Publication number: 20180112592Abstract: A valve control device controls a valve drive mechanism on the basis of a degree-of-opening signal for a valve and a startup signal for an engine, and includes: a drive signal generating unit that, when it is determined on the basis of the startup signal that the engine is stated, generates a test drive signal for test-driving the valve before the generation of a normal drive signal associated with normal driving of the valve; and an abnormality determining unit that, on the basis of the degree-of-opening signal during the test driving, determines whether or not an abnormality has occurred in the drive mechanism. The drive signal generating unit stops generating the test drive signal and the normal drive signal when the abnormality determining unit determines that the abnormality has occurred in the drive mechanism.Type: ApplicationFiled: March 24, 2016Publication date: April 26, 2018Applicants: KEIHIN CORPORATION, Honda Motor Co., Ltd.Inventors: Sachio HOJO, Youichiro SHIKINE, Tetsuo YAMASHITA, Shigeki YOSHITAKE, Kensuke YAMAMOTO, Akihito INOUE

Patent number: 9721861Abstract: A semiconductor device includes a semiconductor element and a ceramic circuit substrate on which the semiconductor element is mounted. The ceramic circuit substrate includes a ceramic substrate having one surface and the other surface facing each other, a metal circuit board joined to the one surface of the ceramic substrate and electrically connected to the semiconductor element, and a metal heat-dissipation plate joined to the other surface of the ceramic substrate. The metal circuit board is greater in thickness than the metal heat-dissipation plate. A surface of the metal heat-dissipation plate on a side opposite to the ceramic substrate is larger in area than a surface of the metal circuit board on a side opposite to the ceramic substrate. Thereby, a semiconductor device capable of suppressing warpage of the ceramic substrate can be achieved.Type: GrantFiled: April 15, 2015Date of Patent: August 1, 2017Assignee: Mitsubishi Electric CorporationInventors: Yoshitaka Otsubo, Takuya Takahashi, Masaomi Miyazawa, Tetsuo Yamashita, Tomohiro Hieda, Mituharu Tabata

Publication number: 20170123063Abstract: A distance measuring device includes a first measurer, a second distance measurer, and circuitry. The first distance measurer measures a distance to a target object; and outputs first distance information indicating a measured distance when the distance measurement is performed under a condition that satisfies a distance measurement condition, but outputs the first distance information indicating a predetermined value when the distance measurement is performed under a condition that does not satisfy the distance measurement condition. The second distance measurer measures a distance to the target object and outputs second distance information indicating the measured distance. When the first distance information indicates the predetermined value and the second distance information satisfies a predetermined condition, the circuitry makes alteration such that the distance measurement condition is relaxed.Type: ApplicationFiled: October 25, 2016Publication date: May 4, 2017Inventors: Tetsuo YAMASHITA, Satoshi SAWAGUCHI, Fumiko SAKOH, Soichiro YOKOTA, Kiichiroh SAITOH, Tadashi NAKAMURA
