摘要： PURPOSE:To be able to make the re-starting operation of a whole pipe-line easy by only installing a clean water press-in mechanism in such a way that a clean water press-in tube is connected via a pump to a pipe line transferring coal and water slurry under pressure from a cleanwater source and at the re-starting operation time of highly concentrated coal and water slurry the slurry is enabled to flow effectively and easily by said mechanism. CONSTITUTION:During the normal operation time of a pipe line, a valve 5 is opened and a valve 8 is closed and a small-sized press-in pump 7 is stopped and when the flow in a piping tube 3 does not start even by the control operation of a main pressure transfer pump 2 at the re-starting operation time of highly viscous fluid, a very little amount of clean water from a cleanwater tank 6 is injected under pressure into the pipe 3 by the pump 7. In this case it is desirable that the valve is closed and the main pressure transfer pump 2 is stopped. It is possible that highly concentrated coal and water slurry may be slightly moved and if not, press-in clean water forms a clean water film between the inner wall surface of a pipe 10 as the piping tube 3 and the highly concentrated coal and water slurry 11, and flows mainly downward to make the flow of a whole slurry easy.

摘要： PURPOSE:To compensate for a load acting on the inner surface of a base bed slide guide so that frictional slide force can be set, by controlling pressurized air supplied to a plurality of static pressure pads having gaps for pressurized air flow in no contact with a slide guide surface. CONSTITUTION:Air for a static pressure pad is supplied from an air pressure source 1 through a pressure controlling valve 12 to an air supply groove 13. A workpiece 14 is mounted on a slide 3, and the weight Wt of slide 3, weight Ww of workpiece 14 and cutting force F or the like acting on the workpiece 14 work on a dynamic pressure slide surface as surface pressure and a floating force Fp acting on the static pressure supplied to the static pressure pad crbitrary floating force is obtained, so that the share of dynamic pressure slide surface and static pressure pad can be set at will according to load requirements only by supplying air pressure to set optional frictional force.

摘要： PURPOSE:To make it possible to measure the non-Newtonian property of the fluid flowing through a pipeline by an on-line system, by measuring the difference pressure of a different diameter pipe part having three different diameters and comparing the calculated difference pressure value of the different diameter pipe part with an actually measured difference pressure value. CONSTITUTION:Measuring pipes S, M, L different in an inner diameter are interposed on the way of a pipeline main pipe X and connected by reducers R so as not to inhibit the flow of a fluid. An operator 2 operates the output values from the difference pressure gauges mounted to the measuring pipes S, L on the basis of the output value from the difference pressure gauge 1M mounted to the measuring pipe M having the intermediate inner diameter supposing that the fluid flowing through the main pipe is a Newtonian fluid. The obtained operated values are inputted to differential amplifiers 3L, 3S where the differences between said values and the actually measured values from difference pressure gauges 1L, 1S are amplified and outputted. Said differences show the shift from the Newtonian fluids in the measuring pipes S, L and, if the magnitude or the positive and negative thereof is known, the non-Newtonian property of the fluid flowing through the pipe can be judged.

摘要： PURPOSE:To follow up a targeted track with high accuracy, by performing the correction of a command value so as to run over by the delay of a servo system at the termination of one moving process, and issuing a command to return to the middle point of the next process additionally, etc. CONSTITUTION:An axial control block in an NC digital servo in a discrete value system is constituted of an NC reader 1, an interpolation computing element 2, a comparison computing element 3, a servo amplifier 4, a motor 5, and a detector 6. And the method of a corrective arithmetic operation is executed in such a way that the correction of the command value is performed so as to run over by the delay of the servo system at the termination of one moving process and to return to the middle point of the next moving process is issued. Also, the correction of the command value to shift the next command start to the above middle point is performed. Thereby, it is possible to follow up servo output with high accuracy by applying a series of corrective operations on all of the commands with respect to the movement of a polygonal line.

摘要： PURPOSE:To prevent dilution, aggregation and dehydrated solidification of slurry by replacing the interior of a pipe line with wet air having the relative humidity higher than 80%. CONSTITUTION:A humidifying mechanism 8 and a fan means 9 are arranged immediately after a circulation pump 2. The humidifying mechanism 8 will produce wet air humidified over 85%RH which is pressure fed into a piping 3 by means of the fan means 9 to fill the entire length of the pipe line with wet air having the relative humidity higher than 80%. Thereafter, high concentration coal slurry is pressure fed from a tank 1 through a pressure feed pump 2 into the piping 3 to replace the wet air in the piping 3 in the direction of an arriving tank 6. Since contact of the wet air having the relative humidity higher than 80% against the high concentration slurry will never cause aggregation nor adhesion to the wall face, bad influence can be prevented when storing in a tank or utilizing combustion.
