    • A frequency of a power supply applied to a stepping motor changes in accordance with a predetermined program to control the stepping motor such that a predetermined rotational speed of the motor is quickly obtained without generating noise. The power supply frequency is abruptly and linearly increased or decreased within an initial predetermined time interval. A high accelerating or decelerating torque is applied to the stepping motor to obtain a first rotational speed for a short period of time. Thereafter, the power supply frequency is exponentially decreased or increased within a final predetermined time interval to obtain a second rotational speed at which the noise level is low.
    • 施加到步进电动机的电源的频率根据预定程序而改变,以控制步进电动机,从而快速获得电动机的预定转速而不产生噪声。 电源频率在初始预定时间间隔内突然和线性地增加或减少。 对步进电机施加高加速或减速转矩,以在短时间内获得第一转速。 此后,电源频率在最终预定时间间隔内以指数方式减小或增加,以获得噪声电平较低的第二转速。

    • A vehicle automatic transmission includes a plurality of gears provided on an input shaft, a countershaft, and an output shaft and are meshed with one another. A plurality of hydraulic clutches are each configured to couple any of the gears to the input shaft, the countershaft, or the output shaft to establish a predetermined shift stage. An engagement unit is configured to couple a reverse gear to the input shaft or the countershaft to establish a reverse shift stage. A shift-position detection unit is configured to detect a shift position. A vehicle-speed detection unit is configured to detect a vehicle speed. A control unit is configured to detect, based on an output of the shift-position detection unit, a first time and a second time. The control unit is configured to delay a timing when the engagement unit operates after the shift position changes to an R-position.

    • An objective is to provide a carrier exhibiting stable charge providing ability in which sufficient charge can be provided to toner having a small particle diameter, and no image contamination such as fog caused by toner scattering via lack of electrification is generated. Another objective is to provide a carrier capable of maintaining a charging level of no interference for image formation even under the image forming condition at which a charging level for printing a number of prints continuously is difficult to be maintained. Disclosed is a carrier comprising a core particle made of ferrite possessing Mg and coated thereon, a resin, wherein the core particle has a ratio of the number of irregular-shaped core particles of at most 5%, based on the total number of core particles, and a surface of the core particle has grains having a maximum grain diameter of 2-5 μm.
