First, the present invention involves adding a curing catalyst to a phenolic resin, polyvinyl alcohol, a pore-forming agent, and a cross-linking agent, and mixing, casting, heating, and drying the same. Next, the plate-shaped porous phenolic resin obtained thereby which has uniform consecutive macropores having an average pore diameter in the range of 3 to 35 &#x3bc;m and formed in a three-dimensional network pattern is immersed with an organic solvent. Thereafter, this block is extracted and pressure is applied thereto. It is possible to obtain plate-shaped activated carbon for use in an electrode of a power-storage device by carbonizing and activating a block which has undergone this procedure by keeping the same at an increased temperature.

A core for a cleaning sponge roller and a cleaning sponge roller set include a core and a cleaning sponge roller mounted on the core. The core for the cleaning sponge roller is in a substantially cylindrical shape including a bore extending in an axial direction and a plurality of small holes communicating between the bore and a circumferential outer surface of the core. The diameter of the bore is 10 mm or more. The diameter of the small holes is 2.5 mm or more. A total of cross-sectional areas of openings of all the small holes is larger than a cross-sectional area of the bore.

Core for washing sponge roller

An approximately cylindrical central core for cleaning sponge roller having an axially extending internal hole and multiple small holes realizing communication from the internal hole to the circumferential external surface. The central core for cleaning sponge roller is characterized in that the external surface of the central core is provided in the circumferential direction with multiple axially slender projections and that the projections each has an axial section viewed from a direction perpendicular to the axial direction that is not flat.

Central core for a cleaning sponge roller

A cleaning sponge roller is made of a polyvinyl acetal-based porous sponge having elasticity in a wet state and comprises a generally cylindrical roll body and a plurality of protrusions molded integrally on the periphery of the roll body. The cleaning sponge roller rotatingly cleans a material to be cleaned by contacting the top portions of the protrusions with the surface of the material and brushing off polishing residues found on the surface of the material. Each of the protrusions has a tapered protruding base portion extending from the periphery of the roll body, and a protruding end portion having almost the same sectional shape from the top end surface of the protruding base portion to the top portion.

In order to prevent biological lesions of plants caused by deficiency in calcium, the present invention is directed to provide a method of preparing at low cost a composition containing saccharides, organic acids and high content calcium component for spraying on plant leaves or fruits. Into an aqueous solution containing glucose and an organic acid, calcium hydroxide or a substance capable of forming calcium hydroxide upon hydration in an aqueous solution is dissolved. The organic acid is at least one selected from formic acid, acetic acid and propionic acid. The adding order of glucose and organic acid to water is not restricted, and the concurrent addition is allowed. The calcium hydroxide is added finally. The amount of glucose is from 15 wt. % to 40 wt. % of water and that of the organic acid is from 3 wt. % to less than 20 wt. % of water.

Dust-preventing method

It is an object of the present invention to provide a soil-borne diseases controlling agent by the use of newly discovered microorganisms having strong antibacterial action. The soil-borne diseases controlling agent according to the present invention is characterized by that the agent comprises microorganisms selected from the group consisting of Bacillus sp. International Deposit Number FERM BP-4375 and Bacillus sp. International Deposit Number FERM BP-4376 as an active ingredient antagonistic against pathogenic Fusarium fungi (Fusarium species).

Anti-fusarium composition containing strains of bacillus Sp., a

Dust-control treatment of dusty powder, which mainly passes through a 100 mesh sieve, such as pigment and fertilizer, is achieved by, firstly blending the dusty powder with fibrillatable polytetrafluoroethylene and a pair of materials capable of initiating an exothermic reaction upon contact, and then subjecting the blended material to compression-shear under the exothermic reaction and raising the temperature of the blended material to 50.degree.-300.degree. C. The polytetrafluoroethylene fibrillates during the compression-shear and the formed fibrils enclose the dusty powder to turn it to a dust-controlled one.

It is an object of the present invention to provide a soil-stabilizing agent with less emission of dust, good reactivity, good behavior at mixing and good dispersibility and a method for soil stabilizing treatment capable of restraining the emission of dust in the procedure of sprinkling and mixing of the soil-stabilizing agent to soil. The soil-stabilizing agent according to the present invention comprises a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin. And the method for soil-stabilizing treatment according to the present invention comprises the following steps; adding a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin to soil, and mixing them under the hydration heat generated by the reaction between the quick lime and/or calcined dolomite with moisture in the soil to form hydrated material. When PTFE is in partially fibrillated state, emission of dust while sprinkling (primary dust) from the soil-stabilizing agent will be restrained as the particles of quick lime and/or calcined dolomite are enclosed in a cobweb-like net of the partially fibrillated PTFE, and emission of dust while mixing (secondary dust) is further restrained by a cobweb-like net of PTFE fibrillated further by mixing under hydration heat generated by the reaction of quick lime and/or calcined dolomite with moisture in the soil.

A filter container includes a sheet having a base with a liquid inlet pipe and a liquid exhaust pipe and a cap that is integrally attached to the base. A disposable unit container is housed inside the sheet, and the disposable unit container contains cartridge filters. The disposable unit container has a liquid inlet port and a liquid outlet port at a bottom portion thereof, these ports being provided with shut-off valves on the inside of the disposable unit container. The shut-off valves are engagable by the inlet and exhaust pipes on the base of the sheet so that the valves are open by engaging the disposable unit container with the base with the sheet, and are closed by removing the unit container from the base. The bottom end cap supports the lower ends of the cartridge filters above the inlet and outlet ports, and defines the inlet and outlet liquid flow paths. Upper end caps are also provided for sealing the upper ends of the cartridge filters.

A solid-liquid separating apparatus for obtaining a liquid component, for example, from a used solid-liquid mixture for reuse of the same, which includes a filtering member having a hollow cylindrical shape made of a hard porous material such as porous ceramics, sintered metal, layered metal net, sintered resin, unwoven cloth, and the like. The hard porous material is provided with continuous air holes and a device is provided for reducing the pressure in the inner hollow space of the filtering member during the rotation thereof. A scraper is provided for scraping a solid component remaining on the filtering surface of the filtering member after the liquid component is sucked into the inner space of the filtering member. The separating apparatus further includes a cutter for effectively removing the solid component and a device which allows reuse of the mixture with solid particles evenly distributed therein. The use of the hard porous material as the filtering member makes it possible to realize a smooth outer surface thereof without deformation to attain an even scraping operation, which results in an excellent filtering ability and improved durability of the apparatus itself.
