  • Publication number: 20220407393
    Abstract: Provided is an inspection device for a rotating electric machine, the inspection device including a photographing device, a drive mechanism, a display, and a controller. The photographing device photographs a pattern formed on a surface of a wedge constituting part of an armature. The drive mechanism moves the photographing device with respect to a stator functioning as the armature. The controller detects strain of the wedge by comparing image data of the pattern photographed by the photographing device with reference data of the pattern. In this manner, the inspection device for a rotating electric machine can easily detect the strain of the wedge. Further, the controller estimates loosening of the wedge based on the strain of the wedge, and informs an operator of the rotating electric machine through the display that the loosening of the wedge has occurred.

  • Patent number: 11435238
    Abstract: A temperature detection device includes: a detection processing unit configured to transmit a transmission radio wave, simultaneously receive a response radio wave corresponding to the transmission radio wave, and detect whether a temperature of an object to be measured is normal or abnormal based on the response radio wave; and a temperature sensing unit configured to receive the transmission radio wave and transmit the response radio wave responding to the transmission radio wave. The detection processing unit calculates, from the response radio wave received via a second antenna, an amplitude, a phase, or a quadrature phase amplitude of the response radio wave and compares the temperature of the object to be measured to a temperature determined in advance based on a result of the calculation.

  • Patent number: 11308986
    Abstract: In an approach to automatically reconciling data in HSM without affecting system performance, responsive to migrating a file on a hierarchical storage system from a primary storage to one or more tape drives, one or more file migration records are recorded in a reconcile database. Responsive to the occurrence of a file event on the primary storage, the one or more file migration records in the reconcile database are updated. Responsive to receiving a command to unmount a first mounted tape on one of the one or more tape drives, a reconcile function is performed on the first mounted tape, wherein the reconcile function updates the first mounted tape with the one or more file migration records in the reconcile database.

  • Patent number: 11281691
    Abstract: Mechanisms are provided for performing a data replication operation to replicate data from a first data processing system to a second data processing system. The mechanisms store a compression ratio history in association with data to be replicated. The compression ratio history stores one or more compression ratios for one or more previously executed data replication operations. The mechanisms determine whether a data compression operation should be applied to the data for a current data replication operation based on the compression ratio(s) in the compression ratio history. In response to determining that data compression should be applied to the data, the data compression operation is performed and the compressed data is replicated to the second data processing system. In response to determining that data compression should not be applied, the data is replicated without compression.
