  • Patent number: 11950333
    Abstract: Light (light (L1)) at peak luminous intensity in a light distribution of a first region (12a) of a light-irradiating surface (12) is sent to a first region (32a) of a target surface (32) via a first region (22a) of a reflecting surface (22). Light (light (L2)) at peak luminous intensity in a light distribution in a second region (12b) of the light-irradiating surface (12) is sent to a second region (32b) of the target surface (32) via a second region (22b) of the reflecting surface (22). An optical distance from the first region (12a) of the light-irradiating surface (12) to the first region (32a) of the target surface (32) via the first region (22a) of the reflecting surface (22) is greater than an optical distance from the second region (12b) of the light-irradiating surface (12) to the second region (32b) of the target surface (32) via the second region (22b) of the reflecting surface (22). The luminous intensity of the light (L1) is higher than the luminous intensity of the light (L2).

  • Patent number: 10562140
    Abstract: A press-fitting jig for a closure cap which is configured to press-fit a closure cap into a bolt mounting hole formed in a track rail of a guide device. The press-fitting jig is mounted to a moving block, which is assembled to the track rail through intermediation of a plurality of rolling elements and is configured to move on the track rail. The press-fitting jig includes: a finishing surface which is brought into slide contact with an upper surface of the track rail having the bolt mounting hole opened therein; and a guide surface, which is formed adjacent to the finishing surface and forms a wedge-shaped space with the track rail in a longitudinal direction of the track rail, the guide surface being configured to push the closure cap temporarily placed in the bolt mounting hole into the bolt mounting hole along with movement of the moving block.
