Abstract: A decoder circuit for a semiconductor memory device includes input terminal gates (G 00 -G 03 ) which receive address signal bits; first decoder lines (DL1) for decoding output signals of some of the inputterminal gates, and multi-emitter transistors (Ga-Gd, 0 7 ) each having emitter terminals connected to the first decoder lines and a collector terminal connected to a power source and to the base of a transistor (Ga-Gd,Q 7 ) which drives one of a plurality of groups of output terminal gates (G 10 -G 25 ), the multi-emitter transistors turning the driving transistor on or off depending upon the potential of the first decoder lines. Second decoder lines (DLll) are provided for decoding output signals from the remainder (G 02 ,G 03 ) of the input terminal gates. Further multi-emitter transistors (G 10 -G 25 ,Q 7 ) have their emitter terminals connected to the second decoder lines, and each has a collector terminal connected via a resistor to the emitter of the associated transistor (Ga-Gd,Q 7 ) for driving the group of output terminal gates and to the base of an output transistor (G io -G 25 ,Q 7 ), the multi-emitter transistors turning the output transistor on or off depending upon the potential of the second decoder lines and upon the emitter potential of the transistor (Ga-Gd,Q 7 ) which drives the group of the output terminal gates. Diode matrices can be used in place of multi-emitter transistors. In the present invention, constant current sources (I 1 ) are connected to the second decoder lines and emitter-follower transistors (Q 8 -Q 9 ) are inserted between the power source and the second decoder lines and are turned on or off by the output signals of the said remainder of the input terminal gates.

Abstract: 1-Nitrobenzene-2-carboxylic acid alkyl ester-5-carboxylic acid having an alkyl radical in the ester group of 1 to 4 C atoms is prepared by acidic ester-hydrolysis of a 1-nitrobenzene-2-5- dicarboxylic acid dialkyl ester having alkyl radicals in the ester groups of 1 to 4 C atoms in each case, in which the hydrolysis is carried out by means of aqueous nitric acid in particular having a content of preferably 10 to 40%. This process avoids the formation of explosive dimethyl ether, which results from the methanol formed in the hydrolysis of the ester group as in the known processes.

Abstract: Spherical particles of alumina are prepared by agitating a slurry of solids comprising rehydratable alumina solids in water with a hot immiscible liquid to disperse droplets of the slurry in a continuous phase of the immiscible liquid. The droplets are shaped by interfacial surface tension and are hardened by heat while in the immiscible liquid, then are separated and calcined to produce finished spherical alumina beads. The preferred beads are of size less than one millimeter. These are used as supports for catalysts that are used in several oil refining processes such as hydrotreating for removal of sulfur or for reforming or cracking.

Abstract: In a radiation image recording and reproducing method in which a radiation image is once recorded in a stimulable phosphor and then read out and reproduced into a visible image, noise developing in the visible image due to repeated use of the stimulable phosphor is effectively erased by the combined use of first and second erasing steps. The first erasing is conducted to erase the radiation image previously stored in the phosphor, which requires a long period to erase, at an appropriate point of time after the phosphor is once used. The second erasing is carried out quickly to erase the fog, which develops in the phosphor after the first erasing, immediately before the phosphor is to be used for the next radiographic operation.

Abstract: An apparatus for supplying fluid under pressure, such as compressed air, to movable using devices, includes a feed line having tap points spaced along it, with a tap valve at each tap point. A connection unit for connecting the feed line to the user is movable along the feed line and can receive fluid at any tap point. As the connection unit slides into place at the tap point, the tap valve automatically opens to supply fluid. Each valve has a rotary or slide-type valve member movable between open and closed positions, which is always exposed to equal fluid pressure all about it so as to require only a small force to actuate the valve. The valve member is tubular and open-ended and extends parallel to the feed line. Both mechanical and magnetic means for actuating the valve member are disclosed.
