IPC: B22D11/16
Filed: 1991-02-08
Abstract: PURPOSE:To obtain the measuring value shifting continuously and smooth by avoiding the separated gap of the measured value at the detector changing time caused on the variance of the detecting characteristic of each detector on the case that the broad measuring range is divided and measured with plural detectors. CONSTITUTION:Plural pieces of the level detectors are set to the level changing direction (vertical direction) by repetitionally setting the end ranges (v1-v2), (v3-v4) of the detecting range (v1-v4) of the detectors adjoined each other, the level detected value La of the detector (4a-10a) that the detected voltage (SVa) is within the set range (v1-v4) is extracted, if it is in the end range (v1-v2), the level detected values Lb and La of the adjoined detectors are executed with weighted averaging by giving the high rate of contribution alpha=(Sva-v1)/(v2-v1), 1-alpha to the detected values of the detector which is near the molten metal level, and the level detected value L=alpha.La+(1-alpha) Lb is obtained.

Filed: 1990-01-30
Abstract: PURPOSE: To give no damage to a part contacting with a flange and around it by providing a spacer to be deformed by compression force on a fastener in the case when a tubular body of the fastener is pushed forward toward a bolt head part and is fixed on and engaged with a bolt each other. CONSTITUTION: When a fastener is installed on a work piece of thickness smaller than the expected maximum thickness, a tubular body 4 makes contact with a spacer 10 before a flange 5 of the tubular body 4 is engaged with a surface of a panel (b), and the spacer 10 is shortened in the axial direction. Force to be required to deform the spacer 10 increases size of force required to bring the tubular body 4 close to a bolt head part 2 to size near to force required to cut a bolt 1 by a head part 9 for cutting. At the time when the flange 5 is engaged with the panel, still smaller force is required to compress the spring (b), and accordingly, all the force to be applied speedily increases up to size which the head part 9 cannot maintain, the head part 9 is broken, and compression force is prevented from working further on the work piece.

IPC: G21C3/62
Filed: 1989-01-27
Abstract: PURPOSE:To produce a molybdenum tray for high-temp. sintering in which the occurrence of adhesion is prevented by successively forming an undercoat layer of molybdenum and a surface layer of ceramics on the surface of a molybdenum base material by a plasma spraying method and then burning the resulting coating layer at high temp. CONSTITUTION:A tray is formed by using a base material of molybdenum or molybdenum-base alloy. As this molybdenum-base alloy, e.g. the one prepared by adding SiO2, K2O, Al2O3, etc., to molybdenum is used. Further, this base material is prepared by the ordinary powder metallurgical method. Subsequently, an undercoat layer enriched in molybdenum and, on the above, a surface layer enriched in heat resisting ceramics are successively formed on the surface of the above base material by means of plasma spraying. The resulting coating layer is burnt at a temp. as high as >=1500 deg.C to improve adhesive strength. The tray obtained by this method causes neither adhesion between mutual trays nor adhesion to other members even if used in a piled state for sintering nuclear reactor fuel, etc., at about 1700-1750 deg.C.
