L Transmitter and receiver is used in pairs in the same channel, and it is also allowed to use in one-many way in the same channel (one transmitter sends signal, several receivers receive in the same channel; it is synchronous and accurate to receive, which is equal to wireless video distributor), or it is also allowed to use in the many-many way (one transmitter occupies 1 channel, and supports 4 channels of video and audio transmission at the very most, which causes no cross fire one another).

l 发送器和接收器在同一信道内成对使用，也可在同一信道内以一对多方式使用（一个发送器发送信号，同一信道内多个接收器接受信号，实现同步精确接收，作用与无线视频分配器等同），或以多对多的方式使用（一个发射器占据一个信道，最多同时支持4信道的音频视频传输，互相不影响）。

One application of this converter is to supply a steady and regulable excitation circuit for synchronous generator by integrated its second winding with the motor while its primary winding is static.

The movement order is that the bag-catcher of the automatic bag-giving device sucks the empty bags on the first stack through the vacuum sucker and lifts it, with the clamping jaw of the clamping tower clamping the lifted empty bag and towing it on the bag-bearing platform of the bag-giving device. The bag central locator locates the empty bag into the center. Then the empty bag held in the center is moved horizontal and sent to the position of the bag-giving manipulator through the bag-shifting pressing wheel downward and bag-shifting synchronous belt.
