Patent number: 10960555Abstract: The present invention provides a robot arm. The robot arm is for forking a substrate, and includes: a substrate fork and vacuum cups. The substrate fork includes parallel spaced prongs, and an upper surface of each prong is provided with vacuum cups spaced along an extending direction of the prong; and vacuum cups on two prongs at outermost sides of the substrate fork are scratch-resistant vacuum cups, and a top face and a side face of each scratch-resistant vacuum cup are connected through an arc-shaped surface. By setting the top face of the scratch-resistant vacuum cup connected to the side face through the arc-shaped surface, when the substrate is bent with the gravity, the contact area between the substrate and the scratch-resistant vacuum cup can be increased, to improve the friction therebetween, prevent the substrate from being scratched in a transportation process, and ensure the security of substrate transportation.Type: GrantFiled: November 26, 2018Date of Patent: March 30, 2021Assignee: Wuhan China Star Optoelectronics Technology Co., Ltd.Inventor: Guangyu Cai

Patent number: 6093866Abstract: An alkylation catalyst comprises from 50 to 70 wt % of hydrogen type ZSM-SM-11 co-crystaline zeolite containing rare earth element and the rest amount of porous inorganic oxide matrix material. The zeolite has particular chemical composition and X-ray diffraction lines. This catalyst has higher activity, selectivity and stability in alkylation process than that of the prior art. With this catalyst the process for preparing ethyl benzene by alkylation of benzene with ethylene has higher ethylene conversion and ethyl benzene selectivity.Type: GrantFiled: June 23, 1997Date of Patent: July 25, 2000Assignees: China Petro-Chemical Corporation, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Fushun Petrochemical Company of SinopecInventors: Qingxia Wang, Shurong Zhang, Guangyu Cai, Feng Li, Longya Xu, Zuxian Huang, Yuying Li
