    摘要: A superconductive transmission line (20) is formed of mixed metallic oxide ceramic material, particularly Y₁Ba₂Cu₃O 7-x drawn epitaxially upon a substrate (76). The superconductive material has basal crystallographic planes (44) in alignment with copper oxide of the ceramic material. The planes (44) are parallel to the substrate (72). The transmission line (20) is constructed of a plurality of electrically conductive elements (38, 40, 56, 60), each of which is formed of the superconductive material. The conductive elements (38, 40, 56, 60) are arranged with the basal crystalline planes (44) parallel to an axis (46, 72) of the transmission line, along which axis power is to flow. Thereby, magnetic fields (48) induced by currents flowing in the conductive elements (38, 40, 56, 60) intersect the conductive elements (38, 40, 56, 60) perpendicularly to the basal crystallographic planes (44) to maximize the current which can flow while retaining linearity between magnetization and applied magnetic field. Thereby, alternating current can be transmitted by the transmission line without the introduction of hysteresis losses which would develop heat and quench the superconducting characteristic of the transmission line (20).

    摘要: 57 A linear disk actuator is disclosed incorporating a magnetic circuit for reducing stray magnetic fields in the region of the disks and recording heads of a magnetic recording disk system. The moving part of the actuator is provided with a plurality of coils mounted thereon, at least two of which are energised simultaneously and in magnetically opposing relationship to reduce the amplitude of the stray magnetic fields. Movement of the actuator is achieved by both energised coils interacting with a set of alternating poles positioned on the stationary part of the actuator.

    摘要: Die Einrichtung benutzt eine Tastatur, unter der eine akustische Verzögerungsleitung (4) in Serpentinen angeordnet ist, wobei letzterer Erregerstromimpulse zur Magnetfelderzeugung zugeführt werden. Nahe der Leitung angeordnete Magnete (3, 5) erzeugen magneto-akustische Impulse, die der Leitung (4) entlanglaufend hintereinander am einen Ende derselben bei einer Sensorspule eintreffen. Für jede Taste (6) der Tastatur sind wenigstens zwei Magnete vorhanden, deren einer unbeweglich befestigt ist. Der zweite Magnet (5) ist durch Betätigung der betreffenden Taste zur Verzögerungsleitung hin- und zurückbewegbar.
    Der feststehende Magnet (3) erzeugt an der jeweiligen Datenposition für jeden der Verzögerungsleitung (4) zugeführten Erregerimpuls einen akustischen Impuls bzw. ein Synchronisationssignal, das die Datenposition entlang der Leitung definiert. Bei Tastenbetätigung erzeugt der zweite Magnet (5) simultan mit dem ersten (3) einen weiteren Impuls, welcher der versetzten Lage entsprechend dem Synchronisationssignal vor- oder nacheilen kann. Eine angeschlossene Auswertschaltung (1-35) eruiert das Auftreten eines oder zweier Impulse pro Datenposition.

    摘要: @ A pen (10) has a conductive casing (12) with an ink writing tip (21). The tip (21) is detachably mounted on the movable end of a piezoelectric tube (26), which has an opposite end (27) fixed to a mounting in the casing (12), so that the tube is mounted in cantilever fashion. The tube (26) has inner and outer tubular electrodes between which an electric signal is generated according to the pressure on the tip during pen use. A second piezoelectric tube (24), also mounted in cantilever fashion so as to have a movable end (25) and a fixed end (23), is located behind the tip and has a different arrangement of five electrodes for providing x, y signals according to the transverse accelerations of the pen during use. The pressure and accelerometer signals are electrically processed by electronic circuitry (22) before leaving the pen on cable (8).
