Patent number: 11945004Abstract: A semiconductor manufacturing equipment cleaning system has a multi-station cleaning and inspection system. Within semiconductor manufacturing equipment cleaning system, a tray cleaning station uses a first rotating brush passing over a first surface of a carrier and possibly semiconductor die, and a second rotating brush passing over a second surface of the carrier and semiconductor die opposite the first surface of the carrier and semiconductor die. Debris and contaminants dislodged from the first surface and second surface of the carrier by the first rotating brush and second rotating brush are removed under vacuum suction. A conveyor transports the carrier through the multi-station cleaning and inspection system. The first rotating brush and second rotating brush move in tandem across the first surface and second surface of the carrier. Air pressure is injected across the first rotating brush and second rotating brush to further remove debris and contaminants.Type: GrantFiled: November 11, 2021Date of Patent: April 2, 2024Assignee: UTAC Headquarters Pte. Ltd.Inventors: Hua Hong Tan, Wing Keung Lam, Zong Xiang Cai, Wei Ming Xian, Yao Hong Wu, Tao Hu

Patent number: 11649714Abstract: A method for predicting and optimizing an ROP for oil and gas drilling based on Bayesian optimization includes: acquiring raw drilling data according to a preset sampling period, constructing an initial sample data set based on the raw drilling data, constructing an ROP prediction model based on the initial sample data set, and predicting an ROP at a next sample point through a Gaussian process regression based on the ROP prediction model. The present invention realizes rapid analysis of historical drilling data and accurate prediction of an ROP range at a sample point in a feasible domain. The method can obtain an optimized ROP and an optimized engineering parameter through Bayesian optimization, and obtain an engineering parameter corresponding to an optimal ROP. The method has few restrictions on the drilling engineering parameter and the raw formation parameter, improves prediction accuracy, and avoids the problem of blurred parameter value boundaries.Type: GrantFiled: April 6, 2022Date of Patent: May 16, 2023Assignee: Southwest Petroleum UniversityInventors: Yan Chen, Yuchuan An, Xiangchao Shi, Yu Yi, Yang Wang, Zhicheng Li, Gaocheng Feng, Yangbing Li, Ping Li, Yuan Zhong, Ming Xian, Hu Deng, Yuming Wang, Yuehao Liu

Patent number: 10702089Abstract: An egg cooking system includes two woks and each of the woks receives oil from an oil supply member. A support member is driven by a driving unit to allow one egg to be put in the at least one standby portion and the egg is pressed by the pressing member. A cracking member cracks the egg and the pressing unit moves toward the direction that the egg is located so that a claw is opened, and the egg flows into one of the woks. The egg is cooked for a pre-set time, and is dropped into the other wok to be cooked. The cooked egg is then dropped to a plate. The pressing unit presses the egg shell of the egg to further open the claw, and the egg shell drops into a garbage can.Type: GrantFiled: June 28, 2018Date of Patent: July 7, 2020Assignee: Lunghwa University of Science and TechnologyInventors: Lian-Wang Lee, Hsiu-Chao Lee, Bo-Xu Su, Ming-Xian Cai, Te-Sheng Wei, Tsung-Hsin Lee
