Abstract: A magnetic geared motor includes a stator including a plurality of teeth that produce a magnetomotive force, a first rotor that rotates by the magnetomotive force of the stator, and a second rotor that, in response to rotation of the first rotor, rotates at a lower speed than the first rotor. The first rotor, the second rotor, and the stator are disposed coaxial to each other, and a plurality of magnets of different polarities are disposed in respective slot openings present between each two adjacent teeth.

Abstract: A resin filler tube includes: a tubular body; a flange having a diameter greater than an outer diameter of the tubular body, a thickness greater than a thickness of the tubular body, and a predetermined width in an axial direction, and having a first axial end face forming a weld surface to be welded to an outer circumferential edge of an opening hole of a fuel tank; and a base-end-side reverse tapered portion which connects between an end of the tubular body on the fuel tank side and an end of an outer circumferential surface of the flange on a side opposite to the fuel tank side, and which is reversely tapered so as to increase a diameter toward the flange. The base-end-side reverse tapered portion has an inner diameter that is not less than an inner diameter of the tubular body over an entire range in the axial direction.

Abstract: A three-dimensional display device including a diffraction sheet including a transparent substrate, and a diffraction layer having a first diffraction pattern formed in a first array pattern and a second diffraction pattern formed in a second array pattern on the transparent substrate, the diffraction sheet measuring 10 inches or more in diagonal; one of a liquid crystal device having a plurality of pixels and a color filter having a plurality of types of color filters; and a light source. The first diffraction pattern and the second diffraction pattern are overlapped with the pixels or the color filters in a direction normal to the diffraction sheet with an amount of displacement being 1/10 or less of a pitch of the pixels or the color filters.

Abstract: A fuel filler structure includes a base member, a shutter member, a seal part, and an opening part. The base member includes a fuel filler port and a fuel filler port outer circumferential part which is provided outward further than the fuel filler port. In the shutter member, an opening-closing valve is supported movable to a closed position and an open position. The seal part is arranged between the fuel filler port outer circumferential part and the opening-closing valve when the opening-closing valve is located at the closed position. The opening part connects together an outer surface and an inner surface of the fuel filler port outer circumferential part, and a second opening end of the opening part is arranged at a position that overlaps the opening-closing valve when the opening-closing valve is located at the closed position.

The base-end-side reverse tapered portion has an inner diameter that is not less than an inner diameter of the tubular body over an entire range in the axial direction.

Abstract: A negative electrode for use in an iron-air secondary battery of the present invention comprises a three-dimensionally formed structure in which particles of metal powder comprising iron or an iron alloy as a principal component are coupled to each other through metallic bonding, wherein the negative electrode has a porosity of greater than or equal to 30% and less than or equal to 70%. A production method of a negative electrode for an iron-air secondary battery of the present invention comprises: mixing with a resin, metal powder comprising iron or an iron alloy as a principle component; molding a mixture obtained after the mixing; and sintering a molded body obtained after the molding.
