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 (1), an X-ray tube (11) and a high-voltage generator (2) are installed inside a casing (18), and an insulation oil (13) is filled in the casing (18). The high-voltage generator (2) is configured by arranging and electrically connecting together multiple ring-shaped voltage amplifying units (21). An anode (14) and a cathode (15) of the X-ray tube (11) are fitted in and thus installed in hollow portions of the voltage amplifying units (21).
摘要:
A flow proportioning assembly for dividing a portion of a fluid flow such as gas for presentation to a sensor includes a holder member having a central opening and forming an exterior peripheral passageway when inserted within a conduit of a flow meter housing. A resistor member can be adjustably mounted in the central opening downstream of a holder member aperture to encourage a laminar flow pattern and a large entrance port and a large exit port can communicate with a passageway that is operatively connected with a sensor. The exit port is downstream of the resistor member. Flexible fastener members can engage the resistor member and the holder member for ease of mounting. The resistor member can also comprise a helical arrangement of small fluid passageways to encourage laminar flow.
