Inventor: SAMUSON HETSUTEIARACHICHI
IPC: G21C19/307
Filed: 1995-03-02
Abstract: PURPOSE: To reduce the start and development of crack at the surface of a metallic constituent of a water-cooled nuclear reactor or related equipment by injecting the solution of compounds containing noble metal into the water of the nuclear reactor. CONSTITUTION: This method is a field technique by which the inside of a crack in the surface of the constituent part of a nuclear reactor is coated or doped with a noble metal by injecting the solution of compounds containing a noble metal such as palladium into the inside of the high-temperature water of the nuclear reactor. In the nuclear reactor, feed water is fed into the pressure vessel 10 through a feed- water inlet 12 and a feed-water sparger 14. The solution of the noble metal compounds is preferably injected at the upstream point of the feed-water inlet 12. The high- temperature inside the core 20 and the radiation of gamma-rays and neutrons act so as to dissolve the compounds of the noble metal.  Thereby, the ions or atoms of the noble metal become free and adhere to the circumference of the opening part of the crack and the inside thereof at the surface of the oxide film of the metallic constituent part. Thus, the growth of crack can be restrained.

Title: Compacting treatment method of oxide film
Inventor: SHIMIZU AKINORI
IPC: H01L21/316
Filed: 1983-03-15
Abstract: PURPOSE:To increase the density of an oxide film and decrease pin holes, and to improve reliability by annealing the oxide film applied onto a semiconductor base body in an oxidizing atmosphere. CONSTITUTION:An oxide film applied onto the surface of a semiconductor base body through methods except thermal oxidation is thermally treated in a high- temperature oxidizing atmosphere. For example, the upper section of a silicon board is coated with a silicon oxide film through a CVD method using silane and O2 as raw material gases, and the silicon oxide film is thermally treated for 30min in a dried O2 atmosphere at 900 deg.C. Consequently, the number of pin holes in the CVD silicon oxide film decreases by approximately one figure. On the other hand, density increases in the same manner as annealing in a conventional inactive atmosphere. It is preferable that a CO atmosphere or an NO atmosphere besides an O2 atmosphere at 500 deg.C or more is used as the high- temperature oxidizing atmosphere.

Abstract: PURPOSE:To reduce the size and cost of a recorder by using plastic materials to form 1st and 2nd ftheta lenses disposed successively from a deflection scanning means on an optical path of light to be guided on a recording medium, thereby constituting an ftheta lens system. CONSTITUTION:The ftheta lens system 126 consisting of the 1st and 2nd ftheta lenses 102, 124 and 1st and 2nd mirrors 128, 130 are provided in a case 82.

Abstract: PURPOSE:To accurately estimate the component concns. of Mn and P in a molten steel at the end of blowing by using the analysis values of the Mn and P determined by sampling during converter blowing and the quantity of the non-decarburizing oxygen from the point of the time when the sample is drawn before the end of the blowing. CONSTITUTION:The sample is drawn by a sublance during blowing of the converter and the analysis values of the Mn and P at the time of the sampling are determined. Of the oxygen quantity supplied from the point of the time when the sample is drawn before the end of the blowing, the quantity of the non-decarburizing oxygen which is not used at the end of the blowing is determined. The sampling is preferably executed about 1.5-2min before the intended end of the blowing. The increased component of the weight of the FeO in the slag in said period is then determined by using the analysis values and the quantity of the non-decarburizing oxygen. The component concns. of the Mn and P at the end of the blowing are estimated by calculation. The component concns. of the Mn and P are thereby accurately estimated and the tapping is speeded up.
