A method for enhancing an efficacy of an agricultural chemical which comprises incorporating a specific quaternary ammonium enhancer into a diluted solution of the agricultural chemical.

An apparatus for and a method of supplying cold air to a refrigeration compartment door passing through a distributing duct provided in the apparatus, are disclosed. A refrigerator with the apparatus includes at least one compartment for preserving foods at a cold temperature, a first duct for supplying cool air to one portion of the compartment, a second duct for supplying the cool air to the other portion of the compartment and a pair of blower fans mounted in order to introduce the cool air t…

An effective heat-sinking arrangement is realized for circuit elements used in a portable type information terminal having a small restricted space therein. Wherein, a first substrate has a cavity formed in its insulating layer extending to an earthing layer and filled with a silver paste to form a seat for mounting a CPU that can thus thermally contact with the earthing layer, and a second substrate has a cavity formed in an insulating layer in which cavity a heat-conducting cushion bonded to t…

Pyrimidinone derivatives of the general formula: ##STR1## wherein R.sup.1 is hydrogen or alkyl; R.sup.2 is haloalkyl; R.sup.3 is nitrogen or CH; G is optionally substituted ethylene, trimethylene, or vinylene; and Q is selected from several heterocyclic-condensed phenyl groups, are useful as the active ingredients of herbicides because of their excellent herbicidal activity.

In order to effectively perform on/off control for an air-conditioning system carried on an automobile during idling operation of the automobile, if a state, in which a difference between a target idling number of revolution and a net idling number of revolution is larger than a preset difference value, is continued for a preset period of time, then an electromagnetic clutch is disconnected, and a compressor is allowed to be in an operation stop state. After that, if the difference is smaller th…

An isolated DNA having a sequence encoding a polypeptide possessing endo-.beta.-N-acetylglucosaminidase A activity or functionally equivalent variants thereof; and a method for producing a polypeptide possessing endo-.beta.-N-acetylglucosaminidase A activity or functionally equivalent variants thereof using the isolated DNA by recombinant DNA technology.

A process for producing an oxide dispersion strengthened heat resisting powder metallurgy alloy, characterized in that (1) zirconium and/or a rare earth element, such as yttrium, cerium, or lanthanum, are previously added as an oxide former element to a molten mother alloy, (2) an atomizing gas composed of an argon or nitrogen gas containing not more than 5.0% by volume of oxygen is used in the step of gas-atomizing the molten mother alloy, and (3) in the step of consolidating and molding the ga…
