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.

In one aspect, there is disclosed a solenoid having a bobbin with a core wire positioned about the bobbin to form a coil. A power supply wire is connected an end of the core wire and a frame is connected to the bobbin. An overmolded housing surrounds the core wire, the frame and a portion of the power supply wire.

A proportional solenoid (100) of the present invention includes a tubular member (101) in which a first magnetic region (12a) mainly including a ferrite structure, a first semimagnetic region (14a) present at a position spaced apart from an adsorptive surface (11b), the first semimagnetic region including a ferrite structure, a martensite structure, and an austenite structure, and a nonmagnetic region (13) present at a position spaced farther apart from the adsorptive surface than the semimagnetic region, the nonmagnetic region mainly including an austenite structure, are formed continuously and integrally.

A solenoid includes a coil, a cylindrical sliding core, a columnar plunger, a bottomed cylindrical yoke including a cylindrical portion and a bottom portion that is connected to the cylindrical portion and faces a base end surface of the plunger, and the bottomed cylindrical yoke configured to accommodate the coil, the sliding core, and the plunger, a magnetic attraction core arranged to face a distal end surface of the plunger, and a magnetic flux transfer member that transfers magnetic flux between the sliding core and the yoke. When the plunger is closest to the magnetic attraction core, a position of the base end surface of the plunger along an axial direction is the same as position of the end of the sliding core along the axial direction, or is closer to the bottom portion side of the sliding core along the axial direction than the end of the sliding core.

The present disclosure relates to a low friction bearing liner for a solenoid that may include a core layer, a first outer layer overlying a first surface of the core layer, a second outer layer overlying the first outer layer, a first inner layer overlying a second surface of the core layer that is opposite of the first surface of the core layer, and a second inner layer overlying the first inner layer. The first outer layer and the first inner layer may include a fluoropolymer material and may have a melt flow rate of at least about 2 g/10 min at 372° C. The second outer layer and the second inner layer may include a fluoropolymer material distinct from the fluoropolymer material of the first outer layer and may have a surface coefficient of friction of not greater than about 0.2.

This invention entails the use of fractal shapes as cores for electromagnets, and a concurrent shape of a fractal for the windings which surround it. The novelty of this invention lies not only with the shaping, but the advantage of such shaping, which includes producing a smaller form factor electromagnet for the same desired magnetic field strength, when compared to a conventional electromagnet. It will be appreciated that a range of devices including electromagnets, based on such fractal shaping, are additionally novel and include but are not limited to solenoid switches, relays, and other devices in which the fractal electromagnets are used to make a change in state of some device.

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.
