Title: Underframe equipment suspension seat
Inventor: ZENG YAOZHENG
IPC: B61G7/10
Filed: 2018-09-27
Abstract: An underframe equipment suspension seat comprises a suspension seat (1), an upper adjustment pad (4), and an equipment supporting pad plate (5). The suspension seat (1) comprises a base plate for bearing the upper adjustment pad (4). The base plate is provided with an adjustment hole. A lower surface of the upper adjustment pad (4) engages with an upper surface of the base plate. The upper adjustment pad (4) is rotatably adjustable relative to the base plate in a lateral direction of a vehicle. The equipment supporting pad plate (5) is disposed on upper adjustment pads (4) of adjacent suspension seats so as to span across the same. In the underframe equipment suspension seat, an upper adjustment pad rotates along an arc-shaped surface of a base plate, eliminating a wedge-shaped gap resulting from insufficient flatness of the equipment mounting seat, without requiring the addition of a wedge adjustment pad to perform adjustment, thereby ensuring that a screw of an equipment mounting bolt is only subjected to a force in an axial direction, standardizing equipment suspension seats, and improving productivity.

Title: Mobile terminal
Inventor: CHENG JIAO
IPC: H04M1/02
Filed: 2018-10-30
Abstract: A mobile terminal includes a rear housing, a display screen, a mounting seat and a photographing module. The rear housing includes a first surface, a second surface, a first side circumference, a second side circumference, a third side circumference and a fourth side circumference. The second surface is sunken toward the first surface to form a groove. The display screen is arranged at one side where the first surface is located. The mounting seat is rotatablely connected to the rear housing. A rotation axis of the mounting seat passes through a circle center of a circumcircle of a positive projection of the mounting seat on a reference plane. The photographing module is arranged on the mounting seat. The mounting seat is capable of being rotated relative to the rear housing through a first position and a second position. When the mounting seat is at the first position, the photographing module is located in the groove, and a first light entering surface of the photographing module is blocked by the display screen. When the mounting seat is at the second position, the photographing module is located out of the groove and the first light entering surface is exposed from one side where the display screen is located. The above mobile terminal is beneficial to implementing the high screen-to-body ratio of the mobile terminal.

Abstract: An asymmetric tetradentate metal complex of a N^C^C^N comprising tetradentate ligand has a metal connected to binding sites which are connected to each other via three or four covalent bonds that can be either single or double bonds with bridging linkers reside between C^C and C^N moieties. These linkers result in three-dimension metal complexes with distorted square planar geometries. The four donor atoms coordinate to a metal center. Upon metal binding a 5-6-6 membered metallocycle is formed upon chelation including a first nitrogen donor bond, a first metal-carbon bond, a second metal-carbon bond, and a second nitrogen donor bond. The light emission from these metal complexes can be tuned by the ligand structure over the entire visible spectrum.

Title: Synnotch receptor-regulated expression of il12
Inventor: LI ZONGHAI
IPC: C12N15/90
Filed: 2019-01-21
Abstract: A binary vector and the provision of expression of a target antigen-dependent regulatory cytokine using the synNotch technology, so as to partially release the cytokine to enhance the function of T cell and reduce the non-specific toxic and side effect of the cytokine. A synthetic notch receptor is used to construct plasmid vectors to achieve local cytokine secretion. One plasmid vector uses a specific antibody as an extracellular domain for identifying a target antigen, a notch core comprises a transmembrane domain and a specific enzyme cutting site on a notch receptor, and transcription factor GAL4VP64 is used as an intracellular domain. When the target antigen is identified, the enzyme cutting site on the notch will be identified by a corresponding enzyme to hydrolyze and cut the intercellular transcription factor GAL4VP64. Another plasmid vector carries DNA identification/binding domain GAL4UAS of transcription factor GAL4 and correspondingly activates a minimal promoter of a target gene, and after being hydrolyzed and cut, GAL4VP64 will be bound to the binding domain to activate transcription of subsequent genes so as to express IL12 and secrete same out of the cell.
