Abstract: PROBLEM TO BE SOLVED: To detect the position of a reinforcing bar buried in an ALC panel by detecting the amplitude variation of electrical oscillations from an eddy- current displacement sensor by bringing the sensor nearer to the header face of the panel while the panel is carried on its production line. SOLUTION: A panel position detector 5 detects an ALC panel when the panel 1 arrives at a prescribed position while the panel 1 is carried on a transporting device 8. Then a sensor moving device 9 brings an eddy-current displacement sensor 7 nearer to the header face 4 of the panel 1 based on the detect signal of the detector 5 and the sensor 7 detects the covering depth of a reinforcing bar (auxiliary bar) 2 from the header surface of the panel 1. When the covering depth is detected, a device for detecting position of buried reinforcing bar in ALC panel outputs some signal in accordance with the detected covering depth, whether or not the depth is smaller than a prescribed value, for informing the defectless/defective condition of the panel 1.  When it is detected that the covering depth of the bar 2 is a specified value, the sensor returns to the original position by leaving the header face 4 of the panel 1 behind and waits for the next panel to be carried in.

Filed: 1992-12-25
Abstract: PURPOSE:To obtain a high sensitive detecting element by providing an element section of a magnetic film with high permeability insulated by an insulating layer in a hollow section of a film hollow ring with high conductivity. CONSTITUTION:A hollow ring 3 is made of a metallic film with high conductivity such as Cu, Au or the like or an ultra conductivity film such as Nb, Nb3Sn, Y or the like and a magnetic film 2 with high permeability is made of Co-Zr or Fe-Ni. The boundary section therebetween is insulated by an insulating layer. When a distribution of magnetization is detected, an electron wave with coherency is applied on the ring to flow 3 from point A to point B. The electron wave passes through two passages of A, C, B root and A, D, B root. When the wave reaches point B, the differential phase phid becomes a value of phid=2pie.PHI/h (e: electron charge quantity, h: Planck's constant, PHI: magnetic flux). When phi is varied, an interference fringe of the electron wave becomes a value of phid=2pie.PHI/h on the condition wherein a magnetic flux quantum phi0 is phi0=h/e to periodically change in a period of the magnetic quantum. As a result, the change of intensity of the electron wave due to the interference fringe can be detected so that the magnitude of the magnetization can be observed.
