  • Patent number: 8482661
    Abstract: A power transmission mechanism includes a rotational drive member which rotates to drive a driven member, a drive switcher for switching between a transmission-ON state in which a driving force of a drive source is transmitted to the rotational drive member to rotate the rotational drive member and a transmission-OFF state in which the transmission of the driving force to the rotational drive member is canceled, and a rotation restrictor which allows the rotational drive member to rotate when the drive switcher is in the transmission-ON state and is engaged with the rotational drive member to restrict rotation of the rotational drive member when the drive switcher is in the transmission-OFF state.

  • Patent number: 8066722
    Abstract: A clip applier includes a body 21, an insertion tube 22 extending from the body 21 and inserted in a channel of an endoscope and a clamp mechanism 24 disposed at a distal end of the insertion tube 22. The clamp mechanism 24 has a support member 28 fixed at the distal end of the insertion tube 22 and a pair of clamp members 30 rotatably supported by the support member 28. The clamp members 30 are connected to a distal end of a wire 25 via a pair of links 35. The clamp members 30 respectively include gripping portions 32 protruding form the support member 28. A clip 50 is received in receiving grooves 32a of the gripping portions 32. When the wire 25 is pulled by operating an operation member disposed on the body 21, the clamp members 30 are rotated against an elastic force of a hinge portion 51 of the clip 50, thereby causing a pair of clip portions 53 of the clip 50 to be opened.

  • Patent number: 7997807
    Abstract: A power transmission mechanism includes a cam-incorporated gear including a constant-radius cam-portion and a small-radius relief cam-portion connected via a non-constant-radius cam-portion; and first and second swingable members each including a follower which comes in contact with the constant-radius cam-portion and is positioned in an immediate vicinity of the relief cam-portion at respective first and second swing limits. The cam-incorporated gear includes two neutral positions in which one and the other of the swingable members is held at cam-axis separated and vicinity positions, respectively, wherein upon rotating the swingable members from one to the other of the neutral positions, the commencement and termination of rotation of the swingable member that moves from the cam-axis separated to vicinity positions respectively occurs at earlier and later timings. The non-constant-radius cam-portion makes a load torque greater than a surplus torque which act on the cam-incorporated gear when it rotates.

  • Patent number: 6175111
    Abstract: A method for diagnosis of components inside a turbine generator includes collecting and measuring organic substances present in a gas inside the turbine generator to obtain data (first data). Before the collecting, organic substances generated from each component inside the turbine generator due to heat, discharge, corrosion, or friction, are measured to compile data (second data). The first data is compared to the second data to determine whether the first data includes the same data as in the second data to detect deterioration of the components inside the turbine generator.
