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.

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.

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.

A conveyor apparatus is provided that is free of a pulsing motion in the circulating chains so as to provide a comfortable ride quality on its steps. The conveyor apparatus includes a step guide rail, a plurality of steps, a step chain, and a chain driving mechanism for driving the step chain. The chain driving mechanism includes a rotating and driving unit, a driving sprocket which is rotated by a driving force given by the rotating and driving unit, and a circulating chain for giving a thrust to the step chain. The circulating chain has chain links and hinges that are to be connected to the adjacent chain links. The chain link includes a placing surface on which the step roller is placed, and pressing surfaces that are in contact with step rollers.

A conveyor apparatus comprises step chains which couple a plurality of steps such that the steps, and driving units which drive the chains. Each of the driving units comprises a power unit comprising a motor, and a driving machine including pulleys and belts that reduce a rotation speed of the motor so as to meet a required reduction gear ratio and transfer the rotation speed to the chains, and a pair of right and left driving mechanisms that convert a rotary movement transferred from the machine of the power unit via an eccentric shaft into a movement of rocking units, and apply a propelling force to the chains via pin rollers provided at any one of sides of the rocking units and the chains and gears provided at the other side of the rocking units and the chains to engage with the rollers.

An elevator door apparatus includes an engaging device which engages car doors with hall doors. The engaging device uses a spring unit to urge a movable vane provided in each of the car doors. While the doors are moving, engaging rollers supported by the hall doors are sandwiched between the movable vane and a fixed vane. Thus, the driving forces of the car doors are transmitted to the hall doors. When the hall doors reach a door stop position, the movable vane is moved away from the fixed vane. Thus, the car doors are disengaged from the hall doors. At this time, a direction in which the elastic force of the spring mechanism acts is switched. Consequently, the car doors and the hall doors are stably held so that the car doors remain disengaged from the hall doors.
