Filed: 1982-09-29
Abstract: PURPOSE:To enable to suitably alter the frequency and the voltage as well as the phase of a power source with less number of SCRs by sequentially producing the voltage from an AC power source by switching the phase. CONSTITUTION:When phase of f times power source is switched at every second in an N-phase AC power source of frequency f0, the frequency F of the basic wave of the output is represented by F=f/N-f0. Assume that the F is positive in the sequence of phases in case of f/N>f0, f/N<f0 is in reverse phase, and f/N=f0 becomes a direct current. When the outputs are produced in M sets, AC of M-phase can be generated with frequency F. The output voltage of the frequency converter can be altered simultaneously with the frequency by controlling the applied period of the voltage by switching the AC voltage of the other amplitude from the AC voltage of one amplitude in not only the conversion of the phase, but during the conversion of the phase, or between the phase conversion and the phase conversion.

Title: Vent controller for nuclear reactor container
Inventor: KUBOTA RYUJI
IPC: G21C9/004
Filed: 1987-07-13
Abstract: PURPOSE:To eliminate the expansion of an accident by a human operation error by automatically preventing the abnormal overpressure of a nuclear reactor container and the ignition of the gaseous hydrogen in the container. CONSTITUTION:A valve 11 is automatically opened when a detector 21 detects that the gaseous pressure in a pressure suppressing chamber 5 attains the threshold pressure of the nuclear reactor container 1. A bypass valve 12 is automatically opened as well when the pressure in the suppressing chamber 5 fails to drop down to the threshold pressure or below even after opening of the valve 11. The abnormal overpressure in the container 1 is thus surely prevented. The valve 11 is automatically shut when the drop of the pressure in a piping 16 down to the converted value or below is detected by a detector 22 after the pressure of a pressure gage 19 provided to the piping 16 attains the value obtd. by converting the fire propagation speed of gaseous hydrogen to a pressure or above after opening of the valve 11. The ignition of the gaseous hydrogen in the container by the combustion of an exhaust gas is, therefore, automatically prevented even in the event of an increase in the pressure of the container 1 by the gaseous hydrogen. The expansion of the accident by the human operating error is thus prevented.
