20080237947Actuator Arrangement for Active Vibration Isolation Using a Payload as an Inertial Reference Mass - System for and method of active vibration isolation to isolate a payload (10-02-2008
20090039575Vibration Control Mass Body - Provided is a vibration control mass body, as a mass body used for controlling with a high accuracy a vibration associated with high-speed movement of a movable body such as a stage, which is large-sized and to which a complicated shape can be imparted. The vibration control mass body (02-12-2009
20090108510Screw type inerter mechanism - A screw type inerter mechanism includes a screw with a limit portion and a thread portion with threads; a screw cap engaged with the thread portion of the screw; an inertia body fixed to the limit portion of the screw; and a connection body engaged with the limit portion of the screw wherein an axial of the screw serves as a rotation axial for the screw to rotate relatively to the connection body. Thus, when a non-zero external force is applied to the inerter mechanism to generate relative horizontal displacement between the screw cap and the connection body, the screw cap brings the screw to rotate, which further brings the inertia body to rotate, thereby achieving the inerter features.04-30-2009

267150000 CENTERING DEVICE 3
20130069290SPRING DEVICE FOR DOOR HANDLE - The spring device contains an upper plate, a lower plate, and a base sandwiched between the upper and lower plates. The base has a major opening and a side opening for accommodating a first elastic element and a second elastic element, respectively. The first elastic element has its two ends fixed to two positioning posts on the lower plate. A rotational seat also positioned in the major opening of the base has an arm fixed to a central part of the first elastic element. The upper and lower plates are then riveted together to house the other components inside to form the spring device. After the spring device is configured with a door handle, the door handle can be turned clockwise or counterclockwise to open/close a door and the door handle is then automatically restored to its original position after turning.03-21-2013
20130214465SPRING BOX FOR DOOR HANDLE - The spring box contains a base piece, a front plate, a back plate, a rotational piece, and a torsion spring. The base piece and the front and back plates have aligned through holes. A radial gap is configured on the rim of the base piece. The rotational piece has a curved sliding element along a section of the circumference. The sliding element has a groove, a weight block configured at one end of the sliding element, and a notch at the other end. The rotation piece is placed in the through hole of the base piece. The two ends of the torsion spring are embedded in the gap and the notch. The rotational and base pieces are sandwiched between the front and back plates. Then, by the weight of the weight block and the resilience of the torsion spring, a door handle is restored to its default position after being turned.08-22-2013
20140070470PASSIVE GUIDE SYSTEMS FOR LAMINATED SPRING ASSEMBLIES - In one embodiment of the invention, a patient side-system is provided that includes a column with a rail and a counterbalance subsystem. The patient side-system may further include a braking subsystem. The counterbalance subsystem includes a spring assembly coupled at one end to the column with a spring member, and a housing movably coupled to the rail. The housing includes a drum to receive the spring member and a plurality of roller elements to guide a movement of the spring member winding or unwinding on the drum. If present, the braking subsystem includes a first pulley rotatably coupled to the column, a second pulley with a locking mechanism spaced apart from the first pulley and rotatably coupled to the column, and at least one brake cable wrapped around the first pulley and the second pulley with ends coupled to the housing. The locking mechanism can set a position of the housing along the column.03-13-2014
267100500 PACKING EXPANDER OR CONSTRICTOR 2
20100090379SPRING LATCHING CONNECTORS - A spring latching connector includes a housing having a bore therethrough, a piston slidably received in said bore, a circular groove formed in one of said bore and piston and a circular coil spring disposed in said groove for latching said piston and housing together. The groove is sized and shaped for controlling, in combination with a spring configuration, disconnect and connect forces of the spring latching connection.04-15-2010
20130168906Helical Compression Spring for an Oil Scraper Ring of a Piston in an Internal Combustion Engine and Method for Coating a Helical Compression Spring - A helical compression spring, preferably of steel, in particular CrSi steel or CrNi steel, comprises a coating which has at least one a-C:H: Me coating or a plurality of layers of CrN (07-04-2013
267134000 FRICTION SNUBBER 1
20130015612RIVETED DIAPHRAGM SPRING HYSTERESIS PACKAGE - A hysteresis assembly, including: first, second, and third plates; at least one fastener connecting the first and third plates; and, at least one resilient element. The resilient element is: disposed between the first and second plates; disposed about the fastener; and arranged to urge the second plate into frictional contact with the third plate. A damper assembly, including: first and second cover plates arranged to receive torque; a flange axially disposed between the cover plates; at least one first resilient element engaged with the cover plates and the flange and arranged to transmit the torque to the flange; at least one fastener connecting the cover plates and passing through the flange; and at least one second resilient element. The resilient element is: disposed between the first cover plate and the flange; disposed about the fastener; and arranged to urge the flange into frictional contact with the second cover plate.01-17-2013
