摘要： In a method using a chromatographic separation apparatus consisting of plurality of unit packed beds each having a supply inlet/extraction outlet, wherein the apparatus is effectively divided into four zones; an adsorption zone, a refining zone, a desorption zone, and a concentration zone. A supply and extraction step is performed in which all of the fluid flowing out of the adsorption zone is extracted through the nonadsorbate fluid extraction outlet, and then a recycle step, in which no fluid is supplied to or extracted from the bed, is performed to move the concentration distributions in the bed to a desired position. As a result, the method requires fewer unit beds, and enables extraction of components of higher purity.

摘要： The method of chromatographic separation comprises: a feed-withdrawal step in which, with liquid flow being permitted from the first to the third unit beds in the simulated moving bed, an eluant is fed into the first unit bed and the feed stock is fed into the third unit bed while, at the same time, part of the effluent from the first unit bed is withdrawn from the system as a fraction rich in component B and the effluent from the third unit bed is withdrawn from the system as a fraction rich in component C; a circulation stage in which, with liquid circulation being permitted through the simulated moving bed, the liquid in the simulated moving bed is moved downstream without liquid feed to or withdrawal from the simulated moving bed; and a withdrawal stage in which, with liquid flow being permitted from the second to the first unit beds, the eluant is fed to the second unit bed and the effluent from the first unit bed is withdrawn from the system as a fraction rich in component A; wherein, after the above three stages are performed, the same stages are repeated except that feed stock and eluant are fed to, and effluents are withdrawn from unit beds which exist immediately downstream of the respective corresponding unit beds.

摘要： A chromatographic separation process employing fewer beds packed with an adsorbent, while enabling separation of feedstock fluid, containing a plurality of components which have different degrees of affinity for the adsorbent, into constituent fractions which are withdrawn separately. According to at least one preferred embodiment, a step of supplying feedstock fluid to the simplified separation apparatus is preceded and followed by a step of circulating the fluid through the apparatus, a cycle of supply-desorbing-circulation being carried out repeatedly.

摘要： An insulating film is formed on a semiconductor substrate, and the insulating film on that part of the semiconductor substrate where an emitter is to be formed, is removed to expose the surface of the above part. A polycrystalline or amorphous silicon film is deposited on the entire surface, and then irradiated with a laser beam to convert that portion of the polycrystalline or amorphous silicon film which is deposited on the surface of the semiconductor substrate without interposing the insulating film therebetween, into a single crystal of silicon, thereby forming a stacked emitter.

摘要： A region containing a high concentration of impurity and a desired region adjacent thereto are fused by irradiation with a laser beam, to diffuse the impurity in the lateral direction into the desired region and to render the desired region a low resistance.Since this method can execute only the lateral diffusion of the impurity without affecting other portions, it is very useful for forming a high breakdown voltage MIS-FET, a resistor etc.
