Previous ideas of the authors [J. Differ. Equations 50, 318--329 (1983; Zbl 0526.35030)] are used to extend some existence results of \textit{H. Berestycki} and \textit{D. G. de Figueiredo} [Commun. Partial Differ. Equations 6, 91--120 (1981; Zbl 0468.35043)] to certain problems on an unbounded domain.
