    • A method to configure an apparatus to obtain a color image for printing. The apparatus presents the printing option of converting the color image into a standard monochrome image or a color-highlighted monochrome image. Black colored portions of the original color image are shown to be predominantly darker in the standard monochrome image. Colored portions, of a predetermined color of the original color image, are shown to be predominantly darker in the color-highlighted monochrome image, and black colored portions, of the original color image, are less prominent. The apparatus applies filters to the color image to produce the standard or color-high-lighted monochrome image, and outputs whichever option is selected by the user.
    • 一种配置设备以获得用于打印的彩色图像的方法。 该装置呈现将彩色图像转换为标准单色图像或彩色突出显示的单色图像的打印选项。 原始彩色图像的黑色部分显示为在标准单色图像中主要较暗。 在彩色突出显示的单色图像中,原色图像的预定颜色的彩色部分显示为主要较暗,原始彩色图像的黑色部分不太突出。 该设备对彩色图像应用滤光片以产生标准或彩色高亮度单色图像,并输出用户选择哪个选项。

    • When applying a high frequency voltage which alternates on positive and negative sides to a permanent magnet synchronous motor, a driving system of synchronous motor switches the applied voltage phase by 120 degrees successively and applies resultant voltages to three phases. A pulsating current generated by applying a high frequency voltage is detected at timing of elapse of a predetermined time Δt since an output voltage of at least one phase has changed from a state in which all output voltages of the three phases of a power converter are positive or negative. Current detection is conducted by using a DC resistor or a phase current sensor provided on a DC bus. A magnetic pole estimation unit calculates the rotor magnetic pole position of the permanent magnet synchronous motor on the basis of differences between positive side and negative side change quantities in three-phase currents obtained from detected current values.
    • 当施加在正极和负极侧交替永磁同步电动机的高频电压时,同步电动机的驱动系统连续地将施加的电压相位切换120度,并将合成的电压施加到三相。 由于至少一相的输出电压已经从功率转换器的三相的所有输出电压的状态发生变化,所以在经过预定时间&Dgr; t的定时检测施加高频电压而产生的脉动电流 是正或负。 通过使用直流母线上提供的直流电阻或相电流传感器进行电流检测。 磁极估计单元根据从检测到的电流值得到的三相电流的正侧和负侧的变化量之差,来计算永磁同步电动机的转子磁极位置。

    • A torque transmission device is provided wherein a rotary housing is connected to one of front and rear drive shafts which respectively drive front and rear axles of a four-wheel drive vehicle, while a rotary shaft coaxially carried by the rotary housing is connected to the other of the front and rear drive shafts. The housing receives therein a multiple disc clutch device for transmitting rotational power between the housing and the shaft through friction engagement between alternately arranged outer and inner clutch discs which are respectively rotatable bodily with the housing and the shaft. The housing also receives an axially movable piston to press the clutch discs for friction engagement. An end wall of the housing or an end cap secured thereto and a facing end surface of the piston define an axially narrow circular chamber, within which a rotor with a plurality of radially extending blade portions provided with a pair of slanted surfaces is received to be rotated by the shaft. A several space sections into which the chamber is divided by the rotor blade portions are filled with silicon oil of a high viscosity. When the rotational speed difference occurs between the rotor and the housing, a pressure is generated within each of the space sections thanks to the high viscosity of the silicon oil and is directly applied to the piston, whereby rotational power is transmitted from the housing to the rotary shaft and vice versa.
    • 提供了一种转矩传递装置,其中旋转壳体连接到分别驱动四轮驱动车辆的前轴和后轴的前驱动轴和后驱动轴中的一个,同时由旋转壳同轴承载的旋转轴连接到另一个 的前驱动轴和后驱动轴。 壳体容纳有多个盘式离合器装置,用于通过交替布置的外离合器盘和内离合器盘之间的摩擦接合来传递旋转动力,所述外离合器盘和内离合盘分别可旋转地与壳体和轴一起旋转。 壳体还接收可轴向移动的活塞以按压离合器盘以进行摩擦接合。 壳体的端壁或固定到其上的端盖和活塞的面对端面限定轴向窄的圆形室,其中具有设置有一对倾斜表面的多个径向延伸的叶片部分的转子被接收为 由轴旋转。 由转子叶片部分分隔室的几个空间部分填充有高粘度的硅油。 当转子和壳体之间产生转速差时,由于硅油的高粘度而在每个空间部分内产生压力,并且直接施加到活塞上,由此旋转动力从壳体传递到 旋转轴,反之亦然。
