20110094823 | SOUND WAVE GENERATOR AND METHOD FOR PRODUCING THE SAME, AND METHOD FOR GENERATING SOUND WAVES USING THE SOUND WAVE GENERATOR - A sound wave generator that exhibits more excellent output properties than conventional ones, based on the combination of a base layer and a heat-insulating layer that cannot be expected from conventional techniques is provided. The sound wave generator includes a base layer; a heat-insulating layer disposed on the base layer; and a heat pulse source that applies heat pulses to the heat-insulating layer. The base layer is composed of graphite or sapphire, and the heat-insulating layer is composed of crystalline fine particles containing silicon or germanium. The heat pulse source, for example, is a heat pulse-generating layer that is disposed on the surface of the heat-insulating layer opposite to the base layer and applies heat pulses to the heat-insulating layer. | 04-28-2011 |
20120205762 | MAGNETIC TUNNEL JUNCTION DEVICE - The magnetic tunnel junction device of the present invention includes a first ferromagnetic layer, a second ferromagnetic layer, an insulating layer formed between the first ferromagnetic layer and the second ferromagnetic layer. The insulating layer is composed of fluorine-added MgO. The fluorine content in the insulating layer is 0.00487 at. % or more and 0.15080 at. % or less. This device, although it includes a MgO insulating layer, exhibits superior magnetoresistance properties to conventional devices including MgO insulating layers. The fluorine content is preferably 0.00487 at. % or more and 0.05256 at. % or less. | 08-16-2012 |
