    • Disclosed is a process for preparing water absorbing, cross-linked acrylate resins by aqueous polymerization of (A) acrylic acid neutralized 70 to 100 mole percent for example with ammonia, and/or caustic alkali and/or an amine; with (B) acrylamide in a mole ratio of 70 to 100 mole percent (A) to 30:0 mole percent (B); and (C) a water miscible or a water soluble polyvinyl monomer in an amount of 0.001 to 0.3 weight percent based on the total weight of (A) and (B). In accordance with one embodiment of the invention, the concentration of monomers (A) plus (B) should be at least 70 percent by weight of the polymerization mixture of (A) plus (B) plus (C) to achieve a substantially dry polymer (less than 15 weight percent water) when polymerization is completed by utilizing the exothermic heat of polymerization and cross-linking to drive off water without the need for additional heating to obtain a dry solid. The addition of polystyrene and/or methylcellulose substantially increases the water absorbing capacity of these polymers.
    • 公开了一种通过(A)丙烯酸的水性聚合制备吸水交联丙烯酸酯树脂的方法,例如用氨和/或苛性碱和/或胺中和的70-100摩尔% (B)丙烯酰胺,摩尔比为70-100摩尔%(A)至30:0摩尔%(B); 和(C)基于(A)和(B)的总重量,0.001至0.3重量%的水混溶性或水溶性聚乙烯基单体。 根据本发明的一个实施方案,单体(A)加(B)的浓度应为(A)加(B)加(C)的聚合混合物的至少70重量%,以实现基本上干燥的聚合物 (小于15重量%的水),当聚合完成时,通过利用聚合的放热和交联以驱除水而不需要额外的加热以获得干燥的固体。 聚苯乙烯和/或甲基纤维素的加入显着增加了这些聚合物的吸水能力。

    • A receiving apparatus is provided for receiving a serial signal composed of a sequence of signals transmitted through a transmission medium. In the receiving apparatus, a receiving circuit receives as a received signal a serial signal, which is a sequence of signals including at least one of a synchronizing signal and an information signal, and which includes a plurality of signals being the same as each other and being apart from each other by a predetermined time interval. Then, a delaying circuit generates a delayed signal by delaying the received signal by the predetermined time interval, and a multiplying circuit generates a multiplied signal by multiplying the received signal by the delayed signal. Finally, a detecting circuit detects at least one of the synchronizing signal and the information signal, based on the multiplied signal.
