    • The present invention is to provide a method for taking a picture of a subject automatically in a digital camera including an image capturing unit, a CPU, a memory unit, a storage unit and a scanning program, comprising the steps of giving an image capturing instruction to the CPU for successively capturing images through the scanning program; causing the CPU to command the image capturing unit to successively capture at least a first image and a second image of a subject; storing the first image and the second image in the memory unit; causing the CPU to compare the first image and the second image by using the scanning program; generating an activating signal by the scanning program when contents of the first image and the second image are different; and causing the CPU to store the second image in the storage unit as the picture taken of the subject.

    • This invention discloses a method for preparing rubber compositions that exhibit unique combinations of properties that are desirable for tire tread applications for enhanced snow/ice and wet traction, low rolling resistance and increased treadwear performance in comparison with conventional silica compounds. Specifically, a high reactively silane coupling agent, such as a mercaptosilane, is used in combination with a silane coupling typically used for silica tread compounds such as bis(triethoxylsilylpropyl)disulfide to treat silica pellets in a hydrocarbon solvent at elevated temperatures. The treated silica is then blended with solution elastomer cement in a hydrocarbon solvent. The deposited reactive silanes partially react with the elastomer molecules forming a layer of polymer grafted on the silica surfaced. This structure significantly improves the silica retention during the steam stripping operation. Almost 100% (99+%) silica retention has been achieved by this invention. After solvent removal from steam stripping, the treated silica/elastomer mixer is dewatered and dried using conventional equipment such as shaker screens, expellers and expanders to form a well-dispersed silica masterbatch. This technique results in silica compounds with excellent silica dispersion and increased filler-polymer interaction, hence enhanced compound performance such as better physical properties, more desirable dynamic properties (low hysteresis at high temperatures and high hysteresis at low temperatures) and increased abrasion resistance.
    • 本发明公开了一种制备橡胶组合物的方法,其与常规的二氧化硅化合物相比,具有独特的性能组合,其性能优选用于轮胎胎面用于增强的雪/冰和湿牵引力,低滚动阻力和增加的胎面性能。 具体地,高反应性硅烷偶联剂如巯基硅烷与通常用于二氧化硅胎面胶料如二(三乙氧基硅烷基丙基)二硫化物的硅烷偶联剂一起使用,以在高温下在烃溶剂中处理二氧化硅颗粒。 然后将处理过的二氧化硅与溶剂弹性体粘结剂在烃溶剂中混合。 沉积的反应性硅烷与弹性体分子部分反应,弹性体分子形成接枝在二氧化硅上的聚合物层。 该结构显着改善了汽提操作期间的二氧化硅保留。 通过本发明实现了近100%(99 +%)二氧化硅保留。 在从蒸汽汽提除去溶剂后,将处理过的二氧化硅/弹性体混合器脱水并用常规设备如振动筛,推进器和膨胀机进行干燥以形成良好分散的二氧化硅母料。 这种技术导致具有优异二氧化硅分散性和增加的填料 - 聚合物相互作用的二氧化硅化合物,因此提高了化合物性能,例如更好的物理性能,更理想的动态性能(高温下的低滞后和低温下的高迟滞)和增加的耐磨性。
