摘要： A rotation angle detector includes a stator core (2) comprised of a plurality of core sheets (4) each having plural core members (4a) each including a tooth and a yoke portion (5a, . . . , 5h, 4b) disposed in a strip-like array with adjacent core members being coupled to one another by coupling means (4d) at yoke end portion. The core member is laminated. The stator core is shaped into an annular form by bending the core members at coupled portions so that the tooth portions extend centrally while capable of extending substantially linearly upon expansion thereof. An exciting winding (8) and output windings (9, 10) of n phases are wound on the tooth portions. A rotor core (3) is disposed rotatably relative to the stator core such that gap permeance between the rotor core and the tooth portions changes sinusoidally as a function of the rotation angle.
摘要翻译：旋转角度检测器包括由多个芯片（4）组成的定子芯（2），每个芯片具有多个芯构件（4a），每个芯构件包括齿和轭部（5a，...，5h，4 b）设置在条状阵列中，相邻的芯部件通过轭铁端部处的联接装置（4d）彼此耦合。芯构件被层压。定子芯通过在耦合部分处弯曲芯部构件而成形为环形，使得齿部中心延伸，同时能够在其膨胀时基本上线性地延伸。激励绕组（8）和n相的输出绕组（9,10）缠绕在齿部上。转子芯（3）相对于定子芯可旋转地设置，使得转子芯与齿部之间的间隙磁导通过旋转角度的正弦变化而变化。

摘要： A small-sized and inexpensive electric motor in which connection of a stator coil is easy, the connecting portion occupies a small space, and stable torque characteristics are obtained by making electric resistance uniform. A coil bobbin is mounted on a magnetic pole of a stator core, and a stator coil is fitted. A lead wire is led to an external diameter side of one end of the stator core. A connecting conductor holder with a common coil-connecting conductor, connecting conductors for each phase and a through hole is mounted on an end of a coil bobbin. The common coil-connecting conductor has connecting terminals projecting in radial directions, and the connecting conductors for each phase have such a cross-sectional area as to equalize electric resistance of each phase after connecting the stator coil. The through hole is formed to allow a bearing-housing portion to be inserted.

摘要： Provided is a wave-power generator capable of adjusting a natural period (natural frequency) in response to a changing wave period. The wave-power generator includes a weight that is installed in a floating body via a spring and that linearly reciprocates in response to a fluctuation of a water surface and a generator that generates power by being driven based on the linear reciprocating motion of the weight. An additional-mass body for adding a mass to the mass of the weight is further included.
