20110031545 | Spin transistor based on the spin-filter effect, and non-volatile memory using spin transistors - A spin transistor comprises a spin injector for injecting, from a first nonmagnetic electrode carriers with a spin parallel to a spin band forming the band edge of a first ferromagnetic barrier layer, to a second nonmagnetic electrode layer, as hot carriers. It also comprises a spin analyzer whereby, due to spin-splitting at the band edge of a second ferromagnetic barrier layer, the spin-polarized hot carriers are transported to a third nonmagnetic electrode when the direction of the spin of the carriers injected into the second nonmagnetic electrode is parallel to that of the spin of the spin band at the band edge of the second ferromagnetic barrier layer, whereas the hot carriers are not transported to the third nonmagnetic electrode in the case of antiparallel spin. A memory element is also provided that comprises such a spin transistor. | 02-10-2011 |

20100089164 | UNDERWATER REMOTE SURFACE INSPECTION METHOD AND APPARATUS FOR REACTOR CONSTITUTING MEMBER - In an underwater remote surface inspection method for a reactor constituting member, in order to improve the precision of an operation of inspecting a surface shape of the reactor constituting member, an underwater remote surface inspection apparatus includes a replica picking head, an ultrasonic vibrator, and a replica agent cartridge. The replica picking head is pressed against a surface of core internal structure as an inspection target. A replica agent is supplied from the replica agent cartridge into the replica agent supply region formed inside the replica picking head and contacting with the surface of the core internal structure. After the operation of supplying the replica agent ends, an ultrasonic wave is transmitted from an ultrasonic vibrator to the replica agent inside the replica agent supply region. Accordingly, gas bubbles or liquid bubbles existing inside the replica agent supply region rise up so as to be discharged to the outside of the replica picking head through an air extracting hole. As a result, the gas bubbles or the liquid bubbles do not remain in the surface of the replica agent contacting with the surface of the core internal structure. | 04-15-2010 |

20080308853 | Tunnel transistor having spin-dependent transfer characteristics and non-volatile memory using the same - A MISFET the channel region of which is a ferromagnetic semi-conductor has a feature that the drain current can be controlled by the gate voltage and a feature that the transfer conductance can be controlled by the relative directions of magnetization in the ferromagnetic channel region and the ferromagnetic source (or the ferromagnetic drain, or both the ferromagnetic source and ferromagnetic drain). As a result, binary information can be stored in the form of the relative magnetization directions, and the relative magnetization directions are electrically detected. If the magnetism is controlled by the electric field effect of the channel region of a ferromagnetic semiconductor, the current needed to rewrite the information can be greatly reduced. Thus, the MISFET can constitute a high-performance non-volatile memory cell suited to high-density integration. | 12-18-2008 |
