    • A sealed alkaline storage battery with a long cycle life is disclosed, in which an inadequate adjustment between some of the electrode plates in a cell and the difference in the deterioration resulting from the difference in the heat dissipating abilities of the plates in the cell has been obviated. The storage battery comprises an electrode group configured by piling up a plurality of positive electrodes and a plurality of negative electrodes alternately with separators interposed therebetween, wherein the capacities of the respective negative electrodes are larger than those of the adjacent positive electrodes, except for the negative electrodes positioned at both ends of the electrode group. The capacities of the positive electrodes and the negative electrodes in the central part of the electrode group are larger than those of the positive electrodes and the negative electrodes located closer to both ends of the electrode group.

    • A developing device having a developing sleeve opposed to a photoreceptor, and a developer transport portion adjacent to the sleeve. The developer transport portion is divided into first and second portions by a partition, and the developer is circulated between the first and second portions. A fresh toner is supplied to the developer in the second portion to be transported to the first portion while being mixed, and thereafter is supplied to the sleeve along an axial direction of the sleeve in the first portion. The second portion is provided with a transport member by which the developer is transported at an upstream side of the second portion with respect to the developer transport direction in the second portion with a speed faster than the toner supply speed and the transport speed of the developer at a downstream side of the first portion with respect to the developer transport direction in the second portion.

    • An optical disk apparatus includes a photodetector divided into eight segments which receive the laser beam reflected from the optical disk and produce signals based on the laser beam sport thereon. In this apparatus, these eight segments are combined in several patterns for the recorded information reproduction, the tracking error detection, and the focus error detection, respectively. For the recorded information reproduction, eight segments are used as combined in three segment cells RC1, RC2, and RC3 which extend in a direction parallel to each other such that the segment cell RC1 is in center and is sandwitched by other segment cell RC2 and RC3. The segment cells RC1, RC2, and RC3 are located perpendicular to the recording track of the optical disk and produce three signals C, R, and L indicative of the laser beam intensity of the laser beam spot thereon, respectively. Thus obtained signals C is multiplied by a constant K and then added to the other signals R and L. By selecting suitable value as the constant K, the crosstalk component in the reproduced signal can be reduced.
    • 光盘装置包括被分成八个部分的光电检测器,其接收从光盘反射的激光束并基于其上的激光束运动产生信号。 在这种装置中,这八个段分别以记录信息再现,跟踪误差检测和聚焦误差检测的多种模式组合。 对于记录的信息再现,八个段被组合在三个分段单元RC1,RC2和RC3中,它们在彼此平行的方向上延伸,使得分段单元RC1处于中心并被其它分段单元RC2和RC3 。 分段单元RC1,RC2和RC3垂直于光盘的记录轨道定位,并分别产生表示激光束点的激光束强度的三个信号C,R和L。 这样获得的信号C乘以常数K,然后加到其他信号R和L.通过选择合适的值作为常数K,可以减少再现信号中的串扰分量。
