    摘要: A process for producing a silicone polymer comprising a step of subjecting, to hydrolysis and polycondensation reaction, a silane compound mixture containing 35 to 100% by mol of a silane compound represented by the general formula (I): R′m(H)kSiX4−(m+k)  (I) (wherein X is a hydrolysable and polycondensable group, e.g., a halogen atom (e.g., chlorine or bromine) or —OR; R is an alkyl group of 1 to 4 carbon atoms or an alkyl carbonyl group of 1 to 4 carbon atoms; R′ is a non-reactive group, e.g., an alkyl group of 1 to 4 carbon atoms or an aryl group (e.g., a phenyl group); “k” is 1 or 2; “m” is 0 or 1; and “m+k” is 1 or 2), and further subjecting the resultant product to hydrosilylation reaction with a hydrosilylation agent.

    摘要: A digital carrier signal demodulation circuit is used in the carrier digital transmission system utilizing a 16-ary APK (Amplitude and Phase Keying) signal produced by the vector superposition of a second path signal consisting of a four-phase shift keying signal upon each phase of a first path signal consisting of a four-phase shift keying signal, the level of the second path signal being lower than that of the first path signal. The received 16-ary APK signal is detected with the reference carrier extracted from the received signal, regenerated to reproduce the base band pulses of the first path signal. The recovered base band pulses remodulate the reference carrier to produce the first path signal. The phases of the recovered first path signal and received signal are compared to phase lock a voltage controlled oscillator thereby producing the reference character.
