Abstract: A dialysis apparatus has a dialysate circuit 4 which is cleaned after dialysis by both opening/closing valves V101 and V102 being closed after a dialysate in the dialysate circuit 4 is replaced with a cleaning liquid. The opening/closing valve V12 is opened, and the cleaning liquid is circulated by pumps P1 and P4 while being heated by a heater H1, to clean the inside of the dialysate circuit 4. A deaeration tank 31 is provided downstream of the pump P1. Air bubbles generated from the cleaning liquid serving as hot water are deaerated by the deaeration tank 31 and are then discharged into a gas storage tank 48 via a deaeration passage 32. The pumps P1 and P4 can be reliably prevented from being unable to operate with the air bubbles generated from the cleaning liquid.

Abstract: There is provided a method of charging a hollow valve with metallic sodium easily and swiftly without being oxidized over the surface of the metallic sodium and an apparatus therefor. The metallic sodium is fed into a cavity of the hollow valve in which a valve stem has a smaller diameter. A workpiece, a semi-finished product for a hollow poppet valve, is disposed at a working position where an opening is directed upward. A cavity of the workpiece is open at a free end of the valve stem. A nozzle is inserted into the opening. An inert gas is jetted from the nozzle and is fed into the cavity. Then, the nozzle is moved up, and a holder that holds the rod-like metallic sodium 10 is disposed between the workpiece and the nozzle. While the inert gas is jetted from the nozzle, the metallic sodium is pressed into the cavity of the workpiece.
