Publication number: 20200146701Abstract: Provided is an intraluminal foreign object capturing tool with which it is possible to cause a capturing member for capturing a foreign object to expand to an appropriate diameter. The foreign object capturing tool, in order to capture a foreign object in a lumen, includes: a core wire; a capturing member which is disposed movably outside the core wire, has a farthest tip-end which is movement-regulated at a predetermined position of the core wire, and expands in diameter by contracting axially; a tubular member which is disposed outside the core wire on a base end side of the capturing member, and which regulates movement of capturing member on the base end side; and control members which are disposed outside the core wire and inside the capturing member, and which regulate the amount of axial contraction of the capturing member. As the tubular member and the core wire are moved relative to each other, the capturing member contracts axially by a length regulated by the control member and expands in diameter.Type: ApplicationFiled: August 17, 2018Publication date: May 14, 2020Inventors: Toshiyuki IRIE, Kazutaka NANAUMI, Shuji ISOZAKI

Patent number: 8861826Abstract: A view image of high time resolution acquired in an imaging process of X-ray CT is displayed. In this display, by subtracting a background image obtained by forward projection calculation of a CT image from the view image, background is removed from the view image, and only a focused site is imaged. A transmission image of the focused site showing high display contrast and not easily influenced by a motion artifact can be thereby obtained. Thereby, in an X-ray CT device for diagnostic imaging, degradation of diagnostic ability due to motion artifacts can be prevented.Type: GrantFiled: August 4, 2010Date of Patent: October 14, 2014Assignee: Hitachi Medical CorporationInventors: Toshiyuki Irie, Hironori Ueki, Keisuke Yamakawa

Patent number: 8508873Abstract: A water-resistant structure of a lens barrel includes a sealing member that seals an annular gap between inner and outer annular members, wherein the sealing member is positioned in a vicinity of an open end of the outer annular member and is fixed to one of the inner and outer annular members to be slidable on the other of the inner and outer annular members, and a drain groove formed on the inner annular member and positioned alongside the sealing member at a position closer to the open end of the outer annular member than the sealing member. Furthermore, a frictional resistance of a first sealing member produced between a secondary annular member and a manually-rotatable annular members is greater than a frictional resistance of the second sealing member that urges one of two of the manually-rotatable annular members to follow a rotation of the other thereof when rotated.Type: GrantFiled: February 23, 2010Date of Patent: August 13, 2013Assignee: Pentax Ricoh Imaging Company, Ltd.Inventors: Makoto Iikawa, Yuji Kogure, Yuzo Minowa, Toshiyuki Irie

Patent number: 7705274Abstract: A cooker has an external circulation path outside a heating chamber in which foods are to be placed. A blower sucks in gas inside the heating chamber, and forms, in the external circulation path, a gas flow that makes the sucked gas return to the heating chamber. Downstream of the blower, the external circulation path is provided with an exhaust port, in which a damper is provided. The damper closes the exhaust port during cooking, and opens the exhaust port when a door of the heating chamber is opened. After the damper is changed to a position of opening the exhaust port, the blower continues to operate until a predetermined condition is satisfied.Type: GrantFiled: August 5, 2004Date of Patent: April 27, 2010Assignee: Sharp Kabushiki KaishaInventors: Yuhji Andoh, Toshiyuki Irie, Shinya Ueda, Masami Umemoto, Tadanobu Kimura, Fuminori Kaneko, Yoshikazu Yamamoto, Masahiro Nishijima
