    摘要: Λn electrical power tool (1) includes a housing (10,20,30) , an electrical motor (21) , a motion conversion mechanism (36) , a counterweight holding member (73) , a counterweight (74) , and support members (71,72) . The electrical motor (21) is accommodated in the housing (10,20,30) . The motion conversion mechanism (36) is configured to convert a rotary motion of the electrical motor (21) into a reciprocation motion. The counterweight holding member (73) extends in a direction perpendicular to directions of the reciprocation motion and is capable of being elastically deformed in the directions of the reciprocation motion. The counterweight (74) is supported by the counterweight holding member (73) and is capable of reciprocating in the directions of reciprocation motion together with the counterweight holding member (73) . The support members (71,72) are positioned away from the counterweight (74) by a predetermined distance for supporting the counterweight holding member (73) to the housing (10,20,30) . The counterweight (74) is interposed between or among the support members (71,72) .

    摘要: An inertial mass (50) for a vibration isolator (20) having an attachment fitting (22) adapted for rotation about an axis (16) and a spring means (40) adapted for rotation with the attachment fitting (22). The inertial mass (50) is characterized by a pair of segments (52) each having a generally Z-shaped cross-sectional configuration. More specifically, each segment (52) defines a central web (54), a first leg (56) projecting radially inboard of the central web (54) and a second leg (58) projected radially outboard of the central web (54). The first and second legs (56, 58) are integral with the central web (54) and the second legs (58) are adjoined along a mating interface (I) to define the assembled inertial mass (50). As assembled, the inertial mass (50) is adapted for being mounted in combination with the spring means (40) of the vibration isolator (20). Preferably, the second legs (58), in combination, define a mating flange (62) which is adapted for mounting at least one tuning weight (64), and, the first legs (56) define circular abutment surface (68) adapted for coacting with an opposing abutment surface (70) of the attachment fitting (22).

    摘要: An apparatus for reducing rotation of an article such as a bird for holding a superconducting quantum interference device for use in airborne transient electromagnetic mineral prospecting. The apparatus includes a support sphere (20) having an inner shell (23) and an outer shell (21). Liquid is contained between the inner and outer shells (21 and 23) and the sphere (20) has openings (22) through which support strings project for locking to an internal point within the sphere. The strings (24) have one end connected to an internal point within the support sphere (20) and another end connected to a spring (14). The spring (14) includes a damper (18) for damping movement of the spring (14). Baffles (50) are arranged in the cavity between the inner and outer shells in which the liquid is contained for damping movement of the liquid.

    摘要: A damping device (15) includes a base member (20) fixed to a vibration suppression target, a first coil spring (21), a second coil spring (22), and a weight member (23). The first coil spring (21) includes a first fixed-side end turn portion (40) supported on a first support portion (31) of the base member (20), a first effective portion (41), and a first movable-side end turn portion (42). The second coil spring (22) includes a second fixed-side end turn portion (50) supported on a second support portion (32) of the base member (20), a second effective portion (51), and a second movable-side end turn portion (52). Each of the first coil spring (21) and the second coil spring (22) is deflected in a longitudinal direction along the axis (Z0), and a transverse direction perpendicular to the axis (Z0). The weight member (23) is arranged between the first coil spring (21) and the second coil spring (22), and moves in the longitudinal direction and the transverse direction.
