  • Publication number: 20180279854
    Abstract: 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.

  • Patent number: 9551661
    Abstract: An assay chip includes fluidic-channel member composed of a light-transmissive lower member and an upper member, forming a fluidic-channel therebetween, and a cover member fitted with the fluidic-channel member from the upper-member-side thereof. An inlet for injecting a sample solution into the fluidic-channel and a suction opening for sucking, from the downstream side, the injected sample solution, both communicating with the fluidic-channel, are formed on the upper surface of the upper member. A pot for carrying out predetermined pre-processing on the sample solution, a pot for first-reaction processing to bind a photoresponsive labeling substance to an analyte in the sample solution, an inlet insertion-hole for inserting the inlet, and a suction-opening insertion-hole for inserting the suction opening are linearly arranged on the upper surface of the cover member.

  • Patent number: 8802426
    Abstract: A device for assay can evenly develop solution, and performs highly accurate and sensitive measurement. A first device part (10) maintains a second insoluble carrier (12) and a third insoluble carrier (13) in such a manner that they overlap with each other at a detection portion (14) of a first insoluble carrier (11). These three carriers (11), (12) and (13) are housed not in contact with each other. A pressing unit (18) having a pressing surface (18a) that is parallel to the detection portion (14) is provided on an inner surface of the second device part (20) facing the detection portion (14). The pressing surface (18a) is displaced by being pressed toward the detection portion (14), and presses, from the upper side of the first insoluble carrier (11), the second insoluble carrier (12) and the third insoluble carrier (13) onto the first insoluble carrier (11). The first device part (10) and the second device part (20) are joined together.

  • Patent number: 8470262
    Abstract: 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.
