  • Publication number: 20200156668
    Abstract: A waste exhaust ventilation door automatic control device comprises a core body (8), an inner door body (2) and an outer door body (1); wherein the core body is fixed on a ventilation opening of the waste exhaust ventilation door, a top of the outer door body is movably hinged on an outer side of the core body, and a bottom of the inner door body is movably hinged on an inner side of the core body; when there is no pressure fluctuation outside the core body, the outer door body and inner door body will open, and when there is pressure fluctuation outside the core body, the outer door body and/or the inner door body will be closed automatically due to a pressure difference between inside and outside the core body. A vehicle body comprising the waste exhaust ventilation door automatic control device is also provided.

  • Patent number: 10600766
    Abstract: A dual-channel heat-conducting encapsulation structure of a solid-state phosphor integrated light source has a solid-state phosphor, a transparent organic silica gel, LED chips and a substrate. The LED chips are arranged on the substrate. The dual-channel heat-conducting encapsulation structure also has heat-conducting columns fixed on the substrate, and the heat-conducting columns are disposed away from the LED chips; the solid-state phosphor is placed on the heat-conducting columns without contacting the LED chips; the transparent organic silica gel is filled in the gap between the solid-state phosphor and the substrate. By adopting the design of double heat-conducting channels, separates two heat sources of the LED light source to sufficiently conduct the heat, the heat of the solid-state phosphor and the LED chips reaches the substrate through the respective channels, and then is transferred from the substrate through the heat sink into the atmosphere.

  • Patent number: 10563205
    Abstract: This invention discloses a nucleic acid aptamer AS1411 modified DNA tetrahedron. The preparation method includes the steps of (1) binding an AS1411 sequence to the 5? terminal of any DNA single-strand in a DNA tetrahedron, synthesizing the DNA, dissolving obtained DNA powder with ddH2O; (2) measuring an absorbance of the DNA and then calculating a total volume of the four single strands; (3) pipetting the DNA obtained in step (1) according to the calculation results in step (2), mixing the DNA with a TM buffer, mixing the mixture uniformly with vortex vibration, and performing a PCR progress. The preparation method is simple. The produced product can effectively solve the problem that the unmodified DNA tetrahedron cannot enter the nucleus and the problem that the AS1411 cannot carry drugs directly.

  • Patent number: 10507246
    Abstract: This invention discloses a method for preparing TDNs-AS1411-nucleic acid drug nanocomposite based drug delivery system, which includes the following steps: binding AS1411 and nucleic acid drug to a tetrahedral DNA nanostructure respectively; selecting four DNA single strands that respectively carry AS1411 and nucleic acid drug; mixing the four DNA single strands; mixing the DNA single strands and the TM buffer uniformly; putting the mixture into a PCR apparatus; raising the temperature to 95° C. quickly and maintaining for 10 min; and next cooling down to 4° C. and maintaining for 20 min to obtain the TDNs-AS1411-nucleic acid drug nanocomposite based drug delivery system. This drug delivery system can directly act on cell nucleus and will not be degraded by lysosomal. The targeting specificity is good. The drug can take a good efficacy and the pertinency is high.

  • Patent number: 10504875
    Abstract: A die-bonding substrate has a substrate, and a conductive line layer and a chip array provided on the substrate. The conductive line layer includes a chip welding wire region and an external electrode region connected with each other. The chip welding wire region is composed of multiple conductive lines, wherein the central conductive line located in the central position of the chip welding wire region is a straight line section. The conductive lines arranged at both sides of the central conductive line are straight line sections at both ends, and arc sections curved outwards in the middle, so that the entire chip welding wire region forms a circular area. The array chips are arranged inside the circular area, and are electrically connected with the conductive lines arranged at both sides. The entire chip welding wire region can also form a rectangular area.

  • Publication number: 20090110065
    Abstract: Generation, coding and transmission of an effective video form, scalable portrait video. As an expansion to bi-level video, portrait video is composed of more gray levels, and therefore possesses higher visual quality while it maintains a low bit rate and low computational costs. Portrait video is a scalable video in that each video with a higher level always contains all the information of the video with a lower level. The bandwidths of 2-4 level portrait videos fit into the bandwidth range of 20-40 Kbps that GPRS and CDMA 1X can stably provide. Therefore, portrait video is very promising for video broadcast and communication on 2.5 G wireless networks. With portrait video technology, this system and method is the first to enable two-way video conferencing on Pocket PCs and Handheld PCs.
