Publication number: 20210190678Abstract: One point on a surface of a qualified article is measured in advance by a color sensor without contact, and a qualification reference value is set based on an output value thereof. Thereafter, one point on a surface of an inspection target of same design specifications as the qualified article is measured by the color sensor without contact, and an output value thereof is compared with the qualification reference value, and qualification/failure is judged. Because qualification/failure can be carried out without contacting an inspection target in this way, application to a high-speed production line is possible.Type: ApplicationFiled: October 25, 2018Publication date: June 24, 2021Inventors: Toshiya Tsuji, Shoichi Yamamoto, Yuji Kobayashi, Toshio Sugibayashi, Shun Yoshida

Patent number: 8418669Abstract: In an internal combustion engine having a pair of balancer shafts (53, 54), an engine torque is transmitted from a crank gear (28) to an oil pump gear (74) on a drive shaft (73) of an oil pump (71) via a first idler gear (84) and the first balancer shaft gear (64). The engine torque is also transmitted to a fuel pump (72) from the crank gear to a fuel pump gear (78) via the first idler gear and a second idler gear (86), and to the second balancer shaft gear (67) via the first idler gear and second idler gear. Alternatively, the engine torque may be transmitted to the fuel pump from the crank gear to the fuel pump gear via the first idler gear, second balancer shaft gear and second idler gear. As the oil pump gear is actuated by the crank gear via the first idler gear, the oil pump gear is not subjected to the loading caused by the balancer shaft, and hence can be made of a compact and light-weight gear.Type: GrantFiled: February 10, 2011Date of Patent: April 16, 2013Assignee: Honda Motor Co., Ltd.Inventors: Goichi Katayama, Yoshihiro Fujiyoshi, Yutaka Tajima, Shoichi Yamamoto
