Patent EP-0255044-A1 (EP)
Inventor: MARUYAMA YOUJI
IPC: G11C11/14
Filed: 1987-07-23
Abstract: A Bloch line memory device in which a stripe magnetic domain (1) is formed within a magnetic film for holding magnetic bubble domains, and Bloch line pairs (4a,4b; 5a, 5b) are stored as information carriers within a magnetic wall defining the magnetic domain. In order to write Bloch lines into the magnetic wall of the stripe magnetic domain, current (I g ) is caused to flow through a single conductor (14) which is so disposed as to cross the mgnetic wall of the stripe magnetic domain. On this occasion, the current through the single conductor (14) is so directed as to generate an in-plane field opposite in sense to magnetization within the magnetic wall of the stripe magnetic domain (1).

Abstract: Bei der feldorientierten Regelung einer Asynchronmaschine, deren Flußwinkel von einem Flußrechner aus Strom und Spannung als Integral der EMK berechnet wird, muß bereits beim Anlauf der Maschine der richtige Flußvektor zur Verfügung stehen. Hierzu wird an einer Eingabeeinrichtung (E1, E2) durch einen konstant vorgegebenen Anfangswinkel (φM0*) eine Achse (Mφ1) eines Modell-Koordinatensystems sowie die auf das Modell-Koordinatensystem bezogenen Komponenten (i0*, iM*=0) eines zu dieser Achse parallelen Vektors bestimmt. Dieser wird bei erregter, aber stillstehender Maschine mittels des vom Flußrechner errechneten Feldwinkels (φs) zur Bildung der Umrichter-Steuer-größen ins Ständerkoordinatensystem überführt. Die Win-kelabweichung (φM0*-φs) des errechneten Feldwinkels vom Anfangswinkel wird durch einen Regler (CR) zur Korrektur des errechneten Feldwinkels verwendet. Bevor von der Ein-stelleinrichtung auf den betriebsmäßig vorgesehenen Sollwertgeber (RV) umgeschaltet wird, nimmt daher der errechnete Feldwinkel (φs) den Anfangswinkel (φM0*) an und die Regeleinrichtung erzwingt über den Umrichter einen hierzu parallelen Ständerstrom und Maschinenfluß. Gleichzeitig kann auch der zur Berechnung des Flusses verwendete Parameter des Ständerwiderstandes abgeglichen werden.

Abstract: A process for separating special steel components from lump shredder scrap includes first removing the ferromagnetic content from the shredder scrap and thereafter dividing the shredder scrap into a normal size fraction and an undersize fraction. The undersize fraction is then treated by separating the special steel content from the undersize fraction by a magnetic drum having a field strength above 0.2 tesla.

Abstract: A video signal recording and playback apparatus for recording each field of a video signal as a plurality of segments on a plurality of tracks, including means (23) for inserting segment index signals after conversion of the video signal to a recording signal, to be recorded together with the recording signal to designate the respective segments. During varied-speed playback operation, the segment index signal are detected (33) in the playback signal, and the data thus obtained are used to control the operation of a memory (35) which temporarily stores successiveliy produced portions of the playback signal. A playback signal can thereby be obtained by combining output signals from the memory (35), which will produce a satisfactory display image during varied-speed playback operation, e.g. during high-speed playback, with only simple signal processing being required.

Abstract: Un dispositif thérapeutique compact de base fréquence peut être directement attaché à un objet que l'on veut stimuler, tel qu'un corps humain. Des impulsions survoltées de haute fréquence sont produites avec l'énergie électrique fournie par une petite source d'énergie et sont temporairement stockées jusqu'à ce qu'une intensité prédéterminée des impulsions, susceptible de stimuler le corps vivant, soit atteinte. La charge électrique stockée est ensuite déchargée pour générer des impulsions de basse fréquence ayant une amplitude qui agit efficacement en tant que stimulus électrique. On peut ainsi appliquer à l'objet des stimulus électriques ayant une amplitude et une stabilité suffisamment élevées tout en utilisant une petite source d'énergie de faible capacité.

Abstract: The flexible tiller (10) has a center (12) and two end sections (13, 14), each including a cutter bar (15, 16, 17), frame (18, 19, 20), apron (52) and grooming bar (53). The two tiller end sections (13, 14) are connected flexibly to the ends of the center section by frame to frame hinges (22) and by cutter to cutter universal joints (24), so that the end sections can ro­tate freely about the hinges (22). The tiller center section (12) is secured to the towing mechanism (11) to oscillate about a central horizontal axis (29) in the direction of travel. The oscillating center section (12) and the two pivotally attached end sections (13, 14) cooperate to enable the tiller (10) to closely conform to and thoroughly groom rolling snow paths without reducing them to flat ones. The rolling paths are enjoyable to ski, and are slower and safer. A controllable hydraulic ram (36, 37) is mounted to act across each hinge (22), so that the operator may select the degree of bending permitted at each hinge (22), and may hydraulically lock it into selected position, if desired.

Abstract: A sensor (CTD) which is formed with pick-up elements (D) for converting incident radiation (L) into electric charge packets which can be shifted to a sensor signal output (TO) through sensor elements under the control of clock pulse signals (CS1) may be beset with unwanted signal smear caused by the shifting process. To eliminate this, the relevant pick-up device includes a signal smear reduction circuit (SRC) which is specifically operative for a smear component produced during instantaneous shifting after a radiation information integration period. To this end, the signal smear reduction circuit (SRC) includes a signal subtraction circuit (SSC) which has an input (T1) coupled to the sensor signal output (TO), an output (T3) being coupled to an output (T4) of the pick-up device for the supply of an output signal with reduced signal smear and to an input (T5) of a series circuit (MEM, MUL, SC) comprising at least a summing memory device (MEM) and a signal attenuation circuit (MUL), whilst a series circuit output (T12) is coupled to another input (T2) of the signal subtraction circuit (SSC). A signal switching device (SC) which forms part of the series circuit (MEM, MUL, SC) of which is present between the sensor signal output (TO) and the input (T1) of the signal subtraction circuit (SSC) switches periodically on and off at a clock pulse frequency (1/CP) which is associated with the signal supply to the signal smear reduction circuit (SRC) and the summing memory device (MEM) has a reset (RS) which is operative before the signal supply to the signal smear reduction circuit (SRC) commences.

Abstract: A mining machine, in the form of a ranging drum shearer has a ranging arm 11 pivotally mounted on at least one end of the body 10, of the shearer. The arm 11 carries a cutter drum and an associated transversely mounted electric motor 12 which drives the cutter drum of said arm. The electric motor is contained withln a transversely disposed cylindrical shroud 20 mounted on or integral with the ranging arm 11 and spaced longitudinally of the axis of rotation 14 of the ranging arm 11. The machine runs in both directions on a track 16 which has a conveyor 16A which runs in one direction. Therefore, when the machine is running in the direction opposite to that of the conveyor a coal sizer 18 and an associated transversely mounted electric motor 19 are spaced in advance of the leading end face of the body. The coal sizer 18 is carried by a mounting 23 which is pivotally connected to the body 10 on the ranging arm hinge 14 and has a two-part sleeve 24A, 24B which locates around the shroud 20 and is rotatable relative to the shroud. When the ranging arm 11 pivots up or down, the shroud also pivots but the coal sizer 18 is restrained to remain in a pre-set stationary position so that it can break large lumps of cut coal to a size which enables the lumps to pass along the conveyor 16A under the machine body 10. The coal sizer 18 is restrained from pivoting with the shroud by a position-control arm 30 which is pivotal on the machine body and extends longitudinally alongside the coal sizer. The control arm 30 can be pivoted by a hydraulic ram 33 to locate it in the pre-set position. The arm 30 has a keyway 31 into which locates a key 32 coaxial with the coal sizer. The key 32 pivots and slides along the keyway as the ranging arm pivots and the sleeve 24 rotates about the shroud 20 so that a distance 'L' between the axis of the coal sizer and the shroud remains constant. When the control arm 30 is pivoted to its lowermost position, the drum drive motor 12 can be removed, unobstructed, from the shroud 20.
