摘要： PROBLEM TO BE SOLVED: To obtain a hydraulic composition aiming at the improvement of a flowing property, a compression strength and a bending strength by containing a hydraulic inorganic material and a specific hydraulic organic material. SOLUTION: This hydraulic composition is obtained by blending 3-30wt.% of an organic hydraulic material with an inorganic hydraulic material such as a cement, a gypsum, an apatite, etc. The hydraulic material is obtained by blending a reaction product obtained by reaction 1mol of a compound having amino group and/or imino group and sulfone group with 0.2-3mol of a polyamine at 50-90 deg.C for 2-5hr, with 0.2-2mol of a compound having glycidyl group based on 1mol polyamine.

摘要： PROBLEM TO BE SOLVED: To improve the yield of a disilane and enable the control of the production ratio of monosilane and disilane by preparing a silicon-magnesium alloy using silicon subjected to a specific preparatory heat-treatment and using the obtained alloy as a raw material for the production of a silane compound. SOLUTION: An alloy of magnesium and silicon subjected to preparatory heat-treatment at >=800 deg.C and below the melting point for >=10min is baked. The obtained alloy is kneaded and reacted with an ammonium halide in liquid ammonia solvent to obtain a silane compound. The production ratio of monosilane to disilane can be controlled by controlling the baking temperature and the heating period of the silicon used as a raw material for the alloy. The heat-treatment of silicon is preferably carried out in an inert gas atmosphere such as argon or helium.

摘要： PROBLEM TO BE SOLVED: To efficiently produce a gypsum board, in a gypsum board producing method having a continuous feed process using a belt conveyor, by continuously measuring the edge angle of a molded object by a roller type contact device to adjust the same. SOLUTION: When a detection roller 7 comes into contact with the edge surface of a board molded object during feed, the roller 7 is not rotated and, therefore, it is operated so as to come into contact with the edge surface of the board molded object by the horizontal component of the wt. of an edge angle measuring device main body 5. Since the roller 7 of an edge angle measuring device is brought into contact with the edge surface of the board molded object to be allowed to follow the same when the edge angle of the board molded object is improper, the angle measuring device main body 5 is preliminarily unbalanced by a proper angle. A clinometer 8 is attached to the measuring device main body 5 and, when the roller 7 is vertical, an electric signal corresponding to 90 deg. is outputted. By this constitution, the edge angle of the board molded object can be continuously measured during feed to be adjusted.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily form an optical waveguide for surface mounting having a total reflection surface by irradiating a resist with active energy rays in such a manner that the irradiation quantity of the active energy rays of the part corresponding to the specific total reflection end face part of the optical waveguide is continuously decreased or increased. SOLUTION: At the time of forming the optical waveguide by irradiating the resist with the active energy rays and developing the resist in the processing for manufacturing the optical waveguide having the total reflection end face of 45 deg. for a surface packaged optical circuit, the resist is irradiated so that the irradiation quantity of the active energy rays of the part corresponding to the total reflection end face of 45 deg. of the optical waveguide is continuously decreased or increased. The photoresist to be used is preferably a resin which does not absorb light for optical communication, such as acrylic resin. As a method of continuously changing the irradiation quantity of the active energy rays, the resist is irradiated with the active energy rays through a photomask formed to continuously change the transmission quantity of the active energy rays or the output of the active energy rays is continuously changed under scanning with the active energy rays.

摘要： PROBLEM TO BE SOLVED: To obtain a trialkyl aluminum useful as a catalyst for polymerizing olefins at a high reaction rate in a high yield. SOLUTION: This method for producing the trialkyl aluminum comprises reacting an amorphous type aluminum-magnesium alloy uniform in the composition with an alkyl halide, if necessary, in the presence of methylaluminum sesquichloride, etc., as a reaction initiator in a solvent (e.g. n-hexane). The aluminum-magnesium alloy has an aluminum content of 35-45wt.% and a magnesium content of 55-65wt.%, and is obtained by melting aluminum and magnesium, and subsequently quickly cooling and solidifying the melted mixture at a rate of >=10 K/sec. The employment of the aluminum-magnesium alloy enables to accelerate the reaction and obtain the objective compound in a high yield within 15 hr or shorter, while conventional methods require a reaction time of approximately 24hr.
