Publication number: 20240102386Abstract: The present disclosure relates to a construction method for a deformable anchor cable capable of being prestressed. The anchor cable includes an outer sleeve, a shrinkage pipe, an inner sleeve, a steel strand, an anchor and a tray. When the anchor cable is in use, a hole is drilled first, then the anchor cable is mounted in the drilled hole, and finally a prestress is applied to the steel strand of the anchor cable. According to the construction method, the construction is convenient; the anchor cable has the characteristics of high strength and large deformation, and can be easily prestressed; and the large deformation is realized by squeezing the inner sleeve by means of the anchor, which completely overcomes the problem of breaking a cold-drawn rod during the large deformation process.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Inventors: Xuezhen WU, Yujing JIANG, Tao DENG, Gang WANG, Zhenchang GUAN, Qing YE

Publication number: 20240091366Abstract: The present invention relates to the field of pharmaceutical and chemical engineering, and specifically relates to a weakly acidic microenvironment-sensitive aptamer for tumors, a triptolide conjugate. The conjugate is formed by conjugation between the 14-position hydroxyl group of triptolide and the aptamer via an acetal ester linking bond, which is an acid-sensitive linking bond with a cleavage condition of (pH=3.5-6.5), which is much less pH-sensitive and is more likely to cleave under the tumor microenvironment. Based on the characteristics of the aptamer targeting the highly expressed proteins on the membrane surface of tumor cells, the conjugate delivered triptolide targeted to tumor cells and mediated endocytosis to reach the lysosome; based on the characteristics of the acidic environment of lysosomes, the acetal ester linking bond released intact triptolide in the lysosomal acidic environment, targeting and killing of tumor cells.Type: ApplicationFiled: September 14, 2023Publication date: March 21, 2024Inventors: Jun LU, Yun DENG, Yao CHEN, Jirui YANG, Yi ZUO, Xiao LI, Qing REN

Patent number: 7415055Abstract: Vertical cavity surface emitting lasers (VCSELs) and methods of making the same are described. The VCSELs include reliability-enhancing layers that perform specific functions at one or more critical locations within a VCSEL structure to reduce or prevent defect formation and migration that otherwise might degrade VCSEL performance, for example, by increasing optical absorption in the mirror stacks or by degrading the electro-optic properties of the active region. In particular, the reliability-enhancing layers are configured to perform one or more of the following functions within the VCSEL structure: gettering (i.e., removing defects or impurities from critical regions), strain balancing (i.e., compensating the lattice mismatch in the structure to minimize strain), and defect suppression (i.e., creating alloys that reduce the formation of defects during growth or post-growth activities).Type: GrantFiled: July 14, 2003Date of Patent: August 19, 2008Assignee: Avago Technologies Fiber IP Pte LtdInventors: Qing Deng, John Herniman

Patent number: 7356057Abstract: A vertical cavity surface emitting laser (VCSEL) module that is configured to operate in a wide temperature range without severely minimizing its lifetime or requiring excessive drive current. The VCSEL portion of the VCSEL module is tuned to operate efficiently at a higher than normal temperature. In addition to the VCSEL, the VCSEL module includes a heater and a temperature sensor that are used to maintain a particular minimum temperature that is within the efficient operation range of the VCSEL. By maintaining a temperature that is within the efficient operation range, the VCSEL module reduces the current required to operate the VCSEL and extends the overall lifetime of the VCSEL. The additional components of the VCSEL module do not interfere in any way with the signal quality produced by the VCSEL.Type: GrantFiled: October 28, 2003Date of Patent: April 8, 2008Assignee: Finisar CorporationInventors: Qing Deng, Ruldolf J.

Patent number: 6965628Abstract: A distributed feedback (“DFB”) laser featuring improved manufacturing yield and operational characteristics is disclosed. The present DFB laser includes a bottom confinement layer, an active region, and a top confinement layer disposed atop an n-doped substrate. A p-doped first top layer having a first index of refraction is disposed atop the top confinement layer. A grating is defined in the top surface of the first top layer, and a p-doped second top layer is overlaid on the grating. The two laser end facets are antireflectively coated. The grating is anisotropically etched to define a low kappa grating half and a high kappa grating half. Light waves produced in the active region interact with the grating and are biased toward the low kappa grating half that results in the majority of light signals passing through the end facet adjacent the low kappa grating half.Type: GrantFiled: October 30, 2002Date of Patent: November 15, 2005Assignee: Finisar CorporationInventors: Thomas Lenosky, Giorgio Giaretta, Qing Deng
