摘要： The system for sensing ions in aqueous solution such as an electroplating bath includes a light source (18) which delivers light including a selected wavelength through a series of optical fibers (20, 24, 26, 32) to probe (14). The probe is partially immersed in the solution (12) and the light is delivered through the solution in the space (94) between prisms (82, 92). The return light is conducted by optical fibers (32,38) to detector or opto-electronic transducer (44). A portion of the original light is diverted by splitter (22) through fiber (42) to opto-electronic transducer (46) so that a comparison of the signals determines the amount of light in selected wavelength which is absorbed in the solution due to ions thereon. The signal processing unit (40) is preferably enclosed in an electromagnetic protected area (16) to avoid the adverse EMI and corrosive atmosphere effects near the electroplating tank (10).

摘要： A shielding string having a conductive surface is arranged between the surface of two juxtaposed parts of a housing for electronic circuits in a groove in one of the housing parts in order to attain shielding against high frequency. This shielding string is arranged before the assembling operation and can readily fall out again prematurely. In order to prevent it from falling out, the form of the groove has several abrupt changes in direction so that the shielding string is pressed against the walls of the groove due to its natural rigidity. Especially with the use of a shielding string with a wire texture at the surface, the grooves are widened in the proximity of the surface.

摘要： A radio-frequency shielded room for a nuclear magnetic resonance imaging system has at least one electrically-conductive shield wall substantially enclosing a predetermined volume adjacent to one end of the bore formed through an imaging magnet within which bore the imaging process is carried out. The at least one wall has an aperture therethrough substantially at and in registration with the one bore end. A hollow shield member, of an electrically-conductive material, extends through the magnet bore and has a first end region periphery aligned with and substantially electrically connected to the entire periphery of the aperture in the at least one wall. A second end of hollow shield member extends at least to the remaining end of the magnet bore, where it is enclosed with an electrically-conductive cap substantially electrically connected about the entire periphery of the hollow shield member second end. The at least one wall, the hollow shield member and the second end cap form a shielded room substantially completely enclosing the volume extending through the magnet bore and adjacent to one end thereof, which volume is effectively shielded from radio frequency signals emanating from outside the enclosed volume.

摘要： A nuclear magnetic resonance apparatus comprises an electromagnetic system in which a shield of a magnetic material is arranged about the coil system for the homogeneous magnetic field. By providing the magnetic material, for example soft iron, directly about the coil system, a comparatively compact magnet with an intensified, interference-insensitive homogeneous magnetic field is obtained. Instead of using a closed cylinder, use can alternatively be made of a cylinder which is formed by rods. The latter is notably attractive for shielding at a larger distance, the original field in the coil then being influenced to only a minor extent. A similar shielding can be obtained by means of a Helmholtz coil pair.

摘要： An electrostatic charging system for an electrophotographic copying machine comprises a photoreceptor, electrostatic charger, an a.c. high voltage transformer for driving the electrostatic charger and a photoreceptor current detector. The transformer is enclosed with a conductive casing insulated from ground and one output of the secondary winding of the transformer is connected to the casing so that leakage current generated in the transformer is subjected to be fed back to the transformer itself through the conductive casing, avoiding the leakage current to flow into the photoreceptor current detector, whereby photoreceptor current can be detected with accuracy.
