  • Publication number: 20150143764
    Abstract: A framework wall structure, a building and a framework wall construction method that may improve structural performance against horizontal force and prevent damage to and around a joining member are provided. A viscoelastic member is sandwiched between joining surfaces of an adjacent member set formed of a stud, a lintel receiving portion and a block so that the viscoelastic member absorbs energy of horizontal force and absorption performance of vibration may be improved. Also, the viscoelastic member may decrease a shear force applied to a nail, prevent that the nail is deformed and a nail hole is enlarged, and prevent damages of the nail and a nailed member.

  • Publication number: 20150001987
    Abstract: An electromechanical transducer includes a first electromagnetic element and a second electromagnetic element, such as electrodes, disposed opposite to each other with a sealed cavity therebetween. The sealed cavity is formed by removing a sacrifice layer and then performing sealing. A sealing portion is formed by superposing a film of a hardened second sealing material that has fluidity at normal temperature on a film of a first sealing material that does not have fluidity at normal temperature.

  • Patent number: 6432472
    Abstract: The invention relates to a nanostructured BaTiO3 film, plate or array that has from 1,000 to 10,000 times the storage capacity of conventional capacitors. The barium titanates are of the formula BaaTibOc wherein a and b are independently between 0.75 and 1.25 and c is 2.5 to about 5.0. The barium titanates may further be doped with a material, “M”, selected from Au, is Au, Cu, Ni3Al, Ru or InSn. The resulting titanate may be represented by the formula MdBaaTibOc wherein d is about 0.01 to 0.25, a is about 0.75 to about 1.25, b is about 0.75 to about 1.25 and c is about 2.5 to about 5.0. X-ray diffraction results illustrate that the crystal structure of the thin films changed from predominantly cubic to tetragonal phase and crystallite size increased with increasing concentration of “M”.
