Publication number: 20240168329Abstract: An electronic device including a first light emitting unit, a second light emitting unit, a first optical layer and a second optical layer is disclosed. The first light emitting unit emits a first light. The second light emitting unit emits a second light. At least one of the first light and the second light passes through the first optical layer. The second optical layer is overlapped with the first optical layer. The second optical layer is configured to scatter the first light emitted from the first light emitting unit.

Publication number: 20240139990Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.Type: ApplicationFiled: August 22, 2023Publication date: May 2, 2024Inventors: I-TSUNG WU, CHIA-SHENG LIANG, YU-CHE LIN, WEN-CHIN CHEN

Patent number: 11094514Abstract: A rotatable sputtering target has a target material, a back tube and a joint piece. The joint piece is disposed between the target material and the back tube. The joint piece has a compressible structure and an electrically and thermally conductive adhesive. Particularly, the compressible structure being a compressible blanket or a compressible sheet has multiple through holes and thus the electrically and thermally conductive adhesive is filled in the through holes and then directly formed between the target material and the back tube. Using the joint piece to joint the target material and the back tube not only maintains the joint strength but also elevates the tolerable power of the rotatable sputtering target, which can increase the sputtering efficiency.Type: GrantFiled: December 21, 2018Date of Patent: August 17, 2021Assignees: OUMEIDA APPLIED MATERIALS TECHNOLOGY CO., LTD., WELL AND SHINE PRECISION CO., LTD.Inventor: I-Sheng Wu

Publication number: 20110062020Abstract: A rotary target assembly has a cylindrical target and a cylindrical backing tube. A difference between an inner diameter of the cylindrical target and an outer diameter of the cylindrical backing tube substantially equals a yield strain of a target material multiplied by the inner diameter of the cylindrical target and multiplied by N, wherein N is between 1 and 10. The difference can be adjusted according to the target material, dimension of the cylindrical target, so the cylindrical target can be combined tightly with cylindrical backing tube. A resulting rotary target of the present invention has improved thermal and electrical conductivities.Type: ApplicationFiled: September 15, 2009Publication date: March 17, 2011Applicant: SOLAR APPLIED MATERIALS TECHNOLOGY CORPInventors: Chung-Han Wu, Wel-Hsun Hsu, I-Sheng Wu
