Filed: 1984-01-27
Abstract: PURPOSE:To detect the contacting position accurately even when there is working liquid or working powder between measuring jig and work, by contacting the switch functioning rod of measuring jig against the work and opening/closing the switch through function of working rod. CONSTITUTION:In order to measure the position in vertical direction, a measuring jig 11 is lowered to contact the leading edge of operating rod 12 against a work 2 at point D. Since the operating rod 12 will not move at contacting time point, it will never cause mechanical contact while when lowering said jig 11 furthermore to bring the leading edge to point E, the mechanical contact will close to transmit a signal from the output end 11a through lead wire to contact confirming section. The stroke D-E of operating rod 12 from said contacting time point to close position of contact will be preliminary stroke of switch employing mechanical contact. Consequently, when presetting the vertical displacement required for preliminary stroke in the contact confirming section, the positional difference between actual contacting position D and close position E can be corrected.

Abstract: PURPOSE:To obtain deoxidized demineralized water to be used in an atomic power plant, etc. by passing oxygen-contg. demineralized water through an anion-exchange resin on which a hydrogen sulfite reducing redical, etc. is adsorbed, and then passing the water through a mixed-bed ion-exchange resin tower consisting of an H-and an OH-type resin. CONSTITUTION:Oxygen-contg. demineralized water is passed through an anion- exchange resin on which a reducing radical such as HSO<->3 and SO<2->3 is adsorbed to adsorb and remove the dissolved oxygen, and then passed through a mixed-bed ion-exchange resin tower consisting of an H- and an OH-type resin. Consequently, the oxygen is removed without consuming heat energy, etc., and the amt. of a waste liq. is remarkably reduced. The operation is also facilitated, and the impurities in minute amts. in a demineralized water tank can be removed. Besides, the apparatus is simplified and waste resin is not generated. Consequently, the spent demineralized water which has been discharged heretofore can be used without being discharged as the make-up water for a thermal electric power plant or an atomic power plant or the demineralized water for laboratories.
