A transmitter includes a modulating and combining circuit to which signals are supplied and modulated into in-phase and quadrature-phase signals. A spreading code generating circuit generates spreading codes TP1 at a timing synchronized with the frame. The invention is also directed to methods of preparing the catalyst component slurry, the catalyst component solution and the catalyst compositions, to methods of controlling the properties of polymer products utilizing the catalyst compositions, and to polymers produced therefrom. The shifting unit is movably disposed around a center shifting axis to provide a compact structure.
