An oxide superconductor comprises a composition represented by the composition formula: (Nd.sub.x --Ce.sub.y --L.sub.z).sub.2 CuO.sub.4-d (wherein L is an element selected from Ca and Mg, and x+y+z=1). The compositions of Nd, Ce and L of the oxide superconductor corresponds to a point falling inside an area of Nd--Ce--L ternary diagram surrounded by straight lines (A-B), (B-C), (C-D) and (D-A) connecting point (A) with point (B), point (B) with point (C), point (C) with point (D) and point (D) with point (A), respectively, the points (A), (B), (C) and (D) being points (x=1, y=0, z=0), (x=0.4, y=0.6, z=0), (x=0.4, y=0.3, z=0.3) and (x=0.1, y=0, z=0.9), respectively, in the Nd--Ce--L ternary diagram. Above-described Nd--Ce--L--Cu--O oxides can exhibit superconductivity within a wide range of composition when heat-treated in an atmosphere of nitrogen.

A mechanical-puffer-type arc-extinguishing chamber includes a fixed main contact, a movable main contact that moves on an opening-and-closing axis in a connectable and disconnectable manner to and from the fixed main contact, and a mechanical puffer chamber that is provided in the movable main contact and blows compressed insulation gas to an arc. A thermal-puffer-type arc-extinguishing chamber includes a fixed contact, a movable contact that moves on the opening-and-closing axis in a connectable and disconnectable manner to and from the fixed contact, and a thermal puffer chamber in which compressed insulation gas is blown to the arc. The mechanical-puffer-type arc-extinguishing chamber and the thermal-puffer-type arc-extinguishing chamber are arranged in series on the opening-and-closing axis, and two breaking portions are electrically connected in series.

A controller device is used for more information processes. The controller device is capable of wirelessly communicating with an information processing device. The controller device includes a communication unit, a display unit, and a program executing unit. The communication unit transmits, to the information processing device, operation data obtained based on an operation performed on the controller device, and receives, from the information processing device, image data generated in the information processing device through a process performed based on operation data. A display unit displays an image represented by the image data received from the information processing device. When a predetermined operation on the controller device is performed, the program executing unit executes a predetermined program and displays at least the image resulting from the execution of the program on the display unit. The communication unit transmits, to the information processing device, data indicating that the predetermined program is being executed.
