摘要： PURPOSE:To lessen and decrease power and amount of heat required for operation by eliminating the processes of liquefaction, compression and heating-up in recovering solvent. CONSTITUTION:Super critical extraction solvent or super critical liquefied carbon solvent or super critical liquefied carbon dioxide gas is contacted in the extracting tank 6 with the substance to be extracted in the shape of fog or drop supplied from the supplying device 11 of the substance to be extracted, and the required content is solved and extracted out of the said substance. The liquefied carbon dioxide which solved the substance to be extracted is led from the extracting tank 6 into the separating tank 8. In the said separating tank 8, the super critical carbon dioxide which solved the required content is separated through the separating membrane to the upper chamber side. Also in the lower chamber, separated from the super critical carbon dioxide, the required content is extracted and separated, stored in the extracting tank 9 and extracted. The super critical carbon dioxide separated into the upper chamber of separating tank 8 is passed through the pressure control valve 10, supplied into the filter 2 and recirculated to be utilized as a solvent.

摘要： PURPOSE:To readily separate bile acid of high purity even in the case where a raw material with a low bile acid content is used, by separating the bile acid from an alcohol obtained by extracting an esterification solution of a raw material containing the bile acid with a supercritical gas or liquefied gas. CONSTITUTION:A raw material containing bile acid, e.g. fish oil, is esterified with a lower alcohol under conditions to form an excess alcohol, and the resultant esterification solution 10 is then introduced into an extraction tank 1 and brought into contact with, for example, a supercritical gaseous carbon dioxide 20 to dissolve preferentially a fatty acid ester, alcohol and bile acid ester in the supercritical gaseous carbon dioxide. The esterification solution 10 and supercritical gaseous carbon dioxide are separated by specific gravity difference to introduce the supercritical gaseous carbon dioxide 20' into the first-stage separation tank 2 and lower the density of the critical gaseous carbon dioxide. Thus, the fatty acid ester 12 is preferantially separated. The alcohol 11 and free bile acid ester 14 are then separated in the secon-stage separation tank 3, and the resultant bile acid ester is separated by crystallization.

摘要： PURPOSE:To enhance measuring accuracy by permitting no reception of the auxiliary beam path of irradiation beam due to a concaved shape by a sensor, by a method wherein an angle changing mechanism is formed of a biaxial constitution consisting of the rotary axis in a plane, which is right-angled to the irradiation optical axis of a beam spot position detecting sensor and contains the irradiation optical axis and a beam receiving axis, and the rotary axis passing the intersecting point of the rotary axis and the irradiation optical axis and right-angled to said two axes. CONSTITUTION:An angle changing mechanism 2 is formed of a biaxial constitution consisting of a rotary axis Z right-angled to the irradiation optical axis 8 of a beam spot detection sensor 1 and containing the irradiation optical axis 8 and a beam receiving axis 9, and a rotary axis Y passing the intersecting point P of the rotary axis Z and the irradiation optical axis 8 and right-angled to said two axes. This mechanism 2 is combined with a three- dimensional drive mechanism 3 to constitute a non-contact measuring system and an object 5 to be measured is placed on a moving table 4 moving in an X-direction. The beam from the beam source 3 is allowed to irradiate the P-point on the object 5 and the irregular reflected beam from the P-point is received by the beam receiving lens 10 arranged on a beam receiving optical axis 9 forming an angle gamma with respect to the irradiation optical axis 8 and detected by a beam receiver 11 to prevent the auxiliary beam path of irradiation beam due to a concave shape from being received by the sensor 1.

摘要： PURPOSE: To extract and separate an objective substance with high efficiency, by enabling the change-over of extraction tanks and continuously extracting a substance to be extracted while independently controlling the pressures and temps. in the extraction tanks and a separation tank.
CONSTITUTION: After an objective substance was introduced into an extraction tank 27A, the fluid of a fluid source 1 is allowed to gradually fill the whole of the system through pipings 2, 3, 6, 14. Next, a liquefier 53 is operated to liquefy the fluid. Subsequently, the substance to be extracted, which was extracted in the extraction tank 27A, is mixed with an super-critical fluid to be sent to a separation tank 34 where the fluid is separated from the extracted substance to be sent to a gassification tank 48. The fluid issued from the gassification tank 48 is passed through the liquefier 53 to be perfectly liquefied and sent to a recirculation pump 10 to be recycled and utilized. Further, the extraction time of the objective substance in the extraction tank or the extraction amount of the objective substance in the separation tank is set as a change- over condition and the change-over of extraction tanks 27A, 27B is performed by a change-over control mechanism consisting of automatic valves 19A, 19B, 28A, 28B.
