A nuclear power plant building includes a building body portion and a roof covering over the building body portion. The building body portion is formed in a rectangular shape in plane cross section by four outer walls. The roof is of a shell construction. In addition, corner walls each to bridge between the adjacent outer walls or to bridge between the roof and the outer wall are provided at angle portions of the body portion of the building.

In the case where, e.g., because of provision of a high-gain and high-energy Q-switched laser oscillator in a laser system in a MOPA configuration, the duration &#x3c4;z from the time point when oscillation-stage Q switches (and) start the gate ON to the time point when a pulse laser beam () starts to grow is shorter than the fall time &#x3c4;f of amplification-stage Q switches (,, and), by implementing control in such a way that the gate-ON timing of the oscillation-stage Q switches (and) lag behind the gate-ON timing of the amplification-stage Q switches (,, and) by a predetermined time, the loss in the pulse laser beam () at the amplification-stage Q switches (,, and) can be prevented, while the gain deterioration due to a spontaneously amplified ray () produced in the amplification stage is being suppressed. Therefore, a high-energy pulse laser beam can efficiently be obtained.

A corner member for a front-loading poster or picture frame is disclosed. The corner members are assembled between adjacent frame sections which have rotating cover members hingedly attached to base members. One or more raised protrusions or ridges are provided on the surfaces of the corner members adjacent the frame sections in order to provide improved manufacturing, assembly and operation of the frame. The raised ridges keep the cover members centered between the corner members and eliminate binding during opening and closing of the frame sections.
