  • Publication number: 20140123140
    Abstract: A domain management apparatus instructs physical nodes about the configuration of virtual nodes and virtual links of virtual networks. The physical nodes assign a virtual machine to a virtual node based on the definition of the virtual node contained in an instruction from the domain management apparatus. The physical nodes write a configuration associating virtual interfaces in the virtual node definition with virtual NICs on the virtual machine into a configuration file of the operating system to be started up on the virtual machine before the start-up of the virtual machine and, then, start up the virtual machine. Therefore, it is possible to recognize the correspondence relation between the virtual interface in the virtual node definition and the virtual NIC in the virtual machine without referring to the virtual network assignment result and without waiting for the start-up of the virtual machine.

  • Patent number: 8665053
    Abstract: A method for manufacturing a laminated ceramic electronic component enables formation of a plating film as at least a portion of an external electrode which connects exposed ends of internal electrodes. A component main body including a plurality of ceramic layers and a plurality of internal electrodes partially exposed from the component main body is prepared such that the component main body has a conductive region formed by diffusion of a conductive component included in the internal electrodes at the end surfaces of the ceramic layers located between adjacent exposed ends of the plurality of internal electrodes. The ceramic layers are preferably composed of a glass ceramic containing a glass component of about 10 weight % or more. A plating film is formed directly on the component main body by growing the exposed ends of the internal electrodes and the conductive region as nucleuses for plating deposition.

  • Patent number: 8587919
    Abstract: In a laminate type ceramic electronic component, when an external electrode for a laminated ceramic capacitor is formed directly by plating onto a surface of a component main body, the film that is directly plated may have a low fixing strength with respect to the component main body. As the external electrode, a first plating layer composed of a Ni—P plating film with a P content rate of about 9 weight % or more is first formed such that a plating deposition deposited with the exposed ends of respective internal electrodes as starting points is grown on at least an end surface of a component main body. Then, a second plating layer composed of a Ni plating film containing substantially no P is formed on the first plating layer. Preferably, the first plating layer is formed by electroless plating, whereas the second plating layer is formed by electrolytic plating.

  • Patent number: 8520362
    Abstract: In a method of forming an external electrode by growing plated depositions on exposed ends of a plurality of internal electrodes in a component main body, the component main body is polished to increase exposure of the internal electrodes. To prevent decreased external electrode fixing strength, a radius of curvature is reduced to about 0.01 mm or less for an R chamfered section formed in a ridge section of the component main body during polishing by ion milling, and exposed ends of the internal electrodes are recessed from end surfaces of the component main body with a recess length of about 1 ?m or less. Plating films to serve as external electrodes are formed to extend from the end surfaces of the component main body across the R chamfered section, and include end edges located on at least one of the principal surfaces and the side surfaces.

  • Patent number: 8520361
    Abstract: A laminated electronic component includes a first plating film that defines a base for external terminal electrodes and that includes a plurality of layers including a first layer made of, for example, copper and a second layer provided on the first layer. The total thickness of the first plating film is about 3 ?m to about 15 ?m, and the thickness of the second layer is about 2 to 10 times as thick as the thickness of the first layer. The first layer is formed by electroless plating, and the second layer is formed by electrolytic plating. This formation results in a grain size of about 0.5 ?m or more of a metal grain included in the second layer, and thus makes the film less susceptible to oxidation.

  • Patent number: 8508913
    Abstract: In a method of manufacturing a laminate type electronic component, when a heat treatment is carried out after plating films, which at least partially define external electrodes, are formed by growing plated depositions deposited on exposed ends of a plurality of internal electrodes in a component main body, the presence of the plating films may not only interfere with moisture release, but may also cause blisters or bulge defects in the plating films, while moisture such as a plating solution in the component main body is removed by evaporation. To avoid such problems, cuts to divide exposed ends into multiple sections are formed in extending sections of internal electrodes. Thus, plating films include slits extending in the stacking direction at locations corresponding to positions of the cuts.
