Abstract: The hydrophilic organic contaminants and hydrogen peroxide present in semiconductor fabrication reclaims are removed by means of adsorption of a pyrolysate of a macroreticular sulphonated vinyl-aromatic polymer having a carbon content of at least 85% by weight and a carbon/hydrogen atomic ratio of from 1.5:1 to 20:1. In spite of their hydrophobic surface, the pyrolysates have a comparatively high adsorptivity for these contaminants and provide for distinctively higher removal rates than customary activated carbons.

Abstract: In DRAM comprising a read pass transistor, a write pass transistor and a storage transistor, a depletion transistor is connected to a source of the storage transistor. On a part of the source and drain of the depletion transistor, by forming an impurity region of same conductivity as that of the substrate on which the transistors are formed, a substrate voltage applied to the substrate is supplied to the storage transistor through the depletion transistor. An additional metal wire for connecting the source of the storage transistor to Vss voltage(ground voltage or substrate voltage)terminal and a contact hole area for such metal wire are not required. Accordingly, a high integration of the semiconductor can be accomplished and a a reduction of reliability thereof can be decreased.

Abstract: A suspended utility space designed as a captive balloon comprises a carrier balloon which is filled with lifting gas and into which an accessible inner space is incorporated. The carrier balloon is a vertically oriented ellipsoid. The accessible inner space is arranged in the lower part of the carrier balloon. The vertical orientation of the ellipsoidal carrier balloon and the arrangement of the inner space in the lower part of the carrier balloon result in a suspension behavior which is stable under calm conditions. The suspended utility space according to the invention has a larger advertising area visible from the ground and a more effectively utilizable inner space than a spherical airship of comparable size.

Abstract: A fabric-free belt has an oriented polyamide layer (1) as a tension layer. A rubber layer (2, 3) is arranged in the form of a laminate on both sides of the oriented polyamide layer (1).
