Abstract: A process is claimed for prodn. of bipolar transistor structures with self-adjusting emitter-base regions, in which both the emitter and the base regions are produced in the silicon semiconductor substrate by diffusion from structures which consist of doped polysilicon layers deposited directly on the substrate and which form the subsequent connections. SiO2 layers are used as masking and insulation layers to produce first the base region and then the central emitter region so that symmetrical active and inactive base zones are formed below the emitter region. Dry etching processes are used to produce vertical etch profiles during structuring of the SiO2 and polysilicon layers. The novelty is that, after prodn. of the polysilicon layer structure forming the emitter connection, the polysilicon layer structure forming the base connection is exposed by etching using the emitter layer structure as mask and that, after prodn. of flank insulation layers on both layer structures, the exposed silicon surface is selectively provided with a metallic conductive layer. Also claimed is prodn. of bipolar transistors with buried collector regions and deep-lying collector connections.

Abstract: In the distributor tube, to deliver fluid and partic. molten spinning fluids through a number of outlets, a fluid layer is formed close to the wall before a selected outlet and then allowed to flow through. Specifically, tubular inserts, at the level of each outlet and in the direction of each, are placed in the distributor tube, with a smaller dia. than that of the distributor tube. The tubular inserts have an inner dia. of 60-80% of the inner dia. of the distributor tube, and the outer dia. of the inserts is 5-40% greater than their inner dia.  The tubular insert length is 30-80% of the gap between the outlets, and inserted into each outlet by an amount which is 0-95% of the insert length along the direction of fluid flow.

M is a mixture of metalloid elements the main component of which is B, and z=4-9. (2) the pulverised product is oriented-compression-moulded in a magnetic field or compression-moulded in a non-magnetic field, and then (3) sintered at 900 to 1200 deg.C, (4) the product is then ground and polished into a suitable shape (5) following by solution heat treatment at 900 to 1200 deg.C at a pressure of 10 power (01) -1 Torr oxygen and/or nitrogen; (6) and then aged at 300 to 900 deg.C. Process (4) and (5) can be exchanged. As a result of these processes an oxide and/or nitride film of thickness 0.001-0.1 microns is formed on the surface of the magnet.

Abstract: A branch-off connector for an electric power cable has two half shells containing moisture resistant sealing gel that are clamped around the branch-off region to form a sealed housing. A pre-terminated branch cable may be mounted in one of a plurality of orientations on the housing. Electrical connection to the main cable, and thus energisation of the branch cable, can be made subsequently to sealing of the housing around the branch-off region by insulation - piercing screws retained within the housing. Further branch cables can be added to, or branch cables removed from the connector, without disturbing the sealing of the branch-off region of the main cable.

Abstract: A controlled stream of liquid cryogen is delivered from a system comprising: (a) a source of liquid cryogen at a substantially constant pressure, remote from the outlet; (b) a conduit connecting the liquid cryogen source to the outlet; (c) means to maintain cryogen flowing through the conduit sub-cooled at all points along the conduit (i.e., at any given point in the conduit, the cryogen's equilibrium vapor pressure is below the pressure experienced at that point in the conduit), and to deliver the cryogen to the outlet at a temperature equal to or below its boiling point at atmospheric pressure; and (d) a flow-rate control restriction, positioned in the conduit. By maintaining the cryogen sub-cooled, the flow is kept substantially (at least about 95% by volume) liquid. Therefore, the flow in the conduit is controlled reliably as to pressure, flow rate, and size. Specifically, the rate at which liquid cryogen is delivered at the outlet is controlled by the cross-sectional area of the flow-control restriction, and severe flashing at the outlet is avoided.

Abstract: In a system where a received signal is decoded using a clock signal, a second clock signal is produced whose frequency corresponds to the clock signal of the sentout data signal, continuing independent of the prevailing reception conditions. On the occurrence of interference in the received data signal the second clock is utilised for the decoding of the data. The second signal may be used when the interference exceeds a predetermined threshold, such as when the phase deviation of the first clock deviates shaped the second by more than a preset value. For producing the second clock signal there may be provided a controllable quartz oscillator and a phase and frequency comparator forming a loop.

Abstract: The portable radiation measurer includes two Geiger-Muller tubes, each connected to a pulse shaper generating outputs dependent on radiation intensity. The pulses are received by a high speed counter. restarted each second to provide count rates to a microprocessor. The microprocessor switches in that tube most appropriate to the detected intensity, and stores measurement algorithms. The latter provides an integration period over which current mean values of counts per second are calculated. Upon occurence of an abrupt charge in intensity, the integration period is reduced until substantially stable values, lying between tolerance thresholds, are again observed.
