    • A sub-delay element has the same configuration as that of a main delay element, and applies a delay τ that corresponds to a bias voltage to a selected clock signal output from a first selector. A phase detectorgenerates a phase detection signal that corresponds to the phase difference between a selected clock signal that has propagated through the sub-delay element and a selected clock signal that has propagated through a bypass path. A counter performs a count operation according to the phase detection signal. A D/A converter supplies a bias voltage that corresponds to the count value of the counter to the main delay element and the sub-delay element. An initialization unit instructs a DLL circuit to actually operate, and sets the reference voltage to be supplied to the D/A converter based upon the fluctuation in the count value of the counter.
    • 子延迟元件具有与主延迟元件相同的配置,并将对应于偏置电压的延迟τ施加到从第一选择器输出的所选择的时钟信号。 相位检测器产生相位检测信号,该相位检测信号对应于已经通过辅助延迟元件传播的所选择的时钟信号与已经通过旁路路径传播的选定时钟信号之间的相位差。 计数器根据相位检测信号执行计数操作。 D / A转换器将对应于计数器的计数值的偏置电压提供给主延迟元件和次延迟元件。 初始化单元指示DLL电路实际操作,并且基于计数器的计数值的波动来设置要提供给D / A转换器的参考电压。

    • A power supply device supplies power to an image forming apparatus. The image forming apparatus includes a load and a control unit. The load requires power, and is controlled by the control unit. The power supply includes a capacitor and a power-supply unit. The capacitor is charged by an external power source, and dischargably stores therein power. The power-supply unit provides power supply from the capacitor to the load and the control unit before voltage of the external power source drops below a threshold level where malfunction of the image forming apparatus occurs. After the voltage recovers to the threshold level, the power-supply unit stops the power supply from the capacitor.
    • 电源装置向图像形成装置供电。 图像形成装置包括负载和控制单元。 负载需要电源,由控制单元控制。 电源包括电容器和电源单元。 电容器由外部电源充电,并且可放电地存储电力。 电源单元在外部电源的电压下降到低于图像形成装置发生故障的阈值水平之前,从电容器向负载和控制单元提供电力供应。 电压恢复到阈值电平后,电源单元停止电容器的电源。

    • An access point performing a communication with a wireless terminal performing a communication according to a predetermined wireless communication specification acquires a connection parameter required for a communication based on the predetermined wireless communication specification from a connection parameter server which can be connected thereto through a network. The access point sets an access point connection parameter in the access point itself. The wireless terminal acquires a wireless terminal connection parameter by using a communication method not requiring setting from the access point in advance and sets it in the wireless terminal itself. This completes the setting for performing a communication based on the predetermined wireless communication specification and it is possible to start a communication based on the predetermined wireless communication specification between the wireless and access point. Thus, it is possible to set a connection parameter for a wireless communication in the wireless terminal and access point without requiring a complicated setting work by a user.
    • 根据预定的无线通信规范执行通信的无线终端进行通信的接入点从可以通过网络与其连接的连接参数服务器基于预定的无线通信规范获取通信所需的连接参数。 接入点本身设置接入点连接参数。 无线终端通过使用不需要从接入点进行设定的通信方式来取得无线终端连接参数,并将其设置在无线终端本身。 这完成了基于预定无线通信规范进行通信的设置,并且可以基于无线和接入点之间的预定无线通信规范来开始通信。 因此,可以在无线终端和接入点中设置用于无线通信的连接参数,而不需要用户进行复杂的设置工作。

    • When an operation mode of an image forming apparatus returns from an energy-saving mode to a regular operation mode, a CPU of a main system outputs a power control signal set to High, and determines the necessariness of information display on an LCD of an operation unit control system to output a starting mode selection signal set to High when the result of the determination is positive. A CPU of the operation unit control system detects the state of a power control signal, and detects mode return from the energy-saving mode depending on the result of the above detection. The CPU of the operation unit control system also detects the state of a starting mode selection signal, and determines the necessariness of information display on the LCD depending on the result of the detection to carry out a display process depending on the result of the determination.
