In an unbalance torque compensating device, the supporting member has an engagement surface that receives, through the engaging portion, a first rotary torque T1 applied to the rotating shaft. The urging member causes a second rotary torque T2 in a direction opposite to the first rotary torque T1 to be generated at the rotating shaft through the engaging portion.

A tilting table device includes a first rotary member which is rotated by a rotation amount equivalent to that of a tilt shaft when rotation of the tilt shaft is transmitted; a second rotary member which has an axis parallel to that of the first rotary member and is rotated by a rotation amount equivalent to or substantially equivalent to that of the first rotary member in a direction opposite to that of the first rotary member when the rotation of the first rotary member is transmitted; two retaining members respectively provided at the first and second rotary members, in which when the center of gravity of a table is located at an uppermost position or a lowermost position, the retaining members are located on or near a line connecting rotation centers of the first and second rotary members, the retaining members are located at equivalent or substantially equivalent distances respectively from the rotation centers, both the retaining members are provided inside or outside the two rotation centers; and an urging device which causes a constant urging force to be applied between the two retaining members so as to reduce a torque applied to the tilt shaft by movement of the center of gravity from the uppermost position or the lowermost position as a result of the rotation of the tilt shaft.

A coupling device for linear drives for linking a drive part performing a linear movement in an axial direction with a guide part guided for longitudinal movement on a longitudinal guide parallel to the direction of movement. A force input part connected with the drive part and a force output put part connected with the guide part are provided, the force input part and the force output part being coupled together kinetically by means of an intermediately placed link member. As a link member and a elongated or longitudinal spring member is provided which is able to be bent in at least one transverse direction in a resiliently elastic manner and is non-yielding in its longitudinal direction, said spring member being aligned at least substantially in the axial direction. It is secured at a first connection point to the force input part and at a second connection point spaced from the first connection is connected with the force output part, in each case non-movably in the axial direction.

An X-stage is moved in an X direction (horizontal direction), and a Y-stage is moved in a Y direction (vertical direction) by linear motors. The gravitational force of the Y-stage is canceled out by a constant tension spring. Tensile force irregularity in the constant tension spring is measured in advance and stored in a tensile force irregularity compensation table. The tensile force irregularity is canceled out when a controller controls an auxiliary motor.

Process for welding a weld-in part in a weld point comprising a metal plate and a metal covering lying thereon with two tools of which one is formed by a welding head and the other by a drill for preparing the weld point by a drilling process. The drill attached to a revolving device initially in one operating position, by means of a lifting motor which can be moved in a controlled manner between a return position and a machining end-position and vice versa, performs the process at least until the metal plate is drilled (machining end-position) in preparation of the weld point. By pivoting of the revolving device, a welding head arranged on the revolving device and equipped with the weld-in part is then brought into an operating position above the prepared weld point to perform welding, meanwhile the drill is coupled to the lifting motor when the welding head is coupled to the lifting motor when the drill is uncoupled to perform welding on completion of the drilling process. Drill and the welding head are each set aside in their return position on a rest shoulder after pivoting of the revolving device, the welding head being equipped with a weld-in part in the rest position and the revolving device pivoting the drill or the welding head into the respective operating position from the rest position.

In a machine tool having cooperating first and second slides slidably with respect to one another, an improved way damper has a damper plate carried by the first slide in slidable engagement with the second slide, and the plate is retained so as to permit slight movement of the plate in a normal direction to the movement of the first and second slides. A sealed damping chamber is formed between the damper plate and the first slide, having a viscous medium within the chamber which effects squeeze film damping as the damper plate and first slide undergo relative vibratory motion. An alternate embodiment employs a visco-elastic medium in the damping chamber to effect damping.

A table extension for a table saw comprises a generally rectangular member extending from one end of the table, and a clamp for securing the member to a rail at that end of the table such that the top surface of the member and that of the table are substantially coplanar. A leg structure is secured to the underside of the member, which leg structure projects downwardly terminating in rollers which are adapted to engage a bearing plate on the saw table support. A pair of brace rods extend upwardly from the leg structure for engagement with a bottom plate on the underside of the extension.
