Abstract: A fluid-filled vibration damping device including a first mounting member, a second mounting member including a tubular portion having an end open toward the first mounting member, the first and second mounting members being spaced from, and opposed to, each other, an elastic rubber body which elastically connects the first and second mounting members to each other, and which fluid-tightly closes the open end of the tubular portion of the second mounting member and cooperates with the tubular portion to define a fluid chamber filled with a non-compressible fluid, and a working member which is supported by the first mounting member such that the working member extends, in the fluid chamber, in a direction substantially perpendicular to a central axis of the tubular portion of the second mounting member, and thereby divides the fluid chamber into two divided chambers which are located on opposite sides of the working member, respectively, and which are communicated with each other via a fluid-flow restricting p

Abstract: An optical fiber array includes an upper substrate and a lower substrate in which V-shaped grooves are formed. Optical fibers are inserted and arranged in the V-shaped grooves and are solidified using an adhesive. The upper substrate comprises a fiber presser substrate for pressing the optical fibers in the V-shaped grooves and a covered fiber housing substrate in which covered optical fibers are housed. The lower substrate comprises a V-shaped groove section having V-shaped grooves in which the optical fibers are aligned and arranged, a covered optical fiber support section for supporting the covered optical fibers, and a V-shaped groove step section located between the V-shaped groove section and the covered optical fiber support section. The top surface and/or sides of a non-covered optical-fiber section are opened between the V-shaped groove section or the V-shaped groove step section and the coverage-removed end of the covered optical fibers.
