摘要： PROBLEM TO BE SOLVED: To provide a nuclear reactor which eliminates the need for activities for monitoring the reactor in order to control the reactivity and requires no installations for controlling reactivity very minutely and responding to abnormalities in a reactivity controlling system.
SOLUTION: In-cassette cores 24 constituting fuel assemblies are provided in seven nuclear steam supply cassettes 21 laid out radially. In the in-cassette cores 24, the ratio of the quantity of loaded burnable poison contained in a core 24d in a peripheral cassette is higher than that in a core 24c in a central cassette so that the timing which makes it possible to keep the nuclear fission chain reaction in the core 24c in the central cassette and the core 24d in the peripheral cassette separately can vary. A control rod 32 is used as an installation in an emergency shutdown system of the reactor 20 and is kept fully pulled out upward during the normal operation of the reactor 20.

摘要： PROBLEM TO BE SOLVED: To obtain an incorporated video telephone set having high operability and capable of saving external connection wiring by providing the telephone set with a control means for holding the transmission of a moving image in response to a key input from an operation panel. SOLUTION: When a camera key on a key panel on the side of a video telephone A is depressed in order to execute image communication, a B2 channel is connected after a procedure based on a D channel. Check or the like related to terminal capacity is executed on the B2 channel, a picture signal is transferred from the video telephone A side to the video telephone B side and a picture is displayed on a display on the B side to execute sound/picture communication based on a moving image between the A and B. When a holding key is depressed, a holding tone based on a B1 channel and a holding picture based on the B2 channel are respectively sent to the opposite video telephone set. In the video telephone set having executed the holding operation outputs a holding tone to a receiver and outputs and displays the holding picture on a display part. When the holding key is depressed again in the state, the terminal is returned to the state held before the holding operation.
