Abstract: An optical device, similar to binoculars, which includes, between the objective lens and the eyepiece a miniature screen displaying an image controlled by a computer, and an optical reflex device capable of superimposing the screen image on the image seen through the objective lens. The device also includes, selectively or cumulatively, a variable light attenuator and a light amplifier for night vision. The device can be used, in conjunction with a computer, to add further information on geographic positions, friends, enemies, infrared images, etc. into the scene seen through the binoculars.

Abstract: Bioparyl is obtainable by a disclosed extraction hydrolysis and purification procedure applied to golden autumn leaves of the Gingko biloba tree. Bioparyl plays an important role in the regulation of the activity of certain enzymes, particularly ribonucleases (RNases), implicated in the fundamental mechanism of gene expression. It is low in or free from toxic or side effects in healthy animals, and can be used to ameliorate several pathogenic conditions. Bioparyl is effective in preventing or reversing fibrosis in various tissues, including the lungs and skin, engendered by radiation or chemotherapy. It reduces abnormally high concentrations of gamma-globulins and immuno-globulins found in certain inflammatory or auto-immune diseases, including Acquired Immune Deficiency Syndrome disease (AIDS). In patients with leukemia or solid cancers, Bioparyl normalizes the activity of ribonucleases.

Abstract: In a method for the electrical testing of equipotential lines, each line containing at least two testing points wherein, at least one cut-off line separates the testing points. The testing points of a first side of the cut-off line are grouped together in a first set and the testing points of the other side are grouped together in a second set, the testing points of the cut-off line belonging to both sets. The electrical test is carried out, in a first step, between the testing points of the first set and, in a second step, between the testing points of the second set, testing points of the first set being grouped in the second set while, in the same time, remaining in the first set, to ensure the continuity of the electrical testing between the testing points of the two sets. Application to tests on electrical continuity or insulation of electrical boxes notably.

Abstract: Disclosed is a device for access to and follower control of a track of an optical disk. This device has an optical head with an axis orthogonal to the plane of the disk, at least one fixed magnetic circuit comprising a core that is secant with all the turns of the track, the gap of which forms a plane that is substantially perpendicular to the support, a first motor device allowing for the access to and radial tracking of the track formed by at least one first coil mounted so that it moves on the core of the magnetic circuit and a second motor device that enables the focusing of the radiation on the track consisting of a second coil cooperating with a magnetic circuit. The optical head, the coil of the first motor device and the coil of the second motor device are rigidly fixed to one another so as to form a single compact moving element that moves in the gaps of the magnetic circuits. The disclosed device can be applied to digital optical disks.

Abstract: A method for the manufacture of integrated circuits where it is desired to produce narrow conducting grids separated by a narrow gap and uses the lifting-up of silicon nitride (bird's bill) which is formed during a thick localized oxidation. A localized oxidation step is carried out and the oxide formed is totally removed. The edges (20, 22) of a nitride layer (14) stay overhanging. A conforming polycrystalline-silicon deposition enables silicon to be deposited uniformly, including beneath these edges. Finally, vertical anisotropic etching removes the silicon everywhere except beneath the overhanging edges, so that two silicon lines (28, 30) remain. An ion implantation (34) may be performed between the two lines. The method will find particular application for making anti-dazzle systems for photosensitive charge-coupled devices.

Abstract: Disclosed is a 3D encapsulation of semiconductor chips, each chip containing for example an integrated circuit, this encapsulation being aimed at optimising heat dissipation by conduction. Connection means are associated with each chip, making it possible to extend the pads of chips towards three sides of the chip, thus leaving the fourth side free. The chips are stacked on one another and then can be connected to heat dissipation means by their fourth side.

Abstract: The MOS cell with adjustable threshold voltage is a cell of the type with a memory that is electrically-erasable and programmable by storage of charges by tunnel effect in a floating gate. To obtain a circuit with adjustable threshold voltage, the cell is first of all "programmed" at zero so that all the charges that may be stored are removed and then it is "erased", with its source grounded, its drain taken to the high potential and its control gate taken to the potential desired for the threshold voltage V.sub.T of the circuit. At the end of this phase, the threshold voltage is adjusted. This device can be applied notably to circuits requiring precise voltage references in MOS technology, namely circuits of the detector or analog-digital converter type.

Abstract: The invention relates to exchangeable memory cards having several integrated circuits for personal computers. These memory cards serve as a large capacity mass memory for replacing floppy disks and other exchangeable magnetic supports. In particular, they have a plug-in connector (12) at the end of the card and can be inserted in the reader in accordance with PCMCIA standards of a micro-computer. According to an aspect of the invention, a flush contact chip card memory is formed by such a plug-in card (10) and for this purpose the latter has a supplementary connector with flush contacts on its principal face (14). The thus formed reader is transportable, with its application software stored in the card (10) and can be installed in any random microcomputer equipped with a PCMCIA reader. A credit card or security card (18) can then be inserted in the transportable reader. The memory card is typical a PCMCIA size card with a recess on one major plane surface and the security card fits into this recess.

Abstract: The invention is applicable to matrix detector or display screens formed by assembling several elementary screens. A matrix screen according to the invention comprises several elementary screens (E1 to E4) spliced together on one of their edges (10, 11). According to the invention, each elementary screen (E1 to E4) includes a mechanical stop device (B1 to B4) which mates with a mechanical stop device on an elementary screen to which it is spliced so that the two elementary screens are positioned relative to each other. This arrangement avoids long and difficult alignment and indexing during the assembly of the elementary screens (E1 to E4) since these operations are completed when the elementary screens are cut, this operation itself requiring the use of accurate alignment and indexing tools.
