    • An apparatus includes a system controller which calculates a ratio of a first signal to a second signal and adjusts a control parameter of an electrophotographic reproduction process so that the density of fog indicated by the ratio is within a predetermined range. A first optical sensor outputs the first signal by detecting a reflectance of a non-image area on the photoreceptor between a developing unit and a transfer charger. A second optical sensor outputs the second signal by detecting a reflectance of a surface of the photoreceptor between a cleaning unit and a charger. The system controller controls developer including toner and carrier to be agitated when the ratio obtained after adjusting the control parameter is still outside the predetermined range. Since the density of fog is detected with accuracy by calculating the ratio, copy quality is stabilized even when temperature changes. Moreover, even if the ratio is outside the predetermined range as a result of the supply of toner which has deteriorated due to a heat history, the deterioration of toner is restored by agitating the developer. It is thus possible to prevent copy quality from being degraded.
    • 一种装置包括:系统控制器,其计算第一信号与第二信号的比率,并调整电子照相再现处理的控制参数,使得由比率指示的雾度浓度在预定范围内。 第一光学传感器通过检测显影单元和转印充电器之间的感光体上的非图像区域的反射率来输出第一信号。 第二光学传感器通过检测清洁单元和充电器之间的感光体的表面的反射率来输出第二信号。 当调整控制参数后获得的比例仍然在预定范围之外时,系统控制器控制显影剂,包括调色剂和载体被搅拌。 由于通过计算比例来精确地检测雾的浓度,即使温度变化,复印质量也被稳定。 此外,由于由于热历史而劣化的调色剂的供给,即使该比例在预定范围之外,也可以通过搅拌显影剂来恢复调色剂的劣化。 因此,可以防止复制品质恶化。

    • In a discrimination mode for discriminating a track density mode of an FDD using a carriage mechanism of the lead screw type, on the basis of a reciprocal seek operation of a magnetic head, when a carriage is moved a seek distance dependent on a track density in a forward seek mode, the drive of the carriage mechanism can reliably be stopped. This realizes a reciprocal seek operation of the head that depends on a track density mode of the FDD. Accordingly, a host computer compares the number of pulses contained in a STEP signal in a forward seek stroke with that in a reverse seek stroke, and reliably discriminate a track density mode of the FDD on the basis of the comparison result.
    • 在用于使用导螺杆型的滑架机构识别FDD的轨道密度模式的判别模式中,基于磁头的往返搜索操作,当滑架移动时,取决于轨道密度的寻道距离 前进寻道模式,可以可靠地停止滑架机构的驱动。 这实现了取决于FDD的轨道密度模式的磁头的相互搜索操作。 因此,主计算机将前向搜索行程中的STEP信号中包含的脉冲数与反向搜索行中的脉冲数进行比较,并且基于比较结果可靠地区分FDD的轨道密度模式。

    • A system for performing the desired transaction when the customer follows a specified procedure comprising a sequence of steps includes an electronic visual display unit for displaying a message and a graphic illustration at the same time, and a plurality of functionally operative physically manipulative function units arranged around the display unit. The physical operations are performed by the customer in a sequence of steps, and some of the function units serve different functions for different steps. The display unit displays stepwise, immediately before each of the steps is performed by the customer, an instruction comprising the combination of a procedure specifying textual message describing the procedure to be followed by the customer and a procedure specifying graphic illustration pictorially depicting the physical enactment of the procedure in corresponding relation to the message. In a step in which a function button is to be operated by the customer, the display unit also shows a term indicating the function of the button at a location adjacent and corresponding to the button to be operated and a button frame surrounding the term at least at two sides thereof to indicate the location of the button corresponding to the term.
