In the system, there is provided a unit for storing a table for correspondingly relating a plurality of alarm items to suppression reason items indicating that the display of the alarms can be suppressed. A generated alarm item and a generated event are specified by receiving the plurality of alarms and monitor information. A decision is made by reference to the table as to whether the generated alarm suppression reason item exists in the monitor information, the kind of generated alarm, and the generated event for each generated alarm item. An instruction is given to a display unit to suppress the display of alarms in which a decision is made that the suppression reason item exists.

Abstract: A laser light flux is divided and synthesized so that its light intensity distribution is changed from a Gaussian distribution to a non-Gaussian distribution. When a laser light flux having a Gaussian distribution is irradiated onto a dividing prism, it is divided into a left part and a right part which are refracted right and left inversely from each other. When the right and left parts are incident on a synthesizing prism, they are refracted again and travel to be overlapped with each other on a recording medium. The light intensity distribution on a segment at the apex of the synthesizing prism is weaker at the central part and stronger at the peripheral part. This is because the light fluxes resulting from the division are inverted in their position so that the central part of the Gaussian distribution is separated left and right while the peripheral part with a weaker light intensity is centered.

Abstract: The present invention employs as a recording medium a metal or alloy which exhibits an intercrystalline transition before and after writing. In the present invention, two light beams of unequal wavelengths are used so as to write information with the light beam of the longer wavelength and to erase information with the light beam of the shorter wavelength. In changing a written content, a wavelength with which the reflection rate of the recording medium increases is used.
