  • Patent number: 9987019
    Abstract: An endoscopic treatment tool includes a sheath having a lumen, an elongated shaft inserted into the lumen and having an insertion passage, a stylet disposed in the insertion passage, an implant connected to the stylet, and a manipulation part main body provided on the sheath, a slider advanceable and retractable in an axial direction relative to the manipulation part main body, and a cam tube retracting while rotating in accordance with manipulation of the slider and having a spiral guide passage. A proximal end portion of the stylet has a projection engaged with the guide passage such that a force retracting the stylet is applied to the stylet by the cam tube retracting while rotating. The projection is slidable on the guide passage such that the stylet is advanceable relative to the elongated shaft against the force.

  • Patent number: 9776636
    Abstract: A calculation method and apparatus for calculating a starting point for acceleration/deceleration operation of a vehicle with high accuracy using more input values while at the same time keeping calculation cost and time to a minimum is disclosed herein. An ECU making up a system calculates a start point for acceleration/deceleration operation of a vehicle on the basis of traveling condition information that changes as the vehicle travels and vehicle information that changes only slightly as a result of the travel of the vehicle. As a result, if the driver maintains a throttle operator at a given opening angle or more at a point before the start point, an actuator applies a force in the direction of closing a throttle valve to the throttle operator, thereby notifying the driver that the vehicle is close to the start point.
