A core includes a winding core, a first flange at a first end portion of the winding core, and a second flange at a second end portion of the winding core. The winding core has first and second surfaces on opposite sides, and first and second side surfaces intersecting the first and second surfaces and on opposite sides. The first flange has first and second surfaces on opposite sides, first and second side surfaces intersecting the first and second surfaces and located on opposite sides, an inner-side end surface connected to the first end portion of the winding core, and an outer-side end surface on an opposite side from the winding core. The inner-side end surface of the first flange has a first inclined surface between the first surface of the winding core and the first surface of the first flange.

A power generating transformer system (PGTS) where the core of the transformer has one of the generalized configurations is presented. Also, a power factor correction method in a power generating transformer system (PGTS) and a PGTS functioning also as power supply are presented. A PGTS generates an AC voltage with the frequency which lets the desired relative phase which is the difference between the phase of the flux at the primary coil and that of the flux at the secondary coil be in a specified range. And by controlling the reactive power at the primary coil of the transformer of the transformer circuit or at the location where the AC voltage is generated, the power factor correction is done using one or more components in the transformer circuit (TC). Finally, block diagrams of PGTS are presented.

The magnetic sensor can prevent an increase of a positional detection error of a subject/object even in the case of applying an external magnetic field with a magnetic field intensity exceeding a predetermined range. A magnetic sensor is equipped with a magnetoresistive effect element (MR element) 11 that can detect an external magnetic field and a soft magnetic body shield 12. The soft magnetic body shield(s) 12 are/is positioned above and/or below the MR element 11 in a side view, and the size of the MR element 11 is physically included within a perimeter of the soft magnetic body shield 12.

A magnetic core for a transformer, which includes a closed ring with a thick part and a thin part. The thin part is magnetically saturated before the thick part when excited by the same increasing magnetic fields. The thin part only operates briefly at or near first quadrant saturation point or a third quadrant saturation point and, for the rest of the time, it operates in a state between the first quadrant saturation point and the third quadrant saturation point. The present invention overcomes the drawbacks of the conventional magnetic core for a self-excitation push-pull type converter, and significantly improves the efficiency of the converter when it is under a light load, and further improves its efficiency while under a rated load. As the number of turns of the coil on the magnetic saturation transformer is reduced, the working frequency of the converter is improved while still keeping the loss low.

A electromagnetic actuating device for a valve, having an armature arranged in a hollow cylindrical armature chamber axially displaceable between two axial stops, wherein the armature chamber is delimited by a magnet yoke . An electrical coil extends coaxially around the armature, and the magnet yoke is at least partially arranged in a housing. The armature has a cylindrical geometry with a base remote from the housing and with a hollow cylindrical end section situated axially opposite. The base is remote from the housing and connected to an actuating plunger. A guide sleeve is mounted axially onto the hollow cylindrical end section of the armature, and on that end of the guide sleeve which is remote from the actuating plunger, there is arranged or formed an adhesion prevention device which prevents or at least greatly impedes axial adhesion of the armature to the magnet yoke. The guide sleeve makes it possible to realize a reduction in width of the parasitic air gap between the armature and the magnet yoke in order to increase the actuating forces of the actuating device with simultaneously reduced number of components.
