Abstract: A screw, whose tip (23) is designed as a drill and whose thread pitches (26) are designed relatively sharp so that they can tap a thread in relatively soft materials such as e.g. plastic. The drill tip (23) has a rear section (24) (length l1), whose diameter is constant and a front section (25) (length l2), which tapers towards the screw tip. The complete drill tip is provided with a thread (27) whose external diameter is smaller than the external diameter of the thread (26) which is located between the drill tip (23) and the screw head (21). The screw is drawn into the material to be drilled by means of the thread pitches (27) at the drill tip (23) so that there is no need to exercise any feeding force. The drill tip (23) can be provided with a swarf groove (28) which forms a cutting edge (28a). The swarf groove (28) allows thermoplastic synthetic materials to be drilled at high speed without any unacceptable heating. <IMAGE>

Abstract: Die Erfindung betrifft eine Belüftungsvorrichtung für Abwasser mit in einem Trog rotierenden, trommelartigen Rotor, der durch achsparallele Trennwände in mehrere außen offene, radiale Kammern unterteilt ist und dessen Trennwände mit bei Eintauchstellung nach unten weisenden Außenabschnitten versehen sind, so daß im nachlaufenden Teil der Kammern ein Luftvolumen in die Flüssigkeit mitgenommen wird. Dieses Luftvolumen würde beim unteren Totpunkt plötzlich und fast vollständig aus dem Trog entweichen, was zu unzureichender Belüftung und hoher Antriebsleistung führen würde. Nach der Erfindung haben die Trennwande (10-15) zusätzlich einen bei Auftauchstellung nach unten gerichteten Abschnitt (36-41). Dadurch bleibt ein Teil des Luftvolumens (55) bei Auftauchbewegung im verlaufenden Teil der Kammern (16-20) gefangen. Bei der Luftverlagerung innerhalb der Kammern kann durch Leitbleche (42-47) ein noch besserer Belüftungsgrad erreicht werden.

Abstract: The invention provides a unique sub-micron dimensioned NPN type transistor and method of making the same wherein hundreds of such transistors may be fabricated on a single chip with each transistor comprising an active region surrounded by field oxide completely isolating it from the substrate and its effects on operation. Slots made in the substrate permit angle evaporation of etch-resist to protect the active region while it is disconnected from the substrate by etching therebeneath via the slots. Substrate oxidation supports the active regions while orthogonal slots are provided permitting access to opposed sides of the active regions for doping P+ which is driven in from one side only while N+ is introduced and driven in from both sides, thereby providing an N+ P+P, N+ emitter, base, collector transistor active region to which electrical connections are applied using conventional techniques, providing almost complete reduction of the parasitic capacitances and resistances because of the total oxide isolation of the active regions from the substrate.
