摘要： The first process for producing an optical fiber coupler includes a first step wherein at least one of the optical fibers to be used is stripped of the coating, a second step in which the bare portion of that optical fiber is heated for a predetermined time to diffuse the dopants, a third step wherein the other optical fibers which have not been heat-treated are stripped of their coating, a fourth step in which the bare portions of all the optical fibers are heated as they are brought into intimate contact, thereby forming a unitary portion, and a fifth step wherein the unitary portion is drawn via heating to form the coupling portion of an optical fiber coupler. The second process for producing an optical fiber coupler includes stripping the coating from at least one optical fiber, fixing the fiber so as to impart an axial stress thereto and then heating the bare portion of the stripped optical fiber thereby thinning the diameter of the heated portion, and then proceeding in the same manner as described with respect to the third through fifth steps of the first embodiment of the present invention. The processes according to the present invention enable a wide-band optical fiber coupler to be easily produced without using optical fibers of different structures but using optical fibers of identical structures.

摘要： An air-outlet mode selecting device includes first and second rotary doors. Each of the first and second rotary doors has rotary shafts separated from each other in an axial direction of the rotary shafts, an outer peripheral door surface that is provided at a position separated radial outward from the center line of the rotary shafts and is turned with the rotary shafts, and left and right side plates for connecting both ends in the axial direction of the outer peripheral surface and the rotary shafts. One of the first and second rotary doors opens and closes a specified opening among three openings and other rotary door opens and closes the remaining two openings among the three openings. Accordingly, door operation force and air flow resistance can be effectively reduced, and the size of the air-outlet mode selecting device can be effectively reduced.
