摘要:
A coil for an electric rotating machine is configured with a conductor which is formed by bundling a plurality of square strands and stacking the square strands like a coil with Roebel transposition, mica tape which is wound a plurality of layers around an outer surface of the conductor and made up of mica paper and glass cloth backing, and an insulation wall formed by impregnating and curing resin between wound layers of the mica tape. Inorganic particles are supported with the glass cloth backing on the mica tape using an adhesive containing glue insoluble in the impregnated resin as an indispensable component.

The invention relates to an apparatus for demolishing a reactor shield wall. The apparatus has a pillar (2) extending from the top side of the reactor toward the bottom of the reactor, an upper support device (3) for supporting the upper portion of the pillar (2) at the top side of the reactor, and cutting devices (5, 6) mounted to the pillar so as to be upwardly and downwardly movable along the pillar (2). The pillar (2) is rotatably supported by the support device (3). The upper support device (3) has drive devices (30, 31, 32) for rotating the pillar (2). The cutting devices (5, 6) are caused to swing in the reactor interior by rotating the pillar (2). The drive devices are disposed at the top side of the reactor, and this permits easy maintenance and inspection.

The present invention is directed to novel 2,5-dichlorophenylthioglycolic acid derivative, a process for their production and a process for producing the desired product 2,5-dichlorophenylthioglycolic acid derived from said novel compounds. 2,5-dichlorophenylthioglycolic acid derivative of the present invention can be obtained by reacting 2,4,5-trichlorobenzensulfonates and thioglycolic acid in the presence of base, and said desired product can be obtained by desulfonating said compound in an aqueous solution of mineral acid. Novel 4-carboxymethylthio-2,5-dichlorobenzenesulfonates of the present invention can be used advantageously as an intermediate for the production of 2,5-dichlorophenylthioglycolic acid. The use of said intermediate makes it possible to obtain the desired product in a decreased process steps with high yield. In addition, it poses no problem of environmental pollution as pointed out with conventional methods because it uses no heavy metals.
