Encoded transmission and reception which reduces time side lobe are realized while suppressing increase of circuit scale. Transmission signals corresponding to a composite modulation code sequence composed from two or more modulation code sequences are outputted as transmission signals. A reception means demodulates reception signals stepwise by two or more demodulators. The demodulator can be thereby divided into two or more stages, and therefore with a circuit scale corresponding to the sum of the operation circuit numbers of two or more demodulators, time side lobe reduction effect can be obtained at a level equivalent to that obtainable with a circuit scale corresponding to the product of the operation circuit numbers of two or more demodulators.

The compound stores the light energy stably in the form of thermal energy, and releases the energy in need by the addition of a catalyst.

7-substituted quadricyclene-cyclodextrin clathrate compound and its preparation

PURPOSE:To produce the titled substance applicable to a solar system, etc. as an organic heat accumulator, by irradiating a 7-substituted norbornadiene with light. CONSTITUTION:The objective compound of formula II is obtained by irradiating the compound of formula I (R is OH, acyloxy or alkyloxy) at 0-100 deg.C using a high-pressure mercury lamp, a low-pressure mercury lamp, a xenon lamp, sun light, etc. as the light source. Since the compound of formula I is extremely susceptible to oxygen, the process comprising the degassing at the liquid nitrogen temperature and the heating of the system to normal temperature is repeated several times, and the system is sealed under reduced pressure. The production of polymer can be suppressed by this process. The irradiation of the compound of formula I can be carried out by diluting the compound properly with a light- stable solvent (e.g. n-hexane), and irradiating the solution. The isomerization reaction can be further promoted by the addition of a proper sensitizer (e.g. acetophenone).
