Patent NL-7703942-A (NL)
Title: Semiconductor device with pairs of complementary bipolar transistors - has a high density and has undamaged crystalline surfaces
IPC: H01L21/311
Filed: 1977-04-12
Abstract: A semiconductor is mfd. by providing a surface of a semiconducting zone with a pattern of an electrically insulating material which encloses sections of the zone in the form of islands. The surface is given a doped Si layer, and on this layer, a layer of another material is applied from which an etching mask is formed. Etching then removes those sections of the Si layer which are not under the mask, whilst under etching forms free edges round the mask. The edge of the Si layer and the surface beneath the free edges of the mask are then provided with electrically insulating layer. A first surface zone is produced by diffusion from the doped Si layer and this is followed by the formation of a second surface layer. Doping material is introduced into a zone of the semiconducting surface not covered by the mask, which is limited by the projection of the free edge of the mask; the doped silicon layer being set up, partly on the semiconducting zone in the form of an island and partly on the insulating pattern. After the free edges have been formed by under etching, the insulating layer is applied to the edge of the Si layer and the adjacent surface. The insulating layer is coated with a masking layer and this is subjected to a particle bombardment, during which the edging zone of the etching mask is shielded against this bombardment. Only bombarded sections of the masking layer and then removed by selective etching exclusively from a surface section adjacent to the masking layer, but not under the free edges of the etching mask. Uncovered parts of the insulating layer are also removed; the first and second surface zones having been applied so as to border on the insulating pattern. Minimal number of masking and operational steps are employed in which the splitting off of excess particles of the oxide layer, - a cause of damage to the semiconducting layer - is avoided.

Title: Effluent organic components incineration plant - has compressed air mixed with effluent in nozzle forming swirling droplets reducing fuel usage
IPC: F23G7/00
Filed: 1977-06-20
Abstract: The incineration of organic materials of effluents is controlled by an atomizing burner where the effluent is injected into the flame. The unit leads to optimal destruction of obnoxious materials. The effluent is mixed with compressed air in a jet in the upstream of the burner, and the air velocity is adjusted to ensure the formation of swirling droplets. The ratio of fuel to effluent is then set at 1:5 leading to a drop of temp. in the combustion chamber from 1100 to 900 deg.C. The oil burner (1) operates with air ejector (2) and its tube (3) features a steam feed pipe (8) while tube (4) is provided with oil feeder (9). The ejector is connected to the core tube (10) and has a side inlet (11) for the effluent as well as central inlet (12) for air. The resulting ring jet is mixed in nozzle (19) to provide a stable vortex of droplets in tube (10).

Title: Solid particle separation from aq. liq. by electro:flotation - using electrodes made of carbon fibres giving very fine gas bubble dispersion
IPC: B03D1/14
Filed: 1978-03-29
Abstract: Solid particles are sepd. from an aqs. liq. by electrofloation by charging the liq. below the surface of liq. in a tank contg. electrodes made of carbon fibres, incorporated in a resin electrically insulated matrix. The ends of the carbon fibres are bare over almost the length of the electrode. They are connected electrically to terminals at one end of the electrode. Process is used for clarifying liq. effluents, concentrating activated sludges or recovering proteins, when a dispersion contg. 1% protein can be treated to give a foam contg. 80% solids. Thd carbon fibre electrodes form bubbles of gas which are very finely dispersed in the tank. A sufficient quantity of gas bubbles can be produced by using a lower current density than is needed using metal electrodes. The current can be reversed to prevent the formation of undesirable deposits in the cathode.

Title: Workpiece support used in energy beam machining - made of heat absorbing grains and volatile binder to give clean burr-free holes
Inventor: HOWARD C G
IPC: B23K15/08
Filed: 1980-05-16
Abstract: A support for a workpiece, in which a hole is to be machined by an energy beam, consists of grains (or particles) binded together by a binder which is evaporated by the beam and partially transforms into a liquid after machining.

Abstract: The method is for the detection of a biological substance in an electrically conducting liquid medium capable of containing it. In a measurement cell (1), the said liquid medium (5) is put into contact with a reagent-carrying plate (4) incorporating a specific ligand fixed directly onto one face of a thin layer of dielectric material (4a) whose other face is fixed onto an electrically conducting support. The C and/or R components of the electric impedance of the system consisting of the liquid medium, the insulating layer and the support is measured for a given voltage. The said components are compared with those of a reference system similar to the above system but without the specific ligand. Any reduction in the capacitance or variation in the resistance in comparison with those of the reference system indicates the presence of the said biological substance in the liquid medium concerned. The invention also includes the measurement cell for carrying out the method. <IMAGE>
