Patent number: 11529730Abstract: A robot system includes a robot controller and an object robot including a first storage part storing a hardware identifier, individual discrimination data, and device specific data including an individual difference parameter. The same hardware identifier is assigned to the object robot having the same mechanism. The robot controller includes a second storage part storing common configuration information corresponding to the hardware identifier and the individual discrimination data and the individual difference parameter of the object robot, and a control part configured, in a case that the hardware identifier corresponding to the common configuration information stored in the second storage part and the hardware identifier assigned to the object robot are collated and matched with each other, to create hardware definition information of the object robot based on the common configuration information stored in the second storage part and the individual difference parameter read from the first storage part.Type: GrantFiled: April 27, 2020Date of Patent: December 20, 2022Assignee: NIDEC SANKYO CORPORATIONInventors: Hirokatsu Okumura, Jun Otsuji, Tetsuya Inomata

Patent number: 11130232Abstract: A robot system may include a robot controller; and a target robot. The target robot may include a first memory to store device specific data including individual identification data; and an individual difference parameter unique to the target robot. The robot controller may include a second memory structured to store the individual identification data and the individual difference parameter of the target robot connected to the robot controller; and a controller to control the target robot on the basis of model configuration information the individual difference parameter stored in the second memory. The controller may check the individual identification data read from the first memory unit against the individual identification data stored in the second memory unit and, in accordance with a checking result, update the individual difference parameter stored in the second memory unit with the individual difference parameter read from the first memory unit.Type: GrantFiled: December 18, 2018Date of Patent: September 28, 2021Assignee: NIDEC SANKYO CORPORATIONInventors: Hirokatsu Okumura, Jun Otsuji, Tetsuya Inomata

Patent number: 10345827Abstract: A motor control device may include a position command output means, a first subtraction means that calculates and outputs a position deviation, a position control means, a second subtraction means that calculates and outputs a position deviation, a speed control means that outputs a torque command, a limiter limits the level of the torque command, a motor drive means, and a voltage fluctuation detection means. When the voltage fluctuation detection means detects that the voltage of said power source has dropped below a predetermined reference level, either the position command output means varies the position command so as to reduce the rotational speed of the motor and/or said position control means limits said speed command to be output.Type: GrantFiled: August 6, 2011Date of Patent: July 9, 2019Assignee: NIDEC SANKYO CORPORATIONInventors: Jun Otsuji, Akihiro Ito, Hirokazu Watanabe, Hideyuki Odagiri

Patent number: 6818974Abstract: A semiconductor device which has a preferable construction for downsizing, in which chip part(s) and a cap are not short-circuited, is provided. The semiconductor device includes: a substrate having a first surface with a cavity and a second surface opposite to the first surface; a semiconductor chip arranged in the cavity; a chip part mounted on the second surface of the substrate; a heat sink which is mounted on the second surface of the substrate and transfers heat liberated from the chip; a cap which is fitted to the substrate, covers the second surface of the substrate, and is joined to the heat sink; and an insulator provided between the cap and the chip part. By providing the insulator, short-circuiting of the chip part and the cap is prevented. Consequently, a distance between the cap and chip part can be shortened to downsize the size of semiconductor device.Type: GrantFiled: January 30, 2003Date of Patent: November 16, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuo Yokoyama, Shigeki Kageyama, Jun Otsuji
