Abstract: A composite metal core 30 incorporated in a laminated rubber bearing for damper having two different kinds of metal material. An outer metal 31 includes a material having a high rigidity and an excellent plastic deformability. An inner metal 32 includes a material having low rigidity and an excellent plastic deformability. By making a rising rate of a bending rigidity of the composite metal core higher than a rising rate of a shear rigidity of the composite core, the composite metal core enters a deformation mode in which a superior shear deformability is created. In that deformation mode, the performance of absorbing energy generated in a process of plastic deformation is stabilized. And at the same time, an average horizontal shear yield stress degree of the composite metal core can be set at an arbitral level between the horizontal shear yield stress degrees of the two kinds of metal.

Abstract: There is provided a technique capable of executing a predetermined processing while continuing a database processing. Firstly, the database to be operated is switched from the main database to a duplicate database. The predetermined processing is executed to the main database which becomes the non-operation mode by the switching. Next, a database access request is distributed to the duplicate database which becomes the operation mode by the switching, thereby performing the database processing. Update information indicating the content of the update processing performed to the duplicate database is output. The output update information is reflected on the main data base for which the predetermined processing has been executed. After this, the database to be operated is switched from the duplicate database to the main database.

Abstract: In a liquid crystal display device according to the present intention, a retardation plate and a polarizer plate are stacked on one side of a liquid crystal panel. A second retardation plate and a second polarizer plate are stacked in the other side of liquid crystal panel. The liquid crystal panel has a pair of transparent substrates, i.e., a first transparent substrate and second transparent substrate, and nematic liquid crystal layer is interposed between the pair of transparent substrates. A semi-transmissive film is provided on an inner surface of the second transparent substrate. The semi-transmissive film has both a light reflective property and a light transmissive property, and is totally composed of a dielectric material. More specifically, the semi-transmissive film has a multi-layered laminate structure including high refractivity dielectric layers and low refractivity dielectric layers stacked in an alternating relation.

Abstract: A method of installing a seismic damping wall where the seismic damping wall is attached to the upper floor beam prior to installing the upper floor beam. A hanging plate is placed in the chamber defined by a standing structure plate. The hanging plate is temporarily attached to the standing structure plate. The top edge of the hanging plate is affixed to a horizontal structural beam that upon installation in the building will be an upper floor structural beam. The combined unit, comprising the horizontal structural beam, the hanging plate and the standing plate structure, is placed in position and the horizontal structural beam on the upper floor is installed in the building structure. The chamber is filled with a viscous liquid. The hanging plate and the standing plate structure which were temporarily fastened together are separated from each other. The standing plate structure is lowered down toward the horizontal structural beam on the lower floor.

Abstract: A database system is provided for reading data from a database to a database buffer and performing a physical sequential scan for the data on the buffer. If the preceding request for physical sequential scan is under execution, the database system operates to keep the succeeding request for scan in a waiting state until the preceding requested scan is completed and then execute the succeeding request for scan after the preceding requested scan is completed. If there are more than one succeeding requests for physical sequential scan, they are executed at the same time. Another scanning method is also provided. If the preceding request for scan is under execution, the succeeding requested scan is executed for the data existing after the halfway location at which the preceding scan process now reads the data. The short data is read from its head for completing the subsequent scan.
