Abstract: The invention provides a device for distributing electric potentials for supplying a component with electric power, capable of being incorporated in the case in which the component is encapsulated.This device is in the form of a plate comprising conducting planes connected to external power supply potentials. This plate either forms the cover of the case or is placed inside the case above said component. Each of the conducting planes of the device is connected, outside the case, to the power supply potential and, inside the case, at multiple points to the component so as to distribute these potentials to the appropriate inputs/outputs thereof, thus reducing the number of inputs/outputs of the case.

Abstract: An oven is provided for baking a substrate having a printed circuit obtained by depositing on an insulating substrate, by silk screen printing, an insulating or resistive ink comprising an organic material which forms a temporary binder of this ink, which oven is provided with gas injection means for baking in the desired atmosphere, means for extracting the reducing gases and/or baking residues obtained by transformation of the organic materials under the effect of the temperature, and means for sweeping these reducing gases in the direction of the extraction means so as to accelerate removal thereof without creating any zone of stagnation or turbulent flow.

Abstract: A device is provided for regulating a combustion engine whose operation is governed by a set of parameters P.sub.i (1.ltoreq.i.ltoreq.n), including essentially an assembly of "m" regulation loops for regulating "m" parameters (with m.ltoreq.n), a set of "q" sensors (with q=n-m) for measuring the parameters which are possibly not regulated and a regulator common to the assembly of these "m" loops, for providing, from the different references and the values detected by the different sensors, a signal controlling the different actuators so as to ensure the evolution of each of the regulated parameters, in connection with the evolution of all or part of the other parameters, regulatable or not, regulated or not and for maintaining the engine at all times in a condition of optimum operation.

Abstract: An electronic box having a capacitor in the form of a supporting plate bearing a component and covered by a cap. Additionally, the box includes a capacitor connected onto the supporting plate in such a way as to be situated between the component and the cap.

Abstract: A casing for protecting electronic components or circuits against ionizing radiations, comprising an alternance of layers of materials having low and high atomic charge numbers, forming a multi-layer capacitor, and a base comprising an alternation of the same type.

Abstract: A hermetically sealed encapsulation package for electronic components and integrated or hybrid electronic circuits has a base on which the component or circuit is mounted in the conventional manner and a cover. In one embodiment, the base includes a layer of a material which is able to retain any water molecules which might remain within the package after sealing or which may result from in-leakage from the surrounding atmosphere.

Abstract: The mean value of a continuous function controlled by a constant-period all-or-none signal is regulated and stabilized by controlling the maximum value of the continuous function in dependence on a sawtooth signal having a variable period, each leading edge of the sawtooth signal being in synchronism with the peaks of the regulated signal.

Abstract: A flat, elongate workpiece such as a knitting-machine needle, stamped from sheet metal with a transverse lug whose narrow faces require precise machining, is clamped in a workpiece holder with its lug centered on an axis about which the workpiece holder and an associated tool mounting are relatively rotatable. The tool mounting includes two symmetrically positioned supports, carrying respective power-driven shaping tools such as grinding wheels or millers, which are limitedly movable in a plane including the axis and are interconnected by a tension spring drawing them toward each other. An interposed cam disk, engaged by rollers mounted on these supports, determines the extent to which the two shaping tools can approach the axis in machining respective lug faces during a relative rotation of up to 180.degree..

Abstract: A writing head overlying a recording medium, in the form of a sheet with edges respectively extending in mutually orthogonal directions X and Y, carries a linear array of equispaced electrodes extending in the X direction over a fraction of the width of the sheet. The writing head is displaceable in the Y direction along a supporting bar which in turn may be moved in the X direction. A control unit commands the selective energization of these electrodes to record a dot pattern as the writing head moves in the Y direction to sweep a column of dot positions, the column being wide enough to accommodate several alphanumerical characters and/or graphic symbols read out on a line-by-line basis from a plurality of memory sections. With at least one additional linear electrode array on the writing head, generally transverse to the X direction, heavy lines or curves may be traced on the recording medium.
