review text: The author discusses with an application the isometric part and the coisometric part of a completely nonunitary contraction on a Hilbert space. [Probably, researchers who wish to know more general decomposition theorems should refer to \textit{W. Szymański}, Stud. Math. 50, 265-280 (1974; Zbl 0264.47036), \textit{M. Fujii}, \textit{Y. Kato}, Math. Jap., 21, 43-49 (1976; Zbl 0342.47019) and \textit{M. Fujii}, \textit{M. Kajiwara}, \textit{Y. Kato}, Math. Jap. 21, 117-120 (1976; Zbl 0343.47027), etc.].
