摘要： PURPOSE:To industrially and advantageously obtain a high-purity steroid, e.g. cholesterol, etc., from a fish oil raw material, etc., by adding an alkali to saponify the fat or oil raw material, bringing the saponified fat or oil into contact with a suprcritical gas, extracting and separating the steroid in the fat or oil raw material. CONSTITUTION:A fat or oil raw material 2, e.g. fish oil, etc., is fed from a feed pipe (2a) to a saponification tank 1 and an adequate amount of an alkali is added from an alkali tank 5 to saponify the raw material 2 by feeding steam from a steam pipe (1a) and imparting moderate heating and stirring with a stirring device 4. Water, etc., is then added from a solvent tank 6 to slurry the saponified material. The slurried material is fed to an extraction tank 12. On the other hand, gaseous carbon dioxide from a gaseous carbon dioxide feeder 8 is liquefied in a liquefier 9, converted into a supercritical state by a high-pressure pump 10 and heat exchanger 11, fed to the extraction tank 12 and brought into contact with the saponified fat or oil raw material to extract steroid. The supercritical gaseous carbon dioxide dissolving the extract is then fed to a separation tank 13 to separate an extract 15 and afford the aimed compound.

摘要： PURPOSE:To easily inject a modifier into a high-pressure system and to continuously introduce a solid raw material into an extraction vessel by mixing the raw material and the modifier and injecting the mixture into the extraction vessel. CONSTITUTION:When a modifier is added into a supercritical gas and a material to be extracted is decomposed, a raw material contg. the material to be extracted and a solvent as the modifier are mixed in a mixing vessel 10, the mixture is forced by a pump 20 into an extraction vessel 16 which is filled with an extractant through an injection pipeline 18 and the material to be extracted in the raw material is eluted into the extractant. Then the material to be extracted and the solvent are separated from the extractant and recovered in a separation vessel 32 and a vessel 42 for recovering the solvent as the modifier. Consequently, the solvent as the modifier can be easily injected into a high-pressure system and the solid raw material can be continuously introduced into the extraction vessel 10.

摘要： PURPOSE:To easily perform not only the recovery of a stock material residue and an extracted substance but also the washing of an inner container and to prevent the clogging of the pipings attached to an extraction tank and a separation tank, by respectively storing the stock material residue and the extracted substance in the inner containers provided in both tanks in a detachable manner. CONSTITUTION:Carbon dioxide is introduced into the stock material in the inner container 11 of an extraction tank 11 in a state of a supercritical gaseous fluid to be contacted with the stock material and the component to be extracted in the stock material is dissolved in and extracted with the gas while the residue of the stock material is left in the inner container 11. Thereafter, the supercritical gas is introduced into the inner container 21 of a separation tank 2 and the density of the gas is reduced to separate the extracted substance which is, in turn, stored in the inner container 21. The supercritical carbon dioxide separated in the separation tank 2 is introduced into the inner container 31 of an evaporation tank 3 to be separated into carbon dioxide and the extracted substance. After extraction operation was completed, operation is stopped and the inner containers 11, 21, 31 are taken out of the system and, after the stock material residue and the extracted substance were recovered, said inner containers are washed.

摘要： PURPOSE:An extraction raw material such as animal or vegetable substance is made to contact with a supercritical gas together with an extraction assistant consisting of an alcohol or an organic solvent to effect the extraction of the extractable substance in the supercritical gas and the extractable substance is separated by varying the pressure and temperature of the supercritical gas. CONSTITUTION:The extraction raw material is mixed with the extraction assistant (e.g. alcohol, organic solvent, etc.) in the stirring tank 29, and the mixture is heated with the heat exchanger 31 and supplied to the extraction tank 27. Separately, liquid carbon dioxide is treated with the booster pump 25 and the heat-exchanger 26, and the obtained supercritical gas is introduced into the extraction tank 27 to effect the extraction of the extractable substance with the supercritical gas. The supercritical gas containing the extracted substance is introduced into the separation tank 33, and only the extracted substance is separated under a prssure 1.0-2.0 times the critical pressure at a temperature 1.0-1.2 times the critical temperature. After the separation treatment, the gas is introduced into the extraction assistant-separation tank 35. The carbon dioxide gas is circulated through the valve 36 and the extraction assistant is reused after separation the low-boiling impurities in the separation tank 37. EFFECT:The extraction assistant can be dissolved in the supercritical gas at an arbitrary ratio and an extractable substance free of extraction assistant can be produced.

摘要： PURPOSE:To enhance the extractive decomposition capability and extraction velocity by increasing the pressure of a solvent and then increasing the temp. easily to form a large amt. of a supercritical solvent which is used for extraction. CONSTITUTION:Gaseous carbon dioxide to be used as an extracting solvent flowing from a tank 20 is cooled by a liquefier 21 to form liquefied carbon dioxide. The liq. is filtered in a filter 23 to remove foreign matter. Then the pressure of the liq. is increased to above a critical point by a pump 24 and the temp. is increased by a heat exchanger 25 to a supercritical state to obtain a supercritical extracting solvent. The supercritical liquefied carbon dioxide is brought into contact in an extraction tank 26 with substances to be extracted supplied from a device 27 for supplying the substances to be extracted and a specified component is dissolved and extracted from the substances to be extracted. The liquefied carbon dioxide wherein the substances to be extracted are dissolved is introduced from the extraction vessel 26 to a separation vessel 30 to separate the desired specified component. The separated specified component is stored in a selection vessel 31 and selected.

摘要： PURPOSE:To detect the deposit in a tank accurately and easily by detecting the reflected wave of an ultrasonic wave transmitted to the deposit in the tank and then measuring the required time from the transmission to the reception. CONSTITUTION:A transmitting and receiving sensor 4 transmits the ultrasonic wave to a reference point, e.g. 9a and measures the required time from the transmission of the ultrasonic wave to the reference point 9a the reception, and an arithmetic controller 5 calculates the acoustic velocity in oil by using the distance from the sensor 4 to the reference point 9a and stores the result in a storage device 6. Then, the sensor 4 measures the required time from the transmission of an ultrasonic wave to optional sludge 8 to the reception and the distance is calculated on the basis of said acoustic velocity in the oil which is stored in the storage device previously and stored in the storage device 6. Measurement points of the sludge 8 are changed successively to find the distribution state of the sludge 8.

摘要： PURPOSE:To discriminate variation in source voltage precisely and prevent malfunction by dividing the source voltage through conduction type MOSFETs which are supplied with the source voltage as a bias voltage. CONSTITUTION:The source voltage is divided through series-connected P type FETs Q45 and Q46 which are supplied with the source voltage VCC as a bias voltage and compared by an inverter IV2 with a reference voltage, thereby discriminating variation in the source voltage. Therefore, the semiconductor substrate of single-crystal P type silicon of the integrated circuit of an internal synchronism type dynamic RAM formed on the substrate is not affected by the bias voltage developed in the substrate, and a desired divided voltage of the source voltage is obtained to detect variation in the source voltage accurately, so that the variation in the source voltage is discriminated with high precision. Consequently, a proper timing signal is generated even when the source voltage varies, and the semiconductor integrated circuit of the dynamic RAM is prevented from malfunctioning.
