Abstract: An optical connector assembly has a female connector (1) formed in its front surface with a recess (3), and a male connector formed therein with a cavity (7) and in its front surface with a projection (8) which is partly or entirely deformable so that the tip of an optical fiber (10) supported by the projection will be fitted into the innermost portion of the recess without fail. An incoming/outgoing beam surfaces at the innermost part of the recess and at the tip of the projection are formed by the end faces of optical fibers passed through the female and male connectors. A collimator lens (11, 12) may be provided on the end face of each optical fiber (4, 10) which serves to expand the diameter of transmitted beams and deflect the beams in parallel, so that the transmission loss by dust in the water is kept to a minimum level. A device (16, 18) for forming jet streams is provided at the joint surfaces of the male and female connectors which serves to jet water or a detergent stored in a storage means to the end faces of both optical fibers when connecting the connectors and blow away dust, thereby reducing the transmission loss by dust.

Abstract: A system clock is produced either from clock signals (t1) recovered in a clock regenerator, based on surface wave filtered technology and having level fluctuations, or from the digital clock signals (t2) internally generated in, for example, an access controller of a ring network, in response to the level of the regenerated clock signals (t1). The change in the source of the system clock is accomplished after an early detection of the level fluctuations, so that the clock signal (t1,t2) currently connected to the clock line are disconnected and, after a short delay time, the other clock signal (t1,t2) is sychronously switched to the clock line.

Abstract: Les gaz sales à haute température provenant d'un four électrique (1) sont introduits directement dans des préchauffeurs de ferrailles (5a, 5b, 5c), où les ferrailles (6) destinées à être chargées dans un four électrique d'acierie sont préchauffées. L'absorption par les ferrailles d'une partie de la chaleur produite dans le four électrique permet de réduire l'énergie électrique nécessaire pour la fusion de la ferraille et de raccourcir le temps de traitement. Les gaz d'échappement, qui sont chargés d'impuretés après avoir préchauffé les ferrailles, et qui véhiculent des substances malodorantes telles que de la peinture ou de la suie huileuse, traversent une tour de lavage de gaz (19) et arrivent à un précipitateur électrostatique (20) du type humide, où les impuretés sont éliminées avant que les gaz de fumée ne s'échappent dans l'atmosphère. On pulvérise l'eau usée de lavage (23A) et l'eau usée provenant du précipitateur (30A) dans les gaz de fumée (2) provenant du four électrique pour brûler les substances malodorantes véhiculées, de manière à éviter l'évacuation d'eau usée pour prévenir la pollution de l'environnement.

Abstract: A pump arrangement (1) has two alternately conveying separate pumps (2, 3) and one axial piston motor (14). The piston rod (19) of the latter is divided into two sections (20, 21) each assigned to a separate pump (2, 3). Their spacing is variable by means of an adjusting device (22). Each section (20, 21) is connected to an actuating element (39, 40), each of which is assigned to one of the two limit position switch elements (37, 38) and actuates this at the end of each motor stroke. The axial piston motor (14) has two pistons (6, 11), each connected to a piston rod section (20, 21), which pistons are located in the area of an end surface (41, 42) of the piston displacement (15, 16) when the associated limit position switch element (37, 38) is actuated. If a minimum of two double pumps are used, a pump arrangement is created for two-component or multiple- component operation in which the component pumps are steplessly lift- adjustable, do not have to perform any dead travel and thereby work with low pulsation. <IMAGE>

Abstract: A wire stent (10) for insertion and expansion into a passageway comprises a plurality of curved sections that are formed into a generally circular configuration. Adjacent curved sections are joined by a bend or cusp (13), so that a series of alternating opposing loops (15, 16) are formed. The wire stent as formed has a cylindrical shape with a longitudinal opening through which a folded balloon catheter is inserted. The opposing loops are tightly contracted about the catheter so that the cylindrical shape has an overlapping region in which portions of adjacent loops longitudinally overlap. The loops are arranged so that when the balloon catheter is inflated, adjacent loops diverge circumferentially relative to each other, thereby decreasing the overlapping region while increasing the diameter of the cylindrical shape (24, 25). As the diameter of the cylindrical shape increases, the wire stent contacts the surface of a passageway in which the stent is inserted. 
     In a method of the present invention, the wire stent (10) is fabricated from a wire formed into a planar serpentine configuration (30). The wire is centered over a semi-cylindrical trough (43) in a flat plate (40) and then pressed into the trough by a forming bar (45) so that a portion of the wire assumes the semi-cylindrical shape. A pulling tool (47), having a hook (47a) at one end, is engaged at the hook with the exposed loops (13) of the serpentine configuration for pulling the exposed loops over the exposed portion of the forming bar to form a generally cylindrical shape from the wire. Once the wire is extracted from the trough and the forming bar is removed, a folded balloon catheter (22) is inserted through the cylindrical shape and the wire is tightly pressed about the catheter.

Abstract: Nonrefractory micrometer-thick deposited metal or metallization, for example, aluminum and aluminum alloy films, on integrated circuits are planarized by momentarily melting them with optical pulses from a laser, such as a xenon chloride excimer laser. The substrate, as well as any intervening dielectric and conductive layers are preheated to preferably one-half the melting temperature of the metal to be planarized, thereby enhancing reflow of the metal upon melting. This improves planarization and reduces stress in the resolidified metal. Laser planarization offers an attractive technique for fabricating multilayer interconnect structures, particularly where a number of ground or power planes are included. Excellent step coverage and via filling is achieved without damaging lower layers of interconnect.
