  A regularization for the baryon number consistent with the energy in the
Nambu-Jona-Lasinio model is introduced. The soliton solution is constructed
with the regularized baryon number constrained to unity. It is furthermore
demonstrated that this constraint prevents the soliton from collapsing when
scalar fields are allowed to be space dependent. In this scheme the scalar
fields actually vanish at the origin reflecting a partial restoration of chiral
symmetry. Also the influence of this constraint on some static properties of
baryons is discussed.
