Abstract: Disclosed system specifies, based on measurement results of communication times taken for accessing a plurality of external databases, relation between the communication times taken for accessing the plurality of external databases, calculates, when accepting an instruction to execute processing using at least one of the plurality of external databases, a processing load when accessing the at least one of the external databases, based on the relation between the communication times, and controls an access to data included in the at least one of the external databases according to the calculated processing load.

Abstract: According to one embodiment, there is provided a white light source system including white light sources. An absolute value of a difference between (P(?)×V(?))/(P(?max1)×V(?max1)) and (B(?)×V(?))/(B(?max2)×V(?max2)) for each of the white light sources satisfies a relational expression represented by |((P(?)×V(?))/(P(?max1)×V(?max1))?(B(?)×V(?))/(B(?max2)×V(?max2))|?0.15 The white light source system has a light emission characteristic of white light emitted by the system is continuously changed along with an elapse of time by changing a mixing ratio of light beams from the white light sources.

Abstract: The object of the present invention is to provide a radioactive-ray image tube having less deformations, such as the twist of an input substrate, less aberration over the entire regions of an output image, excellent resolution and good brightness uniformity and contrast characteristics. This radioactive-ray image tube 1a comprises an input window 10 formed on one side surface of a vacuum vessel 2a and allowing radioactive-rays to enter the vacuum vessel 2a, an input screen 5 for converting the radioactive-rays incident on the input window 10 into a fluorescent image or a photoelectric image, and an input substrate 4a holding the input screen 5, is characterized in that the input substrate 4a comprises of a clad material 13 having an aluminum alloy material 11 on the radioactive-ray incidence side and a pure aluminum material 12 on the input screen 5 side provided integrally with each other.

Abstract: A wear-resistant and corrosion-resistant loom part comprises a Fe--Cr based alloy or a Fe--Cr--Ni based alloy, which has a substantially dual-phase structure comprising a ferrite phase and a martensite phase. The Fe--Cr based alloy preferably contains 10 to 20% by weight Cr, and contains 5 to 70 volume % of the ferrite phase in its structure. The Fe--Cr--Ni based alloy preferably contains 10 to 30% by weight of Cr, 0.01 to 15% by weight of Ni, and 5 to 70 volume % of the ferrite phase in its structure. The maximum crystal particle diameter of the Fe--Cr based alloy or the Fe--Cr--Ni based alloy is preferably 20 .mu.m or less. The loom part is preferably formed of either a dent of a reed or a heddle.
