Abstract: PURPOSE:To make it possible to obtain the tensile force when a body under test is broken by providing an operating computer which receives the output signal of an amplifier for transmitting and receiving ultrasonic waves to and from a detector and operating moment acting on an earthquake isolation element. CONSTITUTION:An ultrasonic wave which is transmitted from an ultrasonic wave measuring device 23 is transmitted to the probe of a detector through a switch 22, propagated in a bolt 17, reflected and returned to the measuring device 23 again. When a tensile force is applied on the bolt 17, the speed of the ultrasonic wave which is transmitted in the bolt 17 back and forth is changed since the density in the bolt 17 is slightly changed. When the speed of the ultrasonic wave is measured, the tension of the bolt 17 can be converted. Then, the converted tension of the bolt 17 is sent into a computer 24 and stored in the computer 24. A signal for switching to the next detector is sent to the switch 22. This operation is repeated. In the computer 24, moment which is generated in an earthquake isolation element 2 is obtained based on the position of the bolt 17 that is keyed in beforehand and the tensile force of the bolt 17 which is sent form the measuring device 23.

Title: Method for recovering polluted material under ground surface
Inventor: ARATA TOMOCHIKA
IPC: B09C1/00
Filed: 1994-12-20
Abstract: PURPOSE: To decrease untreated parts where flow of air does not act and polluted materials are not recovered by relatively fluctuating the force for feeding the air and the force to suck out the air in the case where the air is fed into the ground to gasify the polluted materials in liquid strata and is sucked out together with these materials onto the ground surface. CONSTITUTION: While the air is first fed into a conduit 2 of an air injection well cylinder A by operating a variable type fan 4 thereof, a variable type vacuum pump 6 of a vacuum extraction well cylinder B is operated to suck the air out of this conduit 2 at the time of recovering the polluted materials under the ground surface. Namely, the air is delivered from air flow holes 2a through packing materials 3 for ventilation into the ground and is brought into contact with the polluted materials of a liquid phase to gasify these materials; thereafter, the air is sucked out together with these materials. At this time, the force to feed the air and the force to suck out the air are continuously or intermittently and relatively fluctuated. Namely, the pressure balance of both is broken by the relative fluctuation, by which the flow passages of the air in the ground are changed.  As a result, the untreated parts where flow of the air does not act and the polluted materials are not recovered are decreased.

The afore-said packing 1 is supported by an adapter 8 formed by a rubber ring so that an effect in preventing water from leaking from the casing 6 to the runner 7 is improved when the guide vane is fully closed. In this case, the packing 1a in U-shape is made of nitrile rubber so as to be concurrently formed in such a way that a gap in a triangular form formed between the guide vane shaft 2 and a bearing 5 may be eliminated. This constitution thereby improves durability against the rough surface of the sliding section of the guide vane shaft 2 caused by aging deterioration.
