  • Patent number: 6911082
    Abstract: Multi-layered semiconductor nanoparticles having a very narrow grain-size distribution and exhibiting a spectrum having a narrow wavelength-width peak are prepared by a manufacturing method combining a monodisperse semiconductor nanoparticle manufacturing method and a multi-layer semiconductor nanoparticle preparation method. The nature of a solution of monodisperse semiconductor nanoparticles that is stabilized by a surface stabilizer is transformed between hydrophilic and lipophilic by substituting the surface stabilizer. The stabilized semiconductor nanoparticles are then shifted between an aqueous layer and an organic layer. The semiconductor nanoparticles are coated with multiple layers in the organic layer, and the organic layer is drawn off to recover the semiconductor nanoparticles therefrom.

  • Publication number: 20050136470
    Abstract: Provided is an apparatus for detecting biopolymers (DNA) capable of total analysis including non-reacted samples without complicated operations such as washing. A DNA probe is fixed to one of electrodes and direct current voltage is placed between the electrodes, so that it becomes possible to separate complementary strand sample DNA and non-complementary strand sample DNA. By analyzing from a ratio in the whole reaction system, it is possible to obtain clearer results. Further, by using electrophoresis by gel together, it is possible to separate reacted samples and non-reacted samples to perform measurements therefor in the same reaction field.

  • Patent number: 6880409
    Abstract: A shear test apparatus for testing a shear characteristic of a curved panel is provided. The shear test apparatus includes a frame made up of first and second curved side bearing members for bearing a pair of curved sides of the curved panel and first and second flat side bearing members for bearing a pair of flat sides of the curved panel. The second curved side bearing member has an arm extending in a direction perpendicular to the face of the curved panel. The arm has an external force loading point in a position coincident with the center of shear of the curved panel, to prevent twisting of the curved panel.

  • Publication number: 20040206893
    Abstract: A bond separation inspection method using an optical fiber sensor. The method includes a step of embedding a sensor part of an optical fiber sensor in an adhesive joining a plurality of members together. The sensor part is embedded in the adhesive in such a way that the sensor part undergoes a compressive strain. Separation of the bond is detected on the basis of an optical characteristic of the sensor part when light from a light source is directed into the optical fiber sensor.
