A ferromagnetic tunnel junction random access memory includes a ferromagnetic tunnel junction structure including a first ferromagnetic layer, a second ferromagnetic layer disposed adjacent to the first ferromagnetic layer and having a fixed magnetization, and a tunnel insulator layer interposed between the first and second ferromagnetic layers; a conductor plug penetrating the first ferromagnetic layer, the tunnel insulator layer and the second ferromagnetic layer along a center axis; a first selection line coupled to a first end of the conductor plug; and a second selection line coupled to a second end of the conductor plug opposite to the first end. The first ferromagnetic layer has a generally ring shape surrounding the conductor plug and is insulated from the conductor plug. One of the first and second ferromagnetic layers has an antiferromagnetic layer pattern on a portion thereof.

A semiconductor device is provided, which aims to reduce the standby power thereof by reducing the leak between a body and a drain with restraining the effect on a threshold voltage, in order to actualize the highly reliable semiconductor device. When extension regions are formed, an n-type impurity less diffusive than phosphorus (P+), for example, arsenic (As+) is used as an impurity. In addition to ordinary ion implantation with high dose (high concentration) and low acceleration energy, As+ ions are implanted with low dose and high acceleration energy.

A method and device for converting light from a first wavelength to a second wavelength. The method comprises the steps of exciting an electron in a quantum dot with an incident infrared photon having the first wavelength, the excited electron having a first energy, tunneling the excited electron through a barrier into a stress induced quantum dot, and recombining the excited electron with a hole in the stress induced quantum dot, therein producing a photon having the second wavelength, typically in the visible range. The device comprises a substrate, a spacer layer, coupled to the substrate, a second layer, coupled to the spacer layer, wherein the second layer comprises a different material than the spacer layer, a third layer, coupled to the second layer, wherein the third layer comprises at least one quantum dot, a fourth layer, coupled to the third layer, comprising a quantum well corresponding to each quantum dot in the third layer, a fifth layer, coupled to the fourth layer, wherein the fourth layer and fifth layer comprise a strain induced quantum dot corresponding to each quantum dot in the third layer; and a sixth layer, coupled to the fifth layer, the substrate and the sixth layer for contacting the device.
摘要:
A glass panel including a pair of first and second glass sheets (1A, 1B) disposed with sheet faces thereof opposed to each other, a plurality of spacers (5) being interposed between the pair of glass sheets (1A, 1B) for forming a space (4) therebetween; and a sealing material (S) for bonding peripheral edges (3) of the glass sheets (1A, 1B) together for sealing the space (4), the sealing material having a lower fusing temperature than the softening point of the glass sheets (1A, 1B). Each spacer (5) is formed by disposing spacer-forming paste (11) in a predetermined shape on the sheet face of the glass sheet (1A, 1B). Or, the spacer (5) comprises a plurality of spacer bodies (51) two-dimensionally interconnected to each other via a connecting member (52).

In a double glazing including a pair of glass sheets 1, a plurality of spacers 2 disposed between opposed sheet faces of the glass sheets 1 by a predetermined pitch, and a sealing member 4 interposed between the glass sheets 1 along the entire peripheries thereof, with a space V between the glass sheets being sealed in a vacuum condition, each spacer 2 is formed so as to maintain a predetermined distance between the glass sheets when subjected to a static normal external pressure normally applied thereto in the direction of sheet thickness and also to relieve stress through plastic deformation when subjected to an impact dynamically applied in the sheet thickness direction.
摘要:
A grommet for automatic insertion into a mounting hole in a panel by a robot including a head portion 1 having a longitudinal bore for receiving a screw through its center, a bottom portion 3 including a stepped portion 7 elastically engaging the robot arm located within the longitudinal bore; and locking claws 4 attached to the grommet which reflect during insertion of the grommet into the mounting hole and then spring snap into engagement when the locking claws 4 clear the mounting hole, such that the force required to disengage the robot arm 5 from the stepped portion 7 is less than the force required to extract the grommet from the panel, which enables the robot to easily determine whether or not the grommet is accurately inserted into the mounting hole.
