摘要： PURPOSE:To make it possible to measure the physical quantity in a flowing place accurately and quantitatively even if the flow speed is high by intermittently casting laser light, which is expanded into a sheet shape, and tracking the tracer of a visualized image. CONSTITUTION:Laser light, which is expanded in a sheet shape, is intermittently cast on to fluid, wherein tracer particles (hereinafter particles) are mixed. The center of gravity of each particle is computed based on the recorded image information. The flowing path of the particle is tracked based on the center of gravity. Namely, a searching region B1 is set with the particle A1 in the first field selected at a time 1 as the center. When there is no second field image in the region B1, the particle A1 at a time 2 is arbitrarily determined. Then, a position S1 is estimated based on the relationship between the positions A1 and A2 and the emitting interval of the laser light. Then, a region B2 is set. When there is the particle A3 in the region B2, a position S2 at a time 4 is estimated based on the positions A2 and A3 and the emitting interval. Then, a region B3 is set. When there is the particle A4 in the region B,, the specified preset judgment is performed. When conditions are satisfied, the fact of the same particle is judged. The moving speed of the particle is determined based on the positions A1 and A and the distances and the times at the times 1 and 4.

摘要： PURPOSE:To simply visualize the flow field and to obtain the physical amount of the flow field quantitatively with good accuracy even when the flow speed is fast by casting laser beams into a fluid intermittently twice in specified seconds while spreading the laser beams into the form of a sheet. CONSTITUTION:Argon lasers 1 in the form of an optical sheet of, for example, 3mm or smaller thickness are intermittently cast into the area of the flow twice in one field of 1/60sec. The scattering light or fluorescent light of the argon lasers 1 cast to the particles is recorded by a camera 7 to a recording medium 8. The recorded data of the flow is divided, for example, into frame data of 1/30sec. to field data of 1/60sec. The shift of the scanning lines of the even-number fields and odd-number fields by the camera 7 and recording medium 8 is corrected. The locus of the particles in each field is operated from two particles of the shortest distance, and the correlation between the direction and size of the flow in the connecting fields is obtained. Accordingly, the flow area can be visualized at one time by relating the correlation with the locus of particles, and the speed of the fluid, stream function or the like physical properties can be obtained.

摘要： PURPOSE:To make the image of a particle into binary and highly precisely conduct the center-of-gravity calculation without having no influence of brightness level by determining the binary level of the particle image in proportion to the maximum picture element value of a picture element. CONSTITUTION:The particle of titanium oxide is mixed into a fluid in a vessel 2, and the scattered light or fluorescent light in a light surface 1A is photographed by a camera 3 from the direction orthogonal to a sheet and recorded in a picture recording device 4 by interlace system. Then, the recorded information is reproduced in the device 4, and picture-recorded in a frame memory 7 connected to a computer 6 so that the frame information has the same arrangement as the horizontal and vertical element numbers of the camera. The information recorded in the memory 7 is processed by the computer 6, the first time information is taken out, the memory information corresponding to the field information is left, and the information not corresponding to the field information is erased. The memory content corresponding to the information erased from the left information is interpolated. Then, the light density distribution is calculated from this information and made into binary at 1/4 of the maximum density, and the moment is calculated from this result to calculate the center of gravity of the particle.

摘要： PURPOSE:To prevent a film defect due to dust or seeding in a baking oven, in manufacturing a painted steel plate by a roll coater, by applying painting to the under surface of the steel plate under a specific range of tension and passing the painted steel plate through the baking oven. CONSTITUTION:In order to keep the contact pressure of a painted steel plate and coater rolls 1, 4 constant, for example, the tension of a deflector roll 3 and a bridle roll 8 to 0.5-3.0kg/mm . In this state, the paint from a paint pan 5 is applied to the lower surface of the steel plate 6 by an under surface coater roll 4 to form a top coat layer and service coat is subsequently applied to the upper surface of the steel plate 6. Because the steel plate 6 after painting is passed through a baking oven 7 in such a state that the top coat surface is turned down, the adhesion of dust or seeding falling from the wall of the oven to the surface of the paint film is prevented and a high quality painted steel plate having excellent film appearance is obtained.

摘要： PURPOSE:To execute always stably the uniform cooling of a metallic strip in the transverse direction thereof by providing plural cooling rolls having different crowns to a cooling zone and combining adequately the cooling rolls according to the form of the metallic strip in the transverse direction thereof. CONSTITUTION:The plural cooling rolls 7a-7g having different crowns are disposed in the cooling zone and the steel strip 1 is passed through a control device 3 for the strip temp. on the inlet side and is cooled by the rolls 7a-7g. The cooled roll is discharged from said zone. A steel strip form detector (thermometer for the transverse direction of the strip) 5 is disposed on the inlet side of the rolls 7a-7g to detect the form of the strip 1 in the transverse direction. The rolls 7a-7g are adequately combined to cool the strip 1 by a calculator 12 and a control device 11 according to the detected form, by which the strip 1 is cooled. The generation of the shape defect arising from the ununiform cooling in the transverse direction is thus prevented.

摘要： PURPOSE:To attain broad control power for cooling by adjusting the contact length at which a metallic strip contacts with cooling rolls and the number of rolls thereby controlling the contact area. CONSTITUTION:The cooling rolls 7a-7e are attached and detached to and from the metallic strip 1 in the stage of bringing the metallic strip 1 into contact with the rolls 7a-7e and cooling the same, by which the cooling is controlled. More specifically, the winding angle of the metallic strip 1 onto the individual rolls 7a-7e is adjusted in the case of changing the contact length of the strip 1 with the rolls 7a-7e in order to control the strip temp.to a target temp. A suitable number of the rolls 7a-7e are thoroughly detached from the strip 1 when the winding angle attains the limit. The cooling of the strip 1 is thus controlled without stopping the traveling thereof.

摘要： PURPOSE:To reduce the tension fluctuation of a steel strip during revolving, and to improve the treating capacity in coiling by reducing the time of revolution, by revolving a coiler itself at a specific speed, in coiling the strip by the coiler constituted of two vertically installed reels. CONSTITUTION:Two reels 2, 3 rotated by motors 5, 6 are attached to the main body 1 of a disk-shaped coiler. After coiling firstly a steel strip by the reel 2, a gear 7 engaged with the peripheral part of the body 1 is rotated by a motor 8 to revolve the body 1 by 180 deg. thereby the strip is coiled by the reel 3. In this case, a revolving speed pattern of the body 1 is converted into a rotating speed pattern expressed by an equation ( I ), by a sinusoidal wave, outputted from a function generator 12 actuated by a timer 13 or a revolving angle of the body 1, through a speed controlling circuit 11. Because the tension fluctuation of the strip, while the body 1 is revolved by 180 deg., is small, and also the body 1 can be remolved at high speed, the treating capacity in coiling is improved.
