  • Patent number: 5657412
    Abstract: A fibre-optic splice case has a support for a sealed box which contains a splice connection strip that connects together the ends of two optical fibres from two separate cables. The box is a sealed assembly having a centre of symmetry. The two cables are connectable to the box. The box has a cylindrical support with a central drum and a coaxial outer wall defines therebetween a housing in which the two cables are unreeled or reeled-up in order to deliver or take up a length of cable sufficient to allow the splice to be made. The box also has two separate straight sides each lying substantially in an extension of the other. The straight sides tubular passages are provided for fixing the ends of the two cables. The ends of these straight sides are joined with bottoms of circular overall shape, giving the box a cross-section in the form of a snail-shell.

  • Patent number: 5618229
    Abstract: The machine of the invention comprises downstream a squeezing device defining portions (P), successive pairs of first and second plates (1), 1') disposed parallel inside which the portions (P) are engaged. The first and second plates (1, 1') of each pair move forward in the machine by keeping their spacing and remaining longitudinally in coincidence, whilst moving transversally at the same speed but in opposite directions so as to make the portion (P) they enclose rotate. Secondly, the transversal movement directions are alternate between the first successive plates (1) and between the successive second plates (1'). Consequently, the continuous filled-up casing (B) driven by the pairs (1, 1') advances inside the machine in the form of successive portions (P) between which a twist is formed.

  • Patent number: 5570313
    Abstract: The invention concerns a memory cell insensitive to disturbances. The memory cell, that contains information in the form of two complementary logical levels (X, C(X)), each logical level being stored in a node of the cell (N1, N2), is characterized in that it comprises means of storing the same logical level in two different nodes (N1, N2, N3, N4), the said means being able to restore any logical level to its initial state preceding a modification made on it due to a disturbance, as a result of holding the value of one of the two logical levels complementary to the logical level that was modified.

  • Patent number: 5544111
    Abstract: Process for programming memories of the fuse protection type, particularly those used in smart or chip cards. A breakdown voltage is applied (204) for a time greatly exceeding that used in the prior art, and with a current at a value well above that used in the prior art. Typically 100 ms and 2A are used. Programmable processors (102) make it possible to regulate these values and carry out tests beforehand. These methods avoid reconstitution of blown fuses and the errors resulting therefrom.

  • Patent number: 5542081
    Abstract: An integrated circuit, for use in a microprocessor-based chip card that provides several different functions at different hierarchical levels. The circuit has a microprocessor, a read-only memory managing a protection system and an EEPROM capable of containing not only data but also a code that can,be executed by the microprocessor. Different programs are placed in the EEPROM memory zones (Z1C, Z2C, Z3C). The read-only memory contains filtering instructions used to read a filter address in a specified zone Z1B, Z2B, Z3B of the EEPROM. Depending on the contents of this zone, the program will be routed, or not routed, towards the zones (Z1C, Z2C, Z3C). Thus information is recorded at only one address of the EEPROM in order to control accessibility to the different functions of the circuit.

  • Patent number: 5530404
    Abstract: A variable gain amplifier which has n parallel-connected elementary amplifiers, and components for selecting j-order (j=1, 2, . . . , n) elementary amplifier according to the desired gain. Each elementary amplifier is of a common base type. The variable gain amplifier includes components that are used to obtain a low value input impedance that is independent of the gain of the selected elementary amplifier. The variable gain amplifier will find particular application at the input stages of amplification lines of receiving circuits which require noise performance characteristics.

  • Patent number: 5526063
    Abstract: A three-color image projector, of the type using several colored light beams with primary colors, with improved luminous efficiency. The projector employs spatial rather than temporal beam modulation. The projector includes a generator producing light in the three spectral bands corresponding to the primary colors (red, green, blue). The generator has at least two light sources (S1, S2), one of which produces multi-spectral band light, and the other is a monochromatic source. By comparison with the prior art, where the white light is produced by a single source, this arrangement avoids, in particular, the elimination of a significant quantity of lumens in the excess primary color.

  • Patent number: 5526230
    Abstract: A device and method for interconnection packages in a stack. Each package encapsulates, for example a semiconductor chip containing an integrated circuit, which for example may be a memory. The packages (2) which have connecting pins (21) are mounted on support grid (4) which preferably act as a heat shunt, and are stacked and linked to each other with a resin coating (5). A stack (3) is cut out so that the pins on the packages and one edge of the grids are flush with faces (31, 32) of the stack (3). Connections between the packages themselves, and between the packages and stack connecting pads, are made on the faces of the stack. The connecting pads are where necessary fitted with connecting pins.
