Title: Alumina/yttria refractory
Inventor: TAKEMURA FUMIO
IPC: C04B35/101
Filed: 1989-12-26
Abstract: PURPOSE:To obtain a refractory having excellent fire-resistance, corrosion resistance and spalling resistance under severe condition by laminating and integrating an alumina layer and a yttria layer to form a double-layer structure. CONSTITUTION:The objective refractory has a double-layer structure composed of an alumina (Al2O3) layer and a yttria (Y2O3) layer laminated and integrated with each other. The refractory can be produced by calcining alumina powder and yttria powder having controlled particle diameters in air, kneading a binder component to each powdery material, successively filling the alumina component and then the yttria component into a mold in layers and sintering the produced formed material at >=1500 deg.C. Alumina has a melting point of 2050 deg.C and a heat-expansion coefficient of 9.1X10<-4>/ deg.C (at 1000 deg.C). The melting point of yttria is as high as 2410 deg.C but the heat-expansion coefficient of yttria is 9.3X10<-4>/ deg.C (at 1000 deg.C) which is close to that of alumina. Accordingly, the lamination and sintering of the components can be easily carried out to form an integrated texture resistant to interfacial delamination, breakage, etc., even after repeated thermal history.

Filed: 1991-12-25
Abstract: PURPOSE:To identify the kind or quantity of an article by a small sized device without using a detection coil by a method wherein the impedance of an exciting circuit is set so as to be smaller than that of a magnetic fine wire and the change of magnetic flux is detected on the basis of the change of the current waveform of an exciting coil. CONSTITUTION:A detection resistor 9 is connected across an exciting coil 5 and an AC power supply 6 and both ends thereof are connected to a measuring device 8 and the internal impedance of the power supply 6, the value of the resistor 9 and the impedance of the coil 5 are set so as to be smaller than the impedance of a magnetic fine wire so that an exciting current changes in the circuit through which the exciting current flows by the presence of a magnetic marker 1. By this constitution, since the exciting current changes by the change of magnetic flux due to the coercive force of the magnetic fine wire, a detection signal can be taken out by subtracting the differential waveform of an exciting power supply from the waveform change of the current or the differential waveform of said current. Since no detection coil is used at this time, a device becomes simple and a small-sized device can be constituted corresponding to a use purpose such as the identification of a small article 2.
