Ruled surfaces have been studied by NAGATA IS], MARUYAMA [3, 41 and other authors from the point of view of classification. Especially on rational ruled surfaces we have known many facts, for example, an explicit condition for a divisor D to be ample, that for ID( to have an irreducible member and s
