Patent number: 11933752Abstract: A gas sensor includes: a gas-sensitive body layer disposed above a substrate and including a metal oxide layer; a first electrode on the gas-sensitive body layer; and a second electrode on the gas-sensitive body layer, being apart from the first electrode by a gap. The gas-sensitive body layer has a resistance change characteristic that reversibly transitions to a high-resistance state and a low-resistance state on basis of a voltage applied across the first electrode and the second electrode. At least a part of the gas-sensitive body layer is exposed to the gap. The gas-sensitive body layer has a resistance that decreases when gas containing a hydrogen atom is in contact with the second electrode.Type: GrantFiled: July 23, 2019Date of Patent: March 19, 2024Assignee: NUVOTON TECHNOLOGY CORPORATION JAPANInventors: Satoru Fujii, Zhiqiang Wei, Kazunari Homma, Shinichi Yoneda, Yasuhisa Naito, Hisashi Shima, Hiroyuki Akinaga

Patent number: 11058386Abstract: According to one embodiment, a medical image diagnosis system includes a plurality of devices, operating circuitry, processing circuitry, and a display. The plurality of devices is to be inserted into a body of an object. The operating circuitry operates at least one of the devices. The processing circuitry obtains a medical image of the object and specifies a device being operated based on movement of the device in the medical image when the device is being operated by the operating circuitry. The display identifiably displays a device to be operated by the operating circuitry based on a result of specification by the processing circuitry.Type: GrantFiled: November 15, 2016Date of Patent: July 13, 2021Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Kazunari Shima, Hajime Yoshida, Kazuhiro Taniyama, Satoru Ohishi, Takeo Matsuzaki

Patent number: 10973473Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray movable diaphragm and processing circuitry. The X-ray movable diaphragm limits an irradiation field of an X-ray. The processing circuitry sets an FOV size related to the irradiation field, sets a virtual field of view having the FOV size, the virtual field of view being able to include an outside region of an X-ray detection region and at least a part of the X-ray detection region, and controls the X-ray movable diaphragm so as to apply the X-ray to a common region between the virtual field of view and the X-ray detection region.Type: GrantFiled: June 21, 2018Date of Patent: April 13, 2021Assignee: Canon Medical Systems CorporationInventors: Yoshimasa Kobayashi, Kazunari Shima, Hayato Kasaoka, Takahiro Tanaka, Hisanori Kato, Nobuo Kobayashi, Norimitsu Kosugi

Patent number: 9693741Abstract: A mammographic apparatus that includes X-ray detectors configured to detect X-rays entering the X-ray detectors, and attached to a holding-arm placed on a floor. The mammographic apparatus further includes circuitry configured to move the X-ray detectors between a scanning position and a waiting position. The X-ray detectors in the scanning position face an X-ray tube that generates X-rays across a breast-table, and the X-ray detectors in the waiting position are closer to the holding-arm than are the X-ray detectors in the scanning position.Type: GrantFiled: December 11, 2014Date of Patent: July 4, 2017Assignee: Toshiba Medical Systems CorporationInventors: Yoshimasa Kobayashi, Haruki Iwai, Rie Ochiai, Koichiro Watanabe, Kazunari Shima

Publication number: 20160073998Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an radiography system radiographs the subject, a support frame movably supports the radiography system, a communication circuitry obtains skin dose information of the subject, a processing circuitry decides the irradiation range at the movement destination of the radiography system based on the skin doses of the subject, a control circuitry controls the support frame to move the radiography system to an radiography position corresponding to the decided irradiation range at the movement destination. The irradiation range at the movement destination comes close to the irradiation range on the subject immediately before the movement, and a skin dose corresponding to the irradiation range at the movement destination is less than a threshold.Type: ApplicationFiled: September 4, 2015Publication date: March 17, 2016Applicants: KABUSHIKI KAISHA TOSHIBA, Toshiba Medical Systems CorporationInventors: Kazunari SHIMA, Masanori MATSUMOTO, Yoshimasa KOBAYASHI, Yusuke NARABU
