Abstract: Provided is a passenger-conveyor step-chain monitoring system capable of monitoring elongation of a step chain without adding a special device. The passenger-conveyor step-chain monitoring system includes a monitoring unit configured to monitor elongation of a step chain attached to a step of a passenger conveyor based on a result of detecting the step by a sensor provided to detect an absence of the step. With this configuration, it is possible to monitor elongation of the step chain without adding a special device.

Abstract: Provided is an abnormality detection device, in which a sound signal acquisition unit connected to a passenger conveyor converts a sound wave around each of inspection guide shoes mounted to a step into a sound signal. A sound signal analysis unit analyses the sound signal and extracts a sound pressure or a main frequency. The controller has not only a function as a command unit configured to command an operation for causing the step to run but also a function as an abnormality determination unit configured to determine an abnormality in skirt guards based on the sound pressure or the main frequency. The sound signal analysis unit in the abnormality detection device analyzes the sound signal acquired by the sound signal acquisition unit under a state in which the step is caused to run, and extracts the sound pressure or the main frequency.

Abstract: A plurality of steps are linked by endless step chains. Each of the steps includes: a step main body; first shafts that are disposed on the step main body; first step rollers that are disposed on the first shafts, and that are guided by the first guide rails; second shafts that are parallel to the first shafts; and second step rollers that are disposed on the second shafts, and that are guided by the second guide rails. The first shafts move along first pathways, and the second shafts move along second pathways. The second pathways are positioned inside the first pathways when viewed parallel to respective shaft axes of the first shafts. The step chains link each of the steps by joining the second shafts of each of the steps, and are disposed within a range of the step main body in an axial direction of the first shafts.

Abstract: In the step for a passenger conveyor, a sleeve includes a sleeve main body, which has a tubular shape and is slidable with respect to a main shaft portion along an axis line of the step shaft, a claw to be hooked to a level-difference portion formed at a boundary between the main shaft portion and a projecting shaft portion, and a connecting portion configured to connect the sleeve main body and the claw. The connecting portion includes an arm portion which is elastically deformable in a direction in which the claw is unhooked from the level-difference portion. A mounting portion, having a recessed portion formed therein, is fixed to the step main body. The recessed portion is fitted over an outer peripheral surface of the sleeve main body. An open portion of the recessed portion is smaller than an outer diameter of the sleeve main body.

Abstract: The present invention provides a tablet for treating postherpetic neuralgia and a method of treating postherpetic neuralgia with the use of the tablet. The therapeutic tablet for postherpetic neuralgia according to the present invention is characterized in comprising buprenorphine hydrochloride, having a double layer structure consisting of a quick-release layer and a sustained-release layer, wherein the tablet is adhesive to the oral mucosa.
