    摘要： Provided is a moving unit (1) that enables a movable body (41) to be smoothly moved along guide tracks (2) for guiding the movable body (41) across joints between a plurality of track rails (21) arranged in series so as to serve as the guide tracks. The moving unit (1) includes: the pair of guide tracks (2) laid in parallel to each other; a plurality of moving blocks (3) being two or more moving blocks (3) assembled to each of the guide tracks and being freely movable along the guide tracks; and the movable body (41) fixed to the moving blocks. The track rails (21) arranged in series serve as the guide tracks, and each have a guide surface (25) formed along a longitudinal direction of each of the track rails. The moving blocks (3) each include contact elements (31) configured to travel on the guide surface while passing across joint clearances (L) each being formed between the track rails arranged in series. When one of the moving blocks (3) is positioned at any one of the plurality of joint clearances (L) formed on the pair of guide tracks (2), another of the moving blocks is not positioned at another of the joint clearances.

    摘要： Provided is a damping device that is smaller in size and capable of increasing a damping force with respect to vibrational energy that is propagated between two structural bodies. The damping device includes: a fixed cylinder (2) that is configured to be fixed to a first structural body and formed into a cylindrical shape so as to comprise a hollow portion; a shaft member (3) that is configured to be fixed to a second structural body, the shaft member (3) being housed in the hollow portion of the fixed cylinder (2) and having an outer peripheral surface provided with a helical thread groove; a nut member (4) that is threadedly engaged with the shaft member, and converts an axial motion of the shaft member into a rotational motion; a rotor member (6) that is formed into a cylindrical shape so as to cover the fixed cylinder (2) and to form a cylindrical accommodation chamber (8) between the rotor member (6) and an outer peripheral surface of the fixed cylinder, and is rotated by the nut member (4); and viscous fluid (7) that is sealed in the cylindrical accommodation chamber (8).

    摘要： A linear motor device includes a linear motor and a controller that applies pressure to a pressurizing target by moving a needle provided with the linear motor. The controller includes: a speed-change position-setting unit that calculates a deceleration start position, which is a position where a movement speed of the needle starts to be reduced from a first speed to a second speed when the pressurizing target start to be pressurized, based on a distance required to reduce the movement speed of the needle from the first speed to the second speed which is lower than the first speed and at which pressure applied to the pressurizing target when the needle comes into contact with the pressurizing target is equal to or lower than a predetermined pressure; and a position determination unit that drives the needle of the linear motor at the first speed when the needle is moved from a predetermined toward the pressurizing target, and moves the needle at the second speed when the needle reaches the deceleration start position.

    摘要： Provided is a screw motion mechanism capable of facilitating connection of an axial end of a threaded shaft with respect to a structural body while preventing a rotation of the threaded shaft, and capable of preventing application of an excessive torque to a nut member and the threaded shaft and preventing damage on those members. The screw motion mechanism includes: a threaded shaft (30) having an outer peripheral surface provided with a helical thread groove, the threaded shaft (30) having at least one axial end coupled to a first structural body; a nut member (40) held in a rotatable manner with respect to a second structural body which is movable in an axial direction of the threaded shaft with respect to the first structural body, the nut member (40) being threadedly engaged with the threaded shaft; and a spherical joint (32) for coupling the at least one axial end of the threaded shaft (30) to the first structural body, the spherical joint (32) including: a spherical portion (33, 61); and a sphere receiving portion (36, 60) for housing the spherical portion. When assuming an axial force applied to the threaded shaft (30) as a variable, a line of a rotational torque intersects with a line of a sliding torque in a graph, and the sliding torque exceeds the rotational torque under an initial state in which the axial force is not applied to the threaded shaft (30).
