    • A new method of refreshing a dynamic RAM, uses relatively simple circuitry. Refreshing of the dynamic RAM can be implemented while smoothly accessing any a real-time based high-speed devices such as a floppy disc driver.In a microprocessor system comprising a central processing unit (CPU), a dynamic RAM, and a plurality of input/output ports, a refreshing process of the dynamic RAM can occur in one of two modes. When input/output (I/O) accesses are not being performed by the CPU, a burst mode refreshing process takes place. However, when input/output (I/O) accesses are to be performed, a refreshing process of the dynamic RAM can be implemented within a period while the CPU accesses the input/output (I/O) port addresses.
    • 一种刷新动态RAM的新方法,使用相对简单的电路。 可以在平滑地访问诸如软盘驱动器之类的基于实时的高速设备的同时实现动态RAM的刷新。 在包括中央处理单元(CPU),动态RAM和多个输入/输出端口的微处理器系统中,动态RAM的刷新过程可以以两种模式之一发生。 当CPU未执行输入/输出(I / O)访问时,将进行突发模式刷新过程。 然而,当要执行输入/输出(I / O)访问时,可以在CPU访问输入/输出(I / O)端口地址的一段时间内实现动态RAM的刷新过程。

    • An object of the invention is to provide a small-size image reading apparatus which has a high accuracy in image reading, by a different means from the prior arts. A panel includes a plurality of two-dimensionally arranged photoreceptor devices which are interposed between a pair of light-transmitting substrates. At an edge of one of the light-transmitting substrate, a slope is formed, and a light source is opposed to the slope. Light transmitted by reflection on the surfaces of the light-transmitting substrates is emitted on an object which comes in contact with the surface of the panel, and light returned from the object is received by the photoreceptor devices, whereby an image of the object is read. Thus, a direction in which light passes through the panel can be restricted, and the accuracy in image reading can be increased.
    • 本发明的目的是提供一种通过与现有技术不同的方式具有高精度的图像读取的小尺寸图像读取装置。 面板包括插入在一对透光基板之间的多个二维布置的感光体装置。 在透光基板之一的边缘处,形成斜面,并且光源与斜面相对。 在透光基板的表面上通过反射透射的光在与面板的表面接触的物体上发射,并且从物体返回的光被感光体接收,从而读取物体的图像 。 因此,可以限制光通过面板的方向,并且可以提高图像读取的精度。
