A building safety verification system and a building safety verification method for estimating a degree of damage of a building after an earthquake occurs are provided. The building safety verification system includes: an inter-story displacement measurement unit which obtains, from measurement data of acceleration sensors which measure accelerations of a plurality of stories in a building, an inter-story displacement of each of the stories; a natural period measurement unit which obtains a natural period of microtremor of the building from measurement data of a micro vibration sensor which measures micro vibration of a highest story of the building or a story near the highest story; and a building safety evaluation unit which evaluates soundness of the building from the inter-story displacement obtained by the inter-story displacement measurement unit and the natural period obtained by the natural period measurement unit.

Building safety verification system and building safety verification method

A method for manufacturing a printed circuit board assembled panel by a simple process with an excellent material yield and a high conforming product rate. Unit printed circuit boards previously manufactured are arranged in a frame in a prescribed relationship. Then, the printed circuit boards are fixed to one another, and the printed circuit board and the frame body are fixed to one another.

A rigid-flexible board and a method for manufacturing the same can be provided, whereby the material yield ratio can be enhanced and the productive yield can be also enhanced. A rigid board with a step for connection and a flexible board with a connector at the edge thereof are formed independently. Then, the connecting area is spot facing processed so that the depth of the thus obtained depressed portion is equal to or lower than the thickness of the flexible board. The connector of the flexible board is electrically connected to the vertical wiring area of the depressed portion.
