摘要： Injection moldable thermoplastic polyolefin resins containing from about 20 to about 40 wt % EPR dispersed in a continuous highly isotactic polypropylene having good paintability. Reactor prepared resins, or RTPO resins, containing highly isotactic polypropylene and from 20 to 30 wt % of an EPR component comprising from about 40 to about 55 wt % ethylene are particularly attractive for use in the production of automotive trim and fascia.

摘要： Binary indications are converted to an analog representation with significant reduction in ringing at the transitions between successive binary indications and in the period during each binary indication. The binary indications are disposed in a row-and-column matrix to provide a thermometer code. Each stage of the converter includes a decoder and latch arranged so the decoder inputs settle before the latch is set by the clock pulses. The stages are implemented in complementary CMOS. Complementary transistors are biased so one transistor of the pair is driven to the rail while the other transistor of the pair floats. A dummy CMOS transistor is used to balance the number of transistors in the decoder paths.
摘要翻译：二进制指示被转换为模拟表示，在连续的二进制指示之间的转换和每个二进制指示期间的周期中显着地减少振铃。二进制指示以行和列矩阵布置以提供温度计代码。转换器的每个级包括一个解码器和锁存器，所述解码器和锁存器布置成使得解码器输入在锁存器被时钟脉冲设置之前稳定。这些阶段在互补CMOS中实现。互补晶体管是偏置的，因此该对的一个晶体管被驱动到轨道，而另一个晶体管则浮动。虚拟CMOS晶体管用于平衡解码器路径中的晶体管数量。

摘要： In a gas phase olefin polymerization using a transition metal compound/aluminum alkyl catalyst system, polymerization can be terminated rapidly by injecting an amount of carbon oxide and then restarting efficiently by addition of an amount of aluminum alkyl.
摘要翻译：在使用过渡金属化合物/烷基铝催化剂体系的气相烯烃聚合中，通过注入一定量的碳氧化物可快速终止聚合，然后通过加入一定量的烷基铝来有效地重新开始聚合。
