  • Patent number: 10235658
    Abstract: The maintenance management device 3 includes an error status diagnosis unit 11, a grace period estimation unit 14, a maintenance cost estimation unit 15, and a screen display unit 17. When the error status diagnosis unit 11 has diagnosed the occurrence of an anomaly, the grace period estimation unit 14 estimates a first grace period leading up to the occurrence of a failure. The maintenance cost estimation unit 15 estimates the cost of corrective maintenance incurred when the failure occurs after the elapse of the first grace period. The screen display unit 17 displays a combination of the first grace period and the cost of corrective maintenance. Alternatively, the grace period estimation unit 14 estimates a second grace period over which preventive maintenance may be postponed without a failure.

  • Patent number: 10073447
    Abstract: In industrial machine abnormality diagnosis, if the machine is diagnosed to have abnormality, then sensor data from the machine needs to be sent to a management center for causal analysis. However, since machines operated at a remote site cannot always communicate with a management center, it has been found that, in some cases, sensor data that has failed to be sent from a machine remains in the memory of the machine, resulting in lack of available memory capacity. In view of this, the present invention determines beforehand whether the diagnosed machine will run out of available memory capacity before the completion of sending the amount of sensor data required for causal analysis for the machine, and instructs a maintenance person to recover memory.

  • Publication number: 20180234746
    Abstract: Sensor data immediately after the issuance of an alarm does not exhibit the peculiarity of a failure, with the result that the wrong component is sometimes erroneously identified as the failure component. A failure component identification unit provided in a maintenance device collects an alarm issued when a measurement value exceeds a range of a measurement threshold value in an apparatus being a maintenance target. The failure component identification unit identifies the failure component on the basis of the measurement value exhibiting a condition indicating a peculiarity of the failure. An identification reliability determination unit determines the reliability of the component identification result obtained by a failure component identification unit.

    Abstract: In a metal oxide film formation method of the present invention, the following steps are performed. In a solution vessel, a raw-material solution including aluminum as a metallic element is turned into a mist so that a raw-material solution mist is obtained. In a solution vessel provided independently of the solution vessel, a reaction aiding solution including a reaction aiding agent for formation of aluminum oxide is turned into a mist so that an aiding-agent mist is obtained. Then, the raw-material solution mist and the aiding-agent mist are fed to a nozzle provided in a reactor vessel via paths. Thereafter, the raw-material solution mist and the aiding-agent mist are mixed in the nozzle so that a mixed mist is obtained.

  • Publication number: 20170307480
    Abstract: To improve diagnostic accuracy in diagnosing for abnormality of a machine, it is necessary to adjust a parameter regarding diagnosis such as the number of clusters. In such an adjustment operation, each time a diagnostic parameter is modified, a checking operation by an analysis operator is required to see whether a diagnosis result has been improved. The present invention assists in the checking operation to see whether diagnostic accuracy has been improved by comparing diagnosis results before and after parameter modification. If there are many items of sensor data for diagnosis, many items of abnormality degree data arise as analysis result. Many items of data pose a problem that comparing diagnosis results takes time. In the data display system, abnormality degree data that has changed largely before and after parameter modification is automatically found and displayed to the analysis operator. How much an abnormality degree has changed is determined as an abnormality degree change rate, i.e.
