Abstract: An air supply and exhaust system comprising a pneumatic tool, an air supply source, an exhaust apparatus, and at least one double-pipeline air hose. The exhaust apparatus includes a filter through which exhaust from the pneumatic tool passes and is provided apart from the pneumatic tool. The double-pipeline air hose includes two pipelines and connects the pneumatic tool and the air supply source, wherein one of the pipeline is for air supply to the pneumatic tool and the other of pipeline is for exhaust from the pneumatic tool.

Abstract: A transfer member with a pattern of metallic luster is so constructed that a release layer is formed on the whole surface of a release sheet, a metal thin film layer is formed on the release layer, and a pattern-like adhesive layer including thermosetting resin and 5-70 parts by weight of loading pigment is formed thereon. As required, the metal thin film layer is partially formed to partially form a color adhesive layer on the release layer. The metal thin film layer is formed on the whole surface of the release layer formed on the whole surface of the release sheet, then, the pattern-like adhesive layer is formed on the metal thin film layer, thereafter a part of the metal thin film layer which is not covered with the adhesive layer is dissolved and removed therefrom by alkaline or acidic aqueous solution, and then the pattern-like color adhesive layer is formed thereon to manufacture a transfer member.
