Title: Method for continuously casting titanium-adding extra-low carbon steel
Inventor: SEZE AKIFUMI
IPC: B22D11/11
Filed: 1995-02-28
Abstract: PURPOSE: To industrially and stably produce a titanium-adding extra-low carbon steel having little surface flaw at a low cost by cast ing while electromagnetically stirring molten steel in a mold. CONSTITUTION: The extra-low carbon steel having <=0.01wt.% carbon content in the steel and adding a titanium in the range of 0.005-0.150wt.% is continuously cast. Molten steel is cast while electromagnetic ally stirring in the mold. In the case of indicating a degree of micro-segregation with a relative degree of the segregation at the time of showing the max. degree of the segregation of the titanium without electromagnetic stirring as 100, the case of continuously casting while executing the electromagnetic stirring in the mold is reduced to about 15% the max. concn. of the micro-segregation on the surface layer of a cast slab in comparison with the case which does not execute this electromagnetic stirring, and the developing ratio on the surface flaw caused by the oxide scale at the time of heating the slab is reduced.  By this method, the yield of the product can drastically be improved.

Title: Oxygen concentrating device
Inventor: MATSUBARA SADAKAZU
IPC: A61M16/10
Filed: 1991-03-06
Abstract: PURPOSE:To prevent drop of the oxygen concentration even with a large rate of flow of an oxygen concentrated gas to be used by precluding an oxygen concentrated gas having flowed in the later period of the adsorption process from mixing with the oxygen concentrated gas, which flowed in before, when such gas is going to flow into a surge tank. CONSTITUTION:An adsorption floor 1 is filled with an adsorbent 10, and a compressor 4 equipped with a relief valve 25 is coupled with the adsorption floor 1 through a two-gang poppet valve 5 while a surge tank 2 is coupled with the floor 1 through an automatic opening/closing valve 12. Inside of the surge tank 2, a number of partitioning plates 16 each having opening 15 are arranged so that the openings are dislocated alternately, and oxygen concentrated gas from a conduit 13 flows into the surge tank 2 bit by bit, wherein it is not likely that the gas having flowed in previously is mixed with the gas flowing in later. Even though an oxygen concentrated gas with some sunk concentration in the final period of the adsorption process flows into the surge tank, therefore, the gas is not likely to mix with the oxygen concentrated gas having a high concentration which flowed in before.

Title: Manufacture of semiconductor device
Inventor: SHIOTANI YOSHIMI
IPC: H01L21/316
Filed: 1981-04-30
Abstract: PURPOSE:To improve the quality of a PSG film by a method wherein a PSG film which contains less oxygen than the stoichiometric composition is formed on a semiconductor substrate and the film is annealed in O2 gas or wet O2 gas at the temperature not higher than the specific temperature. CONSTITUTION:When a PSG film is forms on an Si substrate1 by reduced pressure CVD method and plasma CVD method, a PSG film which contains less oxygen than the stoichiometric composition is formed by, for instance, making O2/(SiH4+PH3) less than 2 when gases such as SiH4, O2 or PH3 are introduced into a reaction tube. Then the PSG film is annealed in O2 gas or wet O2 gas at the temperature not higher than 900 deg.C. With the constitution, the segregation of P at the boundary of the PSG film and the Si substrate generated by the causes such as the diffusion process or the glass flow is avoided even in the thermal treatment in N2 atmosphere. Accordingly, when the PSG film is etched, the secular change of the etching rate is reduced and the abnormal diffusion is also reduced.

Abstract: PURPOSE:A beverage that contains alpha-glucosylisoflavonoid, but being free from its bitterness, astringency and acridness, is thus used advantageously to increase, keep and recover health. CONSTITUTION:An alpha-glucosyl transferase such as originating from an animal e.g., from liver of pigs or from a plant such as buckwheat seeds, from fungi in, e.g., mucor or penicillium or from yeast, e.g., Saccharomyces, is made to act on an aqueous solution containing isoflavonoid originating from soybeans and an alpha-glucosyl saccharide such as partial hydrolyzate of starch or sucrose. Then the resultant alpha-glucosylflavonoid is used to prepare the objective beverage. The resultant beverage is free from bitterness, astringency and acridness caused by the isoflavonoid and readily converted into the original isoflavonoid by the action of alpha-glucosidase in vivo. Therefore, it is used for the increase, maintenance and recovery of health with no anxiety of toxicity and side-effects.

Title: Ultrasonic flaw detection system
Inventor: SATOU MASAAKI
IPC: G01N29/04
Filed: 1978-05-30
Abstract: PURPOSE: To reduce the blind sectors at the leading and trailing ends of the material being examined by disposing probe heads which are constituted by plural probes for making flaw detection of different kinds in a plurality so as to be positioned at nearly an equal spacing in the circumferential direction of the material being examined.  
     CONSTITUTION: Probes Xa, Xb detect the flaws in the axial direction of a steel pipe and probes Ya, Yb detect the flaws in the circumferential direction of the steel pipe. Since the probes Xa, Xb, Ya, Yb make full surface flaw detection, the effective beam width in the axial direction of a steel pipe 1 is 1/2 the advancing pitch l per revolution of the steel pipe 1. A probe head M is constituted by the probes Xa, Xb and a probe head N by the probes Xb, Yb. When the steel pipe 1 is spirally scanned with such constitution, the triangular blind sectors produced at the pipe ends become two triangles of bottom side l/2 height πd/2, thus the blind of the pipe ends may be reduced without increasing the number of flaw detection heads.
