    • An efficient process for producing methyl methacrylate which can give a high methacrylic acid conversion even when the mole ratio of methanol to methacrylic acid is small, said process comprises using an apparatus comprising a reaction zone having plural reaction sections connected in series and containing a strongly acidic ion-exchange resin and a distillation zone, feeding methacrylic acid to the first reaction section, feeding methanol to one or more reaction sections after the first reaction section, sending the reaction mixture formed in each reaction section to a reaction section just thereafter, feeding the vapor generated in each reaction section to a reaction section just therebefore, effecting simultaneously reaction and distillation in each reaction section of the reaction zone and distilling the vapor generated in the first reaction section in the distillation zone to separate methyl methacrylate.
    • 即使当甲醇与甲基丙烯酸的摩尔比小时甲基丙烯酸转化率高的甲基丙烯酸甲酯的生产方法也是一个有效的方法,所述方法包括使用包括反应区的装置,该反应区具有串联连接并且含有强酸性 离子交换树脂和蒸馏区,将甲基丙烯酸输送到第一反应段,在第一反应段之后将甲醇进料至一个或多个反应段,将每个反应段中形成的反应混合物送入反应段, 在每个反应部分中产生的蒸汽到达之前的反应部分,同时在反应区的每个反应段中同时进行反应和蒸馏,并蒸馏出蒸馏区中在第一反应段中产生的蒸气以分离甲基丙烯酸甲酯。

    • An automatic exposure (AE) sensor includes a line-selecting circuit for line selection between horizontal lines and vertical lines, in addition to components of a typical AE sensor. The line-selecting circuit temporally filters a SYNC pulse for notifying a subsequent circuit about a pulse timing of an imaging signal to select a line to be read out and to cause the subsequent circuit to change an active pixel region. The number of selected lines is determined by an external input. The active pixel region is reduced when the AE sensor is incorporated in a device having a low performance CPU, thereby reducing load on the CPU. The active pixel region is increased when the AE sensor is incorporated in a device having a high performance CPU, thereby effectively using the CPU performance to achieve higher density control.
    • 自动曝光(AE)传感器除了典型的AE传感器的部件之外还包括用于水平线和垂直线之间的线选择的线选择电路。 线路选择电路对SYNC脉冲进行时间滤波,以通知后续电路关于成像信号的脉冲定时,以选择要读出的行,并使随后的电路改变有源像素区域。 所选行的数量由外部输入决定。 当AE传感器被并入具有低性能CPU的设备中时,有源像素区域减小,从而减少CPU上的负载。 当AE传感器被并入具有高性能CPU的设备中时,有源像素区域增加,从而有效地利用CPU性能来实现更高密度的控制。
