Abstract: A grip portion configured to support a test piece is disposed at a central part of a base, and a plurality of pillars are erected on the base. A disposition and number of the plurality of pillars are adjusted so that an X-ray emitted from an X-ray source and transmitting through the test piece transmits through zero or one pillar in an optional image capturing direction. It is possible to avoid a situation in which an attenuation rate of the X-ray largely differs due to a difference in an image capturing direction to the test piece. Thus, it is possible to prevent a strong artifact from overlapping a CT image of the test piece in an X-ray CT image. Moreover, a material testing machine is supported by the plurality of pillars to have an accessible state around the test piece. This configuration facilitates handling of the material testing machine.

Abstract: An internal condition of a concrete structure is objectively evaluated irrespective of surrounding noise or the shape of a hammer, by placing a vibration sensor in direct contact with a measuring surface so as to directly convert a vibration generated on the measuring surface into a corresponding voltage without the intervention of a medium such as air thereby to quantify the vibration generated on the measuring surface concerned. A structure diagnosis apparatus of the present invention includes a vibration unit for generating an elastic wave in a measuring object of a concrete structure, a vibration detector adapted to be placed in contact with a surface of the measuring object for detecting a component in a predetermined frequency range of an elastic vibration generated on the surface of the measuring object by the vibration unit; and a display device for displaying a maximum amplitude of an output signal of the vibration detector.

Abstract: An elastic wave generator includes an excitation coil, a magnetostriction oscillator around which the excitation coil is wound and an oscillator support. The excitation coil is wound around the oscillator, which is made of laminated magnetostriction sheets having a positive strain characteristic, in which length varies directionally upon magnetic excitation. The oscillator support has a first support surface bearing against a first end surface of the magnetostriction oscillator, intersecting the direction along which the length of the magnetostriction oscillator changes and a second support surface shrink-fit against a second end surface of the magnetostriction oscillator, intersecting the direction along which the length of the magnetostriction oscillator changes. Thus, the changes in the length of the magnetostriction oscillator due to the magnetic excitation of the excitation coil appearing at the first and second end surfaces is directly supported by the first and second support surfaces.

Abstract: The present application provides a deoxidizer comprising an alkaline compound, silicon, a porous substance, water and at least one organic acid selected from the group consisting of ascorbic acid, isomers thereof and phenol derivatives where pH of an extract when 1 g of the deoxidizer is extracted with 10 ml of water is 8 or lower. The deoxidizer does not generate hydrogen gas and achieves an excellent deoxidizing ability even at from weakly alkaline to acidic regions. When a suppressant for generation of hydrogen is further added to the deoxidizer, generation of hydrogen is suppressed even when the pH is 10 or lower and an excellent deoxidizing ability can be maintained as well. Those deoxidizers do not interfere with the food test using a metal detector.

Both ends of the duct 2 are open, and a water flow generator 4 produces a suction flow for sucking water containing blue green algae into the blue green algae. processing duct 2 from a first end 2a and a discharge flow for discharging the water from the second end 2b.

Abstract: When a waste wax composition containing a filler is treated so that the filler is recovered and thus reclaimed, almost all the impurities coming from the lost wax casting mold may be removed, thereby recovering and thus refining at a high purity, a filler of a lost wax composition. Crude reclaimed filler is first produced by dissolving and dispersing a waste wax composition in an organic solvent, and separating a dissolved wax phase from a solids/wax-containing fraction. The crude reclaimed filler is then dispersed in an aqueous alkaline solution, so as to dissolve and thus remove alkali-soluble impurities, followed by a water-washing process.

Abstract: Fluorine contained within a photocatalyst layer containing titanium oxide and other metallic oxide semiconductors increases the metallic oxide's photocatalytic activity. The described photocatalyst may be in the form of either film, flake, particulate, or fiber. In addition, it can be used for coating the surface of a base material of various forms, such as sheet, film, flake, particulate, bar, or fiber. When using a base material that has an alkaline-containing glass composition, establishing a fluorine-containing layer, such as a layer of fluorine-containing silicon dioxide and other metallic oxide, between the photocatalyst film and the base material can prevent the deterioration of photocatalytic activity of the photocatalyst layer. The fluorine-containing layer functions as an alkaline barrier that controls the diffusion and migration of alkali metallic ions in the glass fibers, such as Na ions, into the photocatalyst layer.
