Patent number: 11940060Abstract: The present invention provides a seal ring structure, which comprises a seal ring member. The seal ring member includes a first ring opening on one side and a second ring opening on the other. A periphery of the first ring opening includes a plurality of leak grooves. When the seal ring member and the valve ball squeeze each other, the plurality of leak grooves can reduce the torque required to rotate the valve ball. A leak-groove length of the plurality of leak grooves is smaller than a seal-ring-member length of the seal ring member. The plurality of leak grooves do not penetrate the seal ring member for avoiding leakage of fluid.Type: GrantFiled: August 5, 2022Date of Patent: March 26, 2024Assignee: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTREInventors: Ching-An Lin, Chin-Kang Chen, Chia-Ho Cheng

Patent number: 11486695Abstract: The present invention provides a measurement device for grinding wheel. One or more thickness measurement device is disposed slidably on a platform. A spinning device is disposed on the platform. A grinding wheel is fixed on the spinning device. The spinning shaft spins the grinding wheel. The one or more thickness measurement device measures the flatness condition of the grinding wheel. Furthermore, according to the present invention, a diameter measurement device is disposed inside the platform and measures the roundness of the outer periphery of the grinding wheel. Since the structure can be disassembled easily, the whole measurement device for grinding wheel can be carried conveniently. In addition, measurements can be performed by users on the site where the grinding wheel is located for real-timely understanding the real size and wear condition of grinding wheel.Type: GrantFiled: December 4, 2020Date of Patent: November 1, 2022Assignee: Metal Industries Research & Development CentreInventors: Chin-Kang Chen, Ching-An Lin, Chia-Ho Cheng, Sung-Liang Hsieh, Chih-Hsin Chang
