Abstract: PURPOSE:To attain each function of an amplification of a signal of a TTL level, a polarity inversion, a level shift, and a drive by combining three pieces of analog switch elements of a positive polarity use analog switch element, a negative polarity use analog switch element, and a polarity selecting analog switch element. CONSTITUTION:A signal (a) of a TTL level is inputted to each control input terminal of a positive polarity use analog switch element 21 and a negative polarity use analog switch element 22. As a result, in accordance with its control input signal (a), two constant-voltage sources are selected, and an amplifying function, an inversion or non-inversion function of the polarity, and a level shift function are attained. Also, to two input terminals 23A, 23B of a polarity selecting analog switch element 23, each output signal of the positive polarity use analog switch element 21 and the negative polarity use analog switch element 22 is inputted. As a result, by selecting its polarity signal, the polarity inversion function is attained.

IPC: C08G65/02
Filed: 1984-11-13
Abstract: PURPOSE:To purify a crude polyether obtained by using a heteropolyacid as a polymerization catalyst in good efficiency, by adding a 15 C or lower hydrocarbon to the polyether to separate the heteropolyacid by precipitation and distilling the contained tetrahydrofuran. CONSTITUTION:An alkylene oxide, tetrahydrofuran (THF) or the like is polymerized by using a heteropolyacid (e.g., phosphomolybdic acid) as a polymerization catalyst to produce a mixture of THF with a polyether having polyoxytetramethylene groups. To this mixture a 15 C or lower (halo) hydrocarbon solvent of a b.p. higher than that of THF and does not form an azeotrope with THF (e.g., octane) is added to separate the heteropolyacid by precipitation. The THF is recovered by distillation and a liquid containing a polyether is separated from the major part of the solvent. The residual solvent is removed by distillation to obtain a purified polyether.
