    • The watch has a winding weight comprising an arm 10a and an oscillating mass 10b. The arm is mounted for pivotal movement about the axis of a toothed ring 12 by way of which the spring barrel 20 is kept wound and which axis is offset with respect to the watch hand axis X, X'. The oscillating mass 10a is at the same level relative to the case back 6 as the spring barrel 20. The length L' of the winding weight is greater than the offset L and more than half the largest dimension of the case 6. The oscillating mass 10b thus occupies substantially half the casing of the watch and is almost as thick as the distance between the glass and the back 6 which is also the rear plate of the movement.
    • 手表具有包括臂10a和振动块10b的卷绕重量。 臂被安装成围绕齿环12的轴线枢转运动,弹簧筒20保持缠绕,并且哪个轴相对于手表手轴X,X'偏移。 振动块10a相对于弹簧筒20相对于壳背6处于相同的高度。卷绕重量的长度L'大于偏移量L并且大于壳体6的最大尺寸的一半。振荡块 10b因此占据手表的壳体的大致一半,并且几乎与玻璃和背面6之间的距离一样厚,后者也是运动的后板。

    • A push-pull output driver includes a pair of auxiliary, low current capacity output circuits connected in parallel with a pair of high current capacity, series connected devices. In response to a pulse transition at the input of the driver circuit, one of the high current capacity devices is turned on to provide the current necessary for a change in state of the output signal. After the output signal has reached a steady state level, the associated auxiliary low current capacity device is turned on and the high current capacity device is turned off. For the remainder of the duration of the pulse, the relatively low current required to maintain the output signal is provided by the auxiliary gate. At the next pulse transition, the other of the high current capacity gates is turned on. Since the first high current capacity gate was turned off prior to the pulse transition, only one of the high current capacity devices is drawing current from the supply and the need for a large current supply is eliminated. The circuit of the invention allows for the design of very high speed drivers and the totem pole currents which are the source of Delta-I noise do not occur. The driver includes a pulse circuit responsive to voltage levels of the driver output terminals to selectively turn off the primary, high current carrying capacity gates and to selectively turn on and off the auxiliary gates.
    • 推挽输出驱动器包括一对与一对高电流容量串联连接的并联连接的辅助低电流容量输出电路。 响应于驱动器电路的输入处的脉冲转变,高电流容量器件中的一个导通以提供输出信号的状态改变所必需的电流。 输出信号达到稳定状态后,相关的辅助低电流容量器件导通,高电流容量器件关闭。 对于脉冲持续时间的剩余时间,维持输出信号所需的相对低的电流由辅助栅极提供。 在下一个脉冲转换时,另一个高电流容量门被打开。 由于第一高电流容量栅极在脉冲转变之前被关断,所以只有一个高电流容量器件从电源中抽出电流,并且消除了对大电流源的需要。 本发明的电路允许设计非常高速的驱动器,并且不会发生作为Delta-I噪声源的图腾柱电流。 驱动器包括响应于驱动器输出端子的电压电平的脉冲电路,以选择性地关闭初级,高电流承载容量门并选择性地打开和关闭辅助门。
