The diagrams of state of three binary systems have been studied. One of these shows appearance of  intermediate phases of the type N and S_A, while in the other two diagrams, either N or S_A phase, as intermediate one, are observed. The explanation for their appearance is provided. The smectic C and smectic I phases of  HOAB remain restricted on its respective side and do not show any miscibility with smectic C phases of HBBA and HBOA.
