Abstract: An AE signal is acquired from an AE sensor disposed on a fixed part of the rotating machine, and the presence or absence of rubbing in the rotating machine is determined, based on the AE signal. As a result, if the rubbing is determined to be present, a rubbing suppression operating condition imposed on control of the rotating machine is decided to suppress the rubbing.

Abstract: A disk-storing disk may include multiple supporting members for supporting disks and being stacked in the axial direction; a supporting member selecting mechanism for moving a supporting member to a selecting position; a driving unit having a rotational driving unit for clamping and rotating a disk held by the supporting member at the selecting position; a transporting mechanism for transporting a disk inserted from an insertion opening of the casing to the selected supporting member at the selecting position; and a restriction guide member having a restriction face and being turnably supported between a guiding attitude and a non-acting attitude; wherein, when a disk is transported toward a supporting member at the selecting position by the transporting mechanism, the restriction guide member turns to the guide attitude, and when the supporting member is moved by the supporting member selecting mechanism, the restriction guide member turns to the non-acting attitude.

Abstract: A disk-storing disk device is disclosed. A disk-storing disk device may include: a plurality of supporting members for supporting a disk and disposed stacked in the axial direction of the disk; a supporting member selecting mechanism for spreading the spacing between selected and adjacent supporting members; and holding members moveably supported by each of the supporting members, the holding members for holding a disk between the holding members and each of the supporting member when the supporting member selecting mechanism moves the plurality of supporting members in the axial direction of the disk.

The disk-storing disk device includes: a driving unit for rotating a disk; a plurality of supporting members for supporting a disk and disposed stacked in the axial direction of the disk; a supporting member selecting mechanism for spreading the spacing between selected and adjacent supporting members; a motive force transmission mechanism for moving the driving unit from a retracted position away from the perimeter of a disk supported by a supporting member to an intervention position for clamping the disk; and holding members for holding a disk between the holding members and the supporting member; wherein following the driving unit being moved to the intervention position from the retraction position by the motive force transmission mechanism, the holding members are moved from the holding position to a position where holding of the disk is disengaged, by the motive force of the driving source of the motive force transmission mechanism.

Abstract: A disk device has a driving unit supported by elastic members. In a standby state, locking of the driving unit by a lock member is disengaged, so that the driving unit is elastically supported by dampers and a coil spring. This reduces the time of restriction by pins, thereby preventing damage to the pins. The lock member is operated at the time of receiving a disk, thereby locking the driving unit. Thus, the driving unit does not need to be locked in the casing for prolonged periods of time.
