Title: Fireproof spraying material
Inventor: SASAGAWA YUKIO
IPC: C04B28/06
Filed: 1988-08-15
Abstract: PURPOSE:To provide a fireproof spraying material having satisfactory quick- setting power, exhibiting high strength and causing a small rebound loss at the time of spraying by mixing alumina cement with a prescribed amt. of a compsn. obtd. by blending gypsum with ultraquick-hardening cement in a specified weight ratio. CONSTITUTION:A fireproof spraying material is produced by mixing 100 pts.wt. alumina cement with 1-50 pts.wt. compsn. consisting of gypsum and ultra-quick- hardening cement in (0.1-1):1 weight ratio. The alumina cement is produced by synthesizing clinker from an alumina source such as bauxite and a calcia source such as quick lime by calcining or electromelting and by pulverizing the clinker with a ball mil. When the fireproof spraying material is used, curing strength is improved because of a small rebound loss and such significant effects as to ensure a dense matrix and high calcining strength can be produced.

Title: Apparatus and method for pulverizing waste water
Inventor: SUZUKI TEI
IPC: C02F1/02
Filed: 1989-08-03
Abstract: PURPOSE:To stably operate a centrifugal membrane dryer without generating the differential pressure rise of a mist separator in the pulverization of radioactive filter sludge by arranging a tray having a large number of holes at a position where a condensate directly falls and providing a gap between the end edge part of the tray and the inner wall of the mist separator. CONSTITUTION:The condensed water supplied to a mist separator 2 flows down to a lower stage plate 6 from the gap 10 between a tray 8 having a large number of holes 4 to which condensed water directly falls and the inner wall of the mist separator 2. As a result, the amount of condensed water held on the tray 8 does not increase and no differential pressure rise is generated. Further, the decomposed gas dissolved in condensed water is diffused to a gaseous phase during a period when condensed water is stagnated until exceeds a weir. Therefore, the foaming phenomenon accompanied by the diffusion of the decomposed gas to the gaseous phase is never generated on the plate 6 under the uppermost stage tray 8.

Title: Deterioration diagnostic method for cable coating material
Inventor: KANEMITSUYA KAZUHIKO
IPC: G01N29/00
Filed: 1993-07-23
Abstract: PURPOSE:To provide a method for determining the extent of deterioration of cable coating material while laying the cable as it is without requiring any destructive sampling. CONSTITUTION:A probe P is applied to the outer peripheral surface of the coating material 12 of a cable 1 being laid and ultrasonic wave is transmitted from an ultrasonic transmitter S in the probe P toward the conductor 11 of the cable 1. The ultrasonic wave propagates through the coating material 12 and reflected on the conductor 11 before it is received by a receiver R. The velocity of ultrasonic wave propagating through the coating material 12 varies, as compared with that when the coating material is sound, according to the variation of breaking elongation due to deterioration of the coating material 12 and the variation corresponds to the extent of deterioration. Consequently, the extent of deterioration can be determined by determining the velocity of ultrasonic wave propagating through the coating material 12.

Title: Three-dimensional shaping method
Inventor: KANEMATSU TOSHIHIRO
IPC: B29C67/00
Filed: 1994-08-29
Abstract: PURPOSE: To accurately shape a shaped article having a desired shape within a short time by a method wherein a three-dimensional cross-sectional shape pattern is transferred to a shaping material in a planar state and the shaping material and a support material having physical properties different from those of the shaping material are stacked on a part other than the pattern in a laminar state and only the shaping material is fused and bonded. CONSTITUTION: Each cross-sectional shape pattern of a three-dimensional model is transferred to a shaping material 1 in a planar state and, after a support material 4 having physical properties different from those of the shaping material 1 is arranged on a part other than the cross-sectional shape pattern, the shaping material 1 and the support material 4 are stacked in a laminar state and only the shaping material 1 is fused and bonded to be shaped into a threedimensional shape.  Since two kinds of materials, that is, the shaping material 1 and the support material 4 having material quality different from that of the shaping material are laminated and only the shaping material 1 can be fused and bonded, the deformation during shaping can be made hard to generate by the support action of the support material 4 as compared with an optical shaping method using an ultraviolet curable resin and a complicated shaped article can be formed.

Abstract: PURPOSE:To enable manufacturing of an oxide fuel having a small discharging factor of FP gases by compression-molding a mixed powder of uranium dioxide and ceric oxide, and by reducing it in a reductive atmosphere after sintering in an oxidizing atmosphere. CONSTITUTION:At the first stage, uranium dioxide powder and ceric oxide powder are mechanically mixed together and then are added with a binder and compression-molded to produce so-called green pellet. At the second stage, the pellet is preliminarily sintered. At the third stage, the pellet is reduced at a temperature of 1,400 to 1,800 deg.C in a mixed gas flow of carbon dioxide and carbon monooxide. Cross-sectional structures of the UO2 pellet containing 1wt% of CeO2 and being manufactured in this way, and of another UO2 pellet manufactured in an ordinary way were observed with an optical microscope. As the result, there is no significant difference of diameters of crystaline particles between the pellets manufactured by this invented method and by conventional method. By using the former pellet like this, an FP gas discharging factor during a nuclear reactor operation can be well reduced.
