Abstract: A tool holder holds a cutting tool that cuts a workpiece while revolving about a rotational axis. The tool holder has a fixed part and a cutting part. The fixed part is held by a main shaft of a machine tool. The cutting part is provided integrally with the fixed part and has an asymmetric shape with respect to the rotational axis. The cutting tool is attached to the cutting part. The cutting part has a one-side part and an other-side part. The one-side part has a largest protruding amount from the rotational axis in the cutting part when viewed from an axial direction. The other-side part is located on a side of the rotational axis opposite to the one-side part. A bulk density of the one-side part is smaller than a bulk density of the other-side part.

Abstract: A stator includes a hollow cylindrical stator core comprised of a plurality of stator core segments and an outer cylinder fitted on the radially outer surface of the stator core. The stator core has a recess formed in the radially outer surface and the recess has an engaging wall surface that extends in both the axial and radial directions of the stator core. The outer cylinder has a fastening portion for fastening the outer cylinder to the stator core. The fastening portion is formed to be partially surrounded by a plurality of first slits and a second slit. The fastening portion is bent radially inward to have a second slit-side end part thereof received in the recess of the stator core. Further, the second slit-side end part of the fastening portion has a distal end engaging with the engaging wall surface of the recess of the stator core.

Abstract: An armature for a rotating electric machine includes an armature core and an armature coil. The armature core includes a substantially annular main body disposed in radial opposition to a field of the machine and teeth extending from the main body radially toward the field. The armature coil is arranged between the teeth of the armature core. For each of the teeth, there are formed a protrusion and a pair of claws at a distal end of the tooth. The protrusion protrudes from a circumferentially central part of the distal end of the tooth radially toward the field. The claws extend, respectively on opposite circumferential sides of the protrusion, from the distal end of the tooth toward the field. Each of the claws has a smaller width at its distal end than at its proximal end and is arcuate-shaped so as to engage with and thereby retain the armature coil.

Abstract translation: 用于旋转电机的电枢包括电枢铁芯和电枢线圈。 电枢铁心包括一个基本上环形的主体，其设置成与机器的磁场成径向地相对设置，并且从主体径向向外延伸。 电枢线圈设置在电枢铁芯的齿之间。 对于每个齿，在齿的远端形成有突起和一对爪。 突起从齿的远端的周向中心部径向朝向场突出。 所述爪分别在所述突起的相对的圆周侧上从所述齿的远端朝向所述场延伸。 每个爪在其远端具有比在其近端处更小的宽度，并且是弓形的，以便与电枢线圈接合并由此保持电枢线圈。
