    • It is an object of the present invention to provide an antifouling coating resin dispersion which has excellent storage stability and water resistance in sea water, can exhibit an antifouling effect over a long period of time, and has self-polishing properties with excellent adhesiveness. A method for producing the antifouling coating resin dispersion according to the present invention includes the steps of: producing a polymer (A) containing a divalent metal; and dispersing the polymer (A) in a dispersion medium containing water or a mixture of water and an organic solvent. The polymer (A) containing a divalent metal is obtained by subjecting 1 to 40% by mass of a divalent-metal-containing ethylenically unsaturated monomer (a1), 0 to 8% by mass of a carboxyl-group-containing ethylenically unsaturated monomer (a2), 0 to 40% by mass of a hydroxyl-group-containing ethylenically unsaturated monomer (a3), and 99 to 22% by mass of another ethylenically unsaturated monomer (a4) to solution polymerization in a multi-stage which includes two or more stages.

    • A piezoelectric ceramic transformer includes a high impedance portion having internal electrode layers which are opposite each other in a thickness direction in a radial central portion of a piezoelectric ceramic disc; an annular insulating portion disposed externally of the high impedance portion and having no electrode; and a low impedance portion disposed externally of the annular insulating portion and having annular internal electrode layers which are opposite each other in a thickness direction, the internal electrode layers of the high impedance portion being exposed on the side end face of the piezoelectric ceramic disc at respective ends thereof without being in contact with the annular internal electrode layer of the low impedance portion and being alternately connected on the side end face with external electrodes, each of which is connected with an electric terminal, and the internal electrode layers of the low impedance portion being exposed on the side end face of the piezoelectric ceramic disc at respective ends thereof and being alternately connected on the side end face with external electrodes, each of which is connected with an electric terminal. The transformer is operable in a high frequency band and can be used for an onboard power supply.
