Long mold-life time is great important for roll-to-roll process in UV nanoimprint. We investigated the cause of the decay of the releasing performance by various surface characterization methods. We optimized the coating condition of the releasing agent, and we have achieved the elongation of the mold life-time.
The comparison of visual magnitudes of stars compiled in old materials is expected to yield informations about their long-term magnitude variations. In seven old catalogues whose philological studies were finished, the sampled stars amount to 2124 except for stars that we could not identify, double stars and known variables.
