ring counter

To counter the fake crabs, the Suzhou Crab Business Association demanded that a plastic ring with a special numerical code be attached to one of the claws of each original Yangcheng hairy crab.

为了应对假冒的阳澄湖大闸蟹，苏州螃蟹协会要求在每只正宗的阳澄湖大闸蟹的钳子上系一个印有数字编码的塑料圆环，以此作为正宗阳澄大闸蟹的标志。

Three chips of microcomputer are used to perform three different functions, the first for dual PID controller in voltage and current loops, the second for pulse-triggered circuit in the thyristor converter and the third for the nonlinear function generation and ring counter in the inverter.

三片单片机分别实现电压与电流反馈环中的数字PID调节器，晶闸管变流器的脉冲触发电路，以及非线性函数发生器和脉冲环形分配器。

It uses programmer timing counter producing pulse, lock phase ring controling automatic rise-fall velocity. It realizes preferably working procedure example for making package, fill, seal and cutting off etc. in phase.

该设计采用了可编程定时计数器实现控制脉冲的产生，采用锁相环实现自动升降速的控制，能够实现制袋、下料、封口和切断等工序的同步工作。

Why don't you come to the counter and I ring up your purchases ?

请您到柜台来.我帮您 结帐 .

The advantage of the modified ring counter is that it is self-starting.

改进的环形计数器的优点是可以 自行 起动.
