Filed: 2009-12-11
Abstract: 本発明は、野生型ターマミル様アルファ‐アミラーゼ、例えば、バシルス（Ｂａｃｉｌｌｕｓ）アミラーゼなどと全部において又は一部において保存された３Ｄ構造を共有するハイブリッドアルファ‐アミラーゼを提供する。ハイブリッドにおいて、ターマミル様アルファ‐アミラーゼのＮ末端部分が、古細菌アミラーゼ由来の配列で置換される。二つのアミラーゼ間の配列類似性は、６０％未満でよい。ハイブリッドにおける野生型３Ｄ構造を保存することは、酵素的に活性のあるアミラーゼを得ることを容易にする。ある実施態様においては、一つ又は両方のアミラーゼ配列はＢドメイン残基に寄与し、特に有用な特性をもたらす。例えば、ターマミル様アルファ‐アミラーゼのＢドメインにおけるＣａ ２＋ 結合部位をＣａ ２＋ を結合しない古細菌アルファ‐アミラーゼのＢドメイン配列で置換することによりＣａ ２＋ 非存在下完全に活性であるハイブリッドを生成できる。 【選択図】図２

Title: 格子を用いたシングルステップの低線量ｘ線位相コントラストイメージング
IPC: A61B6/00
Filed: 2010-02-03
Abstract: 従来、位相情報を格子干渉計で検出された他の寄与から区別するために、位相ステッピング法が考えられてきた。これは複数のＸ線投影像の取得を伴う。これに対して、本発明は、位相ステッピングを要さずに位相コントラスト信号を抽出する、格子干渉計に基づいた革新的な高感度Ｘ線トモグラフィ位相コントラストイメージング方法を提供する。既存の位相ステッピング法と比べて、「逆投影」と呼ばれるこの新しい方法の主な利点は、画質を劣化させることなく、投与線量が著しく低減されることである。この新しい技術は、生物検体のイメージングと生体内研究に不可欠であり、将来の高速かつ低線量の位相コントラストイメージング法の前提条件をなす。

Filed: 2012-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of properly adjusting shooting intensity with respect to a manipulated variable of an operating handle.SOLUTION: An MPU 201 in a main control device 110 increases a shooting application voltage Eα to a limit value of limit value memory 202d by processing in step S1811 and outputs the increased voltage to a shooting control device 400, when detecting that the manipulated variable of turning of the operating handle 51 exceeds an angle of 105 degrees by processing in step S1807.
