    • The invention provides a method and an apparatus for forming a plurality of ultraviolet-wavelength laser beams, and a laser machining apparatus, in which the machining efficiency can be improved due to easy maintenance and inspection while deterioration of wavelength conversion means can be prevented to reduce the running cost. A laser beam with a near infrared wavelength output from a laser oscillator is branched into a plurality of laser beams by a laser distribution unit. Each branched laser beam is partially converted into a laser beam whose wavelength is ½ of the near infrared wavelength by a wavelength converter. An ultraviolet laser beam whose wavelength is ⅓ of the near infrared wavelength of the laser beam is formed out of the branched laser beam and the laser beam with the wavelength which is ½ of the near infrared wavelength by another wavelength converter, both the branched laser beam and the laser beam with the wavelength which is ½ of the near infrared wavelength being output from the wavelength converter. The ultraviolet laser beam is extracted and supplied to a portion to be machined, by a wavelength separator.
    • 本发明提供一种用于形成多个紫外波长激光束的方法和装置,以及激光加工装置,其中由于易于维护和检查而可以提高加工效率,同时可以防止波长转换装置的劣化降低 运行成本。 从激光振荡器输出的具有近红外波长的激光束通过激光分配单元分支成多个激光束。 每个分支的激光束被波长转换器部分地转换成其波长为近红外波长的1/2的激光束。 波长为激光束的近红外波长的1/3的紫外激光束由分支激光束和波长为近红外波长的1/2的激光束由另一波长转换器形成, 激光束和波长为近红外波长1/2的波长的激光束从波长转换器输出。 通过波长分离器将紫外线激光束提取并供给到待加工的部分。

    • A rotor structure is to be provided which can diminish stress concentration in teeth-wedge fitting portions located near magnetic poles of a rotor in a rotary electric machine. Teeth 6 have slant faces for abutment against slant faces of wedges 8 to retain the wedges in a fitted state between adjacent teeth, the wedges 8 having slant faces each formed at a predetermined angle relative to the radial direction of a rotor 1, and a circular arc is formed at each slant face rising position in the teeth 6. In this case, the radius of the circular arc formed at each slant face rising position 12 in a preset number of teeth 6 located near magnetic pole portions 7 of the rotor 1 is set larger that of the circular arc formed in the remaining teeth.
