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: 20190118348Abstract: A pair of pliers has a main body with a first lever, a second lever pivotally connected to the first lever, and a wire stripping mechanism. The wire stripping mechanism is mounted to the main body and has two stripping assemblies and an elastic unit. Each one of the two stripping assemblies has a clamping mount, a pinching component, a pivoting pole, and a linkage set. The clamping mount is pivotally connected to the main body. The pinching component is pivotally connected to the clamping mount via the pivoting pole. The linkage set has a linkage unit pivotally connected to the pinching component and one of the first lever and the second lever. The elastic unit is connected to two pivoting poles of the two stripping assemblies. The two stripping assemblies are driven by the first lever and the second lever.Type: ApplicationFiled: August 21, 2018Publication date: April 25, 2019Inventor: Ying-Ju LIN

Publication number: 20180156322Abstract: A ball screw with a support device includes: a screw; a nut unit movably mounted on the screw; a support device including: a first support seat and a second support seat which are movably mounted on the screw and located at two sides of the nut unit; and a speed control device capable of presetting a speed of the nut unit and the first and second support seats, wherein the speed of the nut unit is VNT, the speed of the first and second support seats is VSUP, and they satisfy the relation: 0<VSUP/VNT<½. When the two ends of the screw are used as a fixing end and a support end, respectively, the ball screw can have an optimized critical rotation speed, which consequently improves the work efficiency of the ball screw.Type: ApplicationFiled: December 1, 2016Publication date: June 7, 2018Inventors: Szu-Wei YU, Ying-Ju LIN, Chieh-Ping WANG

Publication number: 20180053580Abstract: Provided is a polyimide insulation coating, which is prepared by reacting a diacid anhydride compound represented by Formula (I) with a diamine compound represented by Formula (II). By adopting the specific diacid anhydride compound and the specific diamine compound, the synthesized polyimide insulation coating can have a dielectric constant less than 3. Accordingly, the enameled wire having an insulation layer formed from the polyimide insulation coating would not readily produce partial discharge, thereby avoiding the penetrating short-circuit and the damage to the motor.Type: ApplicationFiled: August 16, 2016Publication date: February 22, 2018Inventors: WEI-FANG SU, MING-HAN CHIANG, CHI-FENG HUNG, HUI-JU TSAI, YA-TING CHANG, YING-JU LIN, TING-I LU

Patent number: 9360096Abstract: A ball screw with support devices includes a nut base having two sides equipped with the support devices for preventing the screw from deflection. Two runner structures are provided near two ends of the screw. The runner structure includes a driving wheel and a driven wheel having different diameters and concentrically installed. The nut base is connected to the driving wheel via an active connecting element for driving the driving wheel to rotate. The driven wheel moves with the driving wheel and is connected to the support devices via passive connecting elements so that the support devices and the nut displace synchronously. By controlling a diameter ratio between the driving and driven wheels, the nut and the support devices displace with proportional speeds, thereby allowing the support devices to always stay at the two sides of the nut as designed and provide reliable support.Type: GrantFiled: November 28, 2014Date of Patent: June 7, 2016Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Ying-Ju Lin, Hung-Chih Hsu
