ナノシステム研究部門のロゴは、「蜂 : Megaphragma caribea 」と「虫メガネ ( 電子顕微鏡 )」をデザインしています。
この蜂は飛行能力をもつ地上最小の昆虫 ( 寄生バチ ) です。翅 ( はね ) の色分けは、当研究部門の4つの研究の柱に対応
しています。青が情報通信・エレクトロニクス対応(IT システム)、緑が環境・エネルギー対応(グリーンシステム)、
ピンクがライフサイエンス対応(ソフトシステム)、そして黄が、上記3つを結び付けるテクノロジーブリッジです。
The logo of our research institute symbolizes a bee and a magnifier (electron microscope). The bee is called
Megaphragma caribea , which is known as the smallest animal in the world that can fly high by itself. The
four colors of its wings correspond to the four main pillars of our research activity: blue represents
information technology and electronics (IT System), green the environment and energy (Green System), pink
life science (Soft System), and yellow the Technology Bridge that connects the above three categories.
