A complex speaker system includes a conical speaker including a recessed section at a surface thereof and configured to receive a sound-playback signal and reproduce sound and a distributed mode speaker installed in the recessed section of the conical speaker and configured to share the sound-playback signal input into the conical speaker. Also, a freely movable impedance control rod 26 is formed so as to interfere with characteristics of the wiring patterns 21a, 21b and 22a to 22c of the BPF 20 without touching them. The 2S canola protein is recovered as an isolate. \u201cP1\u201d and \u201cP2\u201d are independently a polymerizable group. The difference in length between the first and second optical paths and the refractive index of the first dielectric substance are set such that the first light beam is delayed by one bit with respect to the second light beam. The frame includes a separate support stand for supporting the blower housing on the top of the chamber.
