    • Vinylphenol-type polymers are useful materials and are used in many fields such as photoresist, packaging material for IC, printed circuit board, lense, etc. When the polymers are used in an electronic field such as photoresist and packaging material for IC, it is desired to reduce metal concentration in the polymer in the order of ppb units. A simple and effective process for removing metals from vinylphenol-type polymers is disclosed. The process comprises passing an organic solvent solution of a vinylphenol-type polymer either through (a) a filter containing an ion exchange material and/or a chelate-forming material and generating a zeta (.zeta.) potential by a cationic charge modifying agent or through (b) (i) a filter containing an ion exchange material and/or a chelate-forming material and (ii) a filter generating a zeta (.zeta.) potential by a cationic charge modifying agent.
    • 乙烯基酚型聚合物是有用的材料,可用于许多领域,例如光致抗蚀剂,IC封装材料,印刷电路板,透镜等。当聚合物用于电子领域如光致抗蚀剂和用于IC的包装材料时,它是 希望以ppb单位的量级降低聚合物中的金属浓度。 公开了一种用于从乙烯基苯酚型聚合物中除去金属的简单且有效的方法。 该方法包括使乙烯基酚型聚合物的有机溶剂溶液通过(a)含有离子交换材料和/或螯合形成材料的过滤器,并通过阳离子电荷改性剂产生ζ(ζ)电位,或通过 (b)(i)含有离子交换材料和/或螯合形成材料的过滤器和(ii)通过阳离子电荷改性剂产生ζ(ζ)电位的过滤器。

    • A vibration isolating apparatus is disclosed which comprises an inner tube and an outer tube disposed in a parallel axis state to each other and an elastic member stretched therebetween, the elastic member being provided with a pair of liquid chambers disposed in the interior thereof at opposite sides through the inner tube. These liquid chambers communicate with each other through a restricted passage. The elastic member is provided with a pair of cavities on opposite outer sides of the inner tube. The cavities absorb relative displacement between the inner tube and the outer tube. When an amount of absorption becomes a predetermined amount, a compressing force is applied to the liquid chambers.

    • An exhaust gas recirculation system for an internal combustion engine employs an exhaust gas recirculation control valve in a passageway connecting the engine exhaust passage to the engine intake passage downstream from the throttle valve. The intake passage also provides a choke valve and a carburetor venturi section between the valves. An air conduit having an air control valve therein connects the intake passage between the throttle valve and the choke valve to the intake passage downstream from the throttle valve. Vacuum responsive actuators are provided for each of the control valves and they are operated by vacuum pressure regulated by a regulating valve, which is itself responsive to differential pressure between vacuum intensity in the intake passage upstream from said throttle valve and modified atmospheric pressure. The modified atmospheric pressure is obtained downstream of a restriction in the air conduit. Closing of the choke valve on a cold start of the engine causes high vacuum intake to the air conduit, reducing the exhaust gas recirculation through the exhaust gas recirculation control valve.
    • 用于内燃机的废气再循环系统在将发动机排气通道连接到节气门下游的发动机进气通道的通道中使用排气再循环控制阀。 进气通道还在阀之间提供阻流阀和化油器文丘里管部分。 具有空气控制阀的空气导管将节流阀和阻流阀之间的进气通道连接到节气门下游的进气通道。 为每个控制阀提供真空响应致动器,并且它们通过由调节阀调节的真空压力来操作,该调节阀本身对来自所述节流阀上游的进气通道中的真空强度与改进的大气压之间的压差有反应。 在空气管道中的限制下游获得改良的大气压力。 在发动机的冷启动时关闭阻风阀导致空气导管的高真空吸入,减少通过废气再循环控制阀的废气再循环。
