摘要： A null-adjusting tool for aligning a tilt sensor of the electrolytic liquid type to the vertical is provided. A sensor mounting plate (13) with a tilt-sensing element (16) attached thereto is rotated about a pivot pin (14) by the rotation of a coarse (33) and fine (34) adjustment screw. The coarse adjustment screw (33) acts directly on the sensor mounting plate (13). The fine adjustment screw (34) provides a high degree of position resolution control through a combination of screw thread and lever type mechanical advantage. A digital readout (52) containing a liquid crystal display and self-contained power source is mounted on the null-adjusting tool to provide a visual indication of the angular deviation of the tilt sensor from the vertical during the alignment process.

摘要： Eine Längenmessvorrichtung für fadenartige Gebilde, insbesondere Textilfäden, welche auf einer Kreuzspule auf gewickelt werden, weist zufolge der exakteren Berücksichti gung der geometrischen und kinematischen Verhältnisse an Spulmaschinen eine wesentlich höhere Genauigkeit auf als bisher übliche Längenmessvorrichtungen. Insbesondere kann der Schlupf zwischen der Kreuzspule und der Nuten trommel bei der Längenbestimmung mitberücksichtigt wer den.

摘要： The sensor comprises a body (1) formed by first and second elements (2, 3) of which at least one (2) has a cavity (4), the elements being sealed together to form a chamber (12). The chamber contains an electrically-conductive liquid (14) which fills it almost completely so as to form a bubble (15). At least one main electrode (6) and at least one pair of auxiliary electrodes (5, 9; 7, 10) extend into the chamber (12) through the body (1) and are accessible on the exterior thereof, so that any variation in the inclination of the body relative to at least one predetermined direction causes a movement of the bubble (15) and a corresponding variation in the electrical resistance measurable between each auxiliary electrode and the main electrode. The electrodes are constituted by strips of electrically-conductive material deposited by screen printing on at least one of the said elements by the thick film deposition method.

摘要： Bei einem berührungslosen elektronischen Winkelge ber, mit einem drehbaren Magneten (5) sind zur Erfassung der Winkelstellung rechtwinklig zueinander angeordnete Sensorspulen (11, 12) auf einem für alle Sensorspulen ge meinsamen Ringkern (9) eines nach dem Fluxgate-Prinzip gebildeten Magnetfelddetektors vorgesehen. Vorzugsweise ist der Winkelgeber mit dem drehbaren Magneten und dem Ringkern mit den Sensorspulen in einem gegenüber dem Erdfeld abschirmenden Gehäuse (1) untergebracht. In die sem ist wiederum der Innenraum (2), in dem sich der Ma gnet drehen kann, von einem Innenraum (3) hermetisch abgetrennt, in dem der Ringkern (9) mit den Sensorspulen und die Elektronik (15-19) angeordnet sind.

摘要： In order to detect relative linear displacements between two members (S, C), the transducer includes a fixed part or stator (1) connectible to one of the members (C) and a movable part or rotor (2) rotatably supported by the fixed part (1). A flexible traction member (5) has one end anchored to the other member (S) and its other end connected to the rotor (2) in such a way as to cause rotation of the latter in one sense relative to the stator (1) when the members (S, C) move away from each other. The transducer also includes a return spring (3) which tends to rotate the rotor (2) in the opposite sense of rotation when the two members (S, C) move towards each other. Electrical sensor means output electrical signals indicative of the angular position of the rotor (2) relative to the stator (1) and hence of the relative position of the two members (S, C).

摘要： An encoder for measuring devices having a code plate (10) including binary grating patterns arranged in a given regular fashion and forming a first scale, a linear sensor (14) Including photodiode elements (16) arranged with fixed intervals and forming a second scale disposed in parallel with the code plate (10), and processor means (20) for absolute-interpolating one pitch of the first or second scale on the basis of reading data or information (RI) obtained from the linear sensor (14) corresponding to a relative position of the patterns (12) to the elements (16). When the number of the scale divisions of the first scale within a fixed range is N, the number of the scale divisions of the second scale is N + 1. Accordingly, when the first scale is a main scale, the second scale is a vernier scale. The processor means (20) detects a phase inverting point (X) corresponding to the interpolation point (X) on the basis of the reading data (RI). The processor means (20) performs the absolute Interpolation by detecting the phase inverting point (X).
