Abstract: ABSTRACT      A diode has at least a first region and second region with the regions abutting each other to form a junction therebetween and with the first region being made of an amorphous alloy including silicon and fluorine.  Such a diode finds particular use-fulness in closed cells in a ROM or in a EEPROM device having a memory circuit at each cross over point of a conductor of a first group of conductors in a memory matrix extending in a first direction over a conductor of a second group of conductors extending in a second direction traversing the first direction.  The first group of conductors is insulated from the second group of conductors and each memory circuit is coupled to and between a pair of crossing over conductors at one of the cross over points and includes a memory region and the diode.  Preferably, the amorphous alloy also contains hydrogen and such alloy is a-Sia:Fb:Hc, where a is between 80 and 98 atomic percent, b is between 0 and 10 atomic percent and c is between 0 and 10 atomic percent.     The first and second alloy regions of can be oppositely P and N doped.  Alternately, one of the regions can be a metal, metal alloy or a metallic like material to form a Schottky barrier with the other region or MIS junctions can be utilized.

Abstract: ABSTRACT:             A surface acoustic wave bandpass electrical filter consists of input and output interdigital trans-ducers (IP, OP) with an interposed track changing multi-strip array (MSA).  A conventional broadband array (MSA) is divided into two sub-groups of strips with respect to a centre of symmetry (C) separated by different distances along the input track (T1) and the output track (T2) such that the amplitude-frequency response of the array (MSA) has a stopband centred on a predetermined frequency.  If the input and output transducers (IP,OP) both have a double electrode configuration, electrode separation .lambda.o/4, providing a fundamental passband at a corresponding fre-quency fo and an equal amplitude passband at the third harmonic 3fo, then a separation difference of .lambda.o/6 between the sub-groups of the array (MSA) in the two tracks (T1,T2) can suppress the third harmonic passband in the filter output.  The multistrip coupler may instead be divided into three sub-groups.  The sub-groups of the multistrip array may be further sub-divided to suppress more than one frequency.  Also a multistrip array arranged in groups to provide a shaped bandpass response may have each group divided into sub-groups to suppress a selected harmonic passband of the array.

Abstract: ABSTRACT OF THE DISCLOSURE          Photographic processing compositions, such as developing compositions, fixing compositions, bleacning compositions, bleach-fixing compositions, stabilizing compositions, and the like, are prepared in the form of a stable paste that is adapted to be diluted with water or other liquid medium to form a working processing solution.  The paste composition utilizes the association of finely-divided solid par-ticles in a stable three-dimensional network to provide advantageous characteristics of both a physical and chemical nature.  It provides major economic advantages as compared to liquid concentrates with regard to pack-aging, transporting, and storage considerations and, in view of the convenience in handling and the ease with which it can be converted to a working solution, is substantially superior to a dry powder mix.

Title: Methode d'elimination d'effluves d'effet couronne par   fibre generatrice de decharges luminescentes  declenchee par mouillage capillaire

Abstract: L'invention a pour objet une méthode d'élimination des décharges partielles pulsatives de l'effet couronne sur les conducteurs métalliques d'une ligne aérienne de transport d'électricité à haute tension lorsque les conducteurs sont mouillés. Cette méthode consiste à fixer en contact intime avec chaque conducteur une matière fibreuse et non conductrice ayant un effet capillaire pour l'eau. L'effet capillaire de la matière fibreuse ainsi fixée assure la formation de fins filaments d'eau issus de la surface du conducteur lorsque ce dernier est mouillé. Ces filaments d'eau assurent à leur tour une génération de l'effet couronne sous forme de décharges permanentes se manifestant par un phénomène de luminescence plutôt que sous forme de décharges pulsatives. Cette méthode est particulièrement intéressante dans la mesure où elle réduit substantiellement le bruit audible et les interférences électromagnétiques générées par effet couronne à proximité des lignes aériennes de transport lorsqu'il pleut ou qu'il bruine, sans pour autant altérer les performances de la ligne de transport lorsque le temps est sec. L'invention a également pour objet un conducteur pour ligne aérienne de transport d'électricité à haute tension, permettant de mettre en oeuvre la méthode ci-dessus décrite.

Abstract: FRAMING CIRCUIT FOR DIGITAL RECEIVER            Abstract The possibility of framing a receiver on a false pattern either generated, for example, by a data subscriber, or simply one statistically occurring in the normal digital transmission is minimized by employing a cyclical-redundancy-check (CRC).  Bits of a presently received time division signal are compared to bits of a CRC code word generated from the last previously received block of bits of the time division signal to generate error indications.  When a predetermined number of CRC error indications is detected, i.e., loss of CRC, the framing bit pattern the receiver is synchronized with is considered a false pattern and reframing of the receiver is initiated. This process is iterated until no loss of CRC is detected for the framing bit pattern that the receiver is synchronized with.  In a specific example, a 6-bit CRC code word is employed.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention is concerned with a method for detecting a conductive mineral or metal in a soil and for discriminating the magnetized minerals from the so detected conductive mineral.  According to this method, a high-frequency signal is continuously transmitted with an oscillator comprising a loop whose inductance varies in the presence of a conductive mineral at the vicinity thereof while the high-frequency signal is continuously received, the loop is moved away from the soil and the frequency of the received signal is counted to give a reference value.  Then, the frequency of the received signal is counted again while moving the loop over the soil to obtain an updated value.  This updated value is continuously compared with the reference value; and an output signal is gi-ven whenever the updated value is higher than the reference value.  The invention is also concerned with an apparatus for carrying out the above method.
