摘要:
A fine-bubble generator is capable of supplying a fluid mixed with a large quantity of fine bubbles into a fluid without causing an unnecessary liquid flow and turbulent flow in the objective fluid. The fine-bubble generator is constructed by arranging two fine-bubble generating sections in a rectangular parallelepiped casing with spouts of the fine-bubble generating sections facing each other. The fine-bubble generating sections have fluid rotating chambers each composed of a circumferential wall provided around an imaginary center line and partition walls arranged at both ends of the circumferential wall, liquid introducing passages provided so as to communicate with the fluid rotating chambers in order to introduce a liquid along a direction that forms a position twisted relative to the imaginary center line, gas introducing passages opened in the partition wall of each of the fluid rotating chambers in order to introduce a gas into each of the fluid rotating chambers, and spouts opened in the partition walls.

A fine-bubble generator capable of supplying a fluid mixed with a large quantity of fine bubbles into a fluid without causing an unnecessary liquid flow and turbulent flow in the objective fluid. A fine-bubble generator (11) is constructed by arranging two fine-bubble generating sections (12, 13) in a rectangular parallelepiped casing (11a) with spouts (28a, 28b) of the fine-bubble generating sections (12, 13) to face each other. The fine-bubble generating sections (12, 13) have fluid rotating chambers (25) each composed of a circumferential wall (25d) provided around an imaginary center line (25c) and partition walls (25a, 25b) arranged at both ends of the circumferential wall (25d), liquid introducing passages (18a, 18b) provided so as to communicate with the fluid rotating chambers (25) in order to introduce a liquid along a direction that forms a position twisted relative to the imaginary center line (25c), gas introducing passages (14a, 14b) opened in the partition wall (25a) of each of the fluid rotating chambers (25) in order to introduce a gas into each of the fluid rotating chambers (25), and the spouts (28a, 28b) opened in the partition walls (25b).

摘要:
A medical ultrasonic generator having an ultrasonic radiator wound with coils connected to a high-frequency oscillator, when the radiator is provided with a sintered element consisting essentially of Ni--Zn having a thickness of 8 to 20 mm. The ferrite element can effectively apply the ultrasonic oscillation to a human body to improve the effect of medical treatment. Further, the medical ultrasonic generator is superior in terms of workability as a medical treatment because of its ability to effectively apply the ultrasonic oscillation to the affected part even through the clothing worn by a patient.
