Title: Safety device for feeding movable bed
Inventor: UNNO KUNIHIKO
IPC: B24B47/20
Filed: 1981-06-18
Abstract: PURPOSE:To provide the positive brake action of a safety cylinder to improve safety even if a servo motor is accidentally operated, by always filling with liquid the safety cylinder for restraining feed speed of a grinding wheel bed. CONSTITUTION:When feed speed of a grinding wheel bed 2 is changed higher than quick feed speed by any failure, hydraulic pressure in a cylinder chamber 17b is raised higher than a set value by the relative movement between a cylinder 17 and a piston 18 after an abutting member 26 abuts against a reference member 25, and correspondingly a pressure responsive closing valve 21 is oprated to close a throttle path. Thus oil flow from the cylinder chamber 17b to a cylinder chamber 17a is shut off to stop forcibly the movement of a grinding wheel bed 2.

Title: Production of high toughness steel
Inventor: TAKEZAWA HIROSHI
IPC: C21D8/02
Filed: 1993-04-21
Abstract: PURPOSE:To efficiently produce a steel plate for structural use, excellent in toughness and having fine-grained structure in a surface layer part. CONSTITUTION:A slab prepared by combining steels, where the Ar3 transformation point of chemical components of a steel constituting the surface and the rear surface part comprising, in total, <=50% in a thickness direction is higher by >=30 deg.C than the Ar3 transformation point of chemical components of a steel constituting the central part of plate thickness, is used. This steel plate, having high toughness in surface layer part, can be produced essentially by applying, at the time of hot rolling, rolling where, in succession to rolling for surface layer part at >=40% at a temp. between the Ar3 transformation point and (Ar3 transformation point + 150 deg.C), rolling of, in total, >=30% is done by means of heavy draft of >=10% rolling reduction per pass at a temp. not higher than the Ar3 transformation point. Forced cooling at the time of rolling is applied to the above, and further, if necessary, successive tempering treatment is done. By this method, a fine-grained structure can be formed in the surface layer part without forced cooling in the course of rolling, and the steel plate excellent in toughness can be produced.

Abstract: PURPOSE: To obtain the dispersant capable of lowering the viscosity of a coal powder aqeuous slurry and of raising its transportability by using as an effective component the sulfonate or its salt of a polycyclic aromatic compound or a formalin condensate of these.  
     CONSTITUTION: The dispersant contains as an effective component one or more of a sulfonate (e.g., naphthalene) of its salt (e.g., Na-salt) of the polycyclic aromatic compound, having often a hydrocarbon substituent, or a formalin condensate of these. The preferred condensation degree of the said formalin condensate used is 1.2W30, more preferably 1.2W10. In general, the dispersant is added to a 30W 85wt% coal powder aqueous slurry of preferably 50W75wt% slurry in a proportion of 0.001W5.0wt%, especially 0.05W2.0wt%. Thus, the transportability and ash separability of the coal powder aqueous slurry can be raised, and in addition, its dehydrating property can be raised because the deposited volume of the coal powder when sedimented is small.
