  • Publication number: 20240090344
    Abstract: A magnetic storage device includes first and second magnetic layers and a non-magnetic layer, where the non-magnetic layer includes a first oxide layer containing magnesium and oxygen, a second oxide layer containing magnesium and oxygen, a third oxide layer containing zinc and oxygen, a fourth oxide layer containing a first predetermined element and oxygen, and a fifth oxide layer containing a second predetermined element and oxygen, and a crystal structure of an oxide of the first predetermined element and a crystal structure of an oxide of the second predetermined element are each a rock salt structure. The first predetermined element and the second predetermined element each have an oxide formation free energy greater than an oxide formation free energy of zinc, and the oxide of the first predetermined element and the oxide of the second predetermined element each have a bandgap narrower than a bandgap of an oxide of magnesium.

  • Patent number: 11929201
    Abstract: A surface mount inductor includes a coil including a wound portion and a feeder end portion drawn out from the wound portion, a compact that contains a magnetic powder and that encapsulates the coil, and an external terminal disposed on the compact and connected to the coil. The compact has surfaces including two pressed surfaces, opposing each other in a direction of an axis of the wound portion and formed by being pressed in the direction of the axis, and a non-pressed surface, adjacent to the two surfaces and not pressed. The coil is disposed so that the axis of the wound portion is parallel to a mount surface of the compact. The mount surface is included in the non-pressed surface, the feeder end portion is exposed from the mount surface, and the external terminal is formed on only the non-pressed surface and connected to the feeder end portion.

  • Patent number: 8902038
    Abstract: A thermally responsive switch includes a container including a metal housing and a header plate, at least one conductive terminal pin inserted through a hole of the header plate, a fixed contact fixed to the terminal pin, a thermally responsive plate having one of two ends conductively connected via a support to an inner surface of the container and reversing a direction of curvature at a predetermined temperature, and at least one movable contact electrically conductively secured directly to the other end of the thermally responsive plate. Each contact is comprised of a silver-cadmium oxide system contact. The container is filled with a gas containing helium ranging from 50% to 95% so that an internal pressure of the container ranges from 0.38 atmosphere to 0.68 atmosphere at room temperature such that arc generated during opening of the contacts moves on surfaces of the contacts without spreading from the contacts.

  • Patent number: 8902037
    Abstract: A thermally responsive switch includes a hermetically sealed container including a metal housing and a header plate, at least one conductive terminal pin hermetically fixed in a through hole, a fixed contact fixed-to the terminal pin in the container, a thermally responsive plate having one end connected via a support to an inner surface of the container and reversing a curvature direction at a predetermined temperature, and at least one movable contact electrically conductively secured to the other end of the thermally responsive plate. Each contact includes a silver-tin oxide-indium oxide system contact. The container is filled with a gas containing helium ranging from 50% to 95% so that an internal pressure of the container ranges from 0.3 to 0.6 atmosphere at room temperature.
