摘要： A marker (10) includes a lenticular lens (11) formed from a translucent material to have a plurality of convex portions (13) positioned to line up in, for example, at least one direction. The optical axes (OA1) of the convex portions (13) all intersect with an optical reference point (OP) on the product optical axis (PA). The optical axes (OA1) of the convex portions (13) are all orthogonal with and pass through the center of the bottom surfaces of grooves (14). Colored portions (15) are accommodated in the grooves (14).

摘要： This optical receptacle has a first optical surface on which light emitted from a light-emitting element is incident; a light splitting unit which splits the light incident on the first optical surface into monitor light that travels toward the detecting element and signal light that travels toward the cross-section of the optical transmission body; a second optical surface which emits the signal light split in the light splitting unit toward the cross-section of the optical transmission body; and a third optical surface which emits the monitor light split in the light splitting unit toward the detection element. The first optical surface causes the light incident thereon to converge so that the beam waist is positioned in the optical path between the first optical surface and the second optical surface.

摘要： A display has a member irradiated by a surface light source device comprising a light diffusion member and emission device. The emission device is provided with a light flux control member having a recess and light control emission face which is configurated so as to satisfy Conditions 1 and 2 in a range at least covering a half-intensity-angular-range. Light emitting element(s) may be sealed. Condition 1 is that relation θ5/θ1>1 is satisfied except for light emitted from a light emitting element toward within an angular-neighbourhood of a standard optical axis of the emission device, and Condition 2 is that value of θ5/θ1 decreases gradually according to increasing of θ1, where θ1 is an emission angle of any light at being emitted from the light emitting element, and θ5 is an emission angle of that light of θ1 at then being emitted from the light control emission face of the light flux control member.

摘要： This light-emitting device has a light-emitting element and a light flux control member. The light flux control member has an entry surface, a light control surface, a back surface, and a ring-shaped groove. The light control surface includes a first transmission portion, a total reflection portion, and a second transmission portion. The ring-shaped groove includes a first inner surface and a second inner surface. A second light beam, which is a light beam that is part of the light beam emitted from the light-emitting center of the light-emitting element, enters the interior of the light flux control member at the entry surface, is totally reflected at the total reflection portion, then internally reflected at the second inner surface, and exits from the second transmission portion to the exterior of the light flux control member.

摘要： A reflection member includes at least one polygonal cell having a polygonally-shaped center bottom part in which a light source is disposed, vertex-part inclined surfaces provided so as to correspond to the respective vertexes of the polygonal shape, and side-part inclined surfaces provided between the corresponding vertex-part inclined surfaces, such that an inclination angle α of at least a part of the vertex-part inclined surfaces to the center bottom part is larger than an inclination angle β of the side-part inclined surfaces to the center bottom part.

摘要： In a nozzle plate of the present invention, a part of fuel flowing out from a fuel injection port of a fuel injection device is atomized by colliding with an interference body, is rapidly bent in a flowing direction, and collides with the fuel that is flowing straight through a nozzle hole and an orifice to make the fuel that flows straight through the nozzle hole and the orifice turbulent. The orifice includes a corner portion which is defined by an outer edge portion of the interference body and has a pointed shape without roundness at a part of an opening edge. The corner portion makes an end portion of a liquid film of the fuel passing through the orifice into a pointed shape for ease of atomization by friction with air.

摘要： The first light flux control member comprises: a concave first entrance surface, facing the plurality of light-emitting elements; and a first exit surface, and an outer exit surface. The second light flux control member controls and causes the light exiting from the first light flux control member to become oriented in the direction along the first central axis. In addition, when f represents the focal distance of the first light flux control member, and d represents the distance between the first central axis and the optical axis in the light-emitting element farthest from the first central axis, the surface light source device satisfies −0.6

摘要： This emitter has an emitter body, a film, and a cover. A sealed space is formed between the cover and a portion of the film. A flow channel in the emitter include: a first through-hole that is opened in a first surface and a second surface of the emitter body; and a second through-hole that is disposed downstream of the first through-hole. The film is disposed so as to block first surface-side openings of the first through-hole and the second through-hole. The film becomes distorted toward the side of the sealed space due to deformation caused in the film when the temperature of the film exceeds a preset value and when the pressure of irrigation liquid circulating within the flow channel exceeds a preset value, thereby creating a gap between the emitter body and the film, through which the first through-hole and the second through-hole are enabled to be connected.
