Title: Education device for teaching reading and writing skills
Inventor: HARELI GADI
IPC: G09B5/04
Filed: 1991-08-14
Abstract: An educational device for aiding the development of reading and writing skills, comprising a plurality of symbol blocks each having an alphabetic symbol representing a predetermined consonant-vowel combination on at least one surface thereof and having associated with each surface bearing a symbol thereon a respective predetermined encoding means. Also provided is a casing containing a plurality of receptacles each for displaying a surface of a respective one of the symbol blocks inserted therein, and a plurality of decoding means within the casing each associated with a respective one of the receptacles and responsive to the encoding means of the symbol block inserted therein for generating a code corresponding to the alphabetic symbol appearing on the displayed surface of the symbol block. Each receptacle is scanned in turn at a preselected speed depending on the proficiency of the user, so as successively to couple a synthesizing means to each of the decoding means for synthesizing a sound corresponding to the alphabetic symbol represented by the code in response to the generated code. The resulting sound is reproduced audibly by an audio output means coupled to the voice synthesizing means.

Abstract: Circuit de terminaison pour un réseau en échelle R-2R pour produire des courants pondérés, la résistance à terminaison 2R de l'échelle étant connectée à une tension de source d'excitation qui est 2(kT/q)ln2 plus proche de la tension d'alimentation que l'émetteur de la source de courant dans la dernière (c'est-à-dire la moins significative) jambe de l'échelle. La source d'excitation est fabriquée avec seulement un type de transistor bipolaire et n'a pas besoin d'un amplificateur ou de condensateurs de compensation de fréquence. La source d'excitation est un circuit simple nécessitant uniquement cinq transistors, dont au moins l'un possède une région émettrice qui est un multiple des régions émettrices des transistors de la source de courant. Les tensions base-émetteur des transistors dans la source d'excitation sont connectées dans une boucle de tension qui va depuis une tension VLSB au niveau de l'émetteur du transistor de la source de courant connectée à la résistance de dérivation du réseau en échelle la moins significative jusqu'à une tension, Vt, qui serait égale à VLSB, si tous les six transistors dans la boucle avaient la même région émettrice, mais qui s'en écartent de 2(kT/q)ln2 à cause des différences dans les régions émettrices.

Abstract: Convertisseur (10) de fréquence décalée pour étapes de fréquence intermédiaire (FI) d'un récepteur (8) de mesure phase/amplitude de radiofréquence (H.F.) à canaux multiples. Le convertisseur permet d'employer des sources d'oscillateur locales d'émetteur et de récepteur non cohérents utilisant des synthétiseurs de fréquences numériques; il permet le mélange harmonique. Le convertisseur échantillonne un premier signal de fréquence intermédiaire entrant FI1 dans un canal de référence (38b). L'échantillon FI1 est alors converti en une fréquence plus haute, filtré et reconverti en un signal FI1+FI2 décalé de l'échantillon FI1 d'une deuxième fréquence intermédiaire plus basse FI2. Le décalage de fréquence ajouté FI2 provient d'une source stabilisée dans le temps indépendante de l'émetteur mais cohérente avec le récepteur LO. On superpose au signal mélangé FI1+FI2 des signaux tant dans le canal de signaux (38a) de l'antenne à l'essai que dans le canal de référence afin d'obtenir des sorties cohérentes sur FI2 qui diffèrent par leur phase et leur intensité des caractéristiques correspondantes de l'antenne à l'essai.

Abstract: The stopper (1) contains as a tamper-proof safeguard a frangible securing ring (4) which surrounds the edge of the container mouth. The securing ring (4) is provided with an inwardly facing annular bead (15) which engages below an outer annular projection of the container. The stopper (1) has an olive-shaped boss (6) which engages in the container mouth in the clamping fit and a slide (3) which serves as child-resistant safeguard and can be pushed beyond the edge of the container mouth, when the tamper-proof securing ring (4) has been removed, in order to overcome the clamping fit in the container mouth. In order that the stopper (1) cannot be "levered off" from the container without damaging the securing ring (4), said securing ring (4), in addition to a cylindrical wall section, has a circular wall section (11) which is bent inwards by 90 DEG  and is connected to the top part of the stopper via a circular intended tearing seam (13). A circumferential blocking section (5) of the securing ring (4) has a circular wall section of greater wall thickness which is not connected to the top piece and merges via a film hinge (14) into the cylindrical wall section. In the attachment position of the stopper (1), the freely ending circular wall section is inevitably folded up into the path of movement of the slide (3) so that the latter cannot be pushed forwards. In an attempt to "lever off" the stopper (1), the circular intended tearing seam (13) would inevitably be torn open.

Abstract: A method for the selective deposition of chemical vapor deposition (CVD) diamond on a surface of a substrate comprises the steps of masking an area of said surface with a coating material that prevents CVD diamond formation and subjecting the substrate to a CVD diamond deposition process for coating a layer of CVD diamond on the substrate in the unmasked areas only. 
Advantageously, the surface first is coated with a layer of material that promotes CVD diamond formation and then the coated substrate is subjected to the masking step. Advantageously, the substrate comprises a twist drill wherein the surfaces perpendicular to the main shear planes involved in drilling, such as the planes forming the cutting edge of the drill, are coated with CVD diamond while the remaining areas of the twist drill remain uncoated.
