Publication number: 20240136420Abstract: A thin film transistor includes a substrate, a semiconductor layer, a gate insulating layer, a gate, a source and a drain. The semiconductor layer is located above the substrate. The gate insulating layer is located above the semiconductor layer. The gate is located above the gate insulating layer and overlapping with the semiconductor layer. The gate includes a first portion, a second portion and a third portion. The first portion is extending along the surface of the gate insulating layer and directly in contact with the gate insulating layer. The second portion is separated from the gate insulating layer. Taking the surface of the gate insulating layer as a reference, the top surface of the second portion is higher than the top surface of the first portion. The third portion connects the first portion to the second portion. The source and the drain are electrically connected to the semiconductor layer.Type: ApplicationFiled: December 1, 2022Publication date: April 25, 2024Applicant: AUO CorporationInventors: Kuo-Jui Chang, Wen-Tai Chen, Chi-Sheng Chiang, Yu-Chuan Liao, Chien-Sen Weng, Ming-Wei Sun

Publication number: 20200188695Abstract: A beam shaping assembly for neutron capture therapy includes a beam inlet, a target having nuclear reaction with an incident proton beam from the beam inlet to produce neutrons forming a neutron beam, a moderator adjoining to the target, a reflector surrounding the moderator, a thermal neutron absorber adjoining to the moderator, a radiation shield arranged inside the beam shaping assembly and a beam outlet. The material of the moderator is subjected to a powder sintering process using a powder sintering device so as to change powders or a power compact into blocks. The reflector leads the neutrons deviated from the main axis back. The thermal neutron absorber is used for absorbing thermal neutrons so as to avoid overdosing in superficial normal tissue during therapy. The radiation shield is used for shielding leaking neutrons and photons so as to reduce dose of the normal tissue not exposed to irradiation.Type: ApplicationFiled: December 26, 2019Publication date: June 18, 2020Inventors: Yuan-hao LIU, Wei-Iin CHEN, Pei-yi LEE, Ming-chuan CHANG, Wenyu XU

Patent number: 8961971Abstract: This invention relates to bispecific antibodies having combinations of linker and hinge sequences to create linker-hinge interface domains with biological significance. Such linker-hinge interface domains covalently join two molecules, maintain the biological activities of linked molecules (target binding), stabilize the biological characteristics of new molecule (solubility and 4° C. stability), maintain the chemical, biochemical and physical properties (cytotoxicity) of the linked molecules, and modulate the biological characteristics of the linked molecules (activating T-lymphocytes without significant sign of proliferations). Both linker (GGGGS) and hinge (CPPCP) sequences are required to establish functional linker-hinge interface domains as deletion of any of the component resulted in significant lost of T-lymphocyte mediated activity.Type: GrantFiled: December 19, 2012Date of Patent: February 24, 2015Assignees: Development Center for Biotechnology, DCB-USA LLCInventors: Yu-Shen Hsu, Show-Shan Sheu, Ming-I Chang, Ming-Chuan Chang, Ta-Tung Yuan

Publication number: 20050158326Abstract: Disclosed is a composition for reducing virus infection rates in crustaceans, which can be applied in prevention and/or treatment of viral infection in crustaceans, and therefore improves the survival rate. The composition comprises at least one of the antibodies that can bind specifically to virus, and the antibodies are selected from the group consisting of monoclonal antibody, phage display antibody and antibody produced by a recombinant organism. The monoclonal antibodies can be produced in a large scale from hybridoma cells with a bioreactor or by injecting into the abdominal cavities of mice. Alternatively, two other highly specific antibodies can be produced from phage clones and recombinant organisms. The composition can be used in the forms of therapeutic medicines, nutritious or feeding supplements in addition to feeds. Also, the composition can be used in an aqueous solution to expose the crustaceans to fulfill the needs of treatment and/or prevention of viral infection in crustaceans.Type: ApplicationFiled: December 20, 2004Publication date: July 21, 2005Inventors: Chin-Yu Chen, Tai-Hsin Yang, Chan-Yen Tsai, Woan-Jiun Swei, Ming-Chuan Chang
