摘要： PROBLEM TO BE SOLVED: To provide an electrode catalyst having an excellent CO poisoning resistance. SOLUTION: Relation between CO poisoning resistance and quantity of oxygen contained in Pt-Ru alloy is noted. This is because a Pt-Ru alloy has a high affinity with oxygen and once the Pt-Ru alloy is in oxidized state, it is estimated that it is difficult to return to metallic state under PEFC operation conditions. When Pt and Ru are in the oxidized state, their electronic states may be changed, which will affect the properties of the catalyst. As a result of examination of the oxygen content in the electrode catalyst for a fuel cell on the effect of catalyst activity, it was found that CO poisoning resistance is improved if the oxygen content is less than 4.4mass%. Based on the findings, this electrode catalyst for a fuel cell has a carrier, and a catalyst layer having a Pt-Ru alloy carried by the carrier, with the oxygen content less than 4.4mass%.

摘要： PURPOSE:To prevent the adhesion of the spatter at the torch tip part and to increase the operation rate of a welding robot by cleaning the torch tip part by a shot blasting device on each one work stage. CONSTITUTION:A welding robot stops at the position of a shot blasting device 3 after completion of the welding of a work and the torch tip part 6 is inserted into the opening part 14 of the upper lid 13. In the cleaning stage, then, circuits 31, 34 become the circuit that compressed air is communicated by the operation of a changing valve 32 and the compressed air is exhausted from the nozzle pipe 15 just under the torch tip part 6. The shot ball 22 of the metallic small granule inside a case 12 is sucked to a nozzle cover 21 from the opening part 20 and spouted for the torch tip part 6 from the opening part 19 of the cover 21. The removal of the spatter adhered to the tip cover 28, tip 25 and core wire 26 of the torch tip part 6 is performed by the impact action of the shot ball 22. This spatters removal is performed repeatedly by the changeover of the circuit while under the welding stage.

摘要： PROBLEM TO BE SOLVED: To prevent the leakage of electric charge accumulated in a capacitor and to improve accuracy of the comparison result by short-circuiting the back gate of a well at the input terminal of an analog switch based on the decision result of a threshold error and switching an output terminal to the reference voltage or the power voltage from the input of an inverter. SOLUTION: A deciding inverter 42 having the same threrhold as an inverter 15 inputs the output voltage of a digital to analog converter 40 based on the digital signal which is produced in a comparator circuit 5 and then outputs the logical value of a high or low level. When the output logical value C of the inverter 42 is set at a low level, the MOS transistors TR 46 and 52 corresponding to a switch 31 switch the back gate of an N-channel MOS TR 24 toward the input side. Meanwhile, the MOS Th 44 and 51 corresponding to a switch 35 switch the back gate of P-channel MOS TR 23 toward the power voltage Vcc side when the output logical value C of the inverter 42 is set at a low level.
