  • Publication number: 20210041631
    Abstract: A fiber module (1B) according to the present disclosure includes an input-side optical fiber (11), an output-side optical fiber (12), a ferrule (20) in which the input-side optical fiber and the output-side optical fiber are insertable in both ends and a groove (32) is formed in a direction orthogonal to a longitudinal direction (D1) in the middle of the longitudinal direction, a dielectric multilayer film filter (30) inserted in the groove, and an input-side GI fiber (15) and an output-side GI fiber (16) joined by fusion to respective terminal portions of the input-side optical fiber and the output-side optical fiber. The dielectric multilayer film filter is interposed between an end surface (15f) of the input-side GI fiber and an end surface (16f) of the output-side GI fiber in the longitudinal direction.

  • Publication number: 20200181433
    Abstract: There is provided a rubber composition for additive manufacturing that allows a rubber shaped article to be favorably produced using an additive manufacturing apparatus, and allows the obtained rubber shaped article to achieve both high mechanical strength and excellent elongation. The rubber composition for additive manufacturing comprises a liquid rubber, an amine-based urethane acrylate oligomer, and a monomer, wherein a total content of the amine-based urethane acrylate oligomer and the monomer is 30 parts by mass or more, per 100 parts by mass of the liquid rubber.
