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

Patent number: 10421174Abstract: A pneumatic rotary tool includes a housing, a directional changeover mechanism, and a speed regulating mechanism. The housing includes a top body and a handle. The top body is fitted with a pneumatic motor. The handle defines a forward air channel, a reverse air channel, and an air supply passage. The air supply passage is controlled by a valve being operated by a trigger so that the air supply passage communicates with the forward and reverse air channels. The direction changeover mechanism is mounted in the top body along a transverse line and passes through the forward and reverse air channels for changing the rotational direction of the pneumatic motor. The speed regulating mechanism is mounted in the handle for adjusting the flow of compressed air entering the forward air channel. The tool can be operated conveniently to change the rotational direction and the output torque of the pneumatic motor.Type: GrantFiled: October 30, 2014Date of Patent: September 24, 2019Assignee: DE POAN PNEUMATIC CORP.Inventors: I-Tsung Wu, Yi-Wei Wen, Meng-Jen Chiu

Patent number: 10288504Abstract: The present invention provides an axial rotary type torque sensor comprising a planetary gear set disposed along a central axis between an input shaft and an output shaft. The input shaft drives the sun gear which meshes with planetary gears, and the planetary gears mesh with the ring gear of the planetary gear set to rotate along the circumference of the central axis. The ring gear is connected with a plurality of strip-like beams. At least one strain gauge is attached to the beams. One ending portion of the beam is fixed and the other ending portion is used for bearing a tangential force applied on the ring gear to generate a deformation at a rotation direction of a circumference. A strain gauge which senses the strain of the deformation used as a torque sensing value between the input shaft and the output shaft, thereby improving the poor sensing accuracy and sensitivity of the conventional torque sensors and solving the problem that the radial volume cannot be effectively reduced.Type: GrantFiled: November 13, 2017Date of Patent: May 14, 2019Assignee: PRODRIVES & MOTIONS CO., LTD.Inventors: Yueh-Yang Hu, Chih-Cheng Chou, Meng-Jen Chiu

Patent number: 10058983Abstract: A torque sensing device includes an idle wheel disposed between a force input shaft and a force output shaft, the idle wheel receives a tangential force from the force input shaft and the force output shaft to generate a counterforce as a loading, the center of the idle wheel is pivotally disposed on a positioning beam or a basis nearby, the positioning beam has a beam central line where a strain gauge installed. The positioning beam transforms the loading of the idle wheel along the beam central line to a normal force on the cross section of the positioning beam along the beam central line, the positioning beam generates a strain due to the normal force on the cross section of the positioning beam, the strain gauge detects the strain as the torsion sensing value of the output shaft on the region between the force input shaft and the force output shaft. A rotational driving tool is combined with the torque sensing device to improve the detecting precision of the torsion.Type: GrantFiled: January 8, 2016Date of Patent: August 28, 2018Assignee: PRODRIVES & MOTIONS CO., LTD.Inventors: Chia-Sheng Liang, Yuen-Yang Hu, Meng-Jen Chiu, Chu-Hsiang Tseng

Patent number: 9897499Abstract: A planet gear train based torque detector is provided with idler gears between an input shaft and an output shaft wherein a rotation of the input shaft rotates the idler gears which rotate the output shaft, and a force is applied to a tangent line between each idler gear and the input shaft; peripheral resilient members, each having a fixed first end and a second end for receiving force applied thereon by the revolution of idler gears; and at least one strain gauge, each attached on one resilient member for measuring a deformation at the resilient member due to the revolution of the idler gears. A torque between the input shaft and the output shaft is obtained by calculating the deformation. The resilient members parallel the input shaft.Type: GrantFiled: September 20, 2016Date of Patent: February 20, 2018Assignees: PRODRIVES & MOTIONS CO., LTD.Inventors: Chia-Sheng Liang, Yuen-Yang Hu, Meng-Jen Chiu
