摘要： A stator coil is configured of a first group of six turns of conductive wire, and a second group also of six turns, with the first group of six turns being wound on a spool, leaving a gap the same as the diameter of the conductive wire between winds. Upon completion of winding the first group, the winding is turned back, and the second group of six turns is wound in the gap, so as to be adjacent to the turns of the first group. The article is then inserted into a slot in a stator core of a stator, thereby configuring a stator coil. This provides for a rotating electrical machine and manufacturing method thereof with improved insulation resistivity regarding inverter surge voltage, and moreover high output can be obtained with a machine of comparable external dimensions with conventional machines.

摘要： FIG. 3B shows buffer occupancy rate of a transport stream buffer 21 when a TS packet is transferred to the transport stream buffer 21 having a transport rate Rt and a leak rate Rx. A time T1 during which the buffer occupancy rate of the transport stream buffer 21 increases and a time T2 during which the buffer occupancy rate of the transport stream buffer 21 decreases are expressed by (Rt−Rx)×T1=Rx×T2 and T1=(188×8)/Rt. A time T is T=T1+T2=(188×8)/Rx. Therefore, the time T is equal to a time T′ shown in FIG. 3C. Thus, when a TS packet is transferred in a cycle of the time T′, the transport stream buffer 21 will not overflow and the transport stream buffer 21 becomes empty at least once a second, whereby simulation for the transport stream buffer 21 is not required in the simulation for the T-STD model.
摘要翻译：图。图3B示出了当TS分组被传送到具有传输速率Rt和泄漏速率Rx的传输流缓冲器21时的传输流缓冲器21的缓冲器占用率。传输流缓冲器21的缓冲器占用率增加的时间T1和传输流缓冲器21的缓冲器占用率减小的时间T2由（Rt-Rx）xT1 = RxxT2和T1 =（188×8）表示， / Rt。时间T为T = T1 + T2 =（188x8）/ Rx。因此，时间T等于图1所示的时间T'。 3C。因此，当在时间T'的周期中传送TS分组时，传输流缓冲器21将不会溢出，并且传输流缓冲器21至少一秒钟变空，由此不需要传输流缓冲器21的模拟在T-STD模型的模拟中。
