Abstract: [Object] Provided is a steelmaking slag-coated seed and a method for producing the same, which can be produced with less time and effort of a worker and at lower cost, and yet can include a sufficient amount of a uniform coating layer based on steelmaking slag. [Solution] A steelmaking slag-coated seed includes a seed of a rice plant or the like and a steelmaking slag layer formed on an outside of the seed; the steelmaking slag layer is a covering layer made of steelmaking slag powder obtained by pulverizing steelmaking slag; the steelmaking slag contains a prescribed amount or more of calcium relative to all components of the steelmaking slag.

Abstract: An anchoring device secures tendons formed of a filament body made of fiber reinforced plastic by inserting a male member into a female member to sandwich the tendons between them. Each of the female member and the male member is formed in a tapered shape inclined from one end toward the other end and the female member and the male member include a plurality of mount portions at predetermined intervals in a circumferential direction of an inclined tapered face between the female member and the male member, each of the plurality of tendons being placed on a different one of the mount portions. The length from the one end to the other end of each of the female member and the male member corresponding to a length direction of the tapered face in contact with the tendon is equal to or larger than 130 mm.

Abstract: A toilet housing and waste collection and treatment system purify wastewater to a satisfactory level. When solid wastes are conveyed from individual toilets (31)-(33) into an active circulation chamber (16) in a toilet housing (10), the solid wastes are subjected to air exposure treatments in the active circulation chamber (16). The wastewater exposed to air in the active circulation chamber (16) is then purified through a three-phase flowing structure in first and second active water chambers (51) and (52), with the three-phase flowing structure including water, air, and carrier particles containing aerobic microorganisms. The wastewater so treated flows into first and second sediment separation chambers (53) and (54) where solid wastes are settled down and separated from the wastewater. The treated water is then supplied to a water reservoir (56) which in turns supplies the water to the respective toilets (31)-(33).

Abstract: A casing having an air discharging chamber and an air sucking chamber is provided with a first jetting nozzle and a second jetting nozzle on the underside thereof. The first jetting nozzle and the second jetting nozzle jet supersonic airs such as to approach each other. A sucking nozzle is located between the first jetting nozzle and the second jetting nozzle to allow the working air to be sucked in the casing.

Abstract: Disclosed are a resorcinol resin adhesive composition which comprises a resorcinol resin modified by m-aminophenol, and a process for bonding wood materials by using the same.

Abstract: There is disclosed a method for preparing a resin-reinforced decorative board which comprises the steps of interposing a polymerizable gelatinous substance between a decorative veneer and a base board, pressurizing and heating the materials to permeate at least part of components constituting the gelatinous substance to the decorative veneer or both of the decorative veneer and the base board, and polymerizing the substance to laminate the decorative veneer and the base board through an adhesive layer.

Abstract: A bottom wall of an air discharging chamber in a cleaner head is formed with an air jetting slit. The air jetting slit is arranged in the substantially perpendicular direction to the advancing direction of a panellike body. A bottom wall of an air sucking chamber in the cleaner head is provided with an air sucking slit located in parallel with the air jetting slit. The air discharging chamber includes a supersonic generator therein. The supersonic generator is provided with a continuous groove in parallel with the air jetting slit. The air is turned into an air flow incorporating ultrasonic waves after being passed through the continuous groove, and is successively jetted from the air jetting slit.

Abstract: Disclosed is an adhesive composition for wood comprising a phenol resin adhesive and a phenol resin highly condensed in a mole ratio (F/P) of formaldehyde (F) to a phenol (P) in the range of 0.8:1 to 1.5:1, having a softening point of 100.degree. to 200.degree. C. and having a number average molecular weight of 2,000 or more, whereby the adhesive is accelerated in hardening to impart fast setting-ability thereto, which causes the pressing temperature to be reduced and makes it possible to raise the allowable moisture content of adherends.

Abstract: An adhesive composition can be provided which comprises a vinyl acetate polymer emulsion containing acetoacetylated polyvinyl alcohol as a protective colloid and a calcium silicate alone or the calcium silicate and an isocyanate compounded therein, which can solve the disadvantages observed in the adhesives of systems in which the isocyanates are added to the emulsions like the prior art, and which retains the adhesive strength for a long time, particularly has a little reduction in initial adhesive strength, and is excellent in water resistance (water-resistant adhesion) and also in heat resistance (heat-resistant adhesion) compared to those of the prior-art adhesives.

Abstract: A urea-formaldehyde resin adhesive comprising a powder of a substance having the property of gradually reacting with an acid and thus consuming the acid.
