    摘要: Disclosed is a method of forming a ferrite film on particulate and/or fibrous substrate by adding an oxidizer solution and a ferrous ion solution to a deoxidized solution containing particulate and/or fibrous substrates to form a thin ferrite film on the particulate and/or fibrous substrates, wherein an addition amount of the ferrous ion solution is controlled such that an oxidation-reduction potential of the deoxidized solution keeps approximately a center point between the oxidation side and the reduction side, when a pH value of the dioxidized solution is adjusted to a constant value between pH 6 and 10.

    摘要: An element of a mixing apparatus having no moving parts. The element includes a hollow cylindrical body provided on an inner surface thereof with projecting plates for disturbing a flow of fluids within the hollow cylindrical body. The hollow cylindrical body is provided on one end thereof with a plurality of projections disposed at regular angular intervals. The hollow cylindrical body is provided on the other end thereof with a plurality of indents disposed at the same regular angular intervals as the projections. Each of the projections of one element is engageable with each of the indents of another element.
