    • A process for producing raw rubber from a deproteinized natural rubber is disclosed, which comprises coagulating rubber particles in the deproteinized natural rubber latex by: (1) adding a nonionic surfactant having a cloud point of from 20.degree. to 100.degree. C. and a molecular weight of 300 or more to the deproteinized natural rubber latex and heating the latex to a temperature not lower than the cloud point of the nonionic surfactant; or (2) adding a coagulation assistant selected from the group consisting of: (a) an anionic surfactant, (b) an amphoteric surfactant, (c) a nonionic surfactant, (d) a nonionic or amphoteric oligomer or polymer, and (e) an anionic oligomer or polymer, to the deproteinized natural rubber latex; and then recovering the coagulated rubber particles. According to the process of the present invention, raw rubber containing substantially no metal ion can be produced with a high efficiency.
    • 公开了一种从脱蛋白天然橡胶生产生橡胶的方法,其包括:通过以下步骤将脱蛋白天然橡胶胶乳中的橡胶颗粒凝结:(1)加入浊点为20至100℃的非离子表面活性剂和分子 重量为300以上的脱蛋白天然橡胶胶乳,并将胶乳加热至不低于非离子表面活性剂的浊点的温度; 或(2)加入选自以下的凝血助剂:(a)阴离子表面活性剂,(b)两性表面活性剂,(c)非离子表面活性剂,(d)非离子或两性低聚物或聚合物,和 )阴离子低聚物或聚合物; 然后回收凝固的橡胶颗粒。 根据本发明的方法,可以高效率地生产基本上不含金属离子的生橡胶。

    • A wireless terminal device performs first, second, and third scans in sequence to detect wireless access points; stores base station information on the detected wireless access points in a storing unit; sets a disappearance flag in base station information that correspond to a wireless access point that was detected in the first scan and not in the second scan; sets a reappearance flag in base station information that correspond to a wireless access point that was not detected in the second scan and was detected in the third scan; identifies a wireless base station corresponding to base station information in which the disappearance flag and the reappearance flag are set; and displays information on the wireless base station identified on a display unit.
