  • Patent number: 8242605
    Abstract: In a semiconductor device having an LDMOSFET, a source electrode is at the back surface thereof. Therefore, to reduce electric resistance between a source contact region in the top surface and the source electrode at the back surface, a poly-silicon buried plug is provided which extends from the upper surface into a P+-type substrate through a P-type epitaxial layer, and is heavily doped with boron. Dislocation occurs in a mono-crystalline silicon region around the poly-silicon buried plug to induce a leakage failure. The semiconductor device has a silicon-based plug extending through the boundary surface between first and second semiconductor layers having different impurity concentrations. At least the inside of the plug is a poly-crystalline region. Of the surface of the poly-crystalline region, the portions located on both sides of the foregoing boundary surface in adjacent relation thereto are each covered with a solid-phase epitaxial region.

  • Publication number: 20120094420
    Abstract: A seed substrate is placed to face a formation substrate, and then a gas containing silicon is introduced and chemical vapor deposition is performed. There is no particular limitation on a kind of a material used for the formation substrate as long as the material can withstand the temperature at which the reduced pressure chemical vapor deposition is performed. A group of silicon whiskers which does not include a seed atom can be grown directly on and in contact with the formation substrate. Further, the substrate provided with the group of whiskers can be applied to a solar cell, a lithium ion secondary battery, and the like, by utilizing surface characteristics of the group of whiskers.

  • Publication number: 20110201548
    Abstract: When acute hepatitis progresses to fulminant hepatitis, a large amount of hepatic cells are rapidly broken, and as a result, the prognosis is seriously worsened. Thus, it is important to prognose the progress of acute hepatitis into fulminant hepatitis at an early stage and quickly start an appropriate treatment therefor. Although the prognosis of progress into fulminant hepatitis becomes possible owing to recent advances in test methods and diagnostic techniques, there has been no appropriate prophylactic/therapeutic agent for fulminant hepatitis. The present invention provides a therapeutic agent for acute hepatitis or a prophylactic/therapeutic agent for fulminant hepatitis with little side effect. The problem of the invention was solved by using a composition containing apolipoprotein A-II.

  • Publication number: 20110107064
    Abstract: The present invention realizes an efficient superscalar instruction issue and low power consumption at an instruction set including instructions with prefixes. An instruction fetch unit is adopted which determines whether an instruction code is of a prefix code or an instruction code other than it, and outputs the result of determination and the 16-bit instruction code. Along with it, decoders each of which decodes the instruction code, based on the result of determination, and decoders each of which decodes the prefix code, are disposed separately. Further, a prefix is supplied to each decoder prior to a fixed-length instruction code like 16 bits modified with it. A fixed-length instruction code following the prefix code is supplied to each decoder of the same pipeline as the decoder for the prefix code.

  • Patent number: 7900529
    Abstract: An outer race support plate to which torque of a pinion gear is transmitted from a ring gear via a one-way clutch and thus rotates a crankshaft is provided separately from a flywheel and is mounted to the crankshaft not via the flywheel. As a result, impact noise produced when the one-way clutch engages is not directly transmitted to the flywheel. Accordingly, noise radiation from the flywheel can be suppressed, thereby enabling noise to be reduced.

  • Publication number: 20100251017
    Abstract: The data processor having CPUs each capable of accessing memories enables the processing of a memory error according to the processing mode of the data processor. The CPUs have a memory, and each include a first storing unit capable of storing CPU-identifying information which enables identification of CPU having accessed the memory. At the time of occurrence of a soft error owing to access to the memory, the CPU, having the memory, stores the CPU-identifying information for identifying the CPU having accessed the corresponding memory in the first storing unit, and notifies the interrupt controller of occurrence of a soft error of the memory. After having received an interruption of the memory soft error from the interrupt controller, the CPU uses information stored in the first storing unit to identify the CPU having made the access, and performs the error processing.
