    • A process for producing a perfluorobutanesulfonic acid salt (PFBS salt) is provided. By the process, the yield is improved and PFOS salt content is reduced. Electrochemical fluorination is conducted in a reaction solution comprising anhydrous hydrogen fluoride to generate perfluorobutanesulfonyl fluoride, and the fluoride is hydrolyzed to produce a perfluorobutanesulfonic acid salt. The process for producing a perfluorobutanesulfonic acid salt includes: a step in which liquid phase components generated in the electrochemical fluorination cell are withdrawn and a first a perfluorobutanesulfonic acid salt fraction is prepared therefrom; and a step in which gaseous phase components discharged from the electrochemical fluorination cell are collected and a second perfluorobutanesulfonic acid salt fraction is prepared therefrom. The reaction solution in the electrochemical fluorination cell is regulated so as to have a perfluorooctanesulfonyl fluoride content of 500 ppm or lower by withdrawing the liquid phase components from the electrochemical fluorination cell.

    • According to the method for producing bis(fluorosulfonyl)imide of the present invention, first, an unreacted mixed liquid is prepared by mixing a first fluorosulfonic acid with urea in a condition free of a chemical reaction between the first fluorosulfonic acid and urea. Then, the unreacted mixed liquid is dripped into a heated second fluorosulfonic acid or a heated bis(fluorosulfonyl)imide, allowing a chemical reaction between fluorosulfonic acid and urea to proceed. In this method, generation of carbon dioxide gas and heat during the chemical reaction can be controlled.

    • A source controller unit for controlling an x-ray source is provided with a detection signal interface for receiving detection signals from detective pixels of an electronic cassette or an integrated value of the detection signals only, or an interface for receiving a radiation stopping signal only. The source controller unit receives other radiation signals than the radiation stopping signal, such as a radiation admitting signal, through a radiation signal interface. The source controller unit uses the detection signals, the integrated value thereof, or the radiation stopping signal as exposure control signals for stopping radiation from the x-ray source. Since the exposure control signals are received on the specific interface therefor, the source controller unit does not need signal sorting operation nor receive different kinds of signals at the same time, improving the speed of radiation stopping procedure.
    • 用于控制X射线源的源控制器单元设置有用于接收来自电子盒的检测像素的检测信号或仅检测信号的积分值的检测信号接口,或仅用于接收辐射停止信号的接口。 源极控制器单元通过辐射信号接口接收比放射线停止信号(例如辐射允许信号)的其它辐射信号。 源控制器单元使用检测信号,其积分值或辐射停止信号作为用于停止来自x射线源的辐射的曝光控制信号。 由于在特定接口上接收到曝光控制信号,源控制器单元不需要信号分类操作,也不会同时接收不同种类的信号,从而提高了辐射停止过程的速度。

    • In continuous radiography, while a patient stands in front of an imaging support, a total image capture field is determined. The total image capture field is divided into small image capture fields. A map scaling section scales up or down a full spine irradiation area map in accordance with the size of the total image capture field. A map dividing section divides the scaled map into small maps corresponding to the small image capture fields. In each division exposure, a detection pixel selector selects one or more detection pixels belonging to an irradiation area defined by the small map, out of all detection pixels distributed in an imaging surface of an electronic cassette. If an integration value of a detection signal from the selected detection pixel reaches a threshold value, X-ray emission is stopped. Division X-ray images obtained by the division exposures are merged into a single continuous X-ray image.
    • 在连续X线照相术中,当患者站在成像支架前面时,确定总图像捕获场。 总图像捕获字段被分成小的图像捕获字段。 地图缩放部分根据总图像捕捉区域的大小向上或向下放大全脊柱照射区域图。 地图分割部将缩放后的地图分割成与小图像捕捉场对应的小地图。 在每个划分曝光中,检测像素选择器从分布在电子盒的成像表面中的所有检测像素中选择属于由小图定义的照射区域的一个或多个检测像素。 如果来自所选检测像素的检测信号的积分值达到阈值,则X射线发射停止。 通过分割曝光获得的分割X射线图像被合并成单个连续的X射线图像。
