An X-ray fluoroscopic system which is capable of highly accurately performing tilting tracking or rotational tracking by a simple operation in an observation work without inputting a distance from the surface of a table and an observed point of an object of fluoroscopy and without performing a calibration operation for obtaining the distance in advance. The X-ray fluoroscopic system having a tracking function of obtaining a moving amount of the table, which is necessary for performing tilting or rotational tracking, and moving the table, based on an arithmetic operation using a distance h obtained by totalizing a distance d from the surface of the table to an observed point V, and a distance z from the surface of the table to an X-ray focal point, a defined value or arbitrary input value is used as an initial value of the distance h, and a shift amount of the observed point V occurred from tracking is used to update the distance h by specifying the observed point V on a screen after tracking, thereby tilt (rotation) tracking accuracy is gradually improved.

X-ray fluoroscopic system

The object of the invention is to provide a unit for vaporizing liquid materials which can adjust not only a mixing rate but also a concentration of the mixed liquid easily and accurately and which can effectively vaporize a large amount of the liquid material. A unit for vaporizing liquid materials in accordance with the invention is for mixing a plurality of liquid materials and comprises a plurality of containers each of which contains a different liquid material which is made by dissolving a material into a solvent, a container exclusive for solvent which contains the same or the same kind of solvent used for the liquid materials, a liquid conveying means which conveys the liquid materials from the containers and the solvent from the container exclusive for solvent, and a vaporizing means which sprays the liquid materials and the solvent conveyed by the liquid conveying means and vaporizes the sprayed liquid materials and the sprayed solvent.
