Abstract: A current-switching type compound semiconductor logic circuit which is high in an operating speed and low in power consumption. Voltage stabilizing transistors (25,26) are provided to the logic circuit so that voltage signal which are in-phase with the gates of driving transistors (21,22) and has a mean electric potential higher than that of the same by a predetermined value is applied to the gate thereof. The voltage stabilizing transistors (25,26) act as a buffer to prevent electric potential of the driving transistors (21,22) from fluctuating. As a result, it is possible to secure stable outputs in which the distortion of a waveform or the fluctuation of a cross point due to a jitter is hardly generated.

Abstract: An optical type position detecting device comprising a light source (14), and a light-receiving element (15) for detecting a light beam emitted by the light source, a region (20) on the light-receiving element (15) whereon the light beam is incident having parallel boundaries (20a,20b), the boundaries extending in directions substantially corresponding to directions of relative displacement of the region and the light-receiving element, the relative displacement accompanying a displacement of a body. The relative displacement can be detected by detecting a change in area of the region using the light-receiving element. A magnitude of displacement of the body is proportional to a change in output of the light-receiving element (15) since, irrespective of where the displacement of the body begins from, a constant width of the region is maintained along a direction perpendicular with respect to the direction of the relative displacement. In other words, the displacement of the body can be accurately detected since linearity is achieved between the two.

Date Jun. 27, 1991.Surface-coated components, such as contact pieces for vacuum switches, are produced by means of the method by melting open the surface of a metallic substrate (1) in a local area (15) by an energy flow (12) and combining an additive (8) with the melted-open material of the local area (15). It is intended to produce components with large areas with small outlay in apparatus by means of this method. This is attained by the following steps: Prior to melting open the local area (15), the substrate (1) is pre-heated to a temperature considerably above room temperature, but below its melting temperature. After pre-heating, the local area (15) on the surface of the substrate is melted open and the additive (8) is applied to the substrate surface in the form of a loose powder layer (10). The local area (15) melted open by the energy flow (12) is guided to and through the powder layer (10) and in the course of this powder present in the powder layer (10) is wetted or the powder layer (10) is soaked with liquid material from the melted-open local area (15), because of which the powder of the powder layer (10) is bonded with the surface of the substrate (1) and the desired surface layer (16) is formed.

Abstract: Un système de traitement d'une topographie binaire de signaux de données d'éléments d'image représentatifs d'un réseau multidimensionnel de données d'imagerie (par exemple un texte alpha-numérique) pour la transmission par un canal de communication de facsimilé permet de comprimer des données d'imagerie à l'aide de plusieurs unités de compression de données, dont une unité respective est capable de comprimer des données qui sont envoyées à une vitesse de compression qui n'est qu'une fraction de la vitesse des données. La topographie binaire est sous-échantillonnée en la démultiplexant en sous-réseaux de données. Les données des sous-réseaux sont couplées sur des ensembles respectifs des unités de compression qui exécutent une compression parallèle et bi-dimensionnelle des données des sous-réseaux démultiplexées. Même si les sous-échantillons de données associés aux rangées successives de la topographie binaire ne sont pas consécutifs, et que par conséquent ils peuvent contribuer à une réduction de l'opération de compression dans le sens horizontal compte tenu du fait que les données sont du texte, des échantillons de données successifs à l'intérieur de chaque colonne d'un sous-réseau sont en corrélation inhérente à un degré plus élevé entre eux que les valeurs de données que l'on rencontre à l'intérieur des rangées respectives de l'acquisition des bits d'origine. En conséquence, l'opération de compression de données bidimensionnelles executée par chaque unité ne souffre d'aucune baisse de qualité du signal de sortie.
