摘要： A wire wound core has windings which are wound in a single-layer winding fashion around substantially cylindrical body portions of bobbins. A gap is provided between the inner wall of a hole formed in the substantially cylindrical body portion of each bobbin and the outer peripheral surface of a leg portion of a corresponding core member by a rail-shaped rib disposed on the inner wall of the hole. Another gap is provided between the inner surface of an arm portion of the core member and the outer major of a flange portion of the bobbin by a convex spacer disposed on the outer major surface of the core member.

摘要： An electromagnetic apparatus having an adjusting effective core gap includes: (a) an electrical winding; and (b) a ferrous core situated proximal with the electrical winding. The core has a first terminus and a second terminus arranged in spaced relation to establish a gap distance between the termini in a region in substantial register with the termini. The winding and the core cooperate to establish an inductance related with an electrical current applied to the winding. At least one terminus of the termini has a configuration responsive to varying the current by effecting selective local saturation of successive portions of the at least one terminus for successive values of the current. The selective local saturation establishes successive new effective gap distances. Each respective new effective gap distance is appropriate for establishing a successive new optimum inductance for the current value then extant.

摘要： An inductor with multiple air-gap separations comprises a magnetic core and an enameled wire around the magnetic core. The magnetic core has an air gap with at least a large-gap portion and a small-gap portion. The small-gap portion provides enough inductance in case of low load input to prevent harmonic distortion. The large-gap portion provides enough inductance in case of heavy load output and low input voltage to prevent saturation and temperature rise, thus enhancing power efficiency.

摘要： A planar magnetic device with vertically oriented coil windings having a cross-section of a core with a torroidally-shaped winding structure taken transverse to the plane of the winding structure having two adjacent “winding windows” where the coils are present. One or more gaps in the core materials surrounding the windings store most of the energy generated by the inductor. The gap of height of at least one half the height of the winding structure is confined to the area between the winding cross-sections. Furthermore, in another aspect of the invention the gap is filled with a multi-layer structure of an alternating mono-layer of equally sized ferrite particles and a layer of synthetic resin.

摘要： The current technology involved with overlaying any type of digital subscriber loop (xDSL) service with plain old telephone service (POTS) makes use of two separate transformers, one for POTS and another for xDSL. This invention provides a transformer which combines the POTS transformer and the xDSL transformer into one transformer. This considerably reduces the weight volume and cost of the overlaid POTS and xDSL circuits. In combining the two transformers the magnetic coupling between any one of the windings used for POTS and any one of those used for xDSL must remain weak despite their close proximity. In addition, any two windings of the same type of service, either POTS or xDSL, must remain strongly coupled. This is achieved by choosing a special geometric form for the core and choosing strategic locations for the windings. A portion of the core is dedicated to serve as a shunt for each component of the magnetic field produced by the windings. Strongly coupled windings are wound around a same portion of the core whereas weakly coupled windings are wound around different core portions which are separated by the shunt.

摘要： In a discharge lamp apparatus for a vehicle, it is determined that a grounded condition is present when a lamp voltage is less than a predetermined voltage and a lamp current is less than a predetermined current. Electric power supply to the lamp is stopped temporarily in response to the determination of the grounded condition, and then the lighting operation is restarted again. If the grounded condition is determined again, the above operation is repeated. If this repetition continues for a predetermined period, the lighting operation is disabled continuously. In controlling the lamp, a voltage of a battery is boosted by a voltage booster transformer, which is turned on and off by a MOS transistor so that electric power supplied to the lamp is duty-controlled. An upper limit is set to the duty ratio, and the upper limit is increased as the lamp current decreases, so that the lighting characteristics of the lamp is improved. A starter transformer has a closed magnetic circuit core, and is encased within a ballast casing, which is disposed under the lamp.
