    摘要: A non-oriented electrical steel sheet having a high magnetic flux density in a rolling direction of the steel sheet is produced by hot rolling a raw steel material including C: not more than 0.03 mass %, Si: not more than 4 mass %, Mn: 0.03˜3 mass %, Al: not more than 3 mass %, S: not more than 0.005 mass %, N: not more than 0.005 mass % and the balance being Fe and inevitable impurities, and then cold rolling and finishing annealing to produce a non-oriented electrical steel sheet, characterized in that a crystal grain size before the cold rolling is rendered into not more than 100 μM and the finishing annealing is conducted by rapidly heating up to a temperature exceeding recrystallization temperature at an average temperature rising rate of not less than 100° C./sec.

    摘要: A gas-insulated bushing including an insulating tube filled with an insulating gas, a central conductor centrally arranged within the insulating tube, and a capacitor unit connected to the central conductor and partitioning the interior of the insulating tube. The central conductor has an intermediate constriction to which the capacitor unit is connected and is formed of two connected conductor parts, at least one of which is terminally restricted to form the constriction. A pair of flanges is secured to the ends of respective of the conductor parts and connects the conductor parts at the constriction. A shield member is supported on one of the flanges and spaced apart from the conductor parts at the constriction in order to relieve the electric field at the constriction.
