Title: Reduced-capacitance electron gun for a cathode ray tube
Inventor: HENRI DOYEUX
IPC: H01J29/82
Filed: 1989-09-29
Abstract: The invention relates to an electron gun for a cathode ray tube, and it relates more particularly to means which make it possible to integrate the electron gun to a connector base of the tube in a novel way, so as to reduce the capacitance which a control electrode of this electron gun exhibits. The electron gun (25) includes a control electrode (28) followed by a first acceleration electrode (29), these two electrodes being linked mechanically and rigidly by insulating bars (35,36,37). The electron gun further includes a collar (40), and, according to one characteristic of the invention, the insulating bars (35,36,37) are fixed directly to the collar (40), which collar is in its turn fixed to the connector base (27). As the control electrode (28) is not electrically linked to any other element, its stray capacitance is reduced.

Title: Dispositif de freinage anti-blocage pour vehicule
Inventor: ATKINS THOMAS M
IPC: B60T8/66
Filed: 1989-11-06
Abstract: L'invention concerne un dispositif 10 de commande anti-blocage des freins d'un véhicule, ne nécessitant pas une pompe hydraulique auxiliaire, et dans un mode de réalisation préféré, ne commande que les freins arrière d'un véhicule à quatre roues. Le dispositif comprend une soupape d'isolement 22 normalement ouverte entre le maître-cylindre 14 et les freins arrière, et une soupape de vidage 26 normalement fermée entre les freins arrière et un accumulateur de fluide 27. Une commande informatique 30 surveille la vitesse des roues arrière et de leur décélération, et lors du freinage du véhicule, commande l'application de la pression hydraulique aux freins arrière via les soupapes d'isolement et de vidage de manière à corriger les écarts de la vitesse des roues et éviter le blocage des freins. La commande informatique détecte un changement du revêtement lorsque celui-ci passe d'un faible coefficient de frottement à un coefficient de frottement élevé se produisant lors d'un écart de la vitesse des roues, et applique ensuite une pression supplémentaire aux freins par ouverture sélective de la soupape d'isolement. En outre, la commande détecte le moment où l'une des roues arrière reste bloquée après la prise des mesures anti-blocage. Dans ces cas, les paramètres de fonctionnement standard commandant la réapplication de la pression supplémentaire sont modifiés.

Title: Electronic lock for integrated circuit, with double floating-gate transistor
Inventor: FRANCK EDME
IPC: G11C16/22
Filed: 1989-12-15
Abstract: The invention relates to integrated circuits, and more particularly a way to make an electronic fuse in an integrated circuit; electronic fuse is understood to mean an element which enables the configuration of the circuit to be changed in a manner which is in principle irreversible. According to the invention, the fuse comprises two electrically programmable and electrically erasable memory cells (TGF1, T1, SA1; TGF2, T2, SA2) whose outputs are combined in an exclusive-OR logic gate (10), the fuse being operated by programming one of the cells (TGF1) and erasing the other (TGF2). At the start, the state of charge of the floating gates of the two cells is not well known, but the states are identical and the exclusive-OR logic gate delivers a zero. Then, on programming one cell and erasing the other, the state of the logic gate 10 is forced to 1. The first cell is in principle non-erasable, and the second non-programmable.
