A footstep guide rail () (rail body) is arranged so that a level H of a horizontal surface is set at the position obtained by adding a designated offset &#x3b4; to a tangential line L of a drive sprocket () and the footstep guide rail () is provided, at its one end on an introductory side of the drive sprocket (), with a curved part (). At a reference position closest to the drive sprocket (), the horizontal surface of the footstep guide rail () is changed to the curved part (). Consequently, it is possible to absorb velocity unevenness of one footstep roller approaching the drive sprocket ().

Conveyer apparatus

A mountainous or valley-shaped curved partis provided in a part of a footstep guide railfor guiding a movement of footstep rollerslinked by a footstep chain, the part being positioned in the vicinity of a drive sprocket. Consequently, owing to meshing of the footstep rollerswith the drive sprocket, an unevenness in velocity of the footstep rollersis absorbed by the curved part, so that a moving velocity of the footstep rollersmoving on the downstream of the curved partis maintained constantly, suppressing vibrating of the footsteps

An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave and a driving mechanism is positioned between an inner wall of the elevator path and a space occupied by an elevator car rising and falling in the elevator path . One end of a suspension rope is fixed to the elevator car in a position below a ceiling of the elevator car . With the arrangement, the car can move close to the ceiling of the elevator car effectively. Further, it is possible to reduce respective heights of the elevator path and a building equipped with the elevator apparatus.

Traction type elevator apparatus

In an elevator, a driving unit is installed at the top of an elevator shaft above a counterweight. Traction sheaves engage with ropes and are rotated by the driving device. These traction sheaves are positioned close to wall surfaces of the elevator shaft, that are adjacent to its wall surface facing the counterweight. The traction sheaves are also positioned outside the horizontally projected plane of a car.

The inspection apparatus for inspecting performance of a structure such as stator windings of an electric rotating machine of the invention comprises a probe including a measuring element, an arm unit and a cylinder face circumferential moving apparatus. The arm unit has an arm link section supporting the probe (mainly comprising a leading end link assembly and an arm posture keeping mechanism), an arm housing section (mainly comprising a guide rail) regarding driving of this arm link section, and an arm driving mechanism. The arm driving mechanism causes the leading end link assembly to project from the guide rail at an angle toward a measuring position side of the stator windings relative to the axial direction of the rotor unit, while causing the arm link section to travel along the guide rail. The arm posture keeping mechanism is provided with a link wire and a spring, and maintains a straight arm posture of the leading end link assembly after projection from the guide rail.

This invention provides a convey apparatus capable of conveying a convey target without locally applying an excessive force to it. The convey apparatus includes a convey portion and a medium pressure switching unit. The convey portion has a plurality of medium passages for passing a medium therethrough, and at least part of the surface of the convey portion is made of an elastic material. The diameters of the medium passages can be freely increased/decreased. The medium pressure switching unit controls the pressures of a medium supplied to the respective medium passages of the convey portion to increase or decrease the diameters of the medium passages, thereby generating a carrier wave on the surface of the convey portion. Therefore, according to this convey apparatus, the pressures of the medium supplied to the respective medium passages of the convey portion are controlled by the medium pressure control unit in order to increase or decrease the diameters of the medium passages, thereby generating a carrier wave on the surface of the convey portion made of the elastic material. In this way, convey targets ranging from a flat convey target to a three-dimensional convey target can be conveyed without locally applying an excessive fore to them.

Convey apparatus, and movable driving mechanism for movable work

A method and an apparatus for carrying a workpiece for improving efficiency in a workpiece carrying operation. In the apparatus, a moving member having a workpiece holding member is driven with a linear motion in a horizontal plane along a carrier passage, and the workpiece holding member is driven with a revolutional motion in a vertical plane around a revolution axis displaced from a center of the workpiece holding member, while the workpiece holding member maintains an orientation in which a holder holding the workpiece points downwards. The holder of the workplece holding member is controlled to sequentially carry out holding of the workpiece and releasing of the workpiece at lowest positions of the workpiece holding member in the revolutional motion, so as to realize a continuous workpiece carrying operation.

A work mounting apparatus according to the present invention comprises a rotating drum divided into upper and lower drums, a head unit arranged on the outer periphery of the rotating drum or the lower drum, a circular work head attached to the head unit, and a suction nozzle protruding from the outer peripheral surface of the work head toward a workbench. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture or orientation kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench. The work mounting apparatus further includes a balance weight for the work head, and a friction brake for applying a frictional force to the turning shaft of the work head, to thereby stabilize the turning motion of the work head.

A remote control apparatus for maintaining a tokamak type nuclear fusion reactor comprises a rail having a plurality of arcuated links to be extended in a circumferential direction and a plurality of joints for pivotally connecting the adjacent arcuated links, a vehicle running on the rail extended so as to form a continuous arc with its center substantially coinciding with the center of the torus space, and at least one handling device mounted on the vehicle, for handling the in-vessel components. The remote control apparatus is further provided with a rail housing device for receiving the arcuated links in a folded state when they are not in use, a rail mounting device for sending out said arcuated links in succession into the torus space, extending them so that they form a continuous arc and supporting the arcuated link on the proximal end of the rail, and a rail supporting device for supporting the central portion of the rail extended in the torus space.
