A turbo-generator has a tapering cooling part positioned between a vapor turbine part and a generator part, and casings of these parts are combined together to form a sealed single-boundary structure. A turbine shaft in the vapor turbine part, a rotary shaft in the cooling part and a generator shaft in the generator part are combined unitarily and are supported by bearing parts in such a way that the unitary shaft does not pass from the boundary structure. The tapering cooling part has a smaller diameter at the side of the generator part, and the inner circumferential surface of the cooling part forms a labyrinth structure to separate the atmospheres of the vapor turbine part and the generator part.

Turbo-generator

Disclosed are a method of making a connection in a liquid and an apparatus therefor wherein a first connector having a protrusion at its front end is housed in a protecting tube which is open at its lower end and into which a gas is introduced, the protecting tube is filled with the gas so as to form a gaseous space therein within the liquid, a second container which is normally held within the liquid and which has a destructible plate at its upper end is exposed to the gaseous space, and the destructible plate is destroyed by the front end of said one connector so as to connector both connectors, whereby the connection in the liquid can be made without being affected by an ambient liquid.
