Abstract: PURPOSE:To develop a porous sintered material for safe hydrogen occlusion which is simply handleable, not deteriorating hydrogen occlusion ability, by blending fine powder of hydrogen occlusion alloy with fine powder of ceramic, followed by sintering the blend. CONSTITUTION:50-80wt% fine powder of hydrogen occlusion alloy having 1- 10mum particle diameters, having occluded hydrogen and being inert, is blended with the rest of one or more ceramics such as aumina, zirconia, titania, silica, etc., consisting of fine particles having 10-100mum particle diameters, to give mixed particles, which are sintered in high temperature and high-presshre hydrogen atmosphere. Since the ceramic is used as a substrate for the hydrogen occlusion alloy, a porous sintered material is obtained, and a hydrogen occlusion material not causing pulverization of the hydrogen occlusion alloy nor reduction of hydrogen occlusion ability, is obtained.

Abstract: A genomic library of Erwinia chrsyanthemi DNA was constructed in bacteriophage  lambda  1059 and recombinants expressing E.chrysanthemi asparaginase detected using purified anti-asparaginase IgG. The gene was subcloned on a 4.7-kb Eco R1 DNA restriction fragment into pUC9 to generate the recombinant plasmid pASN30. A restriction map of pASN30 was constructed and the position and orientation of the asparaginase structural gene determined by subcloning. The enzyme was produced at high levels in Erwinia carotovera and in Escherichia coli (>5% of soluble protein) and was shown to be exported to the periplasmic space.

Title: Document preparing device
Inventor: SUZUKI FUMIHIRO
IPC: G06F17/22
Filed: 1990-07-13
Abstract: PURPOSE:To facilitate repetitive input operation by regarding characters corresponding to stored character codes as candidates for next input characters and using a character selected among the candidate characters for the generation of text data. CONSTITUTION:Characters which are inputted by a by-radical input system are stored in a special input character memory 8 and when the re-input of a special input character is indicated, the characters stored in this special input character memory 8 are used as candidate characters to be inputted. Then the character selected among the candidate characters is decided as an input character. Therefore, when an operator re-inputs a character which is inputted once by the by-radical input system, the re-input of the special input character is indicated (for example, by pressing a corresponding key) and one of the candidate characters is selected, thus inputting the character by the easy operation. Consequently, the frequency of character input operation by the by-radical input system which is more complicated than usual can be decreased and the document preparing speed is improved.

IPC: B22C1/04
Filed: 1980-12-24
Abstract: PURPOSE: To obtain a furan mold which causes no cementation despite the repeated casting of cast steel by kneading and molding molding sand and ignition additives of enzyme type, saccharides type and alcohol type together with a furan resin binder and a hardener.  
     CONSTITUTION: A furan mold is crushed to sand grains, after which a furan resin binder, a hardener (e.g.; toluene sulfonic acid), and ignition additives of enzyme type, saccharides type and alcohol type are added to this molding sand having a large content of residual carbon respectively at prescribed ratios, and the mixture is kneaded and molded, whereby a furan mold is made. Thence, cast steel, stainless cast steel, etc. are cast by using this furan mold. As a result of this casting, the decomposed gases of the carbon, furan resin binder, etc. stuck to the molding sand are burned by the air in the molding sand. At this time, carbons are mostly turned to CO 2  by the catalytic effect of the ignition additives, whereby the CO which is the factor for cementation is decreased considerably, and the cementation to cast steel is prevented over a long period of time.

Title: Molten metal pouring nozzle
Inventor: YAMAGAMI JUN
IPC: B22D41/50
Filed: 1986-08-06
Abstract: PURPOSE:To eliminate the drift of a molten metal in a nozzle and to prevent the intrusion of impurities into the molten metal by stirring of the molten metal surface by decreasing the inside diameter of the region of the inside wall of the nozzle where the molten metal collides, thereby forming a step part. CONSTITUTION:The molten metal 22 in a tundish 21 is poured through an outflow port 23 and a nozzle 31 into a casting mold 34. The molten steel flow is drifted when the aperture area of a flow port 30 is adjusted by moving a sliding plate 28 in the direction of an arrow 29. The inside diameter of the region 41 where the drift collides is, therefore, decreased to provide the step part. The flow velocity of the molten steel flow is lowered by the step part 41 and the molten steel flow is directed downward, by which the drift is eliminated. The molten steel is thereby uniformly discharged from an outflow hole 32 and the intrusion of powder 36 to prevent the oxidation of the molten steel in the casting mold 34 is prevented.
