    摘要: This invention provides 1,3-oxazin-4-one derivatives represented by following general formula (I): ##STR1## in which R.sup.1 represents a phenyl group which may be substituted; R.sup.2 represents a hydrogen atom or a lower alkyl group; R.sup.3 represents a hydrogen atom, a lower alkyl group, an aralkyl group or a phenyl group which may be substituted; R.sup.4 and R.sup.5 each independently represent a lower alkyl group; and W represents an oxygen atom or a group represented by the formula --N(R.sup.6)-- in which R.sup.6 represents a hydrogen atom, a lower alkyl group, a lower alkenyl group or a lower alkynyl group. There are also provided herbicidal compositions containing the derivatives and intermediates for preparing them. The compounds according to the present invention exhibit strong herbicidal activities and thus they are useful as active ingredients of agricultural chemicals.

    摘要: In an apparatus for molding resin to seal electronic parts, an internal die space defined at least by pots, cull portions, resin passages and cavities when an upper mold section and a lower mold section are closed, is cut off or sealed from the exterior atmosphere. Thereupon the die space is evacuated using a first evacuation by a vacuum source and a second or instantaneous evacuation by an instantaneous evacuation mechanism. The vacuum source for the first evacuation may be an active vacuum pump, while the instantaneous evacuation mechanism may be a vacuum tank that has been previously pumped down, for example. Using this apparatus, it is possible to quickly improve the degree of vacuum in the internal die space by efficiently and reliably discharging air, moisture and gas from the internal die space to the exterior due to a synergistic action of the evacuation and the instantaneous evacuation. Consequently, the formation of voids in resin molded members is prevented.
