  • Optical connection structure, optical connector, and optical connecting method
    Patent number: 12248185
    Abstract: An optical connection structure including first optical fibers, second optical fibers, a first optical connector, and a second optical connector is disclosed. The first optical connector is configured such that each of first distal end portions of the first optical fibers protrudes from a first front end surface to the outside when the first optical connector and the second optical connector are connected to each other. Each of the first distal end portions is inserted into a corresponding second fiber hole of the second optical connector. The second optical connector is configured such that each of second distal end portions of the second optical fibers is moved rearward inside second fiber holes due to each of the first distal end portions respectively inserted into the second fiber holes. The first optical fibers and the second optical fibers are optically coupled to each other inside the second fiber holes.

  • Vehicle lamp
    Patent number: 8393772
    Abstract: A vehicle lamp includes a lamp body having an opening, a resin cover attached to the opening to form a lamp chamber together with the lamp body; and a light source disposed inside the lamp chamber to irradiate light through the resin cover. The resin cover includes a design surface portion, and a peripheral edge portion surrounding the design surface portion. The peripheral edge portion includes a gate mark, and a thick-walled portion having a greater wall thickness than the other part of the peripheral edge portion and extending from the gate mark toward the design surface portion.
