According to one embodiment, a diagnostic system includes a conveyor device first and second sensors and a diagnostic device. The conveyor device includes an endless chain having a plurality of rollers coupled at regular pitches and each fit into a bush, to circularly move between a first sprocket and a second sprocket. The first and second sensors diagonally are disposed apart from each other on a moving path of the chain, irrespective of an operating direction of the conveyor device, to detect a passage of each of the rollers of the chain. The diagnostic device measures an amount of elongation of the chain based on a first detection signal output from the first sensor and a second detection signal output from the second sensor according to movement of the chain during operation of the conveyor device.

Diagnostic system

Disclosed is a remote monitoring diagnostic system in which a center and monitoring diagnostic units of a number of objects to be monitored are connected by a network. The center includes an algorithm forming unit for forming algorithms for monitoring, diagnosing, and operating each object to be monitored, a program group formation unit for forming monitoring, diagnostic, and operational programs from these algorithms, a transmitter for transmitting the programs in response to a request from the monitoring diagnostic unit, and a unit for forming information concerning prevention/maintenance form a diagnostic result and monitoring data from the monitoring diagnostic unit of each object to be monitored. The monitoring diagnostic unit of each object to be monitored includes a mobile program execution processor for executing the corresponding object to be monitored, and a transmitter for transmitting monitoring data to the center.

A gas exhaust structure of a battery includes a rupture valve formed in a battery body, and a pipe unit composed by integrating a coupling pipe and an exhaust pipe with each other. A one-side opening of the coupling pipe is coupled to the rupture valve. The exhaust pipe is coupled to an other-side opening of the coupling pipe, guides gas that spouts out from an inside of the battery body through the rupture valve and the one-side opening of the coupling pipe, and exhausts the gas to an outside. The exhaust pipe is arranged to be offset with respect to the rupture valve without allowing an extended line that passes through a center of the rupture valve and a centerline of the exhaust pipe to be perpendicular to each other.

Gas exhaust structure of battery

An elevator including a cage configured to move up and down in a shaft along a guide rail, a plurality of car sheaves installed at a bottom of the cage, a cable placed around the car sheaves and configured to suspend the cage, a hoisting machine having a traction sheave configured to drive the cable, a base extending in a width direction of the cage and configured to support the car sheaves, and a first elastic member disposed between the cage and the base so as to attenuate vibration transferred to the cage.
