    • An ignition timing control apparatus can obtain high output torque without generating output torque loss, and avoid the deterioration of audibility due to successive knock occurrences. A cylinder specific ignition timing setting section includes a reference ignition timing control section, and a cylinder specific correction value setting section having correction values of the same number as that of engine cylinders. The reference ignition timing control section calculates reference ignition timing common to all the cylinders and uniformly controls the ignition timings of all the cylinders to a retard angle side to prevent the occurrence of successive knocks. The cylinder specific correction value setting section calculates cylinder specific correction values to compensate for variation in the cylinder specific optimal ignition timings, and sets the cylinder specific correction values for cylinders other than those whose knock frequency becomes equal to a predetermined value or more so as to advance their ignition timings.
    • 点火正时控制装置可以在不产生输出转矩损失的情况下获得高输出转矩,并且避免由于连续的敲击发生导致的可听性的恶化。 气缸专用点火正时设定部分包括参考点火正时控制部分和具有与发动机气缸数相同数量的校正值的气缸特定校正值设定部分。 参考点火正时控制部分计算所有气缸共用的基准点火时间,并将所有气缸的点火正时均匀地控制到延迟角侧,以防止连续敲击的发生。 气缸特定校正值设定部分计算气缸特定校正值,以补偿气缸特定的最佳点火正时的变化,并且设定除了爆震频率等于或等于预定值以上的气缸以外的气缸的专用校正值,以便 提高点火时间。

    • An image reading apparatus for reading images on films of different sizes and outputting read image data includes a film sensor for sensing the dimension of at least one side of each film and a control module for operating the apparatus so that at least one of the reading process and outputting process is performed under a parameter setting set beforehand in accordance with a signal from the film sensor. When a reading start instruction is issued from a control panel, a film width detecting circuit performs film sensing, thereby determining the film width of each film. Based on the film width, reading parameter values such as a pixel pitch, a density range, and a data transfer destination are selected from among those that are beforehand set through the control panel. Table update is made for a density linear conversion table according to the film width and an interpolation coefficient according to the pixel pitch. Each film is read through a halogen driving circuit and an actuator driving circuit, and the image data is output through an image data reading circuit.
    • 一种用于读取不同尺寸的胶片上的图像并输出读取图像数据的图像读取装置包括用于感测每个胶片的至少一个侧面的尺寸的胶片传感器和用于操作该装置的控制模块,使得读取过程中的至少一个 并且根据来自胶片传感器的信号预先设置的参数设置来执行输出处理。 当从控制面板发出读取开始指令时,胶片宽度检测电路执行胶片检测,从而确定每个胶片的胶片宽度。 基于胶片宽度,从通过控制面板预先设定的那些中选择读取参数值,例如像素间距,浓度范围和数据传送目的地。 根据胶片宽度和根据像素间距的内插系数,对密度线性转换表进行表格更新。 通过卤素驱动电路和致动器驱动电路读取每个胶片,并且通过图像数据读取电路输出图像数据。
