  • Patent number: 8323620
    Abstract: An ultrasound contrast agent composed of at least one kind of low-boiling water-insoluble substance (with a boiling point lower than 37° C.) and at least one kind of high-boiling water-insoluble substance (with a boiling point higher than 37° C.). The former vaporizes to absorb ultrasonic energy upon application of ultrasound, thereby causing the latter to vaporize secondarily, with the resulting bubbles producing an echo image. It is less liable to bumping and hence safe.

  • Patent number: 8232830
    Abstract: A highly efficient rectifier can readily replace a two-terminal diode. Its conduction losses are reduced from that of the two-terminal diode. Connected between the source and drain of a MOSFET including a parasitic diode are a micro-power converter section for boosting a conduction voltage Vds between the source and drain to a predetermined voltage, and a self-drive control section that operates based on a voltage output from the micro-power converter section. When the source and drain are conductive with each other, the micro-power converter section generates, from the conduction voltage Vds, a power source voltage for the self-drive control section, and the self-drive control section (4) continues drive control of the MOSFET.

  • Patent number: 8227710
    Abstract: Provided is a wiring structure and the like which can completely connect a wiring layer to a body to be wired while keeping insulation between two adjacent wiring layers and realize high density packaging due to a narrowed pitch. In a semiconductor-embedded substrate, a conductive pattern is formed on both sides of a core substrate and a semiconductor device is placed in a resin layer stacked over the core substrate. The resin layer has via-holes so that the conductive pattern and a bump of the semiconductor device protrude from the resin layer. Inside the via-holes, the bump and conductive pattern are respectively connected to via-hole electrode portions whose cross-sectional area has been increased toward the bottom of the via-hole. A void is defined between the via-hole electrode portion and upper portion of the inner wall of the via-hole.
