    • An image forming apparatus can reduce a system return time by reducing a time required for initialization of peripheral control integrated circuits according to a control program and achieves a low-power consumption so as to improve convenience for a user. A CPU performs a control of the image forming apparatus. A control bus for address and data is controlled by the CPU. A memory is connected to the control bus and is configured to store a control program of the CPU. A reset IC initializes the CPU when a power is turned on. A peripheral control ASIC controls each part of the image forming apparatus in accordance with an instruction of the CPU. An exclusive control bus is connected to the peripheral control ASIC. An operation of the exclusive control bus is started according to an input from the reset IC so as to perform an initializing process of the peripheral control ASIC.
    • 图像形成装置可以通过减少根据控制程序的外围控制集成电路的初始化所需的时间来减少系统返回时间,并且实现低功耗,从而提高用户的便利性。 CPU执行图像形成装置的控制。 用于地址和数据的控制总线由CPU控制。 存储器连接到控制总线,并被配置为存储CPU的控制程序。 当电源打开时,复位IC初始化CPU。 外围控制ASIC根据CPU的指令控制图像形成装置的每个部分。 专用控制总线连接到外围控制ASIC。 根据来自复位IC的输入开始专用控制总线的动作,以进行外围控制ASIC的初始化处理。

    • A 4-wheel drive vehicle has a driving force control method in which a portion of a driving force for front wheels is distributed to rear wheels through clutches. In a 4-wheel drive state in which a driving force T.sub.p is distributed to rear wheels, for example, if the vehicle is turned leftwards to generate a difference W.sub.R -W.sub.L between left and right rear wheel speeds, it is ensured that a driving force T.sub.R distributed to the right rear wheel, which is an outer wheel during turning of the vehicle, is larger than a driving force T.sub.L distributed to the left rear wheel, which is an inner wheel during turning of the vehicle, thereby providing an enhancement in turning performance. As the difference W.sub.R -W.sub.L between the left and right rear wheel speeds is increased as a result of decreasing of the turning radius of the vehicle, the driving force T.sub.P (=T.sub.L +T.sub.R) distributed to the rear wheels is decreased to avoid an increase in travel resistance. Thus, it is possible to prevent the occurrence of problems such as a deterioration of specific fuel consumption, an abnormal sound generated in a drive system and an increase in the load of the drive system due to an increase in travel resistance during turning of the vehicle.
    • 四轮驱动车辆具有驱动力控制方法,其中前轮的驱动力的一部分通过离合器分配到后轮。 在驱动力Tp分配给后轮的四轮驱动状态下,例如,如果车辆向左转动以在左后轮速度之间产生差WR-WL,则确保驱动力 分配到作为车辆转动时的外轮的右后轮的TR大于分配给作为车辆转向期间的内轮的左后轮的驱动力TL,从而提供转向增强 性能。 由于左右后轮速度之间的差WR-WL由于车辆的转弯半径的减小而增加,所以分配给后轮的驱动力TP(= TL + TR)减小,以避免增加 在旅行阻力。 因此,能够防止由于在车辆转动期间的行驶阻力的增加而导致比燃料消耗的劣化,驱动系统中产生的异常声音和驱动系统的负载的增加等问题的发生 。
