Two binary systems UU Lyn (P = 0d.468) and GR Tau (P = 0d.430) are discussed on the basis of BV photoelectric observations and spectroscopic observations which were made between 1980 and 1981 at the Tokyo Astronomical Observatory. The component stars in both systems are found to be still inside their Roche lobes but very close to them.
