Abstract:
Disclosed herein is a floating recovery device for underwater equipment. The device includes a recovery body partitioned into a first compartment, a second compartment, and a third compartment by a partition wall, first and second pressure tanks installed in the first and second compartments, respectively, first and second striking parts fastened to the first and second pressure tanks, respectively, to strike the first and second pressure tanks, first and second actuators wirelessly actuating the first and second striking parts, respectively, and a buoyancy generator installed in the third compartment, and inflated by high-pressure gas introduced from the first and second pressure tanks, thus generating buoyancy. Such a configuration allows the pressure tank to be wirelessly struck for the purpose of supplying high-pressure gas to the buoyancy generator and floating the underwater equipment in the event of the loss of the underwater equipment.
Abstract:
Provided is a magnetic memory device and a method of forming the same. A first magnetic conductive layer is disposed on a substrate. A first tunnel barrier layer including a first metallic element and a first non-metallic element is disposed on the first magnetic conductive layer. A second magnetic conductive layer is disposed on the first tunnel barrier layer. A content of an isotope of the first metallic element having a non-zero nuclear spin quantum number is lower than a natural state.

Abstract:
An exemplary method of forming a variable resistance memory may include forming first source/drain regions in a substrate, forming gate line structures and conductive isolation patterns buried in the substrate with the first source/drain regions interposed therebetween, and forming lower contact plugs on the first source/drain regions. The forming of lower contact plugs may include forming a first interlayer insulating layer, including a first recess region exposing the first source/drain regions adjacent to each other in a first direction, forming a conductive layer in the first recess region, patterning the conductive layer to form preliminary conductive patterns spaced apart from each other in the first direction, and patterning the preliminary conductive patterns to form conductive patterns spaced apart from each other in a second direction substantially orthogonal to the first direction.
