  • Publication number: 20130045934
    Abstract: The present invention provides an extraction method that either does not use emulsifiers, organic solvents, and the like or can reduce the amount used of emulsifiers, organic solvents, and the like. In addition, the extraction method of present invention can also efficiently extract various components from various materials to be extracted, and can highly maintain potency and the like of the extracted components, in particular if the components are active agents. Furthermore, the extraction method of present invention has excellent safety. The extraction method of present invention is achieved by bringing materials to be extracted into contact with liquid containing ultra fine bubbles for extraction treatment. The ultra fine bubbles utilized during the extraction process preferably have a mode diameter of 500 nm or smaller and a concentration of 1,000,000 or more per 1 ml of liquid.

  • Patent number: 4566453
    Abstract: A vascular anastomosis apparatus using a carbon dioxide laser is proposed. The vascular anastomosis apparatus satisfies three conditions: a long focal distance of not less than 10 cm which is suitable for surgical operations under microscopic observation; a beam spot diameter of 0.1 to 0.3 mm when a laser beam is converged; and a stable, small beam output of not more than 100 mW. A visible guide beam having the same focusing point as that of the carbon dioxide laser beam is used in the vascular anastomosis apparatus.

  • Patent number: 4446239
    Abstract: A technique for measuring the degree of an antigen-antibody reaction by preparing a suspension of insoluble microscopic carrier particles of at least one type carrying an antigen, an antibody or a hapten, forming an agglutination promoting or inhibiting reaction system among the insoluble carrier particles based on an antigen-antibody reaction using the suspension and one or more antigen, antibody or hapten, irradiating the solution of the reaction system with laser light and detecting the light scattered from the reaction system at one or more specific angles, detecting a signal indicative of one or more specific frequency bands from the resulting scatter spectrum, and thenceforth calculating the quantity of antigen, antibody or hapten in a specimen on the basis of the detected signal. The intensity spectrum output of filter 11 for frequency band selection is in the form of a square root and is converted into the original intensity spectrum by means of a squaring circuit 12.

  • Patent number: 4429583
    Abstract: An apparatus for taking up and discharging liquid has at least one piston cylinder which responds to a command by taking up or discharging liquid, the arrangement being such that the number of liquid uptake operations is preset, with the piston cylinder being instructed to perform the discharge operation when the number of uptake operations actually performed is detected to exceed said preset number. A plurality of different liquid specimens can be mixed, and the mixture diluted when so desired, through a simple operation which assures great accuracy.
