摘要： PROBLEM TO BE SOLVED: To efficiently cool a secondary conductor by installing a means for cooling the secondary conductor in a counterweight in which the primary windings are provided, and cooling the secondary conductor from the counterweight. SOLUTION: When an order to operate an elevator is given, power is supplied to primary windings 3 from a control device 8 consisting of an inverter, and by electromagnetic interaction of the primary windings, current flows to a secondary conductor 7 to generate thrust to raise or lower a counterweight 2, and a car 1. At this time, the secondary conductor 7 produces heat, since higher current flows to it. The heat is cooled by blowing the cooling wind of a fan 6 against the secondary conductor 7 after the fan 6 is provided in the counterweight in which the primary windings 3 are installed. Since current of the secondary conductor 7 is generated as eddy current on the part facing the primary windings 3, the secondary conductor 7 can be cooled as the counterweight 2 is moved.

摘要： PURPOSE: To suppress the generation of oil beat in piping and reduce acceleration shock to a car at the time of a car ascent/descent start command in a fluid pressure elevator using a bidirectional flow fluid pressure pump and provided with a means for storing fluid pressure energy. CONSTITUTION: In a fluid pressure elevator using a bidirectional flow fluid pressure pump 1 and provided with a fluid pressure energy storage means 10, a throttle 9 is inserted in the pilot passage 27 of a flow control valve 4 in order to slowly open this main valve 4, and the inflow of a pressure fluid to the pilot chamber of the main valve 4 is suppressed to slow down the action speed. The sudden rise of pressure is thereby suppressed, so that the generation of oil beat and oil beat noise in piping is suppressed, and acceleration shock to a car is reduced so as to improve the riding comfort of the fluid pressure elevator and to enable power reduction.

摘要： PURPOSE: To prevent sinkage and flotation of a passenger cage caused by getting-in-and-off of passengers at the time when an elevator stops by engaging a pair of arms with holding means arranged on left and right guide rails by way of driving a driving means at the time when the elevator stops. CONSTITUTION: A passenger car 10 which stops at a story floor platform 30 rotates a starting motor in the counterclockwise direction by a control device 40 before a passenger cage door opens. Consequently, a pair of arms 14 moves in the direction of a guide rail 20 along a guide 17 supported and guided on a bottom part of the passenger car 10 and engaged with a bracket 21 along a guide 23 of the bracket 21. Thereafter, the passenger cap door opens and getting-in-and-off of passengers is started. As dead weight of the passenger car 10 and weight of the passengers are all supported by the guide 17 of the passenger car 10 and the guide 23 of the bracket 21, it is possible to prevent sinkage and flotation of the passenger car 10 at the time of getting-on-and-off of the passengers due to growth of bubbles in a high pressure fluid in a cylinder 1 and expansion and contraction of a rope 8 as the high pressure fluid is supplied from a fluid pressure pump 3 and discharged from the fluid pressure cylinder 1 to a fluid tank 6.

摘要： PROBLEM TO BE SOLVED: To provide an escalator on which a passenger can get without waiting with a general pedestrian even if the passenger sits on a wheelchair. SOLUTION: If the wheelchair 6 gets on a movement landing plate 5 and the passenger 7 operates a switch 8, an escalator controller 9 makes the movement landing plate 5 and a step 10 move synchronously when the step 10 comes to a synchronous position. The movement landing plate is kept at the horizontal state by a guide rail 11. The escalator controller releases the synchronization of the movement landing plate and the step by the signal of a movement landing plate detecting means 12 in a getting-off exit. The movement landing plate stops after the synchronization is released. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an elevator having secured safety and reliability by suppressing the decrease of the life and the strength of a rope when the diameter of a sheave is reduced. SOLUTION: The rope in a structure, in which each of plural wires constituting the wire rope is covered with a resin material and the whole wire rope is covered with the resin material is used to reduce the abrasion caused by the mutual slip of each wire when being wrapped around the sheave, and the abrasion caused by the contact with the sheave. As a result, the reduction of the rope life worried when the diameter of the sheave of the elevator is decreased, is suppressed or improved. Thereby, the miniaturization and lightening of equipment such as a motor and a winding machine, the saving of the space for installing the elevator, and the improvement of the safety and reliability of the system caused by the increase of the rope life are intended.

摘要： PROBLEM TO BE SOLVED: To lighten a bottom of a hoistway and a steel skeleton in the hoistway. SOLUTION: A car 12 and a balancing weight 13 are vertically movably mounted in the hoistway 11. A frame body 16 formed by a framed construction is mounted on the bottom of the hoistway 11, and a car bumper 18 or the like is mounted in the frame body 16. Upper parts of a car rail 14 and a balancing weight rail 15 are fixed to a cross beam 20, lower parts thereof are fixed to the flame body 16, and the load of the car 12 and the balancing weight 13 is supported by the frame body 16 through both rails 14, 15. A base isolation mechanism 25 is mounted between a building 10 and a foundation construction 24. Further a shielding wall 26 is mounted around the frame body 16 for preventing the outside air from flowing in the hoistway 11 through a clearance between the building 10 and the foundation construction 24. This shielding wall 26 is made of a soft heat-resisting member 26B.

摘要： PROBLEM TO BE SOLVED: To dispense with link mechanisms for interconnecting consecutive pallets from variable-speed passenger conveyors of a type where pallets are adjustable in their interval. SOLUTION: This variable-speed passenger conveyor comprises low-speed driving chains 4 engaged with pallets and driven at a constant low speed, high- speed driving chains 8 driven at a constant high speed, acceleration driving chains 6 for driving the pallets at an accelerated speed, and deceleration driving chains 10 for driving the pallets at a decelerated speed. The plural acceleration and deceleration driving chains 6 and 10 are driven by respective accelerating and decelerating motor means each actuated individually by a single motor. The accelerating and/or decelerating driving chains 6 and/or 10 are a plurality of driving chains adapted to operate at an independent speed and/or acceleration and mesh with at most one set of pallets at one time to drive them only. The variable-speed passenger conveyor is thus simplified in its acceleration/ deceleration sections.

摘要： PROBLEM TO BE SOLVED: To reduce the installation space of a moving footway, by providing a means for making the height directional dimension of a handrail when a pallet after carrying passengers reverses at an alighting place to return to a landing direction, smaller than the height directional dimension of the handrail at the time of carrying passengers. SOLUTION: A moving footway reverses at the lower part of an alighting place 9 as shown in respective pallet positions 1a-1c, after a pallet 1 moves from a right upper part to a left lower part in a figure, to carry passengers, and then moves from the left lower part to the right upper part to return to the landing. At that time, the handrail 7 is folded as shown in respective handrail positions 7a-7c, to shorten a vertical directional height dimension at the time of return. A portion where the handrail 7 appears at the landing is arranged in this side in a progress direction, than a portion where the pallet 1 appears at the landing. Moreover a drawing part, for drawing the handrail 7 at the alighting place, is arranged in a deep side in the progress direction than a drawing part for drawing the pallet 1 at the alighting place.
