Patent number: 11602804Abstract: The present invention discloses that a multi-laser cutting method and system, which is applied to a substrate to form a primary substrate having a pattern of rounded corners and a line, the throughput could be improved because CO2 laser cannot cut the round corner at the high speed, but the substrate strength could be kept due to the high cutting quality of the lines by CO2 laser. The poor quality of the cutting edges of the round corners will not affect on the substrate strength but the round corner cutting by the second laser unit will speed up the cutting process. The present invention applies the method by the 2 different laser machines to balance the throughput. Because at the same speed, for example 150 mm/sec, the cycle time per 1 substrate will be different due to the different length of the cutting lines.Type: GrantFiled: April 29, 2020Date of Patent: March 14, 2023Assignee: TOPAPEX ENVIRONMENT PROTECTION ENERGY CO., LTDInventors: Hung-Tu Lu, Alexander Naumov, Vladimir Kondratenko

Patent number: 11247947Abstract: A method is provided to purify [F-18]FEONM under a high pressure. The synthesis processes of [F-18]FEONM are integrated. An isolation process of non-toxic radio-high performance liquid chromatography (radio-HPLC) is used to purify the crude product. The method integrates a convention [F-18]FDG synthesizer and a novel radio-HPLC system together in a heat chamber. After radiofluorinating the precursor, the reaction product is purified with an alumina solid-phase column in advance to obtain the crude product while fluorine-18 is removed. Then, diphenyl semipreparative HPLC column is used for a final purification. A non-toxic solvent is used for mobile-phase eluting to remove the unreacted precursor and the phase-transfer solvent. The radiofluorination has a reaction yield about 50 percent (%). The method has an uncorrected radiochemical yield of 10˜20%. Both of the radio-HPLC and the radio-thin layer chromatography (radio-TLC) have radiochemical purity higher than 95%.Type: GrantFiled: January 4, 2021Date of Patent: February 15, 2022Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Yean-Hung Tu, Li-Yuan Huang, Jenn-Tzong Chen, Tsai-Yueh Luo, Shiou-Shiow Farn, Wuu-Jyh Lin
