Patent number: 9174856Abstract: By storing a liquid to be treated in a treatment tank main body 10 having a bottom portion 10g that narrows downward, with particles of materials to be treated dispersed therein, taking out the liquid to be treated from a position lower than the liquid level of the treatment tank main body 10, and returning the liquid to the bottom portion 10g of the treatment tank main body 10, thereby circulating the liquid to be treated while forming a vortex flow within the treatment tank main body 10, and at the same time supplying air bubbles from the lower part of the treatment main unit 10, a first component contained in froths is separated from a second component, which is less susceptible to floatation, contained in the liquid to be treated.Type: GrantFiled: July 15, 2010Date of Patent: November 3, 2015Assignees: JAPAN SCIENCE AND TECHNOLOGY AGENCY, KITAKYUSHU FOUNDATION FOR THE ADVANCEMENT OF INDUSTRY, SCIENCE AND TECHNOLOGYInventors: Yasunori Matsufuji, Koji Takasu, Kiyotaka Tatsumi

Patent number: 7836646Abstract: A wall structure of an architecture is provided, which comprises an outer wall having resistance against earthquakes and wind and an inner wall relatively inferior in the earthquake-resistance and so forth, so that the outer and inner walls are properly combined to share design loads. The wall structure includes the outer wall (2) of bricklaying structure in which bricks (A˜D) and metal plates (51) are stacked. Fasteners (60,62,63,70) extending through the bolt holes (7) of the bricks are tightened, and the vertically adjacent bricks are integrally connected with each other under prestress of the fasteners. The inner wall (3) is constructed inside of the outer wall, and the shear reinforcement member (10,20) connects the inner and outer walls with each other. The inner wall is constructed by a dry type of construction method, which can support a permanent vertical load such as a roof load.Type: GrantFiled: September 4, 2003Date of Patent: November 23, 2010Assignee: Japan Science and Technology AgencyInventor: Yasunori Matsufuji

Patent number: 7823858Abstract: Masonry units (10) are integrally assembled by tightening forces of bolts (60) and nuts (70), in a condition that interlayer metal plates (50) are interposed between the masonry units. A basic form (11) of the masonry unit is contained in a mold for forming the masonry unit. A space (98) for fluidic covering material, which is chargeable with the covering material, is defined between upper and lower faces of the form (11), and the fluidic covering material is charged in the space. The upper and lower faces of the masonry unit are covered with the solidified covering material (12). According to the present invention, high dimensional accuracy of the masonry unit can be ensured, and efficiency of the production process of the masonry units is promoted to improve productivity of the masonry units.Type: GrantFiled: June 28, 2005Date of Patent: November 2, 2010Assignee: Japan Science and Technology AgencyInventors: Yasunori Matsufuji, Tomoyuki Koyama

Patent number: 7561936Abstract: A method for planning the construction of a brick wall, a brick allocating program, and a brick allocating system for allocating bricks, metal plates, and bolts and nuts in a DUP construction method is provided, in which a grid pattern XY coordinate system forming square grids is specified, and odd number layer tightening grids (?) and even number layer tightening grids (?) are alternately set in X- and Y-directions. The brick (10) of an end part of the wall is positioned on a reference grid (?) so that a first square half part of the brick having a bolt hole (30) matches the odd or even number layer tightening grid. The bricks of the odd or even number layer are successively arrayed from the reference grid, and the metal plates are disposed in such a manner that at least one bolt hole (53) of the metal plate (50) is located on the odd or even number layer tightening grids.Type: GrantFiled: July 31, 2003Date of Patent: July 14, 2009Assignee: Japan Science and Technology AgencyInventor: Yasunori Matsufuji

Patent number: 6915614Abstract: A bricklaying structure, a bricklaying method and a brick manufacturing method that is adaptable to a variety of architectural details. Each brick is provided with a bolt hole and through-holes. The bolt hole has a diameter which allows a bolt to extend therethrough and the through-hole has a diameter for containing a nut. The bolt hole and through-holes are arranged on a longitudinal center line of the brick, and a center of the bolt hole, centers of the through-holes and respective end faces of the brick are spaced apart an equal distance from each other in a longitudinal direction of the brick. The bricks and metallic plates are vertically stacked and the bricks are integrally connected under pre-stress with each other by tightening the bolts extending through the vertical bolt holes.Type: GrantFiled: September 5, 2001Date of Patent: July 12, 2005Assignee: Japan Science and Technology AgencyInventor: Yasunori Matsufuji
