Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は水産業等に使用する注気用等の多孔性パイプ
に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a porous pipe for insufflation used in the fishing industry and the like.
本件考案者は、表面に突条を有するパイプとして特願
昭56−205780号を提案した。The inventor of the present invention has proposed Japanese Patent Application No. 56-205780 as a pipe having a ridge on its surface.
しかしこれでは通気量が少なく、農業の灌漑用には差
支えないが、水産業の注気には不充分である。However, although this has a small air flow and can be used for agricultural irrigation, it is not sufficient for the fishing industry to pay attention.
