An inspection sorting apparatus includes an X-ray tube with an anode electrode and a cathode electrode, a tank housing the X-ray tube and having insulation oil contained therein, and the anode electrode and the cathode electrode are supplied with a predetermined voltage to generate X-ray. An inspection sorting apparatus has an abnormal discharge determination unit, an LCD display, and a notification control unit. The abnormal discharge determination unit individually detects a first abnormal discharge which is an abnormal discharge inside the X-ray tube, and a second abnormal discharge which is an abnormal discharge inside the tank outside the X-ray tube. The LCD display outputs notification information prompting an administrator to replace the X-ray tube or the tank. The notification control unit causes the LCD display to output the notification information in accordance with a detection result from the abnormal discharge determining unit.

X-ray generator and X-ray inspection apparatus

Provided is an X-ray generation device including an X-ray tube and a high-voltage generation unit arranged inside a housing and also having insulating oil filled in the housing, which uses no lead and is small in size, thereby achieving a reduction in manufacturing cost, and which also has high cooling performance. An X-ray generation deviceincludes an X-ray tubeand a high-voltage generation unitinside a housingand also has insulating oilfilled in the housing, the X-ray tubebeing configured to generate an X ray, the X-ray generation devicecharacterized in that the X-ray tubeis arranged inside an X-ray tube holder, a material of the X-ray tube holdercontains at least bismuth oxide and a resin, and the X-ray tube holderincludes an opening and a plurality of slits, the opening being provided in a portion corresponding to an X-ray irradiation windowthrough which the X-ray tubeapplies the X ray, the slitsallowing the insulating oilto circulate between an inside and an outside of the X-ray tube holder

X-ray generation device

Provided is an X-ray irradiator which reduces the occurrence of discharge resulting from the difference in electric potential in the X-ray irradiator, and which concurrently achieves reduction in size and weight. In an X-ray irradiator (), an X-ray tube () and a high-voltage generator () are installed inside a casing (), and an insulation oil () is filled in the casing (). The high-voltage generator () is configured by arranging and electrically connecting together multiple ring-shaped voltage amplifying units (). An anode () and a cathode () of the X-ray tube () are fitted in and thus installed in hollow portions of the voltage amplifying units ().
