Patent number: 11326245Abstract: A mask includes a mask body and at least one sub-mask provided on the mask body. The sub-mask includes an evaporation zone and a shield portion. The shield portion is provided with at least one groove in a thickness direction of the sub-mask. The groove has a depth smaller than a thickness of the mask body. Since the shield portion is provided with the groove, and a single groove has a depth smaller than the thickness of the mask body, it not only ensures that there is no pixel evaporated onto a substrate at the shield portion, but also reduces the thickness of the shield portion, thereby reduces weight thereof, lowers the weight difference between the shield portion and the evaporation zone and reduces the stress concentration on the shield portion, resulting in that the mask body is evenly stressed during tensioning.Type: GrantFiled: May 29, 2019Date of Patent: May 10, 2022Assignee: KUNSHAN GO-VISIONOX OPTO-ELECTRONICS CO., LTD.Inventors: Mengfan Wang, Guobing Wang, Qian Su, Jinku Li, Menghua Kang, Xin Ye

Patent number: 11299450Abstract: A system and a process for co-producing dimethyl carbonate and ethylene glycol. The system comprises an interconnected ethylene carbonate preparation unit and an ethylene carbonate alcoholysis unit. The ethylene carbonate preparation unit comprises a fixed bed reactor and a light-component stripping column connected to each other. The fixed bed reactor is filled with a supported ionic liquid catalyst. The process comprises the steps of: reacting carbon dioxide and ethylene oxide as raw materials in the fixed bed reactor to produce ethylene carbonate, purifying the ethylene carbonate and then mixing it with an alcoholysis reaction catalyst, and reacting the mixture with methanol in a reactive distillation tower, producing dimethyl carbonate and ethylene glycol. The process increases the conversion rate of ethylene oxide and avoids the need for a process of separating conventional homogeneous catalysts from ethylene carbonate, thereby reducing process energy consumption and simplifying process procedures.Type: GrantFiled: September 14, 2017Date of Patent: April 12, 2022Assignee: INSTITUTE OF PROCESS ENGINEERING, CHINESE ACADEMY OF SCIENCESInventors: Weiguo Cheng, Li Dong, Qian Su, Songsong Chen, Junping Zhang, Suojiang Zhang
