Patent EP-0092671-A2 (EP)
Inventor: WERNER WOLFGANG DR ING
IPC: H01L29/36
Filed: 1983-03-16
Abstract: The basis of the invention is a bipolar transistor structure suitable for ICs as described in German Offenlegungsschrift 3,029,553. For this structure it is essential that the base zone has a larger lateral cross sectional area than the buried zone (buried layer) situated beneath it at a distance and serving to reduce the collector spreading resistance. In addition, it should extend laterally beyond the buried zone at all points along its edge. These measures result in a parasitic junction field-effect transistor which ensures that the transistor acquires an appreciable increase in its breakdown voltage. The object of the invention is to achieve a yet further increase in the breakdown voltage. For this purpose, according to the invention, the doping of the epitaxial semiconductor layer accommodating the transistor with the exception of the buried zone and, consequently, the background doping as well as the substrate doping are matched to one another in a manner such that, because of an operating voltage which is already markedly below the CE breakdown voltage, an interaction is produced between the space charge zones which, on the one hand, emanate from the base-collector junction and, on the other hand, from the substrate-collector junction during the operation of the transistor. <IMAGE>

Abstract: A ball mill stator providing a milling space between a housing and a cover and a ring-like displacing body in the milling space with a V-shaped radial cross-section forming part of the rotor. The material being milled together with the balls flows around the displacing body from a feed inlet to an outlet along spiral paths. The milling media kept back at the milling gap are moved through a duct into an annular space and from this point through conveying ducts of an impeller outwards and re-enter the milling space at a small distance above the feed inlet. The impeller is sealed between the rotor and stator and is powered by a motor, or by a variable speed drive, run at a speed controlled by readings taken from different parts of the mill system such that the milling media is evenly distributed in the material being milled by which they are moved along making the milling operation more uniform and efficient. An adjustable milling ring together with the impeller form a coarse milling unit whose gap size may be changed like that of the inlet.

Abstract: This idea relates to a heat detector using an optical fiber as heat sensitive line, in which a modulation light is emitted from a light emitting element through the optical fiber, and output of the photoelectric element is checked for attenuation. This detector is capable of readily discriminating a fire by attentuation of the light from the light source caused by damage in the optical fiber in case of fire.

Abstract: A fabric having anti-static properties being formed from a first woven layer of polymeric fabric, a second woven layer of polymeric fabric which contains spaced threads of staple metal fibres and an intermediate layer positioned between the first and second layers to form a moisture barrier. In its most preferred form the woven polymeric fabric is formed of woven polypropylene and the spaced threads of staple metal fibres are formed of staple stainless steel fibres carried on a central core of a synthetic material. The fabric is of particular use in the manufacture of intermediate bulk containers where it is believed is advantageous in permitting corona discharge at a very low voltage of static electricity thereby preventing any dangerous build-up of voltage which subsequently is discharged by a spark.

Abstract: @ A recording circuit for a video tape recorder which records superposedly a frequency-modulated audio signal with a frequency-modulated luminance signal and a carrier color signal converted to a low frequency band records a carrier wave signal which is frequency-modulated by the luminance signal at a substantially constant recording current within the frequency range corresponding to a range from the sync signal leading edge to the white peak. In an ordinary recording circuit, the extent of erasure of the recorded audio signal varies with the content of the frequency-modulated luminance signal when the luminance signal is recorded on the recording track of the frequency-modulated audio signal, because recording is made by increasing a recording current for a signal having an instantaneous frequency which is low. Therefore, the recorded signal which is frequency-modulated by the audio signal is amplitude-modulated by the luminance signal, and interference with the audio signal due to the change of S/N corresponding to the change of the amplitude occurs. In the recording circuit of the present invention, however, no interference is applied to the audio signal because the extent of erasure of the recorded audio signal by the luminance signal remains substantially constant irrespective of the content of the luminance signal.

Abstract: @ Vibrating beam force sensors have a relatively low Q unless there can be prevented energy loss to the mountings at either end of the beam. This can be achieved by providing some sort of counterbalanced vibrating element; the available beam structures, which are all quite complex, involve balancing beams or counterweights that are in the vibrational plane of the 'main' beam, and flex in that plane. 
     The invention provides a mechanically simpler but no less efficient beam structure by placing counterbalancing beams not above and below the main beam but on either side thereof.

Abstract: A self-feeding water-heating boiler for dispensing hot water for beverage making purposes includes a main boiling chamber (62) which communicates through a steam pipe (90) with an overhead steam condenser (64). Incoming fresh feed water is delivered to the condenser (64) from which is passes through an outlet (108) to a feed tank (65) for feeding to the boiling chamber (62) but the condenser (64) is so constructed as to trap a quantity of the feed water below the level of the outlet (108) to provide a permanent pool (100) of coolant. In one embodiment, a baffle (96) traps steam entering the condenser and ensures that it can only escape by bubbling through the coolant water pool (100).

Abstract: An immunoassay utilizing a novel liposome composition in which there is incorporated a stabilizing or destabilizing component and an antigen. The presence of cognate antibodies in test samples is detected by the alteration of the supramolecular structure of the liposomes resulting in changes in stabilization. Destabilization can be detected, and in certain cases, caused by, the addition of magnesium or calcium ions. Increased stabilization can be detected by the polymerization of bilayer components in response to ultraviolet light. Antibody-antigen interactions at the liposome surface mediate the stabilization/destabilization response.

Abstract: There is disclosed a new process for the conversion of the organic components of sludge, particularly sewage sludge, to produce useful, storable, energy-containing oil products, apparatus for carrying out the process and a control process for optimisation of the process temperature. The sludge preferably is mechanically dewatered to about 20-25% solids by weight and thermally dried to about 90% solids by weight. The resultant material is comminuted and heated in the apparatus of the invention to at least 250°C in a heating zone in the absence of oxygen to generate a gaseous atmosphere containing volatiles; this atmosphere is then removed, scrubbed of H 2 S and NH 3  if required, and passed preferably in countercurrent flow in a heated reaction zone in intimate contact with the «devolatilized» sludge solids from the heating zone, again in the absence of oxygen, at a temperature of at least 280°C, resulting in catalysed vapour phase oii-producing reactions. The oil vapours are carried out by the gas flow and condensed. The preferred apparatus moves the sludge solids cocurrent with the heating zone atmosphere and countercurrent with the reaction zone atmosphere. In the reaction zone the conveyor not only moves the comminuted sludge along but lifts it and drops it through the gaseous atmosphere for the preferred intimate contact. Preferably the sludge is examined repeatedly by differential scanning calorimetry to generate a thermogram which has been found to reveal immediately the optimum temperature for operation of the reaction zone, and also the anticipated oil yield from the sludge.
