Disclosed is a method and apparatus for pyrolytically decomposing waste plastic which may contain halogen-containing polymer such as PVC. The plastic is heated at 270&deg; to 350&deg; C., whereby a plasticizer contained in the plastic material is decomposed and vaporized, and a chlorine-containing polymer is dechlorinated to produce hydrogen chloride. The vaporized decomposition matter and the hydrogen chloride are removed from the plastic, and the vaporized decomposition matter is separated from the hydrogen chloride. Then isolated plastic is further heated to 450&deg; C. or higher to produce a pyrolysis product. Alternatively, the former heating step is divided into two steps of: heating at a temperature lower than 270&deg; C., whereby a plasticizer is decomposed; and heating to 270&deg; to 350&deg; C., whereby a chlorine-containing polymer contained in the plastic material is dechlorinated. Accordingly, the decomposition matter of plasticizer and hydrogen chloride are separately removed from the plastic.

Tumor growth in a mammal is inhibited by the administration of an effective amount of xanthocillin X dimethylether. The xanthocillin X dimethylether is administered in a range of 10-3,000 milligrams per day for an average adult human patient. The xanthocillin X dimethylether can be administered orally, by direct application into a neoplastic lesion, or by other parenteral forms of administration including intravenous, subcutaneous, or intramuscular injections. Also, suppository forms can be used.

Method of inhibiting tumor growth using xanthocillin X dimethylether

A method of burning a combustible solid residue from a chemical plant, which comprises feeding a slurry of combustible solid residues in an oil, the amount of the oil being at least 0.5 part by weight per part by weight of the combustible solid residues, into a burner in a combustion furnace comprised of a main combustion chamber having the burner in its arch, a secondary combustion chamber formed in the lower portion of the main combustion chamber, and a flue gas duct provided beneath and following the secondary combustion chamber, burning the residue in the main combustion chamber, conducting the combustion gas into the secondary combustion chamber, and allowing it to reside at a temperature 800.degree. to 1000.degree. C. for at least 0.5 second.

A field-effect transistor-type semiconductor sensor is provided which comprises first and second semiconductor substrates bonded strongly to each other interposing a silicon oxide film therebetween by the use of a direct-bonding technique. The first semiconductor substrate is formed into an island-shape, and incorporates a source region, a drain region and a gate region. The island-shaped substrate constitutes an ion-sensitive portion, and is immersed in a solution when in use. The second semiconductor substrate has openings in which source and drain electrodes are formed.
