Filed: 1988-05-19
Abstract: PURPOSE:To reduce the eluted amount of constituent elements into the feed water from the tube of a heater and reduce the amount of formation of radioactive nucleus species in the reactor core by forming the tube of a heater of ferrite-based stainless steel which has been subjected to a bright annealing treatment. CONSTITUTION:The heater tubes 23 are constituted of ferrite-based stainless steel SUS 434. These heater tubes 2 use a cold-drawn seamless stainless steel pipe which was cold-rolled by a Pilger mill from a stock pipe. The intermediate annealing in the process of cold rolling and final annealing after finishing the rolling are not performed by the use of an atmosphere but in a reducing atmosphere of ammonia decomposition gases and bright annealing is performed. As for the kind of steel, SUS 434 is used and the annealing temperature is 780-782 deg.C, and the dew point of the ammonia decomposition gases for annealing is -30 deg.C. The cooling in the annealing is not by water cooling or rapid cooling but by slow cooling in the ammonia decomposition gases. The groove roll of the Pilger press machine has a high pitch and the mandrel abrasion number is in the range of Nos. 600-800 which is fine, and the pressing speed is 1/2 of the conventional speed. After machining the surface roughness of products through the bright annealing finish is indicated by maximum height (Pmax) which is 12.5 S.

Abstract: PROBLEM TO BE SOLVED: To provide the image processing device and method which can attain the satisfactory security for the image data that are stored in a memory. SOLUTION: A specific area of a hard disk where the copied image data are stored is confirmed (S401), and it is decided whether an erasion discontinuation request is inputted for the image data (S402). If the request is not inputted (NO), it is decided whether or not the disk includes an area to erase the image data (403). If the area is included in the disk (YES), the image data stored in one of areas where the image data should be erased are erased. Then the procedure returned to the processing of S402. The processing procedures of steps S402 to S404 are repeated until an erasion discontinuation request is inputted or no areas exist any more to erase the image data.

Title: Production of optical waveguide
Inventor: SAITO TATSUHIKO
IPC: G02B6/13
Filed: 1990-05-14
Abstract: PURPOSE:To reduce the light transmission loss by locally heating the optical waveguide forming part of a substrate glass to remove a dopant in this part. CONSTITUTION:The dopant which reduces the refractive index is allowed to penetrate a porous glass by contact to a solution including this dopant to produce a substrate glass 1 including the dopant, and this glass is made transparent by sintering. Thereafter, an optical waveguide forming part 3 of the substrate glass 1 is locally heated by irradiation of laser light 2 or the like to volatilize the dopant included in this part 3, and the dopant is removed from the glass substrate. In this case, the dopant which reduces the refractive index is removed by volatilization not to include the dopant in the locally heated part 3 of the glass. Thus, the refractive index in this part is made higher than that of the other part to reduce the light transmission loss due to Rayleigh scattering.
