Patent number: 11375600Abstract: A control device controls a plurality of light emitting devices, and includes: a controller that: collects device information from the light emitting devices that are repeatedly turned on and off in a lighting pattern, wherein a turn-on period and a turn-off period are defined within a cycle in the lighting pattern; determines an arrangement order of the light emitting devices based on the device information; calculates a start time at which each of the light emitting devices starts repetition of the lighting pattern using the arrangement order; and transmits lighting information including the start time to each of the light emitting devices and causes each of the light emitting devices to start the repetition of the lighting pattern.Type: GrantFiled: November 15, 2021Date of Patent: June 28, 2022Assignee: NAGOYA ELECTRIC WORKS CO., LTD.Inventors: Atsushi Tanaka, Hiroaki Sengoku, Koji Miyagawa

Patent number: 7610168Abstract: If a threshold discrimination is performed with variable Z=0 using discriminant analysis, that is useless unless know-how is accumulated through visual judgment and actual operation. A discriminant function is computed using a plurality of parameters which make pass/fail judgment factors and the results of that pass/fail judgment. With respect to the discriminant function, a histogram is generated for pass category and for fail category. Then, a threshold is determined based on the standard deviation in the individual categories so that an intended rate of flowout and rate of overcontrol will be obtained. The acceptability of pass/fail judgment objects is judged based on the threshold. Thus, the rate of flowout and the rate of overcontrol can be controlled as intended. Further, high-performance pass/fail judgment can be implemented without accumulating know-how.Type: GrantFiled: August 21, 2003Date of Patent: October 27, 2009Assignees: Toyota Jidosha Kabsuhki Kaisha, Nagoya Electric Works Co. Ltd.Inventors: Yasuo Isumi, Kou Hirano

Patent number: 7406152Abstract: In an inspection of an object of inspection with use of X-rays, X-rays are output from an X-ray source disposed fixedly into a range of a predetermined solid angle and, while the object of inspection is moved along a plane within the output range of the X-rays, the X-rays are detected, in positions included in the solid angle and at a plurality of revolved points around an axis oriented vertical to the plane along which the object of inspection is moved, with its detecting surface tilted down toward the axis. Thus, the object can be inspected based on the detected X-rays.Type: GrantFiled: November 29, 2005Date of Patent: July 29, 2008Assignee: Nagoya Electric Works Co., Ltd.Inventors: Atsushi Teramoto, Takayuki Murakoshi
