摘要： A preventive maintenance method and apparatus for a structural member in a reactor pressure vessel according to the present invention reduce a tensile residual stress on a surface of the structural member by impinging a water jet from a nozzle onto a plane surface of a deflector to thereby change direction of flow of the water jet, and impinging the water jet after being deflected onto the surface of the structural member. This method and apparatus are applicable to a narrow space portion, and can improve a residual stress on the surface of the structural member and can also prevent damage such as stress corrosion cracking.

摘要： The present invention relates to a WDM transmission system and the like suitable for optical communications between local stations having a relatively short repeater interval. In particular, the WDM transmission repeater employed in the WDM transmission system demultiplexes a plurality of signal lights propagating through a transmission line into first and second groups, takes out the second group, comprises a multiplexer for sending into the transmission line a new WDM signal group in which the first group thus demultiplexed and a third group of signal lights different from those of the first group are multiplexed, and has a special structure for reducing the influence of the not-demultiplexed crosstalk components within the second group upon the optical communications.

摘要： A method of treating a metal alkoxide solution to form metal oxide prepolymer molecules therein is characterized by irradiating the solution with light energy having a wavelength selected to break the metal-alkoxy group bond in said metal alkoxide, thereby to form the metal oxide prepolymer molecules in the solution. The prepolymer is converted into polymeric metal oxide gel. The stoichiometry of the oxide is high. A gel of carbon content below 4 atomic % can be achieved by the step of decarbonizing the gel, preferably using light to produce ozone.
