Publication number: 20240131538Abstract: An annular airflow regulating apparatus includes a cup-shaped element and an adjustment element. The cup-shaped element has a bowl and a bottom, integrated to form a first chamber. The bottom has a tapered channel parallel to an axis and penetrating through the bottom. A ring-shaped groove is disposed between the tapered channel and the bottom. The ring-shaped groove has an annular plane perpendicular to the axis. The adjustment element, having a tapered portion and second holes, is movably disposed in the cup-shaped element. The tapered portion protrudes into the tapered channel A tapered annular gap is formed between the tapered portion and the tapered channel. When the adjustment element is moved with respect to the cup-shaped element, a width of the tapered annular gap is varied, and thereupon a flow rate and velocity of the process gas would be varied accordingly.Type: ApplicationFiled: December 8, 2022Publication date: April 25, 2024Inventors: CHEN-CHUNG DU, Ming-Jyh Chang, Chang-Yi Chen, Ming-Hau Tsai, Ko-Chieh chao, Yi-Wei Lin

Patent number: 11934027Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.Type: GrantFiled: June 21, 2022Date of Patent: March 19, 2024Assignee: TDK TAIWAN CORP.Inventors: Chao-Chang Hu, Chih-Wei Weng, Chia-Che Wu, Chien-Yu Kao, Hsiao-Hsin Hu, He-Ling Chang, Chao-Hsi Wang, Chen-Hsien Fan, Che-Wei Chang, Mao-Gen Jian, Sung-Mao Tsai, Wei-Jhe Shen, Yung-Ping Yang, Sin-Hong Lin, Tzu-Yu Chang, Sin-Jhong Song, Shang-Yu Hsu, Meng-Ting Lin, Shih-Wei Hung, Yu-Huai Liao, Mao-Kuo Hsu, Hsueh-Ju Lu, Ching-Chieh Huang, Chih-Wen Chiang, Yu-Chiao Lo, Ying-Jen Wang, Shu-Shan Chen, Che-Hsiang Chiu

Publication number: 20230217547Abstract: A base station management device is provided in the invention. The base station management device includes a Non-Real Time (Non-RT) Radio-Access-Network Intelligent Controller (RIC) and a management device. The Non-RT RIC communicates with applications through a first communication interface. The management device manages a plurality of base stations, communicates with the Non-RT RIC through a second communication interface, and registers a first application and a second application through the Non-RT RIC. The management device detects the plurality of base stations through the first application to determine whether to update the parameter information of the plurality of base stations through the second application.Type: ApplicationFiled: March 13, 2023Publication date: July 6, 2023Inventors: Chih-Wei SU, Chen-chieh TSAI

Patent number: 6364193Abstract: An electric nailing tool comprises a housing, a nail magazine for supplying nails, a spout attached to the nail magazine and having a passage communicated with the housing, a solenoid set, and a hammer. The solenoid set comprises at least two solenoids having a common through-hole for receiving the hammer. A percussion member is securely attached to an end of the hammer to move therewith, thereby driving a nail in the passage out of the spout upon percussion movement of the hammer. The solenoids are energized and de-energized in sequence to move the hammer back and forth along the common through-hole of the solenoids, thereby providing at least two impacting motions by the percussion member to the nail in the passage.Type: GrantFiled: May 29, 2001Date of Patent: April 2, 2002Assignee: Acumen Power Tools Corp.Inventor: Chen-Chieh Tsai
