Patent number: 11996772Abstract: The present invention provides a voltage control method for controlling a power supply. The voltage control method comprises the following steps: obtaining a present output voltage value associated with a present gain value; obtaining a predetermined output voltage value associated with a predetermined duty ratio; calculating a target gain value, corresponding to the predetermined duty ratio, according to a gain value formula; performing a weight calculation on the present gain value and the target gain value for generating a buffer gain value; and setting an output voltage command according to the buffer gain value. Wherein the buffer gain value is between the present gain value and the target gain value.Type: GrantFiled: December 27, 2021Date of Patent: May 28, 2024Assignee: Chroma ATE Inc.Inventors: Szu-Chieh Su, Wei-Chin Tseng, Chih-Hsien Wang, His-Ping Tsai, Wen-Chih Chen, Guei-Cheng Hu

Patent number: 9163054Abstract: The present invention establishes a fast and simple [F-18] FLT synthesis process. Solid extraction units are used for purification to achieve an equally high and constant radiochemical yield and purity in a short period of time. By using a separation method, the impurities are reduced successfully while the total synthesis time is shortened. The radiochemical purity and the corrected radiochemical yield are both high.Type: GrantFiled: September 20, 2011Date of Patent: October 20, 2015Assignee: INSTITUTE OF NUCLEAR ENERGY RESEARCH, ATOMIC ENERGY COUNCIL, Executive Yuan, R.O.C.Inventors: Li-Yuan Huang, Yen-Hung Tu, Wen-Chin Su, Jenn-Tzong Chen, Ting-Shien Duh, Wuu-Jyh Lin

Patent number: 8986652Abstract: The present invention provides a method of preparing [123I]Iodooctyl fenbufen amide with a radiochemical yield of 15%, a specific activity of 37 GBq/?mol and radiochemical purity of 95%. The present invention further provides a method of applying [123I]Iodooctyl fenbufen amide as tracer of single photon emission computer tomography (SPECT) to estimate the distribution of cyclooxygenase. By the binding characteristics of the iodine isotope-labeled compounds and the positive correlation of inflammation to tumor lesion, the present invention can estimate the tumor development and metastasis.Type: GrantFiled: February 1, 2013Date of Patent: March 24, 2015Assignee: National Tsing Hua UniversityInventors: Chung-Shan Yu, Ho-Lien Huang, Chun-Nan Yeh, Wei-Yuan Lee, Kang-Wei Chang, Ying-Cheng Huang, Kun-Ju Lin, Ching-Shiuann Yang, Shu-Fan Tien, Wen-Chin Su, Jenn-Tzong Chen, Wuu-Jyh Lin, Shiou-Shiow Farn

Patent number: 8691789Abstract: A tumor radiation probe of iodine-123 marker thymidine (FLT) analogue [123I]-IaraU is disclosed. Commercial available uridine is used as the raw material for the synthesis of the precursor. A radioactive iodine-123 is marked on an alkaline group of uridine to obtain [123I]-IaraU, which is distinguishable from [18F]-FLT marking 18F on a glycosyl group to obtain a novel tumor radiation probe. The marking procedures include mixing the marker precursor with Na [123I] solution, acetic acid and hydrogen peroxide solution, and the solution of chloroform and sodium hydroxide. The sonication time increases from 1 minute to 10 minutes, so that [123I]-IaraU has radiologically chemical purity of higher than 98% and radiological specific activity of not less than 0.196 GBq/umole, and the yield can increase from 8% to 40%. Its radioactive specific activity, yield and purity reach to the degree for the use in biological experiments, while reducing production cost.Type: GrantFiled: December 10, 2012Date of Patent: April 8, 2014Assignee: Institute of Nuclear Energy Research, Atomic Energy CouncilInventors: Jenn-Tzong Chen, Ho-Lien Huang, Jia-Rong Chen, Chung-Shan Yu, Wen-Chin Su, Ching-Shiuann Yang, Wuu-Jyh Lin
