  A new family of solvable potentials related to the Schroedinger-Riccati
equation has been investigated. This one-dimensional potential family depends
on parameters and is restricted to the real interval. It is shown that this
potential class, which is a rather general class of solvable potentials related
to the hypergeometric functions, can be generalized to even wider classes of
solvable potentials. As a consequence the nonlinear Schroedinger-type equation
has been obtained.
