Abstract
Official abstract text for this publication.
An electromagnetic device includes: a fixed iron core; a movable iron core which is disposed to face the fixed iron core and which is displaceable in an axis line direction of the drive shaft; an electromagnetic coil; a permanent magnet which retains the movable iron core at the advanced position; supporting posts which are provided parallel to the axis line direction on both side surfaces of the fixed iron core and support the fixed iron core; an opening-side plate which is provided at one end portion of the supporting post; and a closing-side plate which is provided at the other end portion of the supporting post, wherein the advanced position of the movable iron core is restricted by the fixed iron core and the retreated position is restricted by the opening-side plate.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electromagnetic device comprising: a fixed iron core; a movable iron core which is disposed to face the fixed iron core with a drive shaft fixed to a central portion and is displaceable in an axis line direction of the drive shaft between a retreated position away from the fixed iron core and an advanced position coming close to the fixed iron core; an electromagnetic coil provided in the fixed iron core; a permanent magnet which retains the m…
