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： An edit point of an earlier GOP1 is placed after an I picture I22. In addition, the edit point is not placed immediately after an I or P picture. Thus, the GOP1 is decoded. A stream placed after the edit point (a P picture and later pictures) is discarded. B pictures B26 and B27 placed after a P picture P25 are re-encoded with a forward moving vector Fw. The remaining pictures other than B pictures B26 and B27 are re-encoded with encoding information used in a decoding process. Since an edit point of a later GOP2 is not placed before the I picture I2, the GOP2 is decoded. A stream placed before the edit point (pictures B0 to P5) is discarded. The first P picture P8 is changed to an I picture. Thereafter, the re-encoding process is performed. The P picture P8 changed from the I picture is used as a predictive reference picture. With the P picture P8, a backward moving vector Bk is obtained. With only the moving vector Bk, the B pictures B6 and B7 placed before the P picture P8 are re-encoded.
摘要翻译：较早GOP1的编辑点放置在I图片I22之后。另外，编辑点不会立即放置在I或P图像之后。因此，GOP1被解码。放置在编辑点之后的流（P图片和更晚的图片）被丢弃。放置在P图像P25之后的B图像B26和B27用前向移动矢量Fw重新编码。除了B图像B26和B27之外的其余图像被用解码处理中使用的编码信息重新编码。由于稍后GOP2的编辑点未放置在I图像I2之前，因此对GOP2进行解码。放置在编辑点之前的流（图B0至P5）被丢弃。第一个P图像P8被更改为I图像。此后，执行重新编码处理。从I图像改变的P图像P8用作预测参考图像。利用P图像P8，获得向后移动矢量Bk。只有移动矢量Bk，放置在P图像P8之前的B图像B6和B7被重新编码。

摘要： A large peeling force due to heat occurs at the boundary between the insulation coating over the coil end and the coil conductor when the stator coil emits heat and reaches a high temperature due to the high output of the rotating electric machine that causes the insulation coating to peel from the conductor consequently causing insulation defects. A sloped surface is formed on the insulation coating so that the thickness of the tip of the insulation coating on the coil end has a shape having a slope that becomes gradually thinner towards the welded coupling section made by welding the conductor.
