Abstract: Dans la station de fixage d'une imprimante ou d'un copieur électrophotographiques sont disposés un cylindre de fixage (11) chauffé par un module radiateur (30), et un cylindre de pression qui pivote en direction et à l'opposé du cylindre de fixage (11) par l'intermédiaire d'un mécanisme à cames (8, 7). Afin que le cylindre de fixage et le cylindre de pression puissent être remplacés tout en étant encore chauds, le cylindre de fixage (11) est monté dans des brides de palier (14, 16), dont l'une (16) est fixée à demeure dans l'appareil tandis que l'autre (14) est montée amovible. La bride amovible (14) comporte des éléments de serrage (26) qui maintiennent le cylindre de fixage, ainsi qu'une poignée au moyen de laquelle la bride (14), avec le cylindre de fixage (11) qui y est rattaché, peut être enlevée de la station de fixage. Le cylindre de pression (9) est monté amovible entre deux coulisses (8) par l'intermédiaire d'un boulon de fixation amovible (57). Un dégagement de refroidissement (40, 51) destiné à recevoir le cylindre de fixage (11) chaud et le module radiateur (30) est également ménagé dans l'appareil.

Abstract: PCT No. PCT/SE90/00860 Sec. 371 Date Jun. 22, 1992 Sec. 102(e) Date Jun. 22, 1992 PCT Filed Dec. 20, 1990 PCT Pub. No. WO91/09581 PCT Pub. Date Jul. 11, 1991.The present invention relates to a resilient body which includes two thin layers (1, 6) of flexible material to which intermediate elastic threads (2, 3, 5) or bands are fastened in a stretched state and disposed in a regular, net-like pattern, and bodies (4) of soft material are disposed between the two layers (1, 6) in at least some of the meshes of the net formed by the elastic threads. These bodies have smaller dimensions than the meshes, so as to permit total or partial contraction of the stretched or tensioned elastic threads. The bodies also have an intrinsic stiffness such as to substantially retain their shape upon contraction of the elastic threads. The invention also relates to a method for manufacturing the inventive resilient body.

Abstract: Un circuit de commande d'un moteur pas-à-pas (20) comprend un circuit d'attaque transistorisé (122) comportant une pluralité de positions de commutation, dans chacune desquelles le circuit d'attaque (122) est agencé pour fournir du courant à des enroulements choisis du moteur pas-à-pas dans des directions sélectionnées. Un séquenceur (130) est agencé pour appliquer des signaux de commande au circuit d'attaque (122) de manière à changer de manière séquentielle les positions de commutation. Un encodeur (128) génère un train d'impulsions qui représente la vitesse et la position du moteur (120). Un contrôleur d'excitations (134) est agencé pour recevoir les impulsions de l'encodeur et pour générer, en réponse, des signaux de changement d'excitation pour effectuer le changement des positions de commutation, et des signaux de changement de direction pour déterminer la direction dans laquelle la séquence des positions de commutation est changée. La possibilité d'engendrer à la fois des signaux de changement d'excitation et des signaux de direction permet de disposer d'une souplesse maximale, car elle permet par exemple le renversemenet rapide du couple du moteur pas-à-pas (120) en imprimant au séquenceur (130) un mouvement pas-à-pas en arrière à travers la séquence de commutation. Les signaux de changement d'excitation sont générés par ledit contrôleur d'excitations (134) d'une manière qui permet de varier l'angle de commutation du moteur pas-à-pas sensiblement sans limitation, de manière à offrir à l'utilisateur une commande totale du moteur pas-à-pas.

Title: Vanne rotative de nettoyage rapide
Inventor: WILSON LARRY JAMES
IPC: G01F11/24
Filed: 1991-04-09
Abstract: Vanne rotative, et procédé de nettoyage apparenté, comprenant un logement généralement cylindrique (104) avec un axe central, et un arbre rotatif (106) monté sur une première plaque terminale (130) du logement pour assurer la rotation par un système d'entraînement (108) adjacent à la première plaque terminale. Un rotor à palettes (102) est connecté à l'arbre dans une position de fonctionnement entièrement à l'intérieur du logement pour transmettre la rotation de l'arbre autour de l'axe aux palettes (140) du rotor. Le rotor peut être déplacé axialement et sélectivement par rapport à l'arbre, pour être mis en position de nettoyage entièrement en dehors du logement. Cette opération est facilitée par le montage du rotor sur l'autre, la deuxième, plaque terminale (110), car, en enlevant la deuxième plaque terminale du logement et en l'éloignant, dans le sens axial de la première plaque terminale, on déplace aussi le rotor. Ainsi, l'arbre n'est jamais détaché du système d'entraînement et, par conséquent, les positions radiales et longitudinales de l'arbre par rapport à l'axe ne sont pas modifiées pendant le démontage et le remontage.

Abstract: Prior art current-mirror circuits are not particularly well designed for generating very low currents in the nA range. It is indeed possible to use multiple current reflection with the aid of multiple emitters to generate such currents but the currents thus obtained depend upon parameter tolerances and temperatures. In addition, such circuits require a fairly large chip area. The relationship between the reference current (Iref) of the current-mirror circuit and the first output current (Iout) at the collector of the output transistor can be set via the dimensions of a first resistor R in the emitter of the output transistor (34) of a current-mirror circuit. By adding a second current-mirror stage (38) with a second resistor R' therein and a second output current (Iout'), it is possible to obtain for R = R' the relationship between the first and second output currents corresponding to the ratio between the reference and the first output current.

Abstract: In the case of three-phase networks (A, B) which are to be coupled to one another, there is often a requirement to maintain or set a specific phase shift between the voltages of the three-phase networks (A, B). To this end, a device (1a, 1b, 1c, 1d) is proposed which comprises two groups of transformer windings (6u to 6t), each winding (6u to 6t) being connected via in each case one switchable stepped winding (8u to 8t) to the star point (10a, 10b) of the respective group. The stepped windings (8u to 8t) are in this case interchanged cyclically in phase and can be switched over cyclically. <IMAGE>

Abstract: A Ti-W target material for sputtering includes a structure composed of a W phase, a Ti phase, and a Ti-W alloy phase of which 20% or more consist of the area ratio of a micro structure covering the cross section of the Wi-W target material. The Wi-W target material further includes dispersed tungsten particles, the Ti-W alloy phases substantially surrounding the W grains, and the Ti phases dispersed adjacent to the Ti-W alloy phase or the W grains. The formation of the Ti-W alloy phases is capable of reducing a substantial amount of the Ti phase in the target material. It is thus possible to prevent the generation of particles attributable to a difference between sputtering speeds of Ti and Ti-W.

Abstract: A self-expanding flexible pouch (10) that can be used as the measuring device for reconstituting a concentrated product contained therein. The pouch includes an improved one-piece extensible stay (40) located in the throat area of the flexible pouch that is biased toward a relaxed, expanded, circular configuration but is initially held substantially flat in a stressed condition by the sealed top portion (36) of the pouch. When the top portion of the pouch is removed, the improved stay expands to its relaxed, expanded configuration and thereby expands and opens the throat area of the pouch. The improved stay comprises a one-piece, continuous extensible loop having a pair of opposed hinges (44,45). The hinges are thinner in thickness than the remaining portions of the loop and aligned with the side peripheral edges (16,17) of the pouch. Two opposed thick-walled sections are located between the opposed hinges. The opposed thick-walled sections (46,48) provide the automatic opening force for the pouch. The thick-walled sections are substantially aligned with and secured in fixed relation to the front and back sidewall panels of the pouch (12,14). Two ribs (56,58) are located on said opposed thick-walled sections to prevent the stay from sticking together. Four thin-walled transition sections (50) are preferably employed to connect the hinges to the thick-walled sections to form the loop. The thin-walled transition sections are thinner in thickness than the thick-walled sections.
