Title: Production of ultrafine ceramic particle
Inventor: ANZAI HIROSHI
IPC: C01G25/00
Filed: 1985-12-03
Abstract: PURPOSE:To obtain ultrafine ceramic particles having high sintering and reaction activities, by adding a dispersing agent to an aqueous solution of a salt of Zr, Y, Mg or Al and precipitating the salt as a hydroxide or hydrate by a coprecipitation or hydrolysis method. CONSTITUTION:A dispersing agent, e.g. polyethylene glycol, in an amount of about 0.1-15g based on 1l aqueous solution of at least one salt of zirconium, yttrium, magnesium or aluminum, e.g. ZrOCl2 or MgSO4, thereto. A coprecipitation or hydrolysis method is then applied to precipitate the salt as a hydroxide or hydrate. The resultant precipitate is then dried to afford the aimed ultrafine ceramic particles. Since the dispersing agent is incorporated in primary particles at the same time as the formation thereof as a ceramic powder precursor, flocculation can be remarkably reduced to prevent the formation of secondary particles.

IPC: B28B5/02
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an inorganic plate for use as a building material such as an outside wall which restrains the generation of delamination without sacrificing moldability, patterning performance and productivity. SOLUTION: A slurry 13 for a base is fed on a paper making belt 5. Next, the surface of the base slurry 13 is leveled and the base slurry 13 is sucked and dehydrated for preparation of a base mat 17. A slurry 14 for a skin layer is sprayed over the base mat 17 to prepare a laminated mat 16. Thereafter, the laminated mat 16 is press molded and embossed in the surface thereof at the same time while being sucked and dehydrated vertically. Then, the skin layer slurry 14 and the base mat 17, 17 are mixed together in the vicinity of the interface therebetween, which improves the behavior thereof to thereby enhance the integrity of the two materials. In addition, suction and dehydration, press molding and embossing of the laminated mat 16 can be performed simultaneously in a parallel fashion, and this enhances the moldability, patterning performance and productivity of inorganic plates.

Filed: 1985-12-02
Abstract: PURPOSE:To make the full-scale adjustment of a meter at the atmospheric pressure by holding the output voltage value of a rectifying circuit at the atmospheric pressure in a meter driving circuit and adding an adder in the driving circuit. CONSTITUTION:The output VDC of the rectifying circuit 7 is applied to the negative input terminal of an operational amplifier 8a.

A switch 8g is connected across the variable resistor 8e. Further, the output voltage VF of an operational amplifier 8b is applied to the negative input terminal of the operational amplifier 8a through a resistance 8d. Then, the output voltage of the operational amplifier 8a drives the meter 9 through a resistance 9a. Consequently, a pressure measurement based upon the atmospheric pressure is taken once the meter is adjusted, so very reliable pressure data is obtained.

IPC: G02B6/255
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To fusion splice optical fibers varying in mode field diameters to each other with low loss. SOLUTION: The optical fibers 10 and 20 varying in the mode field diameters are butted against each other as shown in (a) and are heated by an arc discharge beam 43 between discharge electrodes 41 and 42.

Title: Heat insulation structural member
Inventor: MATSUMOTO TAKAHIRO
IPC: B32B5/18
Filed: 1987-10-29
Abstract: PURPOSE:To obtain high insulation with ease by using a gas whose freezing point is higher than the temperature of a cold temperature layer region or the entire region which is brought in contact with a low temperature member of a foaming insulation material. CONSTITUTION:When a liquefied nitrogen vessel 1 is filled with liquefied nitrogen, an insulation material 2 is cooled, a foaming gas within an air foam 8 on a low temperature side, say, carbon dioxide is cooled, then solidified. When it is solidified in this manner, a vaccum state is created within the air form 8. As a result, the foaming gas becomes lean to a considerable extent. The penetration route of heat is mainly composed of a base material 6 whose heating area is small. Therefore, the coefficient of the average thermal conductivity of an insulation material 2 indicates a value almost identical to vacuum insulation. If an attempt is made to insert an insulation material to be used in an area where a foaming gas is solidified, say, metal foil 5, such as SUS foil or Al foil, into an interlayer for bonding, such a phenomena in which a surronding air 4 is diffused, and penetrates the air foam 8 in vaccum state, thereby lowers the degree of vaccum, can be minimized. Therefore, a specified insulation capacity can be maintained for a long time. Furthermore, if an attempt is made to cover an insulation material on a low temperature side perfectly with the metal foil 5, and seal the inside in vaccum, the penetration of air can be prevented to a satisfactory extent, which makes it possible to stabilize the insulation performance.
