Disclosed is a method which can readily design an agricultural chemical-containing resin composition having a desired release rate history and can produce the agricultural chemical-containing resin composition. Specifically disclosed is a method for producing an agricultural chemical-containing resin composition, including: respectively selecting an acetamiprid content Acand a hydrophilic white carbon content Cain the composition relative to the total mass of acetamiprid, a styrene-maleic anhydride copolymer or a styrene-maleic anhydride copolymer-mixed resin, and hydrophilic white carbon, so as to satisfy the inequations of: 0.524&#xd7;Ac+1.422&#xd7;Ca&#x2212;6.009&#x2266;40% by mass, 5% by mass&#x2266;Ac&#x2266;35% by mass, and Ca&#x2267;0.1% by mass; and mixing the acetamiprid, the styrene-maleic anhydride copolymer or the styrene-maleic anhydride copolymer-mixed resin, and the hydrophilic white carbon, so that the thus selected contents Acand Cacan be achieved.

Method for producing agrichemical-containing resin composition

A method of producing a suspended agricultural chemical composition, includes the steps of: grinding an agricultural chemical active ingredient; mixing at least water, a polyalcohol, a mineral salt, and a surfactant to produce a solution; adding to the solution the ground agricultural chemical active ingredient and a suspension stabilizer, to produce a mixture; heating the mixture to 40 to 70&#xb0; C. while stirring; cooling the heated mixture to 10 to 25&#xb0; C.; and wet-milling the cooled mixture at 30&#xb0; C. or below. Alternatively the method includes the steps of: grinding an agricultural chemical active ingredient; mixing at least water, a polyalcohol, a mineral salt, and a surfactant to produce a solution; adding to the solution the ground agricultural chemical active ingredient and a suspension stabilizer to produce a mixture; wet-milling the mixture; heating the wet-milled mixture to 40 to 70&#xb0; C. while stirring; and cooling the heated mixture.

Method of producing suspended agricultural chemical composition

The present invention provides cyclohexanedione-based agricultural-chemical emulsion compositions where active ingredients of agricultural chemicals are emulsified and dispersed in spraying water, especially cyclohexanedione-based agricultural-chemical emulsion compositions where alkylphenol derivatives are not used in emulsifiers and emulsification stability and preservation stability of technical products are favorable. The cyclohexanedione-based agricultural-chemical/herbicidal emulsions where preservation stability of active ingredients of agricultural chemicals and emulsifiability are favorable are obtained by using an amine salt of alkylbenzenesulfonate with poor water solubility as an emulsifier.

Agricultural-chemical emulsion composition

A clathrate compound containing a polymolecular host compound as a host compound and an agricultural chemical active ingredient having a saturated solubility in water at 25&#xb0; C. of not less than 500 ppm as a guest compound.

Clathrate compound, method for controlling concentration of aqueous agricultural chemical active ingredient solution, and agricultural chemical formulation

The present invention provides a clathrate compound characterized by containing: a polymolecular host compound as a host compound; and an agricultural chemical active ingredient having a saturated solubility in water at 25&#xb0; C. of not less than 500 ppm as a guest compound. The present invention also provides a method for controlling the concentration of an aqueous agricultural chemical active ingredient solution, characterized by containings a step of including an agricultural chemical active ingredient having high saturated solubility in an interior space formed of a polymolecular host compound, thereby maintaining the saturated solubility of the agricultural chemical active ingredient in water within a predetermined concentration range. The present invention also provides an agricultural chemical formulation containing the clathrate compound. The present invention also provides an agricultural active composition containing the clathrate compound and a synthetic pyrethroid.

The present invention provides a sealed battery, in which leakage can be detected in reliable manner, a method for manufacturing the sealed battery, and a method for detecting leakage of the sealed battery. The invention provides a sealed battery containing helium, a method for manufacturing the sealed battery, and a method for detecting leakage. From inside a battery case sealed except an electrolyte inlet, the air is withdrawn, and pressure is applied by a gas containing helium under pressure higher than the atmospheric pressure through the electrolyte inlet. The electrolyte is injected, and after the electrolyte and the gas containing helium have been injected, the electrolyte inlet is sealed.

Sealed battery and method for manufacturing sealed battery

The present invention provides a liquid injection apparatus for injecting liquid into a container, comprising an injection chamber, a container for a liquid to be injected and entirely sealed except an injection port is placed in the injection chamber with the injection port directed to the bottom, an injection cell comprising at least one unit injection cell to accommodate the liquid to be injected is installed in the injection chamber, there is provided pressure regulating means to reduce the pressure in the injection chamber and to regulate pressure in the injection chamber to the atmospheric pressure or to a level higher than the atmospheric pressure, the pressure in the injection chamber is reduced to a level lower than the atmospheric pressure by the pressure regulating means at least once, and then, by maintaining the atmospheric pressure or the pressure higher than the atmospheric pressure, the liquid is injected through the injection port.
