    • A power seat drive mechanism for an automobile has a motor which drives a worm which in turn drives a worm wheel at a given speed. The worm wheel is connected to a threaded shaft which it drives to rotate. Rotation of the threaded shaft forces it through a nut which is fixed to the body of the vehicle. This drives the threaded shaft which is connected to the sliding frame of the seat longitudinally with respect to the vehicle. In order to prevent force exerted on the seat in the direction of its travel, from causing the threaded shaft to rotate faster than it is being driven and thus overrun the worm gear, a resilient governor member is included which provides a limited braking effect and tends to resist the rotation of the shaft. With this configuration, backlash in the drive mechanism is eliminated.
    • 用于汽车的动力座椅驱动机构具有驱动蜗杆的马达,蜗杆又以给定的速度驱动蜗轮。 蜗轮连接到驱动旋转的螺纹轴。 螺纹轴的旋转迫使其穿过固定在车身上的螺母。 这驱动螺纹轴,其相对于车辆纵向地连接到座椅的滑动框架。 为了防止在其行进方向上施加在座椅上的力,使得螺纹轴比被驱动更快地旋转,从而使蜗轮超载,包括弹性调节器构件,其提供有限的制动效果并且趋向于 以抵抗轴的旋转。 通过这种配置,可以消除驱动机构中的间隙。

    • An optical information read apparatus for optically reading information recorded on a recording medium includes an optical head for producing two detected signals whose phases vary according to a tracking error of the head, and a tracking error detecting circuit for producing a tracking error signal corresponding to a phase difference between the two detected signals, and a tracking controller for controlling the optical head in response to the tracking error signal. The tracking error detecting circuit has a correlation test circuit for checking a correlation between the states of the two detected signals, and for making the tracking error signal substantially invalid when there is no correlation between the states of the two detected signals. Thus, a stable tracking control can be performed.
    • 用于光学读取记录在记录介质上的信息的光学信息读取装置包括:光头,用于产生根据磁头的跟踪误差而相位变化的两个检测信号;以及跟踪误差检测电路,用于产生对应于 两个检测信号之间的相位差,以及响应于跟踪误差信号控制光头的跟踪控制器。 跟踪误差检测电路具有用于检查两个检测信号的状态之间的相关性的相关测试电路,并且当两个检测信号的状态之间没有相关性时,使跟踪误差信号基本无效。 因此,可以执行稳定的跟踪控制。

    • There is provided an electric guitar including a tremolo unit and first and second string fixing devices. The first string fixing device is adapted to be mounted on the head of the guitar and includes a base and a fixing member for pressing a group of strings onto the surface of the base. The tremolo unit includes a tremolo block rockingly supported by the body of the guitar and having a plurality of through-holes for receiving therein the ends of the strings. The second string fixing device includes a base section integral with the tremolo block and slidingly supporting a plurality of bridges each carrying the corresponding one of the strings and adapted to be moved to adjust tensions developed in respective strings. The second string fixing device further includes means for fixing the strings at the intermediate portions thereof.
    • 提供了包括颤音单元和第一和第二弦固定装置的电吉他。 第一弦固定装置适于安装在吉他的头部上,并且包括底座和用于将一组琴弦按压到基座的表面上的固定构件。 颤音单元包括由吉他的身体摇摆地支撑的颤音块,并且具有多个用于在其中容纳琴弦的端部的通孔。 第二弦固定装置包括与震颤块一体的基部,并且滑动地支撑多个桥,每个桥承载相应的弦之一,并适于移动以调节在各弦中形成的张力。 第二弦固定装置还包括用于将弦固定在其中间部分的装置。
