    摘要： A nuclear reactor of the type which uses liquid metal as primary and secondary coolants, and wherein the reactor vessel contains a core and a plurality of vertically extending cylindrical intermediate heat exchangers for carrying out heat exchange between the primary and secondary coolants; primary coolant circulation pumps disposed outside of the reactor vessel; a pipe for conducting to the circulation pump the primary coolant which has passed through the intermediate heat exchangers after leaving the core; and a pipe for guiding the primary coolant discharged from the circulation pump to the core through the reactor vessel.

    摘要： A magnetic recording apparatus has a rotating drum which rotates magnetic heads at a constant speed. The magnetic heads scan a magnetic tape. On a magnetic tape, an area written by each scan always includes a lateral portion of an area written by the previous scan. In this portion, old data is overwritten by new data, and writing continues. An area excluding the overwritten portion is a recording track. The running speed of the magnetic tape is changed by a system controller, and hence the recording track width can be changed.
