Abstract: A stator for a rotating electric machine includes a stator core and a stator coil. The stator core is formed of a band-shaped steel sheet that is helically bent and laminated. The stator core has slots each opening at an inner periphery of the stator core and spaced from one another in a circumferential direction. The stator coil is formed of electrical conductor segments that are inserted in the slots of the stator core and connected with one another. The band-shaped steel sheet has slits each of which is formed, at a position corresponding to one of the slots, to be open to the corresponding slot. Each of the electrical conductor segments is substantially U-shaped and has a pair of leg portions respectively inserted in corresponding two of the slots of the stator core; the corresponding two slots are circumferentially apart from each other by two or more slot-pitches.

Abstract: A backup structure for an uprising pipe or a downfalling pipe of a vacuum degassing apparatus including the uprising pipe, a vacuum degassing vessel and the downfalling pipe, comprises the uprising pipe or the downfalling being made of platinum or a platinum alloy and having refractory bricks disposed therearound; and the refractory bricks having a thermal expansion relief member disposed on a top end thereof, the thermal expansion relief member comprising a material selected from a metal material and a ceramic material having a creep strength (JIS Z2271: 1993) of 35 MPa or above at 760° C.

Abstract: A backup structure for hollow tube made of platinum or a platinum alloy in which glass exudation from bricks employed for the backup is prevented, is provided and a vacuum degassing apparatus and a glass producing apparatus employing such a backup structure are provided.
