Abstract: A hair cutting device of the present disclosure comprises an optical waveguide and a holding member that holds the optical waveguide. The optical waveguide comprises a light irradiator. The light irradiator irradiates hair protruding from skin with light to cut the hair. The holding member holds the optical waveguide in such a way that the light irradiator is exposed from at least one surface. As a result, even when the hair or the skin comes in contact with the light irradiator, misalignment or the like of the optical waveguide hardly occurs. This results in the improved hair cutting device being provided.

Abstract: A hair cutting device according to the present disclosure comprises an optical waveguide. The optical waveguide comprises a light irradiator. The light irradiator irradiates hair protruding from the skin with light to cut the hair. The refractive index of the light irradiator is smaller than the refractive index of the surface of the skin. As a result, options such as the material of the optical waveguide and the like can be increased. Furthermore, for example, when the skin is appropriately irradiated with light from the light irradiator, an action on the skin such as sterilization or activation can also be expected.

Abstract: A hair cutting device according to the present disclosure comprises an optical waveguide. The optical waveguide comprises a light irradiator for irradiating hair protruding from a skin with light to cut the hair. At least at a time of cutting the hair, a power density of light passing through the optical waveguide is more than or equal to 50 kW/cm2. This makes it easy to efficiently cut hair with light with which the light irradiator irradiates the hair. That is, it is possible to apply sufficient light energy for cutting the hair from the optical waveguide to the hair, and it is possible to cut the hair in a relatively short time. Therefore, for example, a width increases such as a thickness or hardness of hair that can be cut.

Abstract: In a DC-excited synchronous electric motor in which a field system is excited by using an exciting core, in order to obtain large torque density and output density, the effective area of air gaps, through which an armature and a field system face each other, is increased. The armature of a stator 300A (300B) is arranged to face a side surface in a radial direction and two side surfaces in an axial direction of the rotor 200A (200B), with air gaps, respectively. By supplying multiphase AC current from an inverter to the armature, rotating magnetic fields having the same polarity spatially and temporally are generated. Thereby, a torque and a rotation output in the same rotating direction are obtained in three air gaps G1 to G3.
