摘要： The present invention relates to 1,3,5-tricyano-2,4,6-tris(vinyl)benzene derivatives and method for preparing the same. The 1,3,5-tricyano-2,4,6-tris(vinyl)benzene derivatives can be prepared by refluxing 1,3,5-tricyanomesitylene with N-formylamine dimethylacetal or substituted benzaldehyde, or by the Wittig reaction of 1,3,5-tricyano-2,4,6-tris[(diethoxyphosphoryl)methyl]benzene with substituted benzaldehyde. The 1,3,5-tricyano-2,4,6-tris(vinyl)benzene derivatives exhibit large first hyperpolarizability in solution and significant second harmonic generation (SHG) in the powder state, and are useful as optical devices such as electro-optic modulators, optical switch, or the like for treating optical signal in optical communication industry.

摘要： The present invention relates to a connection state setting method of a dual tuner and an apparatus. In accordance with an embodiment of the present invention, the method of setting a tuner connection state of n satellites in a digital broadcast receiver having the plurality of tuners, n being a natural number, that are connected to one or more antennas includes setting the tuner connection state for each satellite by using a satellite signal inputted from each satellite, which has information on one antenna, and setting the tuner connection state between the satellites by using a connection state set for each satellite and the satellite signal inputted from each satellite. Accordingly, with the present invention, the digital broadcast receiver having two tuners can automatically set the connection state of satellite lines of each tuner.
