Publication number: 20180279854Abstract: An object of the invention is to provide an operation mechanism, an endoscope, and a manufacturing method that can reliably fix an operation wire to a member to be operated. According to an operation mechanism of an aspect of the invention, since a sleeve member is caulked in a caulked shape where a twisted shape of a plurality of strands of an operation wire is maintained, the sleeve member is caulked while the strands are maintained in an original line contact state. Accordingly, since damages to the strands caused by a point contact state of the strands do not occur, the tensile strength and bending durability of the operation wire are improved and the operation wire can be reliably fixed to a member to be operated. Further, since the sleeve member, which is externally fitted to the operation wire, is fixed to the member to be operated, other fixing members are not required. Accordingly, a fixing portion can be reduced in size.Type: ApplicationFiled: March 14, 2018Publication date: October 4, 2018Applicant: FUJIFILM CorporationInventors: Kota KATO, Nobuhiko FUJIWARA, Hideyuki KARAKI

Patent number: 8470262Abstract: It is a microfluidic device including a flowchannel in which liquid flows. The flowchannel includes a main channel and a pair of branch channels provided across the main channel from each other to be each connected to the main channel. The main channel includes a first zone, a second zone, and a coupling zone that connects the first zone and the second zone. The second zone is smaller than the first zone in a distance between a bottom surface and a ceiling surface. The coupling zone is configured such that the distance between the bottom surface and the ceiling surface thereof gradually decreases towards the second zone from the first zone. A connection zone provided in the main channel and connected to each of the pair of branch channels overlaps with the coupling zone.Type: GrantFiled: February 9, 2011Date of Patent: June 25, 2013Assignee: FUJIFILM CorporationInventors: Hideyuki Karaki, Yoshihiro Sawayashiki
