    Abstract: A manufacturing method of manufacturing an iron core includes connecting a plurality of iron core pieces each including a tooth portion and a yoke portion in a strip shape, connecting the iron core pieces adjacent to each other by a connection portion, and forming a continuous iron core piece provided line-symmetrically with reference to the connection portion. A laminated body is formed by bending and superimposing the iron core pieces adjacent to each other while the connection portion is used as a symmetry axis. A pressure is applied in a laminating direction of the laminated body to fix the laminated body, and a coil is provided in the tooth portion. In this manner, it is possible to realize a manufacturing method of an iron core, which have a high material yield, high productivity, and excellent magnetic properties by using a thin iron core piece.

    Abstract: An iron core including a laminate of a plurality of fixed electromagnetic steel sheets, a laminate of alloy thin strips which is sandwiched between the laminate of the electromagnetic steel sheets, a fastening mechanism which penetrates the laminates of electromagnetic steel sheets and alloy thin strips, and a fixing base. The laminate of alloy thin strips reduces compressive and torsional forces acting on the laminate of alloy thin strips by using the iron core having a structure in which upper and lower portions of a laminate of alloy thin strips having nanocrystal grains are sandwiched together with laminates of amorphous alloy thin strips. Furthermore, a motor including a rotor and the above-described iron core is used.

    IPC: F21V8/00

    Abstract: A light emitting device includes a light source and a waveguide structure. The light source emits light having a directionality. The waveguide structure includes an optical waveguide and an exterior part. The optical waveguide has an incident end surface and an emission end surface, converts a wavelength of the light incident from the incident end surface, and emits the light from the emission end surface. The exterior part is optically transparent and covers the optical waveguide such that the incident end surface and the emission end surface are exposed from the exterior part. The optical waveguide is elongated in a length direction. The length direction of the optical waveguide is inclined at a predetermined angle with respect to an optical axis of the light in a predetermined plane including the length direction of the optical waveguide and the optical axis of the light. The predetermined angle is set to allow the light to propagate in the optical waveguide with total internal reflection at a boundary surface between the optical waveguide and the exterior part.

    Abstract: A light emitting device includes a light source that emits light having a directivity from a light emitting surface of the light source, a waveguide structure that includes an optical waveguide having an inlet facing the light emitting surface, and a peripheral wall protruding from the inlet toward the light emitting surface, and a lens that is provided between the light emitting surface and the inlet. The peripheral wall has an inner surface surrounding the inlet. The peripheral wall has a first opening closer to the light emitting surface and a second opening closer to the inlet. The first opening is larger than the second opening. The peripheral wall includes a narrow opening portion in which an internal space of the peripheral wall is smaller than the lens when viewed from a direction of an optical axis of the light. The inner surface of the peripheral wall includes an inclined surface that inclines so that the internal space becomes narrower as approaching the inlet, at least in the narrow opening portion. The lens is disposed in contact with the narrow opening portion in the internal space of the peripheral wall.
