Abstract: An ECL circuit is designed such that at the beginning of the falling of the output level, the current flowing to an output terminal (11) is rapidly led in the direction where it will be reduced, the potential of the output terminal (11) at this time is directly detected, and a pull down transistor (15) is controlled through a feedback loop, thus assuring high-speed operation and low power consumption. A control circuit is provided to regulate the collector current of the pull down transistor (15), which is used to drop the level of the potential at the output terminal (11). This control circuit is so designed that the base current of the pull down transistor (15) is controlled by the operation of another, single transistor (12), and no capacitor which will obstruct the circuit integration is employed to drive the pull down transistor (15). The structure of this circuit is therefore advantageous in realizing higher integration.

Abstract: Lawn mower (10) height-adjust systems include three embodiments. Two permit the user to adjust the position of the deck (12) relative to each wheel (18) individually. The third permits the user to adjust the positions of all four wheels (18) simultaneously, aided by a counterbalance system. A modification of the third embodiment is available to automatically bypass the height-adjust mechanism in the event an abnormally high load is placed on the deck (12). One of the two individual systems (16) permits an operator to adjust the position of a respective wheel (18) simply by removing a single nut (82) and washer (80) from an axle bolt (78). The second individual height-adjust system permits the operator to adjust the height of an individual wheel (18) by using one hand, and without having to disassemble the mechanism. The system which adjusts all four wheels (18) simultaneously links front and rear axle subassemblies with a connecting rod (306), and indexes all four wheels (18) simultaneously through a release handle (324) which is recessed in a cavity formed in the lawn mower deck (12). When the operator lifts the release handle (324), he or she may simultaneously grasp a portion of the deck (12) with the same hand and easily raise or lower it to a desired position. A single unitary plastic deck (12) is the foundation for each of the three height-adjust systems, thereby significantly reducing the cost otherwise incurred by manufacturing three separate types of lawn mowers.

Abstract: The collapsible clothes-drying rack according to the invention is characterised in that it has two legs 1, 2 which are hinged in joints 12, 13 and in which two tiltable hanging grids 3, 4 for the clothes are fixed. Each grid 3, 4 is fixed rotatably at a pivot point 8, 9 of the legs 1, 2 and is guided through a guide and locking hook 6, 7 interacting with a lock 8, 9 of the legs 1, 2. It is achieved by the specific design of the joints and of the locks that the rack can be opened and closed by a single movement and is folded up in itself, or the grids 3, 4 are opened, which automatically brings about the opening or the closing of the legs 1, 2. Furthermore, compared to other known racks, the rack has the advantage of a low number of joints, which makes it less complicated and less expensive. <IMAGE>

Abstract: On décrit un système de transport à tapis roulants rapides, en particulier pour les systèmes de transport urbains, et qui comprend une ou plusieurs plate-formes ou disques (2), de diamètres appropriés, qui tournent autour d'un axe vertical. Un tapis auxiliaire (6) ou principal (1) à éléments raccordés passe autour de la plate-forme ou du disque (2). Lorsque l'utilisateur passe du tapis à la périphérie de la plate-forme ou du disque (2) et se rapproche de son axe de rotation, sa vitesse linéaire est réduite par ledit mouvement. Un mouvement dans le sens inverse, depuis l'axe de rotation de la plate-forme ou du disque (2) entraîne une augmentation de la vitesse linéaire de l'utilisateur. L'utilisation de différents niveaux de transport par tapis au moyen d'une série de dispositifs tels que des ascenseurs et des escaliers, ainsi que l'utilisation de tapis et de plate-formes en série, permet d'obtenir n'importe quelles augmentations et réductions de vitesse, et on peut envisager des tapis qui se déplacent à n'importe quelle vitesse.

Abstract: Les technologies de stockage en mémoire comprennent des mémoires vives et des dispositifs à couplage de charge. La fonction mémoire adaptative et la fonction servomémoire améliorent les caractéristiques de mémoire. Dans un mode de réalisation de mémoire vive, on utilise un détecteur (220B, 220A) afin de détecter un état d'adresse en mémoire (217) et afin de commander la mémoire (222) ainsi que le registre d'adresses en mémoire (218) en réponse audit état. Dans un mode de réalisation de dispositif à couplage de charge, on utilise un détecteur (220A, 220B) afin de détecter un signal de référence de mémoire (217) et afin de régénérer les signaux mémoire (221A, 221B, 221) en réponse à ce dernier. La régénération, les performances et la capacité améliorées de la mémoire améliorent les caractéristiques du système. Une architecture de mémoire améliorée offre les avantages d'une vitesse accrue, d'un coût inférieur et d'une efficacité de mise en oeuvre. Les informations stockées en mémoire peuvent être parcourues et extraites à une vitesse supérieure à la vitesse d'adressage associée aux mémoires. Cet agencement permet un fonctionnement à vitesse supérieure avec des mémoires de coût inférieur. L'emploi d'un tampon de sortie tel qu'un système premier entré premier sorti (FIFO), permet la normalisation de fréquences de base de mémoire.
