    • Techniques are described for analog-to-digital signal conversion. According to exemplary embodiments, a first request is associated with a changeable set of a plurality of input terminals, a second request is associated with a changeable one of the input terminals, and a third request is associated with a fixed one of the input terminals. One of the first, second, and third requests is received, and an analog signal presented at one of the input terminals is converted into a digital value based on the received one of the first, second, and third requests. When one of the second and third requests is received while converting a plurality of analog signals presented at the changeable set of the input terminals, a determination can be made whether the changeable set of the input terminals includes the one of the changeable and fixed input terminals associated with the received request.
    • 描述了用于模数转换的技术。 根据示例性实施例,第一请求与多个输入终端的可变组相关联,第二请求与可变的输入终端相关联,并且第三请求与固定的一个输入终端相关联。 接收第一,第二和第三请求中的一个,并且基于所接收到的第一,第二和第三请求中的一个,将在一个输入端子处呈现的模拟信号转换成数字值。 当在转换在可变组输入端子处的多个模拟信号的同时接收到第二和第三请求之一时,可以确定输入端子的可变组是否包括可变和固定的输入端子之一 与所接收的请求相关联。

    • A fixing device for forming a toner image formed on a recording medium includes a heat roller accommodating a radiation heater. The radiation heater includes a glass tube formed of transparent quartz and provided with a wall thickness of 0.8 mm or below to increase transmission thereof. The increased transmission reduces a heat loss ascribable to the glass tube at the time of warm-up of the fixing device. The heat roller has such a thermal capacity that it can be warmed up in 10 seconds or less. The glass tube is filled with inactive gas whose major component is krypton or xenon. A tungsten filament accommodated in the glass tube has its diameter reduced in order to implement a color temperature of 2,500 K or above. An image forming apparatus uses the fixing device.
    • 用于形成在记录介质上形成的调色剂图像的定影装置包括容纳辐射加热器的加热辊。 辐射加热器包括由透明石英形成并且具有0.8mm或更小的壁厚以增加其透射率的玻璃管。 增加的传输减少了在定影装置预热时归因于玻璃管的热损失。 加热辊具有这样的热容量,可以在10秒以内加热。 玻璃管填充有主要成分是氪或氙的惰性气体。 容纳在玻璃管中的钨丝的直径减小,以实现2500K或更高的色温。 图像形成装置使用定影装置。
