    • A clutch device which transmits torque by causing multiple friction engagement elements to engage with each other by use of a clutch connection/disconnection member caused to operate by an electric actuator includes: an elastic member disposed between the clutch connection/disconnection member and the multiple friction engagement elements; position detector for detecting a position of the clutch connection/disconnection member; and controller for controlling an operation of the electric actuator on the basis of the position of the clutch connection/disconnection member detected by the position detector. Thus, the position of the clutch connection/disconnection member (i.e. a stroke amount of the elastic member) and a torque transmission capacity of the clutch device have a linear relationship with each other. Hence, the torque transmission capacity of the clutch device can be accurately controlled by the electric actuator.
    • 一种通过使多个摩擦接合元件通过使用由电致动器操作的离合器连接/断开构件彼此接合来传递扭矩的离合器装置,包括:设置在离合器连接/断开构件和多重摩擦之间的弹性构件 订婚元素 位置检测器,用于检测离合器连接/断开构件的位置; 以及控制器,用于基于由位置检测器检测到的离合器连接/断开部件的位置来控制电致动器的操作。 因此,离合器连接/断开部件的位置(即弹性部件的行程量)和离合器装置的扭矩传递能力彼此具有线性关系。 因此,能够通过电致动器精确地控制离合器装置的转矩传递容量。

    • A transmission controller for a continuously variable transmission system steadily returns a gear ratio toward the low-ratio range, even after a driving pulley has stopped during sudden deceleration. A control unit is provided which drives an actuator to move a driving-pulley movable half part to a position in the low-ratio range when a vehicle speed sensor detects the sudden deceleration of a body, a pulley number-of-revolution sensor detects stopping of the driving pulley, and then a gear ratio sensor detects that the gear ratio of the continuously variable transmission system has not returned to the low-ratio range where a sufficient acceleration is obtainable at the time of restart. Upon detecting a restart, the control unit presses the driving-pulley movable half part onto a V-belt to prevent sliding therebetween and thereby reduce a loss in the transmission of a driving force at the time of restart.
    • 无级变速器系统的传动控制器即使在急速减速期间的驱动滑轮停止之后,也能够朝低速比范围稳定地返回齿轮比。 提供控制单元,当车速传感器检测到身体的突然减速时,驱动致动器将驱动滑轮可移动半部移动到低比例范围内的位置,皮带轮转数传感器检测停止 ,然后齿轮比传感器检测到无级变速器系统的齿轮比没有返回到在重新启动时可获得足够的加速度的低比率范围。 在检测到重启时,控制单元将驱动带轮可移动半部分按压到V形带上以防止其间的滑动,从而减少重启时的驱动力的传递损失。

    • A base station apparatus switches between a communication mode for performing communication with a communication party and a calibration mode for performing a calibration process. In the calibration mode, a weight vector in accordance with a first algorithm for performing a null steering directivity control for orienting an area of drastically-lowered antenna gain in the direction of arrival of a reception signal. Furthermore, multiple transmission signals weighted by the acquired weight vector are output, and a correction value for readjusting the result of the null steering directivity control is acquired from a control PC. In the communication mode, multiple transmission signals are corrected by using the correction value acquired in a calibration mode, and the corrected signals are output.
