    • A composite MOS transistor device for a semiconductor integrated circuit includes at least a pair of MOS transistors, or first and second MOS transistors, placed on the same board. The first and second MOS transistors are made up of first and second groups of equally divided transistors with an equal gate width, respectively. These divided transistors are arranged in parallel to each other in the gate longitudinal direction. The divided transistors of these groups are arranged such that the sum of coordinates of respective gates, measured from a centerline, is equalized between these groups along the gate longitudinal direction. Since the sum of errors of respective gates along the length thereof becomes zero in each group of divided transistors, the current difference between the two MOS transistors can be eliminated. Accordingly, in forming a differential amplifier or a current mirror circuit using this MOS transistor pair, high current gain can be obtained while maintaining an adequate balance in output current.
    • 用于半导体集成电路的复合MOS晶体管器件至少包括一对放置在同一板上的MOS晶体管或第一和第二MOS晶体管。 第一和第二MOS晶体管分别由具有相等栅极宽度的等分分割晶体管组成。 这些分离的晶体管在栅极纵向方向上彼此平行地布置。 这些组的分割晶体管被布置成使得从中心线测量的各个栅极的坐标之和在栅极纵向方向上在这些组之间相等。 由于各组栅极沿其长度的误差之和在每组分割晶体管中变为零,所以可以消除两个MOS晶体管之间的电流差。 因此,在形成使用该MOS晶体管对的差分放大器或电流镜电路时,可以在保持输出电流的充分平衡的同时获得高电流增益。

    • An electrophotographic printer includes a transfer roller which rotates in contact with a cylindrical photoconductive drum. When print paper passes through a transfer point where the transfer roller is in contact with the photoconductive drum, a toner image on the photoconductive drum is transferred from the photoconductive drum to the print paper. A paper guide is disposed upstream of the transfer point with respect to a transport path of the print paper. The paper guide changes the direction of travel of the print paper so that the leading end portion of the print paper enters the transfer point in a direction substantially tangent to a circumferential surface of the photoconductive drum.

    • An inductor 6 accumulates an energy therein or releases the accumulated energy according to the state of a main switch element 10 being turned ON/OFF. When the inductor 6 releases an energy, if a sub-switch element 12 is in the ON state, a current is passed through a circuit downstream of the sub-switch element 12, thereby increasing an output voltage VO1. The sub-switch element 12 is a P-channel MOS transistor, and a sub-switch control circuit 18 outputs a control signal VCT1 for the sub-switch element 12. A level shift circuit 19 receives an output-side potential VP of the inductor 6, and outputs, as a control signal VG1 applied to the gate of the sub-switch element 12, the potential VP if the control signal VCT1 is at the L level or a potential (VP−VM) lower than the potential VP if the control signal VCT1 is at the H level. Thus, the output voltage of the DC-DC converter can be made precisely equal to the target voltage.
    • 电感器6在其中累积能量,或者根据主开关元件10被接通/断开的状态释放累积的能量。 当电感器6释放能量时,如果副开关元件12处于导通状态,则电流通过副开关元件12下游的电路,从而增加输出电压VO 1。 副开关元件12是P沟道MOS晶体管,副开关控制电路18输出副开关元件12的控制信号VCT1。 电平移位电路19接收电感器6的输出侧电位VP,并且如果控制信号VCT 1处于电平位置,则作为施加到副开关元件12的栅极的控制信号VG1输出电位VP L电平或电位(VP-VM)低于电位VP,如果控制信号VCT 1处于H电平。 因此,可以使DC-DC转换器的输出电压精确地等于目标电压。
