Chengdu Full Search News Network (Reporter Hu Ke) reported on February 13th today, the reporter learned from the Municipal Rail Office that the Incubation Park Station of Metro Line 9 and Jincheng Square Station of Metro Line 18 are the pilot sites for the early "tailor-made" rail transit construction projects to resume work, and all seven working sites of the first batch of rail transit construction projects have reached the standard. In order to go all out to carry out epidemic prevention and control of rail transit construction projects and guarantee the resumption of work, the Municipal Rail Office has carried out precise policies, conducted a comprehensive survey of the employees of rail transit projects in the city, and guided the participating units to prepare for the resumption of epidemic prevention from seven aspects: comprehensive personnel investigation, setting up special posts for special personnel, setting up isolation areas, wearing masks, having disinfectant materials, implementing closed management, body temperature monitoring, and resuming epidemic prevention. What is the specific situation? Today, the reporter visited the Incubation Park Station of Metro Line 9 on the pilot site.
Closed project management Every day, all the people in and out take their body temperatures twice. Incubation Park Station, the first phase project of Chengdu Rail Transit Line 9, as the first batch of resumption sites, passed the resumption audit on February 7 and was officially approved to resume work. According to the relevant…

In 2020, the Shanghai Electronics Show in Munich ushered in early summer for the first time. The sunny and passionate summer is as pleasant as the atmosphere of Shanghai Electronics Show in Munich. The outbreak of the epidemic at the beginning of the year has had some impact on the development of the electronics industry this year, but more has brought new development opportunities! As the first large-scale professional exhibition in the electronic industry held after the China epidemic, Munich Shanghai Electronics Show contributed to the economic recovery of China, which not only met the needs of exhibitors and visitors accumulated for half a year, but also reflected its role as a benchmark and lighthouse for the electronic industry exhibition.
This year’s exhibition, together with the 2020 Munich Electronic Production Equipment Exhibition (productronia China), attracted nearly 1,373 exhibitors. The exhibition area reached 90,000 square meters, and 81,126 professional visitors were received in three days. The superposition of the four events shows the whole electronic industry chain in an all-round way, which is an ideal…

This year, Hillary Creech – the parent of a 10th grader and wife to a teacher – had an unusual back-to-school shopping list.
She ordered a box fan, some high-quality air filters, and a lot of duct tape. Why? To make a homemade air purifier for the local high school where her husband teaches. As an emergency room nurse practitioner, Creech has seen firsthand what the pandemic is doing, and, she says, she’s been treating a lot…

Arguably, one of the most useful, simple, circuit configurations is this connection of two transistors into a four layer device equivalent to a Unijunction transistor. It is also possibly one of the least valued and least understood of simple circuits. In fact when I started looking out circuits for this page I surprised myself by just how m uch I had to say about such a simple, two transistor circuit! Yet perhaps I should not be surprised for GE wrote an entire book on the applications of Unijunction transistors and, in performance, this configuration has a lot in common with the UJT. The basic connection of the 4 layer device is shown in the diagram below and the configuration is the basis of Thyristors (or SCRs – Silicon Controlled Rectifiers), Triacs, diacs, SBSs (Silicon Bilateral Switches) as well as the Programmable Unijunction or PUT.
When neither transistor conducts, then no current flows. However as soon as any current flows in either transistor, this current becomes base current for the other and both transistors turn each other hard on. This means that you must use good, low leakage transistors to make this circuit or the leakage current will cause…

3.3 Logical address mapping
In batch data transmission with the host, firstly, the CBW command sent by the host is parsed, so that the firmware can obtain the LBA requested by the host for data transmission, and then the LBA address is mapped to obtain the corresponding PBA, and then the host command is executed. Specific methods: First,…
