Abstract: A vertical tail of a helicopter has a leading edge and a trailing edge concave toward the leading edge. The helicopter includes a main rotor and a tail rotor for generating anti-torque to cancel torque generated by rotation of the main rotor. The trailing edge is concave within a range within which the vertical tail overlaps a circular region, formed as a rotation range of the tail rotor, in a rotation axis direction of the tail rotor.

Abstract: A light guide 11 of a rectangular cross-section has side faces 11a, 11b including short sides in the longitudinal direction of which one side face 11a is provided with a light-scattering pattern 20, formed by screen-printing in white paint, for scattering the light incident to the light guide 11. The other side face 11b facing the side face 11a is exposed from a casing 12 to serve as a light-emitting surface. In the present embodiment, it is possible to secure a sufficient amount of light because the whole area of the side face is used as the light-emitting surface. The remaining side faces 11c, 11d of the light guide 11 are side faces including the long sides. Since the side faces 11c, 11d easily produce a surface sink during molding, neither the light-scattering pattern 20 nor the light-emitting surface is provided thereon.

Abstract: A light guide 1 is provided at the reverse side thereof with triangular uneven surfaces 1b at a predetermined pitch. The uneven surfaces 1b are integrally formed with the light guide 1 when the latter 1 is injection-molded. Incident light from a light incident plane is caused to be scattered at uneven surfaces 1b within the light guide and to spread in a main scanning direction. The light scattered is emitted from an emission plane. Intensity of light in the main scattering direction can be made uniform by lengthening the uneven surfaces 1b as the uneven surfaces extend from the light incident plane. A position where the light intensity becomes maximum in a sub-scanning direction can be changed by adjusting an angle between the ridgeline of the uneven surfaces 1b and the sub-scanning direction, and distributed characteristics of the light intensity in the sub-scanning direction can be also changed.

Abstract: A light guide 1 is provided at the reverse side thereof with triangular uneven surfaces 1b at a predetermined pitch. The uneven surfaces 1b are integrally formed with the light guide 1 when the latter 1 is injection-molded. Incident light from a light incident plane is caused to be totally reflected within the light guide and to spread in a main scanning direction (the longitudinal direction), wherein the light reaching the uneven surfaces 1b is scattered and caused to be totally reflected at the uneven surfaces 1b. The light scattered and totally reflected at the uneven surfaces 1b is emitted from an emission plane. Intensity of light in the main scattering direction can be made uniform by lengthening the uneven surfaces 1b as the uneven surfaces extend from the light incident plane.
