| 20110206231 | ELECTROMAGNETIC CONVERTER - An electromagnetic converter includes a magnetic circuit having permanent magnets, a lower frame for fixing magnetic pole faces of these permanent magnets thereto, an upper frame having an opening formed therein on a side of the other magnetic pole faces of the permanent magnets and plates fixed to the other magnetic pole faces, and a diaphragm having a voice coil pattern arranged on side portions thereof in a direction of the length thereof and on a top portion thereof in a direction of the width thereof. Protruding portions join between these side portions. The periphery of the top portion is joined to the periphery of the opening of the upper frame via an upper gasket. A flange at the edges of the four side portions is joined to an inner surface of the upper frame, i.e., an inner portion of the magnetic circuit via a lower gasket. | 08-25-2011 |

| 20100214047 | ELECTROMAGNETIC TRANSDUCER - Two layers in each of which a plurality of rod-like permanent magnets each having a width Wm, a thickness Tm and a predetermined length are aligned on a plane in such a way that they have opposite magnetic pole orientations alternately and are aligned at a fixed pole pitch τp are arranged to be opposed to each other with the magnetic pole orientation of each magnet in one of the layers being identical to that of the opposing magnet in the other layer, and with the opposing surfaces of the magnets being spaced a distance 2×lg apart from each other, and a vibrating membrane on which coils each having a conductive pattern are arranged is placed in a gap between any two adjacent rod-like permanent magnets in each of the above-mentioned two layers. The arrangement of the rod-like permanent magnets is optimized by using Wm, Tm, τp, and lg. | 08-26-2010 |
| 20080214366 | THERAPEUTIC EXERCISE APPARATUS - A therapeutic exercise apparatus enables a user to depress a pedal by his or her heel without his or her foot coming off the pedal. The apparatus includes a main body, a link having one end mounted through a rotation shaft on the main body so as to be rotatable around its one end by a predetermined angle, a pedal mounted on the other end of the link so as to be rotatable by a predetermined angle and adapted to be depressed by a user's foot thereby to rotate the link; and a foot restraining member provided on the pedal for restraining the foot. The foot restraining member has a base provided with a heel support portion for supporting a heel of the foot, and the heel support portion is disposed on the pedal such that the direction of a depression force of the foot passes through the rotation shaft. | 09-04-2008 |
