Abstract
Description
本開示における発明の概要は、読み手が技術的開示の性質を迅速に確認できるように提供される。これは、特許請求の範囲の意味または範囲を説明または限定するために用いられるものではないという理解の下、提示される。更に、上記の発明を実施するための形態において、本開示を合理的にするために様々な特徴が様々な実施形態にまとめてグループ分けされていることが分かる。この開示方法は、特許請求対象である実施形態が各請求項に明記されたもの以外の特徴を必要とするという意図を反映するものとして解釈すべきではない。むしろ、以下の特許請求の範囲が示すように、発明の主題事項は、開示された単一の実施形態の全ての特徴よりも少ない特徴にある。したがって、以下の特許請求の範囲は発明を実施するための形態に組み込まれ、各請求項は、個別に特許請求される主題事項として独自的なものである。
