Title: Nameplate clip for fitting on clothing
Inventor: ARVISENET JACQUES
IPC: G09F3/20
Filed: 1996-11-08
Abstract: The clip consists of two parts. One part (1) consists of a longitudinal guide (7) and a retention bearing (16). The other part (14) is in the form of a lever of which the central part consists of a slider (13) which is engaged and slides in the guide (7). One if its ends acts as the jaw of the clip, while the other end is extended by an incurved elastic part (18) bending towards the central part and having at its end a pivoting piece (20,21) which cooperates with the retention bearing (16) to enable an articulation between the two arms (1,14). The dimensions of the elastic part (18) is such that the two parts (1,14) clip together on rest when pressure is applied to the elastic part (18) and are opened when the pressure is reversed which deforms the elastic part (18) and causes a guided movement of the slider (13) in the guide (7).

Title: Electrically operated parking brake on motor vehicle
Inventor: BRETON RAYMOND
IPC: B60T13/74
Filed: 1997-04-18
Abstract: The electrically operated parking brake has a block (1) that moves along slides (2). An endless screw (4) is driven by an electric motor to apply traction on the arm of the brake lever (5). While the brake linings do not touch the braking surface the force on the brake cable (3) is low. A spring (6) stops the arm of the lever from pivoting and the sliding block (1) moves rapidly. As soon as the brake linings make contact with the braking surface, the force on the cable increases sharply, causing interaction of the teeth (7) at the end of the lever and a rack (8) cut in the side of the slide to apply greater force to the sliding block.

Filed: 1997-06-05
Abstract: The invention concerns a device for implementing a blow moulding method providing a better distribution of operating power, comprising several modules (11, 12, 13) connected by a continuously driven conveyor belt (14). Each module comprises a furnace (17) heating preforms, a transfer wheel (18), means (19) transferring preforms from the conveyor belt onto the transfer wheel, a press (20) moulding objects from the preforms and a member unloading (21) the moulded objects. Preforms are brought in the proximity of all the modules by means of the conveyor belt, then two preforms are brought on each transfer wheel module. In order to stagger the high power-consuming steps, such as opening the press and blowing the objects from the heated preforms, the method consists in modifying the travel distance between the preform loading point and the transfer means and/or between the transfer means and the press opening point or both distances from one of the modules to the other simultaneously.

Title: Dispositif semiconducteur a transfert de charges
Inventor: CARANHAC SOPHIE
IPC: H01L29/768
Filed: 1997-11-14
Abstract: L'invention concerne les dispositifs à transfert de charges constitués sous forme de registres à décalage, et plus précisément ceux qui fonctionnent selon le mode MPP (Multi-Pinned Phase), c'est-à-dire avec polarisation négative forte des électrodes pendant les phases d'attente ou d'intégration de charges photosensibles. Ces registres utilisent une barrière de potentiel créée par une implantation de compensation P dans une zone 16 située sous une première électrode de chaque étage du registre. Cette barrière sépare les étages les uns des autres.Pour augmenter la capacité de stockage de charges pendant la phase d'intégration et la capacité de transfert de charges pendant le transfert, on prévoit que l'implantation de compensation de la zone 16 s'étend sous une partie seulement (et non sous la totalité) de la première électrode de chaque étage du registre.Application aux capteurs d'image photosensibles, aux lignes à retard analogiques, aux mémoires analogiques à transfert de charges, fonctionnant en mode MPP pendant les phases d'attente pour limiter les pertes d'informations dues au courant d'obscurité.

Title: Optical wavelength multiplexed transmission system using transponders
Inventor: WATANABE SEIJI
IPC: H04B10/29
Filed: 1997-11-27
Abstract: The data transmission system uses multiplexed optical wavelengths with repeaters.  The system includes an optical transmitting unit sending the multiplexed optical signals, a transmission line including a number of optical amplifiers, and an optical receiving unit for the multiplexed optical signals.  An optical filter is provided to equalise the signal-to-noise ratios (S/B) such that the loss characteristics are adjusted, making the signal-to-noise ratios the same for all multiplexed wavelengths.  The adjustment furthermore ensures that the power levels of all the sources used are practically the same when received at the receiver.  The optical filtering may be provided by an Etaron filter, or may be provided by a network of optical fibres.  This may provide compensation for variations in the signal-to-noise ratios of between -40% and -60%.
