In the secure area, a plurality of pieces of security information used in a security process is stored. A security IPreads out a portion of the plurality of pieces of security information from the secure areaand stores it in the secure RAM. When the security information to be used in the security process is stored in the secure RAM, the security IPreads out the security information from the secure RAMand uses it.

Disclosed is an air gap measuring apparatus, for measuring width of an air gap formed between a rotator and a stator. An insertion section has a first flat plate section and a second flat plate section. Gap adjusting means drives the second flat plate section such that the second flat plate section moves away from the first flat plate section, until the first flat plate section and the second flat plate section abuts on the rotator and the stator. An operating section extends to outside of the insertion section, and operates the gap adjusting means. An elastic body has an end that follows the first flat plate section, and other end that follows the second flat plate section. A strain gage outputs electrical signals corresponding to the strain of the elastic body, the strain being formed due to the movement of the second flat plate section.

A wireless base station unit () monitors total transmission power, which is a sum of transmission power to all of mobile station terminals (-) connected for communication. When the total transmission power exceeds a first threshold value, which is a criterion for judging whether to reduce the transmission power or not, an upper limit value of the transmission power to the mobile station terminal at the lowest priority level is reduced by a prescribed quantity. When the total transmission power exceeds a second threshold value, which is larger than the first threshold value, communication connection with the mobile station terminal at the lowest priority level is cut.

A atomic beam generating method and apparatus for producing an atomic beam that is high in flow rate is disclosed which makes vacuum equipment simpler in construction, and is high in the rate of extraction of atoms, capable of adjusting its flow rate and applicable to many different atomic species. The atomic beam generating apparatus used produces a beam of atoms by extracting the atoms from a low temperature atomic cloud formed by laser cooling. The low temperature atomic cloud is formed by irradiating the atoms with at least two sets of laser lights in a region of laser beam intersection in which they intersect, each of the sets of laser lights being made of a pair of laser beams which are opposite in direction of travel to each other, the laser beams intersecting in the region of laser beam intersection. In this region of laser beam intersection there is provided a laser beam shading zone in which one of the laser beams in each of the sets of laser lights that is traveling in a particular direction is obstructed to provide a shade therefor. The laser beam shading zone is so located in the region of laser beam intersection that in the laser beam shading zone a force is brought about that is effective to force atoms in the laser beam shading zone to move towards a preselected direction, thereby forming a beam thereof.

A reactor water clean-up system is provided with a first filter demineralizer having a filter resin containing an alkali substance and a second filter demineralizer with a filter resin not containing an alkali substance. The reactor water is supplied to the first filter demineralizer during the term from the starting operation of the preoperating test of the nuclear reactor and of each fuel cycle to 2000 EFPH. The alkali substance contained in the filter resin is guided into the nuclear reactor to change the pH of the reactor water in the nuclear reactor to the weak alkali side. The Cr quantity which is taken in the oxide film of the fuel cladding tube surface is reduced. After 2000 EFPH from the starting operation, the supply of the reactor water to the first filter demineralizer is stopped, and then, the reactor water is supplied to the second filter demineralizer.
