Methods for preparing an instrument inductor are provided. The methods can include bundling wires about and within multiple exterior openings of a hollow-cored substrate; and connecting each of the bundles across the openings.

A coil device includes a bobbin, a core body, a wire, and a plurality of terminals. The bobbin includes a pair of connection side portions and a pair of terminal tables. The pair of connection side portions is arranged near both sides of a winding core of the core body and wound by the wire along with the winding core. The pair of terminal tables is arranged on both ends of the connection side portions and respectively includes the terminal protruding outward in a winding axis of the winding core. The core body includes a pair of flanges arranged on both ends of the core body in the winding axis. Each of the terminal tables includes a flange storage recess configured to contain the flange.

A sound wave treatment device for medical treatment using compression waves, in particular for lithotripsy, includes a sound wave generator, a plurality of piezo elements that are coupled to the sound wave generator, and, an electrical high voltage unit that is set up for supplying the piezo elements with high electrical voltage. The high voltage unit has a blocking converter unit having a transformer, wherein the transformer has a primary coil, a high voltage coil, and spacers, wherein the high voltage coil has a plurality of high voltage windings that are embedded in an insulating mass and are positioned using the spacers such that adjacent high voltage windings are at a defined distance (a) from one another due to the spacers.

A winding bobbin includes a bobbin main body constructed in a ring shape so as to house a ring-shaped core and a plurality of partitions that are provided at intervals in a circumferential direction of the bobbin main body and formed so as to protrude from a surface of the bobbin main body. A winding is formed by winding a conductive wire in winding regions on the surface that are partitioned by the partitions. The partitions each include a flange that is formed of a U-shaped plate that protrudes from the surface at three positions out of four positions that are an outer circumference, an inner circumference, and two sides of the bobbin main body, with one position omitted, and a protrusion that is formed so as to protrude from at least one out of two opening-side ends of the flange.

A bobbin and coil architecture is provided for use in an inductive sensor. The architecture eliminates the need for coil shielding and reduces the sensor's sensitivity to temperature and proximate mounting hardware. In one or more embodiments, all or portions of separate coils are located in a common slot on the bobbin, rather than being segregated into separate slots. In an example configuration, two receiver coils may be located in respective two slots on the bobbin, and a transmitter coil may divided into two substantially equal subsets of windings, with each subset wound together with one of the receiver coils in a common slot. This yields a symmetrical and balanced winding architecture that requires fewer slots relative to designs that segregate all coils into separate slots.

An ignition coil has a ferromagnetic core, a primary coil surrounding a portion of the core and wrapped helically with a conductor, a winding form having partitions extending outwardly of a tubular surface of the winding form, and a secondary coil wrapped on the winding form. The partitions define a plurality of annular coil chambers including central chambers and end chambers. The end chambers have a spiral land. The secondary coil includes coil sections in each of the plurality of coil chambers. The secondary coil has coil turns in the end chambers in a spiral configuration on the spiral land and increasing progressively in diameter toward the central chambers.

A coil device includes a bobbin, a first winding part, and a second winding part. A partition portion is formed on an outer peripheral surface of the bobbin. The first winding part is wound around the outer peripheral surface at one side of the partition portion. The second winding part is wound around the outer peripheral surface at the other side of the partition portion and has an inner winding layer and an outer winding layer located farther to the outer peripheral surface at the other side than the inner winding layer.

An ignition coil has a core with a longitudinal axis, a secondary winding extending around the core, a sleeve extending around the core, a primary winding wrapped around the sleeve, and a controller connected to the primary winding so as to oscillate alternating current to said primary winding. The secondary winding has a high-voltage end and a low-voltage end. The primary winding is in spaced longitudinal relationship from the secondary winding. Specifically, the primary winding is located longitudinally away from the high-voltage end of the secondary winding. A bobbin is positioned over and around the core. The secondary winding is wrapped around at least a portion of the bobbin.
