Abstract: Synthesis gas comprising hydrogen and carbon monoxide is produced from a raw, partially dehydrated synthesis gas by removing carbon dioxide and residual water in a pressure swing adsorption (PSA) system wherein regeneration is effected by purging with essentially pure methane. Purge effluent comprising CO₂ and methane is recycled as feed to the raw synthesis gas generation process. In another embodiment, purified synthesis gas so generated is separated cryogenically into individual hydrogen and carbon monoxide products, and reject gas from the cryogenic separation step also is used for purging said PSA system with purge effluent being recycled as feed to the synthesis gas generation process. In a further embodiment, raw synthesis gas is subjected to water gas shift, and CO₂ and residual water are removed in a PSA system yielding a hydrogen product. The PSA system is purged with methane and the purge effluent is recycled to the synthesis gas generator as fuel.

Abstract: A data transmission control processing system is described which can easily realise the reading from and writing to the memories of other terminals in a network. The proposed system provides for writing to the memory of the other terminal in a way which is similar to the memory reading sequence of the D2B system, and thus simplifies the realisation of the reading/writing control sequence while reducing the number of control messages which are necessary. The system can easily cope with possible future expansions in the number and type or read/write control signals.

Abstract: This invention is directed to a process of producing semiconductor devices which involves deposition of protective glass layers by a particle beam technique from targets of phosphosilicate glass, as well as a process for production of such targets. The phosphosilicate glass containing 1-15 mole percent P₂O₅ is produced by a sol/gel technique which involves mixing of a fumed silica, with a surface area of 50-400 m²/g, preferably about 200 m²/g, with phosphoric acid and water to form a sol with 20-55 wt. % silica, allowing it to gel, drying at ambient conditions, dehydrating at about 650°C in an atmosphere of an inert gas and chlorine and fluorine containing gases, heating up at a certain rate of from 100 to 180°C per hour to a peak sintering temperature below 1200°C and cooling so as to produce amorphous and transparent glass suitable for use as a target. The glass layers are highly advantageous as encapsulating layers, diffusion barrier layers, etc., especially for optical type and semiconductor devices. Production of the phosphosilicate glass by the sol/gel technique is highly advantageous over the conventional melting technique, being faster and much less expensive than the latter.

Abstract: A structure connecting superconductor transmission lines to integrated circuits comprises a plurality of interconnection substrates having superconducting transmission path deposited thereon in contact with metallic contact areas, and integrated circuit chip carrier substrates for mounting integrated circuits and having metallic contact areas. The substrates are mounted in a retainer structure and are separated by spacers which have apertures in registration with the contact areas. Contact devices are selectively inserted in the apertures to establish an interconnection pattern between the substrates. The retainer structure applies force to the substrates to assure physical contact between the substrates and the contact device. The structure may be assembled and disassembled for replacement of parts or reconfiguration of interconnections, without the application of heat or other processes which are incompatible with relatively brittle and heat sensitive superconducting materials. The complete structure may be submerged in a bath of liquid nitrogen for cooling. The space provided by the spacers allows for access by the cooling liquid to the superconducing material on the substrates.

Abstract: In an optically-excited micromachined silicon pressure sensor comprising a resonantly vibrating beam mounted on a diaphragm, vibration of the beam is sensed optically via the same optical fibre through which the optical excitation signal is applied to the sensor. The end of the fibre and the beam are arranged to define a cavity or gap whose width varies with vibration of the beam and which behaves as a Fabry-Perot cavity: thus light from the fibre is directed onto the beam and then reflected back to the fibre, the reflected light being modulated at the frequency of vibration of the beam. In order to overcome the difficulty of setting the gap or cavity width at an optimum value for light of a given wavelength, light of two different wavelengths is used to sense the vibrations, the wavelengths being selected such that the phase difference produced by the gap for one wavelength differs from that for the other wavelength by roughly 90°.

Abstract: Tapered via holes (10) of uniform diameter are formed in a dual-layer (SiO₂/SiNi) dielectric (18, 20) used for isolation of metallization layers in an integrated circuit. The method includes forming a photoresist layer (22) atop the nitride layer (20) and patterning the photoresist to define a via hole (24). The nitride and oxide layers are successively plasma etched through the photoresist-defined via holes (24) to form via holes (26, 28) through the dual-layer dielectric to an underlying metal line (16, 17). Etching of the nitride layer is selective to the oxide layer. Etching of the oxide layer is selective to the metal line. The photoresist and nitride layers are etched simultaneously in the presence of oxygen so as to taper the via hole in the nitride. The oxide is etched in the absence of oxygen, producing a tapered sidewall profile (32) extending continuously to the metal.

Abstract: In a method for rolling hot wide strip starting from continuously cast thin slabs in successive working stages of a finishing train, cast strands are produced in one or more casting machines or casting lines and individual thin slabs cut from them, homogenised in a soaking furnace, brought to the rolling temperature and transferred to the rolling line. A very high degree of flexibility with matching of the casting capacity and rolling capacity is here achieved by the fact that thin slabs are transferred by pivoting into an oblique switch position a pivoting roller-hearth furnace provided in a casting line and a pivoting roller-hearth furnace provided in the rolling line, transfer being effected alternately from one of the casting lines into the rolling line via both pivoting rolling-hearth furnaces. An installation advantageously has one pivoting roller-hearth furnace (4a, 4b, 5) for each casting line A, B, C and for the rolling line x-x and these furnaces are offset longitudinally relative to one another by a distance corresponding approximately to the length of a pivoting furnace, the pivot points of pivoting furnaces (4a, 4b) being arranged at their rear ends (6a, 6b) and the pivot point (3) of the pivoting furnace (5) being arranged at its front end (7).
