す。Both FIGS. 1 and 2 show a conventional open-circuit electromagnetic device, with FIG. 1 being a sectional side view thereof and FIG. 2 being a plan view thereof. 3 and 4 both show an embodiment of this invention, with FIG. 3 being a side sectional view and FIG. 4 being a plan view. 5 and 6 both show other embodiments of this invention, with FIG. 5 being a side sectional view and FIG. 6 being a plan view. In the figure, 1 is a first yoke, 2 is a second yoke, 2c is a high magnetic resistance section, 3 is a movable iron core, 5 is a permanent magnet, and 7 is an electromagnetic coil. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims

[Scope of utility model registration request]

(1) First and second yokes that are arranged to face each other and form a magnetic path, and that are arranged to face each other so as to be able to approach and separate from the first yoke, and that can be opened from the first yoke. a movable iron core that is always biased in the direction of separation and is magnetically coupled to the second yoke; a movable iron core that is disposed between the first and second yoke; A permanent magnet that is attracted to the yoke, an electromagnetic coil that cancels the magnetic flux of the permanent magnet that flows to the movable iron core when energized, and a magnetic coil that is provided on the second yoke so that the magnetic flux is dispersed and flows to the movable iron core. Open type electromagnetic device with high magnetic resistance.

(2) The high magnetic resistance part is constituted by a through hole drilled in the second yoke located between the movable iron core and the permanent magnet. Release-type electromagnetic device described in section 1).

(3) A utility model characterized in that a sliding hole is provided in the second yoke, a movable iron core is loosely fitted into the sliding hole, and an electric/magnetic coil is wound around the outer periphery of the movable iron core. An open-circuit electromagnetic device according to registered claim 1 or 2.

(4) Utility model registration claim (3) characterized in that the high magnetic resistance part is located between the movable iron core and the permanent magnet and is constituted by a notch connected to the sliding hole. Release type electromagnetic device as described.
