摘要： PROBLEM TO BE SOLVED: To remove not only a ferrite fine particles containing-product but also a nonmagnetic material fine particles containing-product by leading floating residue flowing along the pipe wall side in a water pipe to a prescribed place and accumulating and flocculating the led floating reside to take out it to the outside. SOLUTION: Floating residue flowing at a fixed flow rate in a water pipe 1 is made to flow along the pipe wall side in a water pipe 2 by the Coanda effect due to a vortex generated in a vortex generating pipe 6, and furthermore, this floating residue is made to flow along the pipe wall by action by magnetic field applying means 11 and 11', and nonmagnetic residue fine particles not drawn near by a magnetic field receives centrifugal force by the vortex to make then to flow along the pipe wall. Successively, the floating residue is separated to lead it to a bypass pipe 5, and the led floating residue is caught by a magnetic field applying means 13 and is accumulated and flocculated in a drain 9 to take out it to the outside from a takeoff port 10.

摘要： PROBLEM TO BE SOLVED: To obtain an inside-of-conduit diagnostic apparatus whose structure is simple, by which a defect on the inside wall of a long pipe is detected and in which a parachute is not projected inside a photographed image by a method wherein illumination light is supplied to a wall surface inside a conduit, reflected light from the whole circumference is received so as to be image-formed as an image without a gap the image is transmitted by an image transmission means. SOLUTION: An inside-of-conduit diagnostic apparatus is provided with a light-receiving means as a conical prism 63, and with an image formation lens 31 which forms an image at a bundle-type image fiber 36. It is constituted of an image fiber as a transmission means around it and of a bundle fiber 64 for illumination light. A parachute 52 is attached so as to be freely rotatable, and a force in an advance direction and a turning force are generated by a whirling flow inside a pipe. The image of a flaw or the like existing on a pipe wall is incident on the conical prism 63, it is totally reflected by an opposite slope, it is incident on the image formation lens 31 at the image fiber 64, and it is image-formed on the end face of the bundle-type image fiber 36 so as to be transmitted. A beam of light which is transmitted through the fiber 64 which is arranged in a multilayer concentric shape on the outer circumference of the image fiber 36 is reflected by the slope of the prism 63 equally to the incident light so as to irradiate an imaging range.

摘要： PROBLEM TO BE SOLVED: To suppress the vibration of a sensor for diagnosis, reduce the friction between an image transmission cord and the wall in a pipe, and to achieve a stable and accurate diagnosis, by sending a diagnosing device into the pipeline by means of an intermittent fluid or a spiral flow fluid. SOLUTION: A compressed air is supplied to an inlet unit 3 via an annular Coanda slit 4, thus generating a Coanda spiral flow. An image transmission code 7 and an image sensor 5 for diagnosis at the tip are inserted into a pipeline while vibration and friction with the inner wall of the pipeline are small due to the Coanda spiral flow fluid flow generated in a flexible hose 2 and the pipeline 1, thus diagnosing the pipeline at a required position. An inclination surface 9 where a diameter is reduced toward a connection part 8 is formed near a Coanda slit 4 of the inlet unit 3. A spiral flow is formed by the inclination surface 9 and an image transmission cord 7 is guided by a negative pressure suction force generated at an introduction port 6.

摘要： PROBLEM TO BE SOLVED: To provide a stable plasma flow with little turbulence which is converged to the blowout axis by making a current flow to a high frequency coil, and making a spiral flow passing a gradually contracted tube part into a plasma. SOLUTION: An inert gas is supplied from a gas feed port 6, and the gas is blown out through an annular Coanda slit part 3. The angle θ of an inclined surface 3 is set to 5-70 deg., whereby a Coanda spiral flow which is one kind of turning flows is formed in the process of passing in a gradually contracted tube part 7 to develop a strong negative pressure sucking force in a suction port 2, and the spiral flow is consequently sucked into a device through the suction port 2 by the negative pressure sucking force. Further, the current is made to flow to a high frequency coil 8 wound on the outer wall of the gradually contracted tube part 7 to make the spiral flow passing the gradually contracted tube part 7 into a plasma. Thus, the plasma flow containing this turning spectrum component is converted to the blowout axis, and further forms a stable plasma flow with little turbulence.

摘要： PROBLEM TO BE SOLVED: To disperse and mix powder in a liquid by sucking the powder from a supply opening part to supply to a nozzle by negative pressure generated in the supply opening part side by the introduction of a compressed fluid from an annular slit and jetting a mixed phase spiral flow composed of the compressed fluid and the powder. SOLUTION: The spiral flow is generated by jetting the compressed fluid from the annular slit 13 to the inside of the nozzle and accordingly the negative pressure is generated at the supply opening part 11 side. Then, the powder is sucked and supplied from the supply opening part 11 by utilizing the negative pressure. And the powder is dispersed by the spiral flow generated in the nozzle and the mixed phase spiral flow is charged into the liquid by covering the periphery with the spiral flow generated by the compressed fluid from a poststage spiral nozzle 2 and forming a centralized flow in the pipe axis center, which is peculiar to spiral flow. Then, the powder is swirled and stirred by the spiral flow and is dispersed and mixed in the liquid.

摘要： PROBLEM TO BE SOLVED: To shorten a stand-off distance and to enable an efficient surface treatment such as washing and cutting by mixing a liquefied gas with a high pressure liq. and ejecting the mixture. SOLUTION: The liquefied gas becoming a liq. or a solid under high pressure is mixed with the high pressure liq. and ejected from a nozzle. The liquefied gas is momentarily expanded in volume and the gas is converted to a droplet, and also a high efficiency surface treatment such as washing, cutting and grinding become possible by realizing a short stand-off distance, the removal of compression heat and the controlling of a liq. amount. A relation between the stand-off distance and impact pressure in the device using a conical nozzle and a cylindrical nozzle is shown. Pressurized water is used as the high pressure liq. and a gaseous nitrogen is used as the liquefied gas. The impact pressure is raised when both of a two-phase jet stream conical nozzle A and a two-phase jet stream cylindrical nozzle B are subjected to respective comparison with a case of a single-phase jet stream conical nozzle (a) and a single-phase jet stream cylindrical nozzle (b).

摘要： PROBLEM TO BE SOLVED: To stabilize chucking force by a Bernoulli's effect, suppress disturbance caused by initial jet, and furthermore restrain operating environment from being deteriorated. SOLUTION: Both the negative pressure suction part of a Coanda spiral nozzle acting as a fluid suction port and Coanda nozzles acting as a fluid injection port, are disposed to a chuck head at the tip end of an arm, and chucking force is thereby generated by means of Bernoulli's effect produced when let fluid be injected out of the Coanda nozzles by means of a Coanda effect at the time of being moved to the Coanda spiral nozzle for sucking, so that a held body is thereby held so as to be moved in a non-contact manner.

摘要： PROBLEM TO BE SOLVED: To make the item indicating tag applicable even to the items in high deformation freedom such as articles of clothing, items liable to such as rental or cleaning articles by making the tag feasible of writing-in and reading-out of data using a magnetic head. SOLUTION: For example, U-shaped magnetic bodies are discontinuously jaxtaposed between a top face 3 and a bottom face 4 forming a film or sheet on a magnetic recording medium 1 looking like a film or sheet so as to form a closed magnetic path for making feasible of the writing-in from one side. On the other hand, as for the reading-out, the medium 1 in magnetic sensor mode enabling the magnetism to be discriminated can compose two bits. In such a composition for an example, the item indicating tag feasible of writing-in and reading out different from the conventional POS bar code system can be applied even to the articles of clothing in large size apt to deform or rental items using the tag apt to stain further making feasible of both writing-in and reading-out.
