摘要： PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a size reduction and a high performance are realized by improving a cooling method.
SOLUTION: In the rotary electric machine, assuring of a magnetic path by the deflection of a magnetic flux line 25 and enlarging of a region 26 which can be cooled are realized by forming a stator core 23 of a dust core material and adding a collar-like additional region 23a to this stator core 23. The reason why such a constitution is formed is because since a loss heat is generated in response to a magnetic flux in the stator core 23 and simultaneously the heat is added as the current loss of the stator coil 22 itself at the place where the magnetic flux in the stator core 23 is generated around a stator coil 22 from the stator to the magnet of a rotor, it is desired to set a refrigerant channel 26 in the region which surrounds the magnetic flux in the stator core 23. In other words, the stator core 23 is suitable to have the refrigerant channel 26 in the interior or the front surface of the stator core of the region which is not interfered with the dense part the magnetic flux line 25 generated with the stator coil 22, and passing through the interior of the stator core 23.

摘要： PROBLEM TO BE SOLVED: To improve the rigidity of the rotor of an axial motor, and suppress an eddy current generated in the rotor. SOLUTION: For the rotor 14, a plurality of permanent magnets 20 are arrayed apart in the peripheral direction of the rotor, and a pair of poles are constituted of a pair of adjacent permanent magnets 20. To get reluctance torque, the section of a magnetic substance 24 is arranged between each permanent magnet 20 and the next. Since beam-shaped members 30 are arranged among the pairs of poles in the rotational direction of the rotor, the quantity of magnetic flux passing between the beam-shaped members 30 does not change, so it can suppress the eddy current flowing in the beam-shaped member 30.

摘要： PROBLEM TO BE SOLVED: To efficiently cool a rotor of an axial permanent magnet motor, especially a permanent magnet.
SOLUTION: An air channel 36 where a fluid such as air flows is formed between permanent magnets 34 constituting the magnetic pole of a rotor 30. The air channel 36 is provided almost in the radial direction of the rotor 30, and the fluid in the channel flows under the action of a centrifugal force when the rotor rotates. Thus, cooling is carried out near the permanent magnet, which heats more, inside the rotor, and the generated heat is promptly exhausted, while the heat radiation area of the rotor increases for more efficient cooling.

摘要： PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a size reduction and a high performance are realized by improving a cooling method.
SOLUTION: In the rotary electric machine, assuring of a magnetic path by the deflection of a magnetic flux line 35 and enlarging of a region 36 which can be cooled, are realized by forming a stator core 33 of a dust core material and adding a collar-like additional region 33a to this stator core 33. The reason why such a constitution is formed is because since a loss heat is generated in response to a magnetic flux in the stator core 33 and simultaneously the heat is added as the current loss of the stator coil 34 itself at the place where the magnetic flux in the stator core 33 is generated around a stator coil 34 from the stator to the magnet of a rotor, it is desired to set a refrigerant channel 36 in the region which surrounds the magnetic flux in the stator core 33. In other words, the stator core 33 is suitable to have the refrigerant channel 36 in the interior or the front surface of the stator core of the region which is not interfered with the dense part the magnetic flux line 35 generated with the stator coil 34, and passing through the interior of the stator core 33.

摘要： PROBLEM TO BE SOLVED: To provide an axial-type permanent-magnet motor capable of easily being set to suppress generation of cogging torque, while preventing decrease in the torque of the motor.
SOLUTION: In this axial-type permanent-magnet motor, contours 24a, 20a of a coil 24 and a permanent magnet 20 are in such a direction that the direction crosses a rotor rotational direction are set to be approximately a straight-line shape, and the contour 24a of the coil 24 and the contour 20a of the permanent magnet 20 are set so as to contact/separate from each other in a rotor rotating direction in an non-parallel condition, when the rotor rotates. Therefore, when a magnetic pole by the permanent magnet 20 passes through a magnetic pole by the stator coil 24 during the rotation of the rotor, fluctuations in the flux gradually change with the rotational speed of the rotator, so that rapid torque fluctuations are suppressed, and cogging torque is relieved.

摘要： PROBLEM TO BE SOLVED: To provide a structure which can reduce the number of permanent magnets while securing desired motor torque.
SOLUTION: An axial permanent magnet motor includes a rotor having a plurality of the permanent magnets disposed at predetermined intervals along the rotating direction of a rotary shaft so that poles are alternately disposed, and a magnetic element 24 disposed between the permanent magnets 20. Then, when a rotating magnetic field is generated in a stator disposed at a position opposed to the rotor, magnet torque is generated between teeth of the magnetized stator and the permanent magnet 20, and reluctance torque is generated between the teeth and the magnetic element 24. As a result, even if the number of the permanent magnet 20 is reduced and the magnet torque is reduced, it is compensated by the generation of the reluctance torque, and desired motor torque is secured.

摘要： PROBLEM TO BE SOLVED: To provide sample-cutting method for making the effect of the deformation, abrasion or a cut mark of a sample due to cutting hard to act in the depth direction, reducing the mutual interference of the component distributed in the depth direction of the sample or the state, and which is capable of preventing the occurrence of trouble in analysis, and a sample cutting device.
SOLUTION: The sample cutter 10 is constituted so as to cut the sample S at the same time, while cutting the sample S from the surface into the inside by a cutting bite 22, to form an inclined cut surface from the surface of the sample S into the sample at an oblique angle α along the direction (X-axis direction) which crosses the cutting direction (Y-axis direction) at a right angle. Since the positional relation of the edge of the cutting bite 22 with the contact region of the sample S in the depth direction does not change, with respect to the cutting direction, the effect of the deformation abrasion or cutting mark of the sample S due to cutting will not act in the depth direction. As a result, the inclined cut surface, reduced in the mutual interference of the component distributed in the depth direction of the sample S or the state, is formed.

摘要翻译：要解决的问题：为了提供样品切割方法，用于通过切割难以在深度方向上作用而使样品的变形，磨损或切割痕迹的影响，减少分布在样品的深度方向或状态，并且能够防止在分析中出现故障，以及样品切割装置。解决方案：样品切割器10被构造成同时切割样品S，同时通过切割咬合部22将样品S从表面切割到内部，从而从样品S的表面形成倾斜的切割面将样品S沿与切割方向（Y轴方向）成直角的方向（X轴方向）以倾斜角α成为样品。由于切削咬合22的边缘与样品S的深度方向的接触区域的位置关系相对于切割方向没有变化，所以样品S的变形磨损或切割痕迹的影响由于切割不会在深度方向上起作用。结果，形成了沿着样品S的深度方向分布的部件的相互干涉减小的倾斜切割面或状态。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of coil cooling by effectively transmitting the heat that a coil generates to the iron core of a stator.
SOLUTION: Smoothing is performed for a face at which the bundle 14a of coils contacts with a stator iron core (b). For this smoothing, it will do to process it to such a degree that it does not break the insulating film 18 of a rectangular coil 16, leaving an insulating material at the smoothed face of the bundle 14a of coils, or it will do to process it so far as to remove the insulating film 18 of the rectangular coil 16, and then to form an insulating film on this processed face. As regards the formation of the insulating film on the smoothed face, it will do to so form an insulating film 19 as to cover the entire bundle 14a of coils by wrapping, for example, an insulating tape, etc. (c), or it will do to form an insulating film 20 anew only on the smoothed face (d). Since the bundle 14a of coils where smoothing is applied can transmit heat efficiently when contacting with the stator iron core, the efficiency of coil cooling is improved.
