  • Patent number: 10355580
    Abstract: A DC-DC converter includes a protection function for handling a reverse connection state, and a protection function for handling a predetermined abnormality other than a reverse connection state, while reducing conduction loss. The DC-DC converter includes a first protection circuit unit, and a switching element on a first conductive path of a high-voltage side switches to an OFF state upon a predetermined abnormal state being detected to prevent a current from flowing into a voltage conversion unit. Furthermore, a reverse connection protection circuit unit and a switching element, on a third conductive path between the voltage conversion unit and a reference conductive path, is configured to switch to an off state if at least a low-voltage side power supply unit is in a reverse connection state, preventing a current from the reference conductive path. Thus, a current is prevented from flowing toward a power supply that is improperly connected.

  • Patent number: 10348187
    Abstract: The present invention realizes a DC-DC converter that is provided with a reverse flow protection function, while reducing conduction loss. A DC-DC converter includes: a voltage conversion unit that steps down a voltage applied to a first conductive path and output the resulting voltage to a second conductive path; a reverse flow state detection unit that detects a reverse flow state of a current flowing through the second conductive path; and a reverse protection control unit that performs a protecting operation when a current flows in a reverse direction. A switching element is provided on a third conductive path that is located between a voltage conversion unit and a reference conductive path, and the reverse protection control unit operates to switch the switching element to an OFF state upon a reverse flow state being detected.

  • Patent number: 8506733
    Abstract: The present invention provides a magnesium-based composite material that can achieve excellent performance such as high tensile strength not only at ordinary temperature but also at high temperature. The magnesium-based composite material of the present invention is Al2Ca-containing magnesium-based composite material, wherein said composite material is obtained by a solid-phase reaction of an aluminum-containing magnesium alloy and an additive, said additive being calcium oxide, and said composite material contains Al2Ca formed in the solid-phase reaction. In the magnesium-based composite material, CaO, in combination with Al2Ca, can be dispersed.

  • Patent number: 7906219
    Abstract: A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate.
