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: 8914602Abstract: A controller and a method of updating parameters on the same. The controller includes an embedded non-volatile memory, a programming circuit, an embedded SRAM, a MCU (Micro Computer Unit), and a memory controller. The embedded non-volatile memory has a program code block for storing program codes to be executed by the MCU, and a data block for storing the parameters. The MCU writes the parameters into the data block of the flash memory through the memory controller, or reads data in the data block of the non-volatile memory through the memory controller. Because the controller does not need to employ an external EEPROM, the cost can be reduced and the speed for accessing the parameters can be increased.Type: GrantFiled: November 8, 2006Date of Patent: December 16, 2014Assignee: Realtek Semiconductor Corp.Inventors: Wen-Jui Lin, Hsien-Chun Chang, Yi-Shu Chang, Wen-Che Wu
