in the bidirectional communication cable. The signal level compensation circuit includes first and second amplifying circuits connected to each other in a parallel fashion. When a data signal is transmitted in one direction in the bidirectional communication cable, the first amplifying circuit is enabled and the second amplifying circuit is disabled. When the data signal is transmitted in the opposing direction, the first amplifying circuit is disabled and the second amplifying circuit is enabled.
