Abstract: In a safety gear for an elevator, a pressing spring device applies a resistance force against movement of a normal-wedge guide member in a direction of moving away from a guide rail. A normal-wedge member has a reverse-wedge guide surface becoming more distant from the guide rail as extending upward. A reverse-wedge member is movable with respect to the normal-wedge member along the reverse-wedge guide surface. A vertical-direction spring device applies a resistance force against upward movement of the reverse-wedge member with respect to the normal-wedge member. A spring constant of the vertical-direction spring device is lower than a spring constant of the pressing spring device. The vertical-direction spring device has a region in which a rate of change in force generated along with increase in upward displacement amount of the reverse-wedge member with respect to the normal-wedge member decreases as compared to that in initial displacement.

Abstract: An elevator emergency safety device includes: a damper that includes a first sliding surface, and that is pressed against a guide rail to generate a braking force; a movable member that includes a second sliding surface that contacts the first sliding surface; and an elastic body that applies to the first sliding surface a pressing force that presses the damper against the guide rail, wherein: the damper is configured so as to be movable in a vertical direction relative to the movable member by the first and second sliding surfaces sliding; and the elastic body is configured such that the pressing force F1 increases, reaches a maximum value, and then decreases, as a position of a contacting portion between the first and second sliding surfaces moves upward.

Abstract: In an elevator apparatus, an abnormal acceleration detecting mechanism detects abnormal acceleration of an ascending/descending body due to breakage of a suspending body, and activates a safety device. The abnormal acceleration detecting mechanism includes: an inertia sheave that is rotatable around a sheave shaft independently from an interlocking sheave; a pawl that is connected to the interlocking sheave and the inertia sheave, and that is displaceable between a normal position, and an activating position that displaces a movable shoe to a gripping position; and an elastic body that holds the pawl in the normal position by applying an initial pressure, and that also rotates the inertia sheave together with the interlocking sheave.

Abstract: Provided is an elevator device including a main rope configured to support a car and a counterweight, a hoisting machine configured to be driven with the main rope wound therearound, a hoisting-machine controller configured to control the hoisting machine, a car brake controller configured to control a car brake device configured to apply a load to car rails to control raising and lowering of the car, and a vibration detection device configured to detect vibration of the car. When the vibration of the car is detected based on an output signal from the vibration detection device under a running state in which the hoisting-machine controller controls drive of the hoisting machine, the car brake controller controls the car brake device to generate a braking force until the vibration becomes smaller than a set value.

The solid ingredient is able to pass through a 3-mesh sieve but not through an 8-mesh sieve. The liquid condiment includes the solid ingredient in an amount of 10 to 60% by mass on a wet basis.

Abstract: A control cable guide device for an elevator, which is to be mounted to a control cable suspended between a middle portion of a hoistway and a lower portion of a car, the control cable having a curved portion formed at a lower end position of the control cable, the control cable guide device including an arm to be suspended on the control cable at a position below the car in a pivotable manner. The arm is configured to be pushed upward by the curved portion when the car is caused to travel to a lowermost position within a normal traveling range, to thereby shift to a cable receiving position for receiving the control cable while being partially projected from the car in a horizontal direction.

Abstract: An emergency stop device for an elevator car, including: a link configured to be rotated about a rotary shaft installed on a car by movement of a speed governor rope; a rail stopper provided to one end of the link; a roller guide mounted to the car; and an elastic member provided between another end of the link and the car. The elastic member causes a spring reaction force to be reduced to bring the rail stopper into abutment against the roller guide even when the rail stopper is displaced by the link, when the displacement exceeds a preset threshold value due to further displacement by the link along with the movement of the speed governor rope at a time of occurrence of rope breakage.

Abstract: In an elevator apparatus, a safety device that makes a car perform emergency stopping is mounted to the car. A rope is installed in a loop inside a hoistway. The rope is connected to the car. A tensioning sheave around which the rope is wound is disposed in a lower portion of the hoistway. A tensioning sheave displacement detecting portion detects downward displacement of the tensioning sheave that accompanies dropping of the car due to breakage of the suspending body and activates the safety device.

Abstract: In an elevator apparatus, a safety device is activated using a force that is generated by a mass body that includes sheaves and a rope, if acceleration of a car reaches an abnormal acceleration set value. A tensioning sheave that can be moved vertically in order to apply tension to the rope is included among the sheaves. A vertical vibration suppressing apparatus that is connected to the tensioning sheave allows vertical displacement of the tensioning sheave during normal operation while also suppressing vertical vibration of the tensioning sheave if the acceleration of the car reaches the abnormal acceleration set value.

Abstract: A method for controlling an operation of an elevator system is discloses. The elevator system includes an elevator car moving within an elevator shaft and at least one elevator cable connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The method determines a counter force on the elevator cable required to change a nominal shape of the elevator cable to an inverse shape of a current shape of the elevator cable caused by disturbance on the elevator system and applies the counter force to the elevator cable.

Abstract: Disclosed herein is a signal potential converter which may perform high-speed operation and which may still maintain intended signal amplitude and operate normally even while operating at a low rate or receiving a burst signal. In this signal potential converter, a capacitor receives an input signal CIN at one terminal thereof and has the other terminal thereof connected to a terminal node. A clamp circuit defines a potential at the terminal node, i.e., a signal IN, within the range of a first potential to a second potential. If a potential at the terminal node is higher than a third potential, a voltage holder circuit operates to raise the potential at the terminal node. If the potential at the terminal node is lower than the third potential, the voltage holder circuit operates to lower the potential at the terminal node.
