Patent EP-0068070-A1 (EP)
Inventor: SOCLOF SIDNEY ISAAC
IPC: H01L29/735
Filed: 1982-02-25
Abstract: The invention is a pair of complementary NPN and PNP transistors or arrays thereof and method for producing same in sub-micron dimensions on a silicon substrate selectively doped P and N type by forming first sets of slots (4,5) in spaced apart relation across the N substrate regions to define semi-arrays of intermediate regions which will become transistors. Silicon oxide fills these slots and separates the NPN transistor regions from the substrate. Orthogonal slots (8, 9) divide the semi-arrays into individual transistor active regions which are doped N+ with the doping introduced into each active region via the orthogonal slots and driven in to comprise the emitter and collector regions on respective sides of original substrate. The slots are deepened and P doping is introduced therein to replace the original substrate doping in the active regions, thereby comprising the base regions with the slots deepened into the original N substrate and oxide filled for total isolation. The same construction obtains in the P substrate regions, except first N doping via the slots (101, 102) changes the active regions from P to N, followed by P+ doping for the emitter and collector, slot deepening into the original P substrate and oxide filling for that isolation. Metallization patterns complete electrical connections to the emitter, base and collector regions and silicon oxide substantially covers the periphery of each active region for total isolation. Also, optionally, P + doping may be introduced between the N+ emitter and collector adjacent the substrate surface, and similarly, N+ doping between the N+ emitter and collector.

Abstract: Le procédé consiste à interroger un détecteur de teneur en gaz combustible d'une atmosphère en deux étapes. Dans une première étape le détecteur est alimenté sous une tension faible et on coupe l'alimentation dès qu'un signal positif a été détecté. Dans une seconde étape, si le signal détecté dans la première est négatif ou nul, on alimente le détecteur sous une tension supérieure à celle utilisée dans la première étape. Ce procédé permet de lever toute ambiguité quant aux indications fournies par le détecteur. Le dispositif comprend un détecteur (4), un amplificateur (5) du signal émis par le détecteur, un circuit d'abaissement de tension (1) asservi par l'intermédiaire d'un discriminateur (6) au signe et/ou à l'élongation du signal délivré par l'amplificateur. Application à la détection de la teneur en méthane.

Abstract: The instrument measuring circuit comprises a terminal (A) connected to a support face of this instrument, on which can be disposed a part to be measured, and a terminal (B) connected to a mobile feeler of the instrument, which is intended to measure a dimension of this part. The terminal (A) is connected up to a source of constant current, itself connected to the positive pole of a battery (21) and consisting of the resistor (R1) and of the transistor (T1), the base of which is biased by the operational amplifier (AO1) so as to maintain the point (c) at the reference potential, which is determined by the diode (Z). The terminal (B) is connected to the negative pole of the battery (21) across a resistor (R2). At the instant when the feeler of the instrument comes into contact with the part to be measured, a potential difference appears across the terminals (d) and (e) of the resistor (R2), which is used, on the one hand, to excite the diode (24) and possibly the buzzer (26) by means of the power (AO2) and variable-gain (AO3) operational amplifiers, and on the other hand, to block the displaying of the measurement furnished by the apparatus (12), by exciting the relay (29) across the logic function (32), by choice, either directly or across a bistable flip-flop (34), which it is a question of resetting to zero by pressing the contact button (35). <IMAGE>

Abstract: @ The circuit shown is for use in a system for detecting information stored upon a flexible magnetic media that includes a magnetic transducer for producing an analog signal representing stored binary data, comparator means for detecting positive and negative peaks of the analog signal, and voltage threshold means for providing a reference threshold voltage to the comparator which is a precise percentage of the voltage peaks of the analog signal. The circuit shown generates an improved magnetic recording detection pointer and comprises a pulse width discriminator arrangement which is used to monitor the time per peak during which the analog signal exceeds the detection threshold as an indication of marginal data which can be used in conjunction with an error correction system to extend the overall system correction capability. 
     The circuit comprises an exclusive NOR to which the positive and negative peak value signals P COMP and N COMP are fed and which controls the conductivity of a normally ON transistor 14. When the transistor 14 is held OFF the capacitor 18 is charged and provides a rising signal to the comparator 21. The comparator 21 receives a reference signal from node 22 in a series circuit receiving a threshold voltage V TH  and connected to a current source l c . The output of the comparator is fed directly to flip-flop 28 and via clocked gate 27 to the flip-flop 28. The output of the flip-flop 28 gates data from the latch 30.

Abstract: A buckle for securing banding under tension around an article, comprises a sheet steel plate (36) with a bridge (40). One end of the band (34) is initially secured to the buckle and the free end passed around the article and threaded under the bridge, where it is then tensioned by a conventional banding tool. The free end is then secured by pivoting the tool so as to bend the band around the bridge. The top of the bridge has a recessed edge (45) so that only the lower jaw (12) engages the bridge, more specifically the edges (43) of the sides of the bridge, during tensioning and initial pivoting. The recess accommodates the thickness of the strap on bending and eliminates the need to slacken off the tension in the banding tool to avoid overtensioning or breakage.
