Title: Treating method for nitrogen-containing wastewater
Inventor: TAKASHIMA YUJI
IPC: C02F1/42
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To keep a stable treatment over a long period of time by preventing the scale generation in a treating device or a catalyst which is used in removing ammonia nitrogen from wastewater containing both ammonia nitrogen and hardness components (Ca, Mg) with an ammonia stripping method or a catalytic oxidation method, and to reduce the costs by decreasing a maintenance frequency of the treating device or catalyst. SOLUTION: Wastewater 2 in which ammonia nitrogen coexists with hardness components is brought into contact with a cation exchange resin columns 4 and 6 to remove the hardness components contained in the wastewater. Subsequently, the wastewater is treated with an ammonia nitrogen removing device 28 employing an ammonia stripping method or a catalytic oxidation method to remove the ammonia nitrogen. It is desirable to use a weak acid cation exchange resin as the cation exchange resin.
Patent JP-H02277604-A (JP)
Title: Nozzle for molding machine
Inventor: FUKUDA TAKESHI
IPC: B28B1/24
Filed: 1989-04-20
Abstract: PURPOSE:To obtain excellent durability, heat insulation, high strength and high toughness by constituting a nozzle main body of partially stabilized zirconia and fitting an annular fitting made of metal to the outer circumference thereof and allowing the clamping external pressure exerted from the annular fitting to act on the internal pressure caused in the nozzle main body which is allowed to act when the kneaded material is fluidized. CONSTITUTION:A nozzle 10 is constituted of both a nozzle main body 11 made of PSZ and an annular fitting 12 made of cast steel. The nozzle main body 11 is formed into a nearly truncated cone shape and an injection hole 13 is penetrated which passes the kneaded material in the central axial direction. Further a truncated cone-shaped conical surface 17 is formed to the outer circumferential face of the nozzle main body 11. A fitting 12 made of cast steel is fitted to the outer circumference thereof. When injection pressure allowed to act on the nozzle main body 11 is increased at a time of molding, the expansion force exerted outward from the inside of the injection hole is caused in the nozzle main body 11 but clamping force is exerted in the inner direction of diameter from the fitting 12. Therefore the strain of the nozzle main body 11 made of PSZ is reduced and brittle fracture is made difficult to be caused. Furthermore breakage, a cutout and a crack of the nozzle resulting from impact, etc., exerted from the outside are prevented.

IPC: B65D25/52
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To provide an adhering method for a packaging container made of a cardboard and a lid thereof, which prevents a gray-colored wastepaper layer from appearing after unsealing the container. SOLUTION: This adhering method for a lid, in which a lid 10 is allowed to adhere to a container main body 8 of a packaging container 2 made of a cardboard having a white-colored surface layer on a front face side and a wastepaper layer on a rear face side, includes a step of applying an adhesive 32 to a predetermined portion 30 on the rear face of the lid 10 to make it permeate through the wastepaper layer at this portion 30, a step of allowing the lid 10 to adhere to an adhesion area 34 of the container main body 8 with the adhesive 32, and a step of determining an area of the adhesion area 34 so as to be releasable at the surface layer in the adhesion area 34 when the lid 10 in an adhesive state is unsealed.  In the packaging container made by this method, the wastepaper layer of the lid 10 is not released when the container is unsealed, because the wastepaper layer of the lid 10 is solidified as a continuous layer by the adhesive 32. Further the release on the side of the container main body 8 is also effected at the surface layer, so that the gray- colored wastepaper layer does not appear.
