Abstract: L'invention a pour objet un dispositif de démodulation d'une onde modulée en phase, de type DPSK par exemple, applicable à un système MLS. Il comporte un oscillateur local (1) dont la phase est modulée (2). Le signal ainsi modulé est mélangé au signal incident s(t). Le signal issu du mélangeur (5) est appliqué à une boucle (3) dont le signal de sortie commande le modulateur de phase (2) et constitue le signal de sortie du dispositif (Ss). ABSTRACT The invention concerns a demodulator for a phase-modulated wave, for example of the DPSK type, applicable to an MLS system. The demodulator comprises a local oscillator (1) the phase of which is modulated (2). The signal so modified is mixed with the incident signal to be demodulated s(t). The signal emitted by the mixer (5) is applied to a loop (3) the output signal of which controls the phase modulator (2) and constitutes the output signal (Ss) the device.

Abstract: A dye-containing polarizing film is disclosed. It contains a disazo dye represented by general formula (I), wherein Me represents a transition metal atom such as copper, nickel, zinc or iron, r represents a 1- or 2-naphthol residue which is bound to the azo group at a position adjacent to the hydroxy group forming a complex bond with the transition metal and which may be substituted by a sulfo group, a sulfonamido group, an animo group, an acylamino group, an allylamino group, or a hydroxy group not adjacent to the azo group, X and Y each represents a hyd-ogen atom, a C 1 -C 4  alkyl group, a lower alkoxy group, a carboxyl group, a sulfo group, a sulfonamido group, a sulfonal- kylamido group, an amino group, an acylamino group, a halogen or a nitro group, and Z represents a hydrogen atom, a C 1 -C 4  alkyl group or a lower alkoxy group, provided that formula (I) contains 1 to 3 sulfo groups. The film shows a higher durability than conventional dye-containing polarizing films and has nearly the same excellent polarizing performance as an iodine-containing polarizing film, thus being effectively utilized for optical uses including liquid crystal displays and CRT filters.

Abstract: In the case of a conventional grab, e.g. of a crane, there is the risk, when working in a scrap bunker, of this grab striking the wall of the scrap bunker and damaging the concrete in the process. In order to provide a remedy here, it is proposed according to the invention that the grab (8) be provided on the outside with elastic cushions (12, 14) or flexible linings (30) at the points where it could strike the wall. In this way, the impact energy can be absorbed. The hitherto conventional expensive lining with a wooden casing is thus dispensed with. The cushions (12, 14) and linings (30) can easily be exchanged when required without the operation of the scrap-handling plant having to be interrupted. <IMAGE>

Abstract: The anti-skid valve is provided in the vicinity of its inlet connection 1 on the brake pressure-source side with a restrictor 5 limiting its cross-section of flow. Downstream of the restrictor 5 are a shut-off valve 8 and an air-relief valve 13 and an outlet connection 2; the shut-off valve 8 and the air-relief valve 13 can each be switched by a diaphragm member 7 and 12 respectively, which can be stressed in the closing direction by switching pressures controlled by pilot valves 10. The pilot valves 10 are supplied with compressed air via a compressed-air supply passage 17 from an inlet space 4 situated between the inlet connection 1 and the restrictor 5, preferably between a screen 3 and the restrictor 5. By means of this compressed-air supply to the pilot valves 10, it is guaranteed that, in the event of pressure irruptions into spaces of the anti-skid valve which are downstream of the restrictor 5, the pilot valves 10 are nevertheless constantly supplied with a sufficiently high pressure level, with the result that their switching pressures are always capable of reliably switching the shut-off valve 8 and the air-relief valve 13 into their sealed closing position even in the case of stiffness or sluggishness of the diaphragm members 7 and 12 due to the temperature. <IMAGE>

Abstract: A high density, mixed technology integrated circuit com­prises CMOS structures and bipolar lateral transistors, the electrical efficiency and Early voltage of which are main­tained high by forming "well" regions through the collector area. The operation determines the formation of a "collec­tor extension region" extending relatively deep within the epitaxial layer so as to intercept the emitter current and gather it to the collector, subtracting it from dispersion toward the substrate through the adjacent isolation junc­tions surrounding the region of the lateral bipolar tran­sistor. Under comparable conditions, the ratio between Ic/Isubstrate is incremented from about 8 to about 300 and the Early voltage from about 20 V to about 100 V. The V CEO , BV CBO  and BV CES  voltages are also advantageously increased by the presence of said "well" region formed in the collec­tor zone.

IPC: B62M11/18
Filed: 1989-05-02
Abstract: Un moyeu (15) de changement automatique de vitesses à cinq paliers, sensible au couple, utilise des embrayages (42) à ressort enroulé interne qui font tourner plusieurs cylindres (22) coaxiaux à l'exception du cylindre se trouvant à une extrémité de l'axe mis en rotation par une dent de pignon à chaîne. Une commande par engrenage (48) est interposée entre les cylindres pour les faire tourner à des vitesses de rotation progressivement différentes. Le moyeu de roue est mis en rotation par les ressorts (16, 17, 18, 19) enroulés extérieurs, un sur chaque cylindre, une extrémité étant fixée au moyeu et l'autre extrémité étant flottante. Les embrayages à ressorts enroulés internes sont actionnés par des ressorts de compression (39) entre les cylindres (21), et s'allongent pour actionner l'embrayage associé et se compriment pour désactiver l'embrayage. Les ressorts de compression ont une résistance progressivement différente le long de l'axe des cylindres. Lorsque le couple appliqué est égal à la force d'un ressort de compression entre deux cylindres, le ressort de compression s'allonge pour activer l'embrayage associé et faire tourner le cylindre associé.
