Disclosed is a rotor/stator type homogenizer which allows the gap between the rotor and the stator to be set to a very small dimension and which does not involve generation of abrasion particles or the like even if the rotor is rotated at high speed, making it possible to efficiently homogenize a plurality of liquids having no mutual compatibility. The inner peripheral surface of the stator and the outer peripheral surface of the rotor are opposed to each other through a predetermined gap and a portion of the solutions is introduced into the gap to form a hydrodynamic bearing, thereby supporting rotation of the rotor with respect to the stator.

Rotor/stator type homogenizer

Disclosed are a dynamic pressure seal device and a rotary joint device using the same which are applicable to a rotary body to be rotated at high speed and which are capable of effecting delivery of a target fluid between a rotary side member and a stationary side member without involving any leakage for a long period of time even when used for delivery of a high pressure fluid. The dynamic pressure seal device includes: a stationary side member mounted to a stationary portion and a rotary side member mounted to a rotary body, wherein the stationary side member and the rotary side member are opposed to each other through the intermediation of a predetermined bearing gap, a lubricant fluid being introduced into the gap to form a dynamic pressure bearing, the gap between the stationary portion and the rotary body being hermetically sealed by this dynamic pressure bearing.
