Title: Reactor pressure vessel having forged nozzle
Inventor: DEIRITSUPU RAMANRA DESAI
IPC: G21C13/024
Filed: 1992-08-11
Abstract: PURPOSE: To attain sharp reduction of inspection cost through the whole lifetime of a nuclear reactor by forming a nozzle integrally with a cylindrical part of a cylindrical reactor pressure vessel(RPV) by forging. CONSTITUTION: A nozzle 46 of a power-driven cooling system is formed integrally with a cylindrical part 56 of RPV by forging, without welding. A protuberance 80 in the circumferential direction is formed in the cylindrical part 56 and the nozzle 46 by forging and this protuberance 80 constitutes a face whereon a support skirt part 48 is fitted with a skirt weld part 82 interposed. The support skirt part 48 has a skirt part 84 and a flange part 86 fitted to this part by a flange weld part 88. Although a considerable additional cost is required for forming the nozzle in the cylindrical part of the RPV by forging, it is offset substantially by the cost of inspection to be needed otherwise, since periodic inspection of a welded part is unnecessary according to this constitution, and sharp saving of the cost is enabled consequently through the whole lifetime of a nuclear reactor.

Title: Optical recording and reproducing device
Inventor: SAKAKI TERUO
IPC: G11B11/105
Filed: 1988-08-29
Abstract: PURPOSE:To branch a reflected light of a beam splitter further, to increase an apparent Kerr rotary angle and to improve the detection sensitivity and the S/N by arranging a thin plate made of a material having an optical isotropy so that an incident angle of a reflected light into a thin plate is a Brewster angle. CONSTITUTION:A thin plate 11 made of an optical isotropic material whose incident angle is set to be a Brewster angle iB is placed in a detecting optical path and the optical system is arranged so that a reflected light from a recording medium 5 is nearly S polarized light with respect to an incident face at that time. When a light passes through the thin plate 11, the S polarized light component is reduced by a transmissivity TS(=1-RS) and the P polarized light component is not reduced because of transmissivity TP=1. On the other hand, the reflected light is led to error signal detection systems 9, 10. The error signal detection systems 9, 10 obtain an error signal from a phase change and an intensity change in general, and the reflected light of the thin plate 11 is not subjected to phase change and only the intensity of the transmitted light is reduced, then the quality of the error signal is not deteriorated. Thus, the detection sensitivity and the S/N of the magneto-optical recording and reproducing device are improved especially.

CONSTITUTION:A computing means 4 of the concentration of powder dust to be measured, based on the measurement at a fixed point, determines the measured concentration of the powder dust to be monitored, at a fixed point, on the leeward side from a difference in the concentration of the powder dust between fixed points on the widward and leeward sides, being decided based on the measured values obtained by a powder dust measuring units 2 and an anemoscope-anemometer 3. A produced dust amount estimating means 5 calculates back and estimates a produced dust amount in a dust producing source from said measured concentration on the basis of a prescribed diffusion formula. An estimating means 6 of the concentration of the powder dust to be monitored estimates the concentration of the powder dust to be monitored, at an arbitrary point, from the estimated produced dust amount on the basis of the relationship in diffusion which is expressed by the diffusion formula having the particle size of the powder dust, a leeward distance, wind velocity, etc. as parameters. According to this method, the distribution of the concentration of the powder dust on the boundary of a site or the like can be made clear by the powder dust measuring units of a very small number.
