  • Patent number: 7975198
    Abstract: A test system for performing a test of a device is provided that comprises a source file of a test plan that describes a program for performing a test, and one or more of elements that are formed in a unit that divides the source file into one or more blocks. The test system further comprises an annotatable object that, when debugging of objects of the source file is performed, manages modification details of the debugging with reference to an element corresponding to a portion where the debugging is performed, and a controller that, after the debugging, rewrites the source file with details after the debugging is performed on an element basis based on the element and the annotatable object.

  • Patent number: 7582351
    Abstract: There is provided a composite thin film-holding substrate in which a composite thin film (4) comprising a filler (2) having a refractive index lower than that of a substrate (1) and a binder (3) having a refractive index higher than that of the filler (2) is formed on a surface of the substrate (1). Light is efficiently scattered when passing through the composite thin film (3) which comprises the filler (2) and the binder (3) having different refractive indexes from each other. In addition, the refractive index of a composite thin film (4) comprising a filler (2) having a low refractive index is low. As a result, the discharge efficiency of light which passes through the composite thin film (4) from the substrate (1) to the external is improved.

  • Publication number: 20070057947
    Abstract: A display program for allowing a user to easily understand changes of observed values is provided. Information necessary for drawing is read from storage means to generate drawing data from the read information, and a bound graph, which is a two-dimensional representation, is displayed as an animation in which measurement points of nodes move up and down over times. This allows the user to observe variations of observed values by using the movement of the measurement points in addition to coloring, which is easy-to-analyze for the user.

  • Publication number: 20070005260
    Abstract: A method for analysis in which a user can readily compare expression data and a pathway with a computer is provided as an alternative to subjective comparison or manual comparison of the expression data and the pathway according to certain criteria. Expression data of a protein/gene other than a target protein/gene is constructed so as to fit in with a pathway on the basis of the target protein/gene expression data; and the protein/gene expression data, in the constructed structure of the expression data, fitting in with the pathway is highlighted while the constructed structure of the expression data is displayed on a display.

  • Patent number: 6762553
    Abstract: There is provided a substrate for a light emitting device which includes an electrically conductive and transparent film which is in contact with a surface of a low refractive index member of which refractive index is greater than 1 and not greater than 1.30. In a preferable embodiment, the substrate further comprises a transparent member on its surface which is opposed to its surface which has the electrically conductive and transparent film. There is further provided a light emitting device which includes such substrate and a luminous layer, and the luminous layer is located on the electrically conductive and transparent film. With such light emitting device, a ratio of light which is withdrawn outside through the low refractive index member is increased, so that a coupling-out efficiency for surface emission of light withdrawn into the ambient air is increased.

    Abstract: An aerogel substrate useful for an electrically conductive substrate, a heat insulating substrate, an optical waveguide substrate, a substrate for a light emitting device or a light emitting device is provided. The aerogel substrate is characterized by comprising a functional layer and an aerogel layer, and an intermediate layer formed between the functional layer and the aerogel layer to allow the functional layer to be formed uniformly thereon. The intermediate layer is formed on at least one surface of the aerogel layer by a gas phase method, by the Langmuir-Blodgett method or by adsorption of an inorganic layered compound; or formed by a hydrophilicizing treatment of at least one surface of the aerogel layer followed by coating and drying an aqueous coating fluid, by an annealing treatment of at least one surface of the aerogel layer, or by a hydrophilicizing treatment of at least one surface of the aerogel layer.

  • Patent number: 6197270
    Abstract: There is provided a process for producing an aerogel which comprises lowering a pH of a water glass solution to obtain a sol, gelling the sol to obtain a hydrogel, replacing water in the gel with an organic solvent, reacting the gel with a hydrophobilizing agent having hydrophobic groups as well as functional groups reactive with silanol groups in liquid phase, followed by supercritically drying; or hydrophobilizing and supercritically drying the resultant gel at the same time. Preferably, the hydrogel is prepared by ion exchanging alkali metals in the water glass solution using an ion exchange resin to obtain a sol which is subjected to suspension polymerization.

  • Patent number: 5830387
    Abstract: A hydrophobic aerogel is fabricated by reacting a polymer having a skeleton structure of (SiO.sub.2).sub.n with a hydrophobic agent having hydrophobic groups as well as functional groups reactive to silanol groups to obtain a denatured polymer, forming a gel consisting of two phase of a dispersing medium and the denatured polymer which was performed a hydrophobic treatment, and then, supercritically drying the gel at temperature and pressure above a critical point of the dispersing medium. The hydrophobic aerogel has improved characteristics free from deterioration in light transmissivity as well as lowered thermal resistance and also free from a dimensional variation such as shrinkage which would otherwise occur by contact with moisture, so that it can maintain the excellent characteristics for long time periods. Particularly, the aerogel is useful as a material having excellent light transmissivity and thermal resistance.
