    • A control system for controlling a lock-up clutch of a torque converter employed in an automatic transmission of a vehicle, the lock-up clutch being controllable by a pressure differential between apply and release pressures comprises a detector for detecting a demand of change (decrease/increase) in the pressure differential, a pressure-differential setting circuit for setting a target pressure differential in response to the demand of change in the pressure differential, and a pressure-differential filter having a desired dynamic characteristic and being responsive to the target pressure differential for outputting a filtered pressure-differential command value via a filtering process based on the desired dynamic characteristic. A pressure-differential regulation circuit is connected to the pressure-differential filter for receiving the filtered pressure-differential command value as an input information data to generate an output indicative of a duty ratio to be output to a lock-up solenoid valve and for regulating the pressure differential in accordance with the duty ratio.
    • 一种用于控制在车辆的自动变速器中使用的变矩器的锁止离合器的控制系统,所述锁止离合器由施加和释放压力之间的压力差控制,包括用于检测变化需求的检测器(减小 /增加),用于响应于压差变化的要求设定目标压差的压差设定电路和具有期望动态特性并且对目标压力作出响应的压差微分滤波器 用于通过基于期望的动态特性的滤波处理来输出经滤波的压差指令值的差分。 压力差调节电路连接到压差微分滤波器,用于接收经滤波的压差指令值作为输入信息数据,以产生指示输出到锁定电磁阀的占空比的输出,并用于调节 压差按照占空比。

    • The present invention provides a printed circuit board installed in a lens barrel with an imaging optical system. In an installed state, the printed circuit board comprises: a ring-shaped portion disposed substantially perpendicular to the optical axis of the imaging optical system wherein an aperture is provided at a central portion of the ring-shaped portion so that an imaging light beam may pass through the aperture; and an extending board portion that extends outward from the ring-shaped portion wherein electrical components may be mounted on the surface of the extending board portion. After the ring-shaped portion and the extending board portion have been bent, the above-described flexible printed circuit board is inserted into the lens barrel in such a manner that the plane of the extending board portion on which the electrical components are mounted is parallel to the optical axis of the imaging optical system. This printed circuit board provides high efficiency electrical interconnections in the lens barrel.
    • 本发明提供一种安装在具有成像光学系统的镜筒中的印刷电路板。 在安装状态下,印刷电路板包括:基本上垂直于成像光学系统的光轴设置的环形部分,其中在环形部分的中心部分处设置孔,使得成像光束可以 通过光圈; 以及从环形部分向外延伸的延伸板部分,其中电部件可以安装在延伸板部分的表面上。 在环状部分和延伸板部分弯曲之后,将上述柔性印刷电路板插入透镜镜筒中,使得安装有电气部件的延伸板部分的平面平行 到成像光学系统的光轴。 该印刷电路板在镜筒中提供高效率的电互连。
