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： An encoder to encode video streams representing a moving picture is provided whose video encoder calculates a bit storage quantity an STD video buffer should have when input of a stream ending with a first picture to the STD video buffer ends, calculates an initial bit storage quantity of a second picture of a stream concatenated to the end of the first picture and starting with the second picture, in a VBV buffer, based on the calculated bit storage quantity of the STD buffer, and encodes the stream based on the bit storage quantity. The video encoder further calculates a bit storage quantity of the STD video buffer, for decoding a picture of the stream in the STD video buffer, calculates, based on the calculated bit storage quantity, a bit storage quantity the VBV buffer should have for ending decoding of a fourth picture of a second stream concatenated to the beginning of a third picture and ending with the fourth picture, and encodes the stream based on the calculated bit storage quantity. With such encoding, a part of video streams can be re-coded without referencing to information indicative of an initial status of a video buffer when editing the video streams.
