A handle is mounted on a first end portion of the axle mechanism and a rotatable plate structure is mounted on a second end portion of the axle mechanism. A column connecting simulator is attached to the plate structure and configured to support a beam-end component.

A cutting device capable of efficiently cutting an object with a simple configuration includes a grasp unit including a first grasper and a second grasper movable in an opening and closing directions to grasp the object, a cutting unit disposed side by side with the first and second graspers and moved in a cutting direction along the opening and closing directions to cut the object, and a position setter setting a cutting start position and a cutting end position based on respective positions of the first and second graspers that are grasping the object, respectively.

A fixing device includes a supporting platform configured to support a first workpiece, a receiving member, a plurality of pressing members, and at least one rotating member. The receiving member is positioned on the supporting platform and includes a rotating shaft. An axis of the rotating shaft is parallel to a supporting surface of the supporting platform. Each pressing member includes a first end and a second end. The first end is rotatably connected to the rotating shaft, and the second end can press a second workpiece to the first workpiece. The rotating member is positioned above the receiving member and detachably connected to each pressing member. The at least one rotating member can drive the pressing members to rotate to press or release the second workpiece. The present disclosure reduces the space occupied by the pressing members. The pressing of individual points can be realized.

A spacer assembly and method for using same to fix a first component to a second component are provided. The method includes positioning the first and second spacer segments between the first and second components, the first and second spacer segments each including an inner face, an opposite outer face, and an exterior surface extending along a longitudinal axis between the inner face and the outer face. The exterior surfaces of the first and second spacer segments are coaxially aligned and secured by a securing device such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis and the outer faces of the first and second spacer segments are parallel to one another. The securing device and the first and second spacer segments are removed after the first component is mechanically coupled to the second component.

A welding machine for welding free ends of bar conductors of a stator of an electrical machine, in particular an electric motor, includes a support structure for directly or indirectly fastening the stator. The support structure has a welding mask that can be opened and closed. The welding device is in particular a laser welding device. The welding device is arranged above the support structure. The support structure can be moved between a closed position and a loading position. A first side of the welding mask faces the welding device in the welding position and faces downward in the loading position. The welding machine allows free ends of bar conductors of a stator of an electrical machine to be welded while at the same time the stator is protected against contamination.

A device for the laser treatment of trousers, including a laser beam generating equipment suitable for emitting the laser beam in any direction within an emission pyramid with an emission axis and two opening angles, and a work station with two mannequins, where each mannequin includes two legs. Each leg defines a longitudinal axis, and the two longitudinal axes of each mannequin define a mannequin plane. Each of the mannequins is oriented towards the equipment so that the emission axis strikes the mannequin plane at an angle of less than 90° and each mannequin has at least one of its legs within the pyramid.

An engraving fixture for use with an engraver including a laser moveable along a linear X-axis path wherein the fixture comprises a base structure having two mutually extendable parts to assume different axial lengths thereby to accommodate objects of different lengths. The base can accommodate at an axial mid-point an auxiliary support for especially heavy objects. The base structure includes a support structure carrying the drive wheels and a stepper motor at one end, and a slidable passive support that can be placed at any location on the base member.

A method of using an oven includes supporting a substrate on a rotatable spindle in a processing chamber of the oven and rotating the substrate. The method may also include raising the spindle with the substrate to a heating zone and activating a lamp assembly to heat a top surface of the substrate. The substrate may then be lowered to a dosing zone and a chemical vapor directed into the processing chamber above the substrate. The substrate may then be further heated using the lamp assembly and cooled.

A workpiece rotating apparatus including a first rotary positioner and a second rotary positioner which are arranged to face each other in a direction along a substantially horizontal rotation axis, which hold, respectively, one end portion and the other end portion of a long workpiece, and which can rotate the workpiece around the rotation axis, a linear motor which linearly moves the second rotary positioner in a direction along the rotation axis, and a motor controller which controls the linear motor to adjust a position of the second rotary positioner in a direction along the rotation axis, and the motor controller controls the linear motor so that magnitude of force acting on the linear motor from the other end portion of the workpiece via the second rotary positioner becomes equal to or smaller than a predetermined threshold.

A solder reflow oven includes a processing chamber that defines an enclosure. The enclosure includes a spindle configured to support a substrate and rotate the substrate about a central axis of the processing chamber. The spindle is also configured to move vertically along the central axis and position the substrate at different locations within the enclosure. The oven further includes a chemical delivery tube configured to direct a chemical vapor into the enclosure, a lamp assembly configured to heat a top surface of the substrate, and a lift assembly configured to move the spindle along the central axis.
