An ultrasonic color Doppler diagnostic apparatus for displaying at least two successive frames of original images of the two-dimensional images obtained for each ultrasonic interframe time, to find and display a natural interpolated image. The apparatus includes a shape parameter calculating unit which calculates the shape parameters characterizing the shape of a blood flow region on the original images and, a shape parameter interpolating unit which calculates the shape parameters interpolated at a designated timing designated in the interframe time from the shape parameters, the interframe time. In addition and the designated timing, an image converting unit is provided which converts the image of at least one frame of the original image in the plurality of original images in accordance with the shape parameters at a designated timing found by the shape parameter interpolating means to obtain the interpolated image. Further, displaying means is included which displays a moving image comprised of the interpolated images inserted between the original images and moving images of only the interpolated images.

A cylindrical magnetic domain element is disclosed which utilizes a cylindrical magnetic domain (a magnetic bubble) produced by the application of a bias magnetic field to a magnetic sheet of orthoferrite, garnet or the like. Propagation patterns for the cylindrical magnetic domain are composed of a plurality of sets formed on one side of the magnetic sheet and have a multilayer construction with a non-magnetic film of SiO.sub.2 or the like between the layers. This multilayer construction allows for the formation of a propagation pattern having a relatively narrow pattern gap. Further, the propagation pattern is disclosed as having uniaxial magnetic anisotropy, which facilitates the magnetic bubble propagation and ensures retaining of the magnetic bubble.
