Abstract: A soldering machine includes a solder vessel, an electromagnetic pump, and a nozzle. The solder vessel stores molten solder, and the electromagnetic pump moves the solder by generating electromagnetic force. The electromagnetic pump is submerged below the liquid surface of the solder. The nozzle ejects the solder in the solder vessel onto an object, such as a printed circuit board. Accordingly, the generated heat from the electromagnetic pump is conducted to the solder in the solder vessel, and the solder can be heated to a higher temperature than in the conventional soldering machine.

Abstract: During a software designing operation, a designer accesses a level prescribing unit through an interaction managing control unit. The level prescribing unit provides the guidance to specification information and design parts, etc. at a desired design level. If the designer selects and inputs specification information or design parts, the design editor corresponding to the design specification information in a design editor unit is activated, so that the designer is guided and aided through a display to produce a desired software. At this time, the information about the state of the editing operation "completed" or "not completed" is stored with the directory. The designed document satisfying a specific condition, for example, a document determined to be "design completed", is stored as a data base by a design data base storing unit.
