We will give an elementary proof of the celebrated Massera Theorem for periodic differential equations. We will prove also that under some appropriate conditions, a second-order semilinear elliptic almost periodic equation has no almost periodic solution (in the sense of Bohr), but many almost automorphic and almost periodic (in the sense of Besicovitch) solutions in the envelope of the equation. We apply the results to study an almost periodically forced pen.
