That's still a lot of code just to increment a counter with a lock held! 要递增一个加锁的计数器仍然需要编写很多代码!
Drivers will drive to counter after car, Lock the door off to leave; 司机将车开到车台板后,锁好门窗下车离开;
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。
