A synchronous machine control device includes a flux command generator, a magnetic flux estimator, a divider, a flux controller and \u03b3- and \u03b4-axis armature current controllers. A user may select an initial target scale size and use an aiming mark to align a rangefinder with the object before determining the range. An optical disc apparatus interprets the file information and buffering information and then carries out a series of operations storing and reading out and playing the additional audio data in a way suitable to the buffering area allocated within a buffer. Another non-limiting embodiment includes instantiating a plurality of replication sender threads, where the replication sender threads communicate in parallel with respective replication servers over respective replication paths. Either the legs or body may be braided first. The treatment portion further includes a hydrophilic region which is formed by the application of a hydrophilic coat and which is provided in part of the circumferential surface of the treatment portion to be provided from the treatment region to an end portion of the treatment portion located in the distal end opening portion in a longitudinal axis direction.
