| 20110026296 | Nonvolatile Optical Memory Element, Memory Device, and Reading Method Thereof - A nonvolatile optical memory element in which a ferromagnetic body is provided on a semiconductor causes such a problem that in a case where magnetization of the ferromagnetic body is read by light, magneto-optical response becomes very small when the ferromagnetic body is small in volume. The present invention provides a memory element, a memory device, and a data reading method, each of which is applicable to data reading from a nonvolatile optical memory element. In a nonvolatile optical memory element having a structure in which a ferromagnetic body is provided on a semiconductor that is connected to an optical waveguide, electrons are injected into the semiconductor via the ferromagnetic body so that the electrons that are spin-polarized according to a magnetization direction of the ferromagnetic body are injected into the semiconductor, thereby enlarging a region in which a photomagnetic effect occurs effectively. By applying an electric pulse and an optical pulse to the nonvolatile optical memory element, it is possible to effectively read recorded data according to a magnetization direction of the ferromagnetic body. | 02-03-2011 |

| 20090186738 | Vehicular Drive Force Distribution Device - The rotation of a first rotating element is shifted in speed by a speed shift device, and is transmitted to a second rotating element or a third rotating element of a differential device via a first clutch or a second clutch. In this manner, the torque of right and left driving wheels can be controlled. Furthermore, in conjunction with limitation of the differential motion, the amount of torque transmitted to a fourth rotating element is eliminated by allowing the speed shift device to freely rotate, and the accumulated amount of sliding of friction engagement elements at the time of differential motion limitation can be reduced by completely engaging the first clutch and the second clutch without allowing them to slide. Thus, the differential motion limitation control can be realized without a need to increase the size of the first clutch and the second clutch. | 07-23-2009 |
