If arc interruption occurs during AC arc welding, a first AC frequency predetermined for normal welding is switched to a second AC frequency higher than the first AC frequency. This allows the arc to be reignited without applying a high frequency high voltage, thereby preventing the damage of the surface of the weld bead or communication failure due to the high frequency high voltage.

摘要:
A toner cartridge includes a toner receptacle that houses toner, a plurality of stirring members housed in the toner receptacle, a plurality of gears meshing with each other on outside of the toner receptacle, and a phase display section. The stirring members are arranged next to each other in the toner receptacle and rotate to stir the toner. Each of the stirring members has a scraper that scrapes off the toner adhering to an inner surface of the toner receptacle. The gears rotate to rotate the stirring members in an interlocked manner with each other. The phase display section shows a meshing position of the gears so that the gears mesh with each other at a position where a phase difference along a rotating direction of the stirring members occurs between the scrapers of the stirring members that are next to each other.

An information recording medium includes a recording area for an auxiliary signal, and a recording area for a main signal. The auxiliary-signal recording area and the main-signal recording area are successively arranged. The main-signal recording area stores first information, second information, and third information. The first information represents plural tunes. The second information includes playback control information for separating the tunes into groups and implementing playback of the tunes group by group. The third information includes interactive data for permitting an access to the first information of the tunes group by group.

摘要:
In order to manufacture a CIS-based thin film solar cell that can achieve high photoelectric conversion efficiency by adding an alkali element to a light absorbing layer easily and with good controllability, a backside electrode layer (2) is formed on a substrate (1). Then, a p-type CIS-based light absorbing layer (3) is formed on backside electrode layer (2), and then an n-type transparent and electroconductive film (5) is formed on this p-type CIS-based light absorbing layer (3). At this time, the backside electrode layer (2) is constituted by forming a first electrode layer (21) using a backside electrode material in which an alkali metal is mixed and, then forming a second electrode layer (22) using the backside electrode material that does not substantially contain the alkali metal.
