Abstract: This invention provides a process for easy and large-scale production of tubers from plants belonging to the genus Solanum, wherein the improvement resides in that tubers are formed with high efficiency by exposing stolons and shoots, elongated in a liquid phase under a carbon dioxide-applied condition during light periods in a shoot propagation step, to a gaseous phase in a subsequent tuber formation step, and that tubers are formed in a large number not only in a boundary medium surface area but also in a gaseous phase area distant from the medium surface by culturing the stolons and shoots during the tuber formation step in a culture jar with aeration of the gaseous phase. By employing such culture steps and conditions, tuber forming efficiency and quality of the produced tubers are improved.

Abstract: A method and apparatus for resistance welding in which, while both or one of the electrode center axes of a pair of opposing electrodes is inclined with respect to the electrode forcing axis, the electrode tip of the electrode is intermittently pivoted about the electrode center axis for welding. The contact between the electrode tip and workpiece is moved at a preset number of welds to define a next contact surface on the face of the electrode tip, and thus the number of welds (electrode tip life) is considerably improved.
