The object is to provide an aircraft component positioning device, an aircraft assembly system, and an aircraft assembly method with which it is possible to precisely dispose components on a planar member of an aircraft without using a positioning jig. A positioning device () includes a detection unit () that detects positions of a plurality of first components installed on a planar member of an aircraft, a virtual position creation unit () that creates a virtual position between the plurality of first components on the basis of the positions of the plurality of first components that are detected, and a position determination unit () that, on the basis of the virtual position that is created, determines an installation position of a second component, different from the plurality of first components, that is installed on the planar member.

Aircraft component positioning device, and aircraft assembly system

A vinyl chloride resin composition having an improved impact resistance with a good transparency that the vinyl chloride resin itself possesses originally; which comprises (A) a graft copolymer prepared by (i) adding a water-soluble electrolyte to a butadiene polymer (a) (ii) adding a monomer mixture (b) containing mainly an aromatic vinyl monomer to polymerize, (iii) adding a monomer mixture (c) containing mainly an alkyl methacrylate to polymerize and (iv), when desired, adding a monomer mixture (d) containing mainly an aromatic vinyl monomer.

Vinyl chloride resin composition

A vinyl chloride resin composition having an improved impact resistance with a good transparency which includes (A) a graft copolymer reinforcing agent prepared by emulsion-polmerizing 15 to 35 parts by weight of a monomer mixture in the presence of 85 to 65 parts by weight of a butadiene homopolymer or copolymer having a butadiene content as high as 82% by weight or more, said monomer mixture containing of 50 to 95% by weight of an aromatic vinyl monomer such as styrene, 0.1 to 40% by weight of a vinyl cyanide monomer such as acrylonitrile and 0 to 40% by weight of other vinyl monomer copolymerizable therewith, and (B) a vinyl chloride resin. The butadiene homo- or copolymer may be treated prior to the emulsion polymerization, in order to prevent the produced graft copolymer particles from coagulating into a massive material, by reacting a small amount of a crosslinking monomer and optionally an alkyl acrylate or methacrylate in the presence of the butadiene homo- or copolymer in the form of an aqueous latex.
