Abstract: A one-side submerged arc welding method includes joining two steel plates butted to each other by submerged arc welding from one side using a plurality of electrodes. During the submerged arc welding, at least one of the electrode distances between adjacent electrodes in a terminal end region of the steel plates is changed.

Abstract: A microencapsulated curing agent for use in curing a thermosetting resin is provided. The microencapsulated curing agent includes an organic peroxide curing agent and a polyurethane resin encapsulating the organic peroxide curing agent. The microencapsulated curing agent, when heated to 100° C. for 30 minutes, exhibits a loss of weight of no greater than 10 wt. %. Additionally, when heated to 140° C. for 5 minutes, the microencapsulated curing agent exhibits a loss of weight of at least 4 wt. %.

Abstract: A curing agent for unsaturated polyester resins is made by microencapsulating an organic peroxide curing agent in a polyurethane protective coating or shell.

Abstract: A microcapsule which is able to stably retain a benefit agent such as a volatile substance for an extended period, and which is also suitable for encapsulating fragrances and the like. Such capsule encapsulates a mixture comprising a volatile substance, and an additive that has a higher melting point than the volatile substance and is able to undergo mutual dissolution with the volatile substance, wherein the mixture exhibits a melting point range, and a portion of, or all of, that melting point range falls within a range from ?20 to 60° C. The present invention also relates to consumer products including cleaning and/or treatment compositions comprising such microcapsules, and processes of making and using same.
