摘要： PROBLEM TO BE SOLVED: To produce a catalyst which is provided with a catalyst carrier having a high oxygen absorbing/releasing performance. SOLUTION: The catalyst having the high oxygen absorbing/releasing performance can be obtained by using, as the catalyst carrier, A 2 O 2 SO 4 (wherein A is a rare-earth element) obtained by firing a raw material being a sulfate of the rare-earth element in air at ≥800°C to decompose a part of the sulfate group. The catalyst carrier shown by the formula A 2 O 2 SO 4 changes into A 2 O 2 S in a reducing atmosphere of high temperature (≥ about 800°C) while releasing the absorbed oxygen to the outside. The A 2 O 2 S changes into the A 2 O 2 SO 4 in an oxidizing atmosphere while absorbing oxygen. COPYRIGHT: (C)2005,JPO&NCIPI

The electrode is characterized by having a temperature-sensitive material with physical properties varied according to temperature changes and with water permeable properties varied according to the temperature changes. That is to say, the water permeable properties of the electrode are made to vary by adding the temperature-sensitive material of which the physical properties are varied according to the temperature changes. A polymeric compound composed of an acrylamide, an acrylamide derivative, an acrylic acid and an acrylic acid derivative can be adopted as the temperature-sensitive material. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a power conversion device capable of performing a fail-safe operation with certainty.SOLUTION: When detecting that short circuit failures occur at a switching element TV1 in use of a power conversion device 10, a control device 50 turns off all switching elements of a 3-phase 3-level inverter. Thereafter, as shown in Fig. 2, the control device 50 turns off a third switching element TV3 of a V-phase 3-level inverter circuit part at which short circuit failures occur, and turns on a second switching element TV2 and a fourth switching element TV4. During that, the control device 50 makes first to fourth switching elements TU1-TU4 and TW1-TW4 of U-phase and W-phase 3-level inverter circuit parts at which short circuit failures do not occur be in an off state. Thereby, a wire between the first switching element TV1 and an output point OV are fused.
