Patent number: 11199504Abstract: A shape inspection apparatus includes N illumination light sources, a line sensor camera, a measurement control unit, and a data processing unit. The measurement control unit controls the illumination light sources to modulate luminescence intensities at a frequency that is 1/N of a frequency of a scan rate of the line sensor camera, and to emit lights by sequentially repeating N different patterns of illumination intensity ratios. The data processing unit generates a first separated image and a second separated image based on a photographed image, generates a first mixing elimination image acquired by removing an unnecessary illumination component from the first separated image, and a second mixing elimination image acquired by removing an unnecessary illumination component from the second separated image, and calculates an inclination of the surface of the strip-shaped body based on a difference between the first mixing elimination image and the second mixing elimination image.Type: GrantFiled: December 7, 2018Date of Patent: December 14, 2021Assignee: NIPPON STEEL CORPORATIONInventors: Yusuke Konno, Takayuki Sonoda, Nobuhiro Furuya

Patent number: 10890441Abstract: A shape inspection apparatus for inspecting a strip-shaped body includes: a line sensor camera; a first illumination light source and a second illumination light source; a measurement control unit; and a data processing unit. The measurement control unit controls the lighting timings and light emission time periods as well as the line image acquisition timing based on a line speed so that overlapping of photographing ranges does not occur between a first line image acquired within a light emission time period of the first illumination light source and a second line image acquired within a light emission time period of the second illumination light source. The data processing unit calculates an inclination of the surface of the strip-shaped body based on a differential line image obtained based on the first line image and the second line image.Type: GrantFiled: November 27, 2018Date of Patent: January 12, 2021Assignee: NIPPON STEEL CORPORATIONInventors: Takayuki Sonoda, Nobuhiro Furuya

Patent number: 7406373Abstract: An electric power steering system for an automotive vehicle, including a steering torque detecting device which detects a steering torque of a steering shaft. An electric motor is provided to generate an assist torque for assisting a driver's steering effort required for steering the vehicle and a counter-assist torque for increasing the driver's steering effort. The assist torque and the counter-assist torque are applied to a steering mechanism. Additionally, a controller is provided to output a drive command to the electric motor in accordance with the detected steering torque. The drive command is for causing the electric motor to generate the counter-assist torque when the detected steering torque is a transitional torque.Type: GrantFiled: November 4, 2004Date of Patent: July 29, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Masahiro Kubota, Hiroshi Mouri, Tadashi Tamasho, Ryota Shirato, Takayuki Sonoda

Patent number: 7004280Abstract: In a multiplex power steering device for a wheeled vehicle, there is provided a control unit which includes a feedback computing part. The feedback computing part comprises an operating force estimating section that, by analyzing an output from a controlled system of actuators of a steering mechanism, estimates an output of the actuators, a disturbance estimating section that, by comparing a control signal actually fed to the actuators and the estimated output of the actuators, estimates a disturbance applied to the controlled system from the exterior, and a disturbance compensating section that adjusts the control signal in a manner to remove the estimated disturbance therefrom. The control unit calculates the control signal on the assumption that the actuators constitute a single actuator.Type: GrantFiled: November 21, 2003Date of Patent: February 28, 2006Assignee: Nissan Motor Co., Ltd.Inventors: Ryota Shirato, Hiroshi Mouri, Tadashi Tamasho, Masahiro Kubota, Takayuki Sonoda, Kiyotaka Shitamitsu
