Abstract: An optical module that has a structure ensuring reduction in size. The optical module has a structure where a part of a fiber block is protruded from a housing. By including a thin plate, this optical module can avoid entering of dust in the housing, allows a position shift of the fiber block due to a mounting position error of an optical component in the housing, a position shift of an opening portion due to a dimensional error of the housing, or a displacement due to a temperature change, and can reduce the coupling loss due to the optical axis misalignment.

Abstract: Provided is a washer liquid supply system in a simple structure and capable of improving the capacity of washing an object of a vehicle. A washer liquid supply system includes: a washer tank mounted on a vehicle to store washer liquid; a supply section mounted on the vehicle to supply the washer liquid in the washer tank to a window shield of the vehicle; and a connecting member being a bubbling section mounted on the vehicle to make the washer liquid contain bubbles, wherein the supply section supplies the washer liquid containing the bubbles to the window shield.

Abstract: An optical circuit board which is mounted with a loop-back circuit for returning aligning light to the fiber array in the vicinity of the fiber array connection end. Since an aligning loop-back circuit can be formed in an optical waveguide pattern, a production cost does not increase in comparison to an optical circuit board of the related art. The aligning light combined from the optical fiber to the aligning port of the optical circuit board is returned to the optical fiber around the loop-back circuit. Therefore, it is possible to perform alignment using the returned light. That is, alignment can be performed while being mounted on a package without installing a light-reflecting film or mirror.

Abstract: A washer tank is mounted on a vehicle and stores washer fluid. A first tilted portion tilted upward toward an inner side of the washer tank is formed on an inner surface of a side wall portion of the washer tank.

Abstract: A distribution apparatus installed in a washer liquid passage has an intake passage which reciprocates in a circumferential direction of a circle about a pivot shaft in a linked manner with a wiper arm and to which a washer liquid is supplied, a first ejection passage disposed further outside in a radial direction of the circle than the intake passage and disposed at a position offset toward one side in the circumferential direction with respect to the intake passage, and a second ejection passage disposed further outside in the radial direction of the circle than the intake passage and disposed at a position offset toward the other side in the circumferential direction with respect to the intake passage. A washer nozzle is connected to at least one of the first ejection passage and the second ejection passage.

Abstract: A vehicle door structure includes a door body, a window panel, and a washer hose. The door body is attached to a door opening of a vehicle such that the door body can be opened and closed. The window panel is attached to an outer surface of the door body such that a window opening of the door body is covered. The window panel includes an opaque portion that does not allow viewing therethrough at a peripheral region of the window panel. Through the washer hose, washer fluid is supplied. The washer hose is disposed between the outer surface of the door body and the opaque portion.
