Patent number: 11661479Abstract: A dual-cure method for forming a solid polymeric structure is provided. An end-capped, imide-terminated prepolymer is combined with at least one photopolymerizable olefinic monomer, at least one photoinitiator, and a diamine, to form a curable resin composition, which, in a first step, is irradiated under conditions effective to polymerize the at least one olefinic monomer, thus forming a scaffold composed of the prepolymer and the polyolefin with the diamine trapped therein. The irradiated composition is then thermally treated at a temperature effective to cause a transimidization reaction to occur between the prepolymer and the diamine, thereby releasing the end caps of the prepolymer and providing the solid polymeric structure. A curable resin composition comprising an end-capped, imide-terminated prepolymer, at least one photopolymerizable olefinic monomer, at least one photoinitiator, and a diamine, is also provided, as are related methods of use.Type: GrantFiled: November 23, 2021Date of Patent: May 30, 2023Assignee: ZHEJIANG XUNSHI TECHNOLOGY CO..

Publication number: 20220171181Abstract: A fine-displacement adjusting device is constructed to have a first base portion and a second base portion spacedly encircled therewithin. The fine-displacement adjusting device further includes a first retractable element biased between the first and second base portions, and a first resilient element biased between the first and second base portions. The first retractable element is configured to extend and retract its length along a first axis to move the second base portion in a reciprocating manner. When the second base portion is moved by the first retractable element, the first resilient element moves the second base portion along the first axis to restore the second base portion. Therefore, the second base portion is fine-moved along the first axis in a reciprocating manner for adjusting the fine-displacement of an optical lens relative to an optical light source of a light engine in the first axis.Type: ApplicationFiled: July 2, 2021Publication date: June 2, 2022Applicant: ZHEJIANG XUNSHI TECHNOLOGY CO.
