  • Patent number: 11464158
    Abstract: The present invention discloses an opposite belt-type precise seeding device. The opposite belt-type precise seeding device comprises a seed metering tube consisting of a U-shaped shell and a cover plate, two conveying devices provided inside the seed metering tube in parallel, and a conveying plate provided at the lower end of the seed metering tube. The opposite belt-type precise seeding device belongs to the field of agricultural machinery. In a seeder, a tubular seed conveying tube is usually used for guiding movement of seeds, but the movement of the seeds in the seed conveying tube has certain randomness, so that the seed distance consistency of the seeds in a seed bed is reduced. Through control of the seeds by the conveying devices, the stable movement of the seeds is achieved and the seed distance consistency of the seeds in the seed bed is guaranteed.

  • Patent number: 11446270
    Abstract: This invention belongs to the modern pharmaceutical field of Traditional Chinese Medicine, and relates to an herbal extract of Chinese Motherwort and its application in pharmacy, which specifically relates to the crystal structure of a Chinese Motherwort extract: Leonurine, and its application in the preparation of medicine. The chemical name of the above-mentioned Leonurine is 4-guanidino-1-)butyl 4-hydroxy-3,5-dimethoxybenzoate. The invention by specific methods prepares leonurine as 6 kinds of crystals with different crystal forms. Specifically, there are six different structures of leonurine sulfate crystals, two of them are hydrate, two are anhydrous crystal form, one is methanol solvate, one is ethanol solvate. The leonurine crystal forms of this invention can applicate in preparing medicine such as insulin sensitizer, hypoglycemic and lipid-lowering drugs.

  • Publication number: 20220216156
    Abstract: The present disclosure discloses an FPGA device forming a network-on-chip by using a silicon connection layer. An active silicon connection layer is designed inside the FPGA device. A silicon connection layer interconnection framework is arranged inside the silicon connection layer. Bare die functional modules inside an FPGA bare die are connected to the silicon connection layer interconnection framework to jointly form the network-on-chip. Each bare die functional module and a network interface and a router that are in the silicon connection layer interconnection framework form an NOC node. The NOC nodes intercommunicate with each other, so that the bare die functional modules in the FPGA bare die without a built-in NOC network can achieve efficient intercommunication by means of the silicon connection layer interconnection framework, reducing the processing difficulty on the basis of improving the data transmission bandwidth and performance inside the FPGA device.

  • Publication number: 20220119836
    Abstract: The invention discloses a rice temperature sensitive male sterile gene mutant tms18 and its uses. During the study of TMS18 gene, the inventors found that the changing of fertility was related to the structural integrity of the second layer of pollen outer wall. The inventors accidentally found the thermo sensitive male sterile mutant tms18. The fertility of the mutant was affected by different temperatures and can be restored under low temperature treatment. More importantly, the fertility sensitive period of the mutant was different from that of other thermo sensitive male sterile genes. This unique feature of the gene can provide a new theoretical basis and apply value for two-line hybrid rice breeding.

  • Publication number: 20220006733
    Abstract: The present disclosure discloses an FPGA device for implementing a network-on-chip transmission bandwidth expansion function, and relates to the technical field of FPGAs. When a predefined functional module with built-in hardcore IP nodes is integrated in an FPGA bare die, soft-core IP nodes are configured and formed by using logical resource modules in the FPGA bare die and are connected to the hardcore IP nodes to form an NOC network structure, so as to increase nodes and expand the transmission bandwidth of the predefined functional module. On the other hand, the soft-core IP nodes can be additionally connected to input and output signals in the predefined functional module and also can expand the transmission bandwidth of the predefined functional module.

  • Publication number: 20210315115
    Abstract: Disclosed are an electronic device, an expansion card assembly and a server device. The electronic device comprises a hard disk slot and the expansion card assembly. The expansion card assembly is arranged in the hard disk slot in a pluggable manner; the hard disk slot comprises a first type of interface and a second type of interface. The first type of interface is used for communicating with the hard disk, and the second type of interface is used for communicating with the expansion card assembly. Therefore, the expansion card assembly is expanded by means of the hard disk slot in the electronic device, so that the expansion requirement of the expansion card assembly is met.
