IPC: H01L29/74
Filed: 1985-01-31
Abstract: Es wird ein Verfahren zur Herstellung eines Halbleiter-Leistungsbauelementes, insbesondere Thyristor und Gridistor beschrieben. Bei einem solchen Leistungsbauelement soll eine vergrabene Gitterstruktur 10 in das Halbleitermaterial 1, insbesondere Silizium, unter Verwendung einer metallischen Gittermaske 5, 8 eingebracht werden. Erfindungsgemäß ist vorgesehen, daß die vergrabene Gitterstruktur 10, 11 mittels gegendotierender Ionenimplantation 9 unter Verwendung eines Hochenergiebeschleunigers durch die metallische Gittermaske 5, 8 hindurch unmittelbar innerhalb des Halbleitermaterials 1 gebildet wird. Da die Stege 8 der metallischen Gittermaske 5 ein Bremsvermögen der Ionenbestrahlung entgegensetzen, werden zwei vertikal separierte und seitlich gegeneinander versetzte Gitterstrukturen 10, 11 im Halbleitermaterial 1 ausgebildet. Durch den seitlichen Anschliff 7 des Halbleitermaterials 1 werden gleichzeitig die Leiterstrukturen 12, 13 zwischen den vergrabenen Gitterstrukturen 10,11 und der Steuer-/Schaltelektrode 4 ausgebildet, welche sich auf der Unterseite 2 des Halbleitermateriales 1 befindet.

Abstract: The housing (2) of the refrigerator, in particular for installation on a vehicle wheel case and in corner regions, has a recess (4) in the lower rear part to receive the wheel case. In order to obtain as large a capacity as possible and for convenient opening of the refrigerator door, at least one inner surface of the insulated side walls (20, 21) is drawn inwards in the manner of a bead in the region of the door opening and forms a widened joint (22, 23). Expediently, the joints (22, 23), which delimit the door opening, project laterally beyond the door edges, the width of at least one of these projecting joint sections (24) corresponding to the total thickness of the refrigerator door (15, 27) which is provided with an additional facing. <IMAGE>

Abstract: A profiled rubber strip seal for bordering window and door openings. To simplify installation or, for example in the case of sliding windows, to promote relative movement between the strip and window panes, such seals are provided with overlay strips of low-friction material. The sliding properties of the overlay strip are improved, independent of the material of the strip, by applying to the latter a surface texture, for example by impressing such a structural quality in the strip, or by exposing the strip to particles.

Abstract: A linear to A-law and A-law to linear pcm-tdm encoding circuit converts two sixteen bit linear encoded pcm-tdm data streams to one eight bit A-law encoded pcm-tdm data stream having twice as many channels and vice-versa. Incoming bit streams constantly step through the circuit with either A-law encoded or linear encoded data being converted to an intermediate code comprising a sign bit, a chord number and step bits prior to conversion to the desired output encoding. Using shift registers and multiplexers addressed by stored chord numbers ensures minimum delay of the data during conversion.

Abstract: Different diffusion rates can be made operative relative to diffusion disordering in designated areas of a thin active layer or quantum well feature, compared with thermal disordering in other areas thereof where disordering is not desired, by the selective placement of migratory defects in a semiconductor support (12). Such migratory defects as used herein are intended to include impurities and/or other lattice defects initially introduced into the semiconductor support prior to epitaxial deposition of semiconductor layers (22B) constituting the semiconductor structure, wherein at least one of such layers comprises a thin active layer (i.e., a layer with relative high refractive index compared with the refractive index of at least contiguous epitaxially-deposited layers) not necessarily capable of exhibiting quantum size effects or a quantum well feature capable of exhibiting quantum size effects. These migratory defects diffuse or migrate into subsequently-grown epitaxial layers, providing regions of higher lattice defects in the epigrown layers compared with regions of the same layers where no migratory defects were initially introduced into the semiconductor support.

Abstract: A calibrator for a pressurzed water reactor (PWR) core predictor utilizing a distribution expression for the transverse buckling factor, in a one dimensional diffusion model, which has coefficients correlated with overall neutron balance and with a set of power distribution characterization parameters including axial offset, axial pinch, axial quarters and axial fifths. The coefficients are periodically adjusted incrementally one at a time to produce criticality with the model at measured values of rod position, reactor power level, cold leg temperature and boron concentration until the power distribution characterization parameters calculated from a power distribution generated by the model are within preset tolerances of those from a power distribution measurement generated by movable, or if provided, fixed, incore detectors.

Abstract: Herein disclosed is an illuminated push-button switch structure in which, when the push button is pushed, the push-button guide member united to the button is depressed while being supported to slide by the switch base. Then, the switch lever of the switch mechanism associated with the push-button guide member is abruptly turned back with a predetermined depression stroke to afford a switching feel. This turn prevents further movement of the push button in a predetermined depression direction in order to eliminate any undesired vibration of the push button. Even if the push button is obliquely pushed, it is always prevented from being inclined to provide the stable switching operation at all times.
