Pointer (16) is mounted to end of shaft (20) having axis of revolution (28) and attached to rotor (30) in bore (34). The rotor (30) is disposed in close-fitting walled cavity (26) so as to define a small substantially air excluded damping fluid filled gap (32) therebetween. Shown near detail arrows (1A) are excess fluid containing reservoir (33) formed by raised torroidal ridges (36, 38). Indicator (10) contains two pairs of field coils (22.1, 22.2, 24.1, 24.2). Adhesion and cohesion help maintain the rotor (30) in cavity (26). The substantial air exclusion helps prevent rotor (30) from moving axially out of cavity (26). A method of assembling to create such conditions therein is also set forth.

    Abstract: A stepping motor-type instrument (6) having drive circuits (3, 4) for driving a stepping motor based on digital signals corresponding to a measured quantity, wherein a needle (9) attached to an end of a drive shaft of the stepping motor indicates a scale (8) on a dial (7) corresponding to the measured quantity. The stepping motor-type instrument (6) comprises a processing means (3) which receives digital signals corresponding to the measured quantity and converts them into an indication angle data at a predetermined period, and a delay means (4) which finds a difference between a preceeding indication angle data and a succeeding indication angle data that are consecutively output from the processing means (3) at a period of conversion, and, when the difference is larger than a predetermined value, converts the signals so that the difference becomes smaller than the predetermined value to output the converted signals as continuous indication angle data. This prevents step-out and makes it possible to reliably follow up a change in the quantity of measurement.

    Abstract: A process is disclosed for correcting a non-linear relation between the electric phase angle and the mechanical output angle of step motors by using a low resolution encoder or the like. This process represents a compromise between the classical regulation of step motors, that requires a high resolution angle detection, and a purely statistical correction of the characteristic curve. The result is a substantial synchronism improvement, for example when conventional claw pole step motors are used for driving the pointer of a display in a motor vehicle. The micro-step control is carried out with a corrected sine wave form. Coefficients evaluated by simplified Fourier synthesis are essentially used to correct the sine wave form.

    Abstract: A miniature crossed coil gauge (30) having an oriented rare earth magnet (40) fixedly mounted on a rotary shaft (38) supplying a magnetic flux directed transverse to the shaft axis. The gauge housing provided by upper (32) and lower (34) bobbins surrounds the magnet and supports the shaft. First (42) and second (44) coils are wound about the gauge housing in a crossed coil orientation encircling the magnet. A flux ring (50) is disposed around the first (42) and second (44) coils axially aligned with respect to the magnet (40). The magnet (40) has sufficient strength and the flux ring (50) is mounted in sufficiently close to the first and second coils to redistribute flux supplied by the magnet so that magnetic flux measured at the surface of the coils is substantially increased relative to the magnetic flux density measured with the flux ring removed. This gauge construction facilitates fabrication of gauges so small that they can be directly mounted on printed circuit boards using conventional electronic component mounting equipment.
