Abstract
Official abstract text for this publication.
A power generation device includes a first magnet member, a second magnet member which is disposed such that the N pole side thereof is in the opposite direction to the N pole side of the first magnet member, a yoke which is disposed between the first magnet member and the second magnet member, an induction coil which is disposed at an outer periphery of the yoke. When the first magnet member and the second magnet member slidingly move in synchronization or when the yoke slidingly moves, the direction of a magnetic flux flowing in the yoke changes to generate an electromotive force in the induction coil.
First claim
Opening claim text (preview).
What is claimed is: 1. A power generation device comprising: a first magnet member; a second magnet member, an N pole side of the second magnet member being disposed in an opposite direction to an N pole side of the first magnet member; a yoke disposed between and on a line connecting the first magnet member and the second magnet member; and an induction coil disposed at an outer periphery of the yoke, wherein: the yoke includes a first portion and a second portion, the first portion and the second portion are not surrounded by the induction coil, the first portion is positioned in a first direction from the induction coil, the second portion is positioned in a second direction opposite the first direction from the induction coil, when the first magnet member moves toward the first portion and the second portion, the second magnet member moved away from the first portion and the second portion, and when the second magnet member moves toward the first portion and the second portion, the first magnet member moves away from the first portion and the second portion. 2. The power generation device according to claim 1 , wherein the yoke is fixed. 3. The power generation device according to claim 1 further comprising one of a spring and an elastic member for applying a force in a direction in which the first magnet member and the second magnet member slidingly move. 4. The power generation device according to claim 1 , further comprising: a first auxiliary yoke; and a second auxiliary yoke, wherein the first magnet member is positioned between the yoke and the first auxiliary yoke, and the second magnet member is positioned between the yoke and the second auxiliary yoke. 5. The power generation device according to claim 1 , wherein the first magnet member and the second magnet member are fixed. 6. The power generation device according to claim 5 further comprising: a first auxiliary yoke; and a second auxiliary yoke, wherein the first magnet member is positioned between the yoke and the first auxiliary yoke, and the second magnet member is positioned between the yoke and the second auxiliary yoke.
