A gas reclaiming equipment capable of separating SFgas from a mixed gas efficiently and shortening reclaiming work under reduced pressure. A gas separation equipment is provided between a gas insulated equipment and a gas liquefaction system. The gas separation equipment separates nitrogen gas from the mixed gas, and concentrates SF6 gas. Only SFgas is sent into the gas liquefaction system. The gas separation equipment uses pressure swing adsorption using an adsorbent with selective adsorption. Moreover, a buffer tank for storing mixed gas is provided between the gas separation equipment and the gas insulated equipment. The buffer tank and the gas liquefaction system are connected by a reflux-line. The reflux-line refluxes the gas in a gas phase in the gas liquefaction system to the buffer tank. Furthermore, the gas separation equipment is connected to a storage tank. The storage tank accumulates the nitrogen gas separated with the gas separation equipment. The adsorbent to adsorb SFgas is enclosed in the storage tank for exhaust gas. To absorb decomposed gas, the filter has an adsorbent of the chemisorption type. The adsorbent has of a metal hydrate.

A stator for a dynamoelectric machine includes an annular stator core composed of a developed core formed by stacking a number of steel sheets, each steel sheet including a plurality of unit cores each of which includes a unit yoke and a magnetic pole tooth and which are sequentially connected together by connecting portions integral with the respective unit yokes, and a stator coil wound on the magnetic pole teeth. Each unit yoke has a circumferential end overlapping, in a direction of stacking of the steel sheets, a circumferential end of the unit yoke adjacent to said each unit yoke.
