Title: Sea water purification device
IPC: C02F9/00
Filed: 1992-04-03
Abstract: PURPOSE:To make it possible to visualize a watery scene in which saltwater fish swims in a natural environment with an invertebrate animal or a coral rock by arranging a nitrification module, a sterilization/algae extermination module with an ultraviolet beam lamp, an ejector and a denitrification module in the forced circulation flow route of an aquarium. CONSTITUTION:Water is forcibly circulated in an aquarium using a pump 2, and enters a nitrification module 4 filled with a mineral 3 based on a basic substance. As this mineral 3 has a large amount of oceanic nitrifying bacteria proliferating on the surface, so that ammonia excreated by fish is oxidized into nitric acid efficiently. The water thus rendered harmless is sterlized with the extermination of algae using a sterilization/algae extermination module 5 equipped with an ultraviolet beam lamp 6 capable of generating an ultraviolet beam dosage of more than 1.6X10<4>W.s/day. Further, air is supplied into the water using an ejector 7, passing through a pipe 8 and reaches the top of the aquarium. The water containing nitric acid enters a denitrification module 9 consisting of polymer beads 10 in which oceanic photosynthetic bacteria are collectively fixed, and returns to the aquarium 1 after nitric acid is removed from the water by the oceanic photosynthetic bacteria.

Title: Method for evaluating resistance against external scratch of optical fiber
Inventor: KOIDE TOSHIO
IPC: G01N3/08
Filed: 1991-03-20
Abstract: PURPOSE:To enable an accurate resistance against external scratch to be evaluated by allowing a uniform scratch to be formed easily by scratching using a scratch means of an optical fiber cutting device. CONSTITUTION:A film 12 of an optical fiber conductor 10 is partially eliminated by an organic solvent, thus enabling an optical fiber 14 to be exposed by approximately 50mm. By using the optical fiber cutting device and holding both edges of the exposed fiber 14 with clamps 26 and 28, a scratch 32 with a specified width and depth is provided on the fiber 14 at right angle to the fiber 14 by a cutting blade. The fiber including this scratch is pulled at a specified distortion speed and a pulling strength at the time of rupture is measured. Therefore, a uniform scratch can be given constantly when the fiber 14 is scratched by using the optical fiber cutting device in this manner, thus enabling resistance against external scratch to be evaluated accurately.

Title: Pulsation absorbing structure of flowmeter
Inventor: YAMASHITA TOMIISA
IPC: G01F1/66
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To accurately measure a flow rate by reducing influence of a pulsation flow by arranging flexible cylindrical members extending toward the downstream side from one of an inflow port and an outflow port. SOLUTION: In a flowmeter 10, cylindrical members 15 are installed toward the downstream side in an inflow port 12 and an outflow port 13 arranged in a main body 11. These cylindrical members 15 are formed in a cylindrical shape having a uniform thickness dimension by rubber having corrosion resistance to gas, elasticity and flexibility. In the cylindrical members 15, the partial diametrical expansion and deflection are not caused when gas normally flows toward the downstream side from the upstream side. For example, even if pulsation generated from a combustor propagates toward the main body 11, the pulsation does not propagate inside the main body 11 since the cylindrical member 15 of the outflow port 13 deflects, so that a measurement error can be reduced.  Even if the pulsation propagates toward the main body 11 from the upstream side of the flowmeter 10, the cylindrical member 15 of the inflow port 12 damps the pulsation while partially diametrically expanding toward the tip side from the base end side, so that a measurement error is not caused.

Abstract: PROBLEM TO BE SOLVED: To automate a work and to manufacture a sheet of stable good quality by sensing a resin amount between rolls, a sheet thickness and a roll opening/ closing position real time, calculating a roll operating amount at each object to be controlled, and simultaneously controlling all the objects. SOLUTION: CCD cameras 5, 5 are placed near right and left ends of a bank 1 between rolls 2 and 3, and CCD cameras 6, 6 are placed at right and left ends of a bank 8 between the rolls 3 and 4. Image data from the cameras 5, 6 are gray level image processed to obtain a bank size 21, and monitor displayed and graphically displayed. Regarding its thickness, each time scan data 22 is input from a thickness measuring instrument 17, and a mean thickness and a sheet width direction thickness distribution are similarly displayed. When a sensed value exceeds a set value or is predicted to exceed the value, the rolls are simultaneously controlled so that a suitable value is returned to each object to be controlled, and each bank sheet thickness is regulated. Thus, the sheet having no unevenness and stable quality can be automatically manufactured.
