    • An X-ray tube 1 is heated under an X-ray scan condition (tube voltage V, tube current I, exposure time width t) and thus a focal point is shifted. Artifact occurs in a reconstructed image due to the focal point shift. The present invention has an object to enable correction of the focal point shift caused by heating the tube. The applicant and inventor of this application has confirmed that the focal point shift amount of the tube 1 varies in accordance with whether it is in a heating direction or cooling direction when viewed from a past sequence. Therefore, the sequence record and the focal point shift amount based on the heating and cooling directions are stored as data in a storage device 13. A just near past sequence record when viewed from now is stored in a storage unit 16, and the tube temperature is detected by a tube temperature detector 15. On the basis of this temperature and the data in the storage unit 16, heating or cooling and the present accumulated heat capacity are determined in a determining unit 17, and the storage device 13 is accessed to determine a focal point shift amount. The position of the tube is corrected on the basis of this shift amount.
    • 在X射线扫描条件(管电压V,管电流I,曝光时间宽度t)下加热X射线管1,从而使焦点偏移。 由于焦点偏移,人造物发生在重建图像中。 本发明的目的是能够校正由加热管导致的焦点偏移。 本申请人的申请人和发明人已经确认,根据从过去的顺序观察,管1的焦点偏移量是否根据加热方向或冷却方向而变化。 因此,基于加热和冷却方向的顺序记录和焦点偏移量作为数据存储在存储装置13中。从现在观看的刚刚过去的顺序记录被存储在存储单元16中,并且管温度 由管温度检测器15检测。基于该温度和存储单元16中的数据,在确定单元17中确定加热或冷却和当前累积热容量,并且存储设备13被访问以确定 焦点偏移量。 基于该偏移量来校正管的位置。

    • A fill-up control valve structure includes a casing attached to a fuel tank, a float provided in a space defined in the casing so as to cause an up-and-down movement, a valve body provided at an upper portion of the float, a ventilation passage communicating with a downstream side of the valve body, and at least one first ventilation hole opened at a lower part of the casing to connect the inner space of the casing and the fuel tank to introduce fuel from the fuel tank into the space. Furthermore, at least one second ventilation hole is provided at an upper part of the casing to connect the inner space of the casing and the fuel tank. The hole size of second ventilation hole is smaller than that of the first ventilation hole.
