    • Simultaneous interpretation apparatus using matrix circuits whereby, even when an additional original language is used other than the specified original languages for the apparatus, simultaneous interpretation of that additional original language into the specified original languages is accomplished with ease and without hindrance. The present invention is particularly adapted to the interpretation of four specified original languages, for example Japanese, English, French and Spanish, and is particularly useful when an additional original language is used, such as Chinese for example. The matrix circuitry of the present invention enables translation of the additional original language to proceed even though the apparatus is primarily adapted for use in interpreting and translating the four specified original languages. Without this matrix circuitry the apparatus could not adapt to the additional original language since certain translators would not be alerted to perform their translating duties.
    • 使用矩阵电路的同声传译装置,由此即使使用除设备的指定原始语言之外的附加原始语言,也可以容易且无障碍地实现将该附加原始语言同时解释为指定的原始语言。 本发明特别适用于四种特定的原始语言的解释,例如日语,英语,法语和西班牙语,并且在使用其他原始语言(例如中文)时特别有用。 即使该装置主要适用于解释和翻译四个指定的原始语言,本发明的矩阵电路也能够使附加原始语言的翻译继续进行。 没有这种矩阵电路,该装置不能适应附加的原始语言,因为某些翻译器将不会被警告以执行其翻译任务。

    • A thermoplastic resin having an excellent thermal stability and a high heat resistance is prepared by initiating polymerization of 65-85 parts by weight of a monomer mixture (A) consisting of 50-85% by weight of .alpha.-methylstyrene, 3-20% by weight of methyl methacrylate, 2-20% by weight of acrylonitrile, and 0-25% by weight of an aromatic alkenyl compound other than .alpha.-methylstyrene, continuously or intermittently adding, on the way of the polymerization, 2-15 parts by weight of a monomer (B) consisting of acrylonitrile or a mixture thereof with an aromatic alkenyl compound other than .alpha.-methylstyrene to the polymerization system while continuing the polymerization, further adding to the polymerization system 5-25 parts by weight of a monomer (C) consisting of an aromatic alkenyl compound other than .alpha.-methylstyrene, or a mixture thereof with acrylonitrile, and continuing the polymerization to complete the polymerization, the total amount of monomers (A), (B), and (C) being 100 parts by weight. Further, a thermoplastic resin composition having an excellent thermal stability, a high heat resistance and a high impact strength is prepared by mixing the thermoplastic resin thus obtained with a graft copolymer obtained by grafting 60-30 parts by weight of a monomer mixture consisting of 65-80% by weight of an aromatic alkenyl compound and 35-20% by weight of acrylonitrile on 40-70 parts by weight of a diene rubbery polymer in such a proportion that the composition contains 10-30% by weight of the rubbery polymer.
