Title: Cooling method for high temperature solution
Inventor: IEMORI NOBUMASA
IPC: F27D9/00
Filed: 1992-01-29
Abstract: PURPOSE:To prevent the occurrence of steam explosion even when a cooling jacket is damaged and perforating occurs by a method wherein the pressure of a liquid cooling medium is kept at a value lower than that of a high temperature solution when a high temperature solution is cooled through heat-exchange by using a liquid cooling medium. CONSTITUTION:In a cooling device, a cooling jacket 6 passing through a solution 7 to be cooled is disposed in a tub 8 containing the solution 7 to be cooled and through the flow of a cooling medium 4, sucked from a relay tank 5 with the aid of a drain pump 10, through the cooling jacket 6, the solution 7 to be cooled is cooled. A water level in the relay tank 5 is controlled by means of a level system 3 and a control valve 1 located in a cooling water feed pipe 2 so that a difference in a level between the relay tank and the drain pump 10 is adjusted to, for example, 3m. Operation of the drain pump 10 is controlled by monitoring the output of a pressure gauge 9 for detecting a water pressure in the cooling jacket 6 so that a water pressure in the cooling jacket 6 is kept at a value lower than the pressure of the high temperature solution 7. Even when perforating occurs to the jacket 6, a cooling medium is prevented from entering and the high temperature solution and steam explosion is prevented from occurring.

Title: Method for operating cooling facility of reactor well pool
Inventor: KONDO TAKAHISA
IPC: G21D1/00
Filed: 1988-02-22
Abstract: PURPOSE:To prevent the water temperature rise of a well pool by pouring part of the cooling water cooled by means of a heat exchanger for removing residual heat into a reactor well pool and fuel pool through an outlet side connecting line and part of fuel pool cooling system. CONSTITUTION:The reactor water branched to a heat exchanger 5a for removing residual heat is guided to an outlet side connecting line 28a on the other side through a by-pass line 13a after the water is cooled at the heat exchanger 5a. Therefore, part of the reactor water from a residual heat removing system A is again returned to a reactor pressure vessel 2 through the pouring line 15b of the Ab on one side and at the same time, poured into the downstream side of the filtrating and desalting device 26 of a fuel pool cooling system B through paired outlet side connecting lines 28a and 28b. The water poured into the downstream side of the device 26 is poured into a fuel pool 22 and reactor well pool 1 as the cooling water through part of the piping. Since a downward flow is produced in the reactor water around the reactor core 3 of the vessel 2 and rising flow is obstructed when the cooling water is poured, a rise in water temperature in the vicinity of the water surface is prevented.

Title: Permanent magnet type synchronous motor, and field controlling method therefor
Inventor: KUME TSUNEO
IPC: H02P27/06
Filed: 1993-02-01
Abstract: PURPOSE:To make it possible to extend a speed range to a high speed region without increasing the capacity of a drive inverter by causing a control current to flow through a control coil wound around a stator core in a high speed region, and by causing magnetic saturation in the stator core. CONSTITUTION:A control coil 4 and a yoke 5 are provided around the outer periphery of a stator core 11. Main magnetic flux 6 is usually formed by a magnetic pole 31, and a torque is generated by rotating magnetic fields caused by armature coils 2. When the control coil 4 is energized by direct currents, an auxiliary magnetic flux 7 is produced. The auxiliary magnetic flux 7 is at right angles to the main magnetic flux 6 that develops in the circumferential direction, and hence these fluxes never interfere with each other. However, when the auxiliary magnetic flux 7 is made larger, the stator core 11 causes magnetic saturation, thereby leading to the weakened main magnetic flux 6. Therefore, a torque T with respect to the same motor current is slightly reduced, but will not be sharply reduced. Compared with a conventional torque characteristic, the torque characteristic in a high speed range can be significantly improved.
