Abstract: Methods and products are provided for producing and/or purifying virtually any hybrid polypeptide molecule employing recombinant DNA techniques. More specifically, a DNA fragment coding for a protein molecule, e.g. a polypeptide or portion thereof, is fused to a DNA fragment coding for a binding protein, such as the gene coding for the maltose binding protein. The fused DNA is inserted into a cloning vector and an appropriate host transformed. Upon expression, a hybrid polypeptide is produced which can be purified by contacting the hybrid polypeptide with a ligand or substrate to which the binding protein has specific affinity, e.g. by affinity chromatography. The hybrid polypeptide so purified may in certain instances be useful in its hybrid form, or it may be cleaved to obtain the protein molecule itself by, for example, linking the DNA fragments coding for the target and binding proteins with a DNA segment which codes for a peptide which is recognized and cut by a proteolytic enzyme, such as Factor Xa.

Abstract: In a small-sized computer of a natural air-cooling type, a high-temperature radiator promotes natural convection so as to increase a quantity of heat radiation and to raise the allowable limit of heat generation of LSI chips, thereby improving the processing speed of the computer. For this purpose, a casing and fins are utilized as heat radiators at relatively low temperatures of about 40.degree. C. which are safe even if they are touched by an operator's hands. On the other hand, the high-temperature radiator set at about 50.degree. to 60.degree. C. is provided inside of the casing, thus preventing the operator's hands from touching it directly. Heat generated by the LSI chips and so forth is transmitted to the high-temperature radiator through heat conduction or the like, and heat exchange is performed between the high-temperature radiator increased in temperature and the air introduced into the casing, in order to promote natural convection inside of the casing.
