GGII data shows that in 2019, the sales volume of SCARA in the Chinese market was 29100 units, down 1.02% year on year. After experiencing rapid growth in the past few years, SCARA robot will decline for the first time in 2019, which reflects the change and transfer of downstream industry demand in 2019. Even so, GGII statistics show that in 2019, 13 enterprises including ABB, Fanuc, Stober, Yamaha and other international brands, as well as domestic brands such as Huashu Robot, Zhongweixing, Tianji Robot, and Tostar have launched new functions or new models of SCAR [Detailed]

According to foreign media reports, a team led by researcher Liu Zhaoping from Ningbo Institute of Materials Technology and Engineering (NIMTE), Chinese Academy of Sciences, proposed an analytical method that can accurately quantify the reversibility and irreversibility of actual lithium metal batteries. (Picture source: Chinese Academy of Sciences) Lithium metal batteries have excellent energy density and are an important focus in the field of battery technology. However, the poor electrochemical reversibility of lithium metal anode has become the bottleneck of improving the cycle life of lithium metal batteries. Therefore, accurate analysis of the reversibility of lithium metal anode is an important prerequisite for the development of long-life lithium metal batteries. In the lithium battery cycle [Detailed]

Improper use of cables may cause the problem of too long measurement time. The coaxial cable provides an inner conductor and shield for transmitting signals. There are bypass resistance and capacitance paths between the inner conductor and the shield for leakage current to flow through (Figure 4). In addition to being the path of leakage current, R and C of bypass also constitute an RC circuit, which will greatly slow down the speed of low current or high resistance measurement, and it is generally necessary to wait for 5 times the time constant of RC to achieve accurate reading. To measure extremely high resistance GW or even higher, it takes several seconds to several minutes to stabilize the reading to within 1% of the final value [Detailed]

At present, the general alarm sending system is a half duplex point to multipoint antenna dedicated remote control network based on PC/MCU technology. The control center of the system is PC/IPC, and each executive terminal uses a controller with a single chip microcomputer as the core to perform control functions. From the perspective of use management and construction, there are the following shortcomings: the control center based on PC/IPC technology has a large unit volume, high equipment cost, and the use efficiency is not high because of the relatively simple tasks it undertakes, while the control execution terminal based on SCM technology can better complete the decoding control function, but it can not meet the information interaction improvement and alarm sending technology [Detailed]

BASIC language has developed into QuickBASIC, Visual Basic, and has many structural ideas and programming methods, such as functions, modules, local variables, global variables, data transfer, etc. The early BASIC language was inefficient because the generated code was not the code of the final target machine, but was run after being interpreted by a RUNTIME program. The BASIC compiler of the MCU directly compiles the code into the machine code of the corresponding chip, and does not need to reside the RUNTIME program in the memory of the MCU, so the execution effect is [Detailed]

1. LED backlight meets the market green and environmental protection concept at this stage. Large size TV backlight is mainly straight down type. At present, European Union standards, domestic standards, and products must meet RoHS standards and UL standards. Later, halogen-free requirements have been added. The widely used CCFL products now contain Hg in the lamp tubes. Because of this characteristic, an exemption for this substance has been added to the standard, which means that the substance is qualified and usable in a certain amount. However, the substances containing Hg in CCFL are still in violation of the current environmental protection requirements. The current product requirements are green [Detailed]
