摘要： A rotary anode X-ray tube accommodated in a housing together with oil has a journal box fixed and inwardly extending inside the tube, an anode target fixed to a rotor supported by the journal box and a cathode member opposing the anode target and fixed at an end portion inside the tube opposing the journal box. The fixing portion between the rotary anode X-ray tube and the journal box is supported by a resilient support member on the housing and vibration damping means is disposed on the support member. The vibration damping means includes a moving member fixed at its center and a fixed member fixed to the housing so as to encompass the moving member with a predetermined gap, and oil is fully charged in the gap. Vibration of the rotation system is transmitted to the moving member and the operation of this member damps the vibration by means of the squeeze action of the oil.

摘要： A rotary shaft of a hydraulic machine has a collar projecting radially outwardly therefrom. The rotary shaft and the collar are encased by a casing which carries a seal ring to be pressed against an axial end surface of the collar to form a fluid-tight seal therebetween. The axial end surface of the collar slidingly contacting with the seal ring is provided with a plurality of radial grooves extending from the central portion of the collar to the outer peripheral edge thereof. As the rotary shaft rotates at a high speed, a centrifugal force is generated to separate sand and soil particles from the water within the radial grooves.
