Abstract: An X-ray detector is connected to a large number of detector modules connected in series. The X-ray detector detects X-ray image data for each detection module, each module synchronously reading X-ray image data detected by itself based on an internal clock ?, each module transferring the read X-ray image data one after another. Each of the detection modules receives the transferred X-ray image data, and resynchronizes the received X-ray image data by using the internal clock, and transfers the same together with the detected X-ray image data. This enables arranging the detection module at an arbitrary position without a change in the method of transferring data for each measurement or without a load on a control device.

Abstract: To provide an X-ray detector facilitating the installing and replacement work of a module while reducing the possibility of breakage. An X-ray detector 50 detecting X-ray image data for each detection module includes: a detection module 7 provided with a protruding frame on aback side of a detection device detecting X-rays; and a guide frame 12 fitting into the protruding frame and removably supporting the detection device, wherein the guide frame 12 fixes the position of the detection device relative to the guide frame 12 by fitting. Therefore, fitting the protruding frame 8 into the guide frame 12 enables precise and easy installation/removal of the detection module. That is a detection module can be newly installed onto the guide frame without interfering each other with adjacent detection modules already installed while minimizing a space therebetween.

According to the invention, the FAD-GDH can be highly expressed by altering DNA sequence coding for a signal peptide of FAD-GDH gene isolated from Aspergillus oryzae. FAD-GDH can be stably produced by adjusting pH of 7.1 to 7.3 during culture production.

Abstract: An X-ray analysis apparatus has information about a relationship between selection of a measurement type and a replacement work of optical parts and shows, on a screen of a display, graphical information about optical parts which should be changed, to make it easy for an operator to perform a preliminary work before measurement. When the operator selects one desired measurement type among a plurality of measurement types in a selection window, there is displayed on the display, depending on the selected measurement type, graphical information about necessary optical parts which should be newly installed and/or installed optical parts which should be removed. The operator looks at the operating instructions and then performs the replacement work. The graphical information may be: graphical indication of the installation locations of the optical parts; different pictorial expressions about the installation and the removal works; and graphical indication of the identification marks of the optical parts.
