Abstract: A bearing test method and a bearing test device are provided for bearings in which a non-contact state is maintained between a shaft element and a bearing element in a normal rotation state. In addition, a motor bearing monitoring device is provided to detect an abnormality in a motor or that a motor's life is near its end, where the motor utilizes the bearing. Furthermore, a storage device such as a hard disk drive equipped with the motor monitoring device is provided. For a bearing that can retain a shaft element and a bearing element coaxially positioned in a non-contact state when the number of revolutions exceeds a predetermined number of relative revolutions, a bearing test method is provided to determine whether the shaft element and the bearing element are in a contact rotation state.

Abstract: A system which performs heating or the like with respect to a workpiece in a production system for a mechanical product such as a motor, and a production system including this system, for decreasing line inventories, continuously maintaining the cleanliness, and decreasing an installation space. The system comprises: a carriage device (41a, 41b) which is arranged in an oven (40) capable of accommodating a plurality of workpieces (2) and carries each workpiece (2) to a supply side or a discharge side in the oven (40); and a control portion which controls the carriage device (41a, 41b). The carriage device (41a, 41b) is operated in accordance with each workpiece (2), and heat treatment statuses of the workpieces (2) are individually managed in the oven (40). The carriage device (41a, 41b) is set in such a manner that an operation drive device (43) as a drive mechanism thereof is positioned outside the oven (40) and only an operation end (41a) which holds the workpiece (2) enters the oven (40).

Abstract: A cleansing system for automatically cleansing a workpiece through cleansing tanks and drying tanks in steps to process and assemble the workpiece, an ultrasonic cleansing apparatus, a vacuum drying apparatus, a cleansing apparatus, a cleansing tank, a drying tank and a production system. For example, a descending air current with a sufficient wind velocity/air capacity is obtained, a cleansing time is reduced and unevenness in cleansing of the workpiece is suppressed without bringing contaminations in a preceding tank into a following tank. The present invention has a carriage device (21) which carries a workpiece (2) to a predetermined position, a plurality of workpiece processing portions (23) arranged around the carriage device (21) in a radial pattern, a drive portion which drives the carriage device (21), a workpiece supply portion (25) which supplies the workpiece (2), and a workpiece discharge portion (26) which discharges the workpiece (2).

Abstract: A production system which can provide an operating environment consisting of a clean atmosphere when an environment which can prevent dust from entering is required in an operation such as processing, assembling or the like of a workpiece.

Abstract: With an operation handle arranged in the neighborhood of e.g. a microscope for operation as an appliance to be supported attached to the tip of plural arms rotatably coupled with one another, the operation force applied to the operation handle is detected as a signal in directions of plural axes by a force/torque sensor, the detected force/torque information in each of the directions of the plural axes is impedance-control and track-control to compute an operation command for each joint in the plural arms, and on the basis of the operation command for each joint, the plural arms are moved in the direction of the operation force.

Abstract: An automatic transaction apparatus comprises a media operation unit having a card access port and paper currency depositing/receiving port and a housing unit which includes a card process portion and a plurality of paper currency dispenser portions which are positioned at the side of the card access port and the paper currency depositing/receiving port. Also included are a slider portion which is arranged to be movable in a given direction behind the card access port and the paper currency depositing/receiving port and in front of the card process portion and the plurality of paper currency dispenser portions. Further included are a transport unit which is supported by the slider portion, and which has a chuck portion which is movable between the operation unit and the housing unit. A controller also forms part of the apparatus; the controller controls movement of the slider portion and the chuck portion.
