A rotary compressor of an embodiment has a rotating shaft, an electric motor, a compression mechanism, a balancer, and a balancer cover. The compression mechanism has a cylinder, a main bearing, and a sub-bearing. The balancer is provided on the rotating shaft on a second side of the sub-bearing in an axial direction thereof. The balancer cover covers the balancer. A lubricating oil supply path that opens on a second side end face in the axial direction is provided in the rotating shaft. A supply hole that allows the supply path to communicate with the outside of the balancer cover is formed in the balancer cover at a position facing the supply path in the axial direction. A seal mechanism that seals between the balancer cover and the rotating shaft is provided between the balancer cover and the rotating shaft while allowing relative movement between the balancer cover and the rotating shaft in the axial direction.

A device state recording system includes a ground system and an on-board system. The device state recording system records a state quantity of a device in the on-board system in response to an instruction from the ground system. The on-board system includes a state recording device provided in the device. A device-side parameter setter sets at least a parameter related to generation of a trigger condition for instructing start of recording of the state quantity of the device, and a parameter related to the state quantity of the device. A state record storage records therein a state quantity of a device that records the state quantity of the device based on the parameter related to generation of the trigger condition and the parameter related to the state quantity of the device.

A state evaluation system includes a sensor, a filter, a signal processor, and an evaluator. The sensor detects elastic waves which are generated from industrial equipment in operation. The filter can pass elastic waves having frequency characteristics based on abrasion which is generated in the industrial equipment. The signal processor extracts a plurality of feature values using the elastic waves passing through the filter. The evaluator evaluates an abnormality of the industrial equipment on the basis of a combination of the extracted plurality of feature values.
