In the bad book not binding circuit shown in the above figure, YV1 is the execution solenoid valve that controls the machine head to the bad book. In the normal case without the bad book signal, the left tube VTI of the flip-flop is cut off, the right tube VT2 is turned on, at this time, the collector voltage of VT2 is ov. If a bad book signal enters the flip-flop, the flip-flop is turned over, and its state is that the left tube VT1 is turned on, the right tube VT2 is turned off, and the collector voltage of the vri is +9. . 5V. This signal is amplified by VI'3, and the control VT4 is turned on, so that the relay Kl is sucked, the electromagnetic 阎 YV1 is actuated, and the control head is not bound to the bad book.
Litecoin is an online currency based on peer-to-peer technology and is an open source software project under the MIT/X11 license. It can help users make instant payments to anyone in the world [2]. Litecoin was designed and programmed by a programmer (Li Qiwei) who used to work at Google, and launched on January 9, 2011. Litecoin is an improved digital currency inspired by Bitcoin. The technical principle of Litecoin is the same as that of Bitcoin. It also adopts a decentralized architecture, without any central authority control, and the issuance of new coins and the transfer of transactions and payments are based on open source encryption algorithms, etc. These are all imitated the design principle of Bitcoin. However, Litecoin tries its best to improve the shortcomings that Bitcoin has shown before, such as too slow transaction confirmation, small total cap, the emergence of large mining pools caused by proof-of-work mechanism and so on, SHA256 algorithm [1].
Litecoin, which aims to improve Bitcoin, has three significant differences. First, the Litecoin network can process a block every 2.5 minutes instead of 10, thus providing faster transaction confirmation. Second, the Litecoin network is expected to produce 84 million litecoins, four times the amount of money issued on the Bitcoin network. Each litecoin is divided into 100 million smaller units, defined by eight decimal places.
