摘要： PROBLEM TO BE SOLVED: To provide a simple concrete flaw detection method and its device easily usable in combination with an existing manual hammering technology. SOLUTION: A sound produced by hammering concrete is measured and analyzed, and a flaw is detected according to reduction in a frequency from a sound part. The reduction in the frequency is divided step by step into the sound part, an attention requiring part, and a repair requiring part for better usability. When a sound specific to the hammer is cut out by a filer, precision of the flaw detection is improved.

摘要： PROBLEM TO BE SOLVED: To solve the following problems about a conventional method: a system, wherein a heater is installed, is lacking in easiness of maintenance and inexpensiveness of a device; and a device is hard to constitute, due to the existence of a vertical rib and a horizontal rib, serving as a strength member of a track steel beam, when a hot-air type snow-melting system is to be applied to the track steel beam. SOLUTION: A duct is mounted inside the track steel beam in accordance with the arrangement of the strength member of the steel beam; a top surface of the duct is provided with an opening; and a hot-air heater is connected to the duct. The top surface of the duct serves as a traveling surface of the track steel beam. In such a constitution, the hot-air heaters are provided at both ends of the track steel beam, and connected to the duct. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a base isolator for pneumatic levitation, which is facilitated in practical use by reducing the occupying area of the whole base isolator including a feeder for compressed air and excellent in base isolating performance. SOLUTION: This base isolator is formed by providing an air jetting mechanism on the lower surface of a base isolation table, and taking an air jet receiving surface as an upper surface of an air feeder storing box. The air feeder is formed by a pressure air tank for storing the pressure air, an electromagnetic valve for feeding and interrupting pressure air, a regulator for regulating the pressure of the pressure air, an air pipe for connecting between them, and a vibration sensor. An earthquake wave is sensed, and opening and closing of the electromagnetic valve is controlled according to an electric signal to feed compressed air. The air pipe of the air feeder is connected to a coupling mounted on a top plate of the air feeder storing box to feed compressed air to a flexible tube and an air pad constituting the air jet mechanism, and the base isolation table connected to the air pad is floated by air to be isolated from vibration of an earthquake.
