    • An electromagnetic vibrating diaphragm pump enabling improvement of working efficiency in fitting center plates to a diaphragm, reduction of production cost and stabilization of performance between products. The disk-like second plate includes the cruciform rising portion having the concave portions, and the second ring rib. The first ring rib is formed at the center of the surface of the disk-like first plate coming into contact with the diaphragm, and a fitting groove provided with convex portions to be press-fitted to the concave portions is formed by this first ring rib. The diaphragm has the protrusions for preventing the diaphragm from being pressed out on the periphery of the through-hole at its center, and the protrusions are engaged with the ring ribs from the circumference of the protrusion.

    • A reproduction speed conversion apparatus includes an audio decoding section; an audio reproduction speed conversion section; a video reproduction speed conversion section; and a video decoding section. The video reproduction speed conversion section determines whether reproduction speed conversion corresponding to a requested level is possible or not. When the reproduction speed conversion is determined to be possible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to the requested level. When the reproduction speed conversion corresponding to the requested level is determined to be impossible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to a prescribed level lower than the requested level, and outputs a second reproduction speed signal representing the prescribed level to the audio reproduction speed conversion section. The audio reproduction speed conversion section performs reproduction speed conversion corresponding to the prescribed level in response to the second reproduction speed signal.
