摘要： A magnetic tape cartridge includes a cartridge case, a pair of cylindrical hubs rotatably provided in the cartridge case, and a magnetic tape laid between the hubs and wound around outer peripheries of the hubs. Each of the hubs has an inner diameter portion provided with a height-position determining member. The height-position determining member determines a height position of the hub in the magnetic tape cartridge by contacting a driving shaft inserted in the hub when the magnetic tape cartridge is mounted in a magnetic recording and reproducing apparatus.

摘要： A control system for a synchronous machine including a converter for converting DC voltage to AC voltage or AC voltage to DC voltage. The synchronous machine is driven by the converter. The control system further includes a magnetic pole position presuming device for performing a presuming operation to presume a magnetic pole position of the synchronous machine based on high-frequency components of a voltage applied to the synchronous machine and a current flowing into the synchronous machine, and a control device for controlling the converter based on the magnetic pole position presumed by the magnetic pole position presuming device. The control device controls the converter so as to contain significant high-frequency components in the voltage or the current used in the presuming operation when a mean voltage or a mean current output from the converter is spatially in a region close to a straight line containing starting and ending points of non-zero voltage vector output from the converter.
