Abstract: A fire extinguishing system of an aircraft including a nozzle device that is provided on an installation member forming a compartment of the aircraft, wherein the nozzle device includes: a nozzle that is passed into an insertion hole formed in a nozzle installation section provided on the installation member, and discharges a fire extinguishing agent supplied from a supply source into the aircraft compartment; and a lid member that closes a gap between the nozzle and the nozzle installation section.

Abstract: A fire extinguishing system of an aircraft, including: a fire extinguishing nozzle device that is provided on an installation member forming a compartment of the aircraft; and a fire extinguishing pipe that is provided on a support structure supporting the installation member from a back side, and supplies a fire extinguishing agent to the fire extinguishing nozzle device. The fire extinguishing pipe is restrained to the support structure at a plurality of restraint positions. A holding device that holds the fire extinguishing pipe and is provided on the support structure is used at at least one of the plurality of restraint positions. The holding device includes a holding section that holds an outer periphery of the fire extinguishing pipe, and a disengaging section that enables disengagement of the fire extinguishing pipe.

Abstract: To provide fibers for artificial hair prepared under a low nozzle pressure with little gumming, and a fiber bundle for artificial hair having a soft touch close to human hair, while maintaining uniform curling. A fiber bundle for artificial hair comprising fibers (A) having a flexural rigidity of (1.2 to 3.5)×10?2 N·cm2 as determined by the KES method and fibers (B) having a flexural rigidity of (0.5 to 1.0)×10?2 N·cm2 as determined by the KES method, wherein both of the fibers (A) and the fibers (B) are made of vinyl chloride fibers. The fiber bundle for artificial hair, wherein the content of the fibers (A) is from 30 to 90 mass %, the sectional shape of the fibers (A) is at least one selected from the group consisting of Y-, U- and C-shapes, and the sectional shape of the fibers (B) is a spectacled sectional shape.
