Abstract: PROBLEM TO BE SOLVED: To perform effective crushing in a crusher provided with a primary crusher and a secondary crusher each having a hammer by detecting a load of the secondary crusher and controlling the rotation of the primary crusher according to a detection signal thereof to adjust the quantity of a material to be treated fed to the secondary crusher. SOLUTION: Primary and Secondary crushers 8, 14 in a crusher are rotated by motors M1, M2, and the secondary crusher 14 secondarily crushes a material to be treated that has been coarsely crushed by the primary crusher 8. At this time, a load detector for detecting a load of the secondary crusher 14 by detecting a load electric current required for rotating the motor M2 is installed, and the rotation of the primary crusher 8 is controlled according to a signal from the load detector by a rotation controller. For example, when the load of the secondary crusher 14 is increased, by reducing the rotation of the primary crusher 8, the quantity of the material to be treated crushed by the primary crusher 8 is lessened. Therefore, the quantity of the material to be treated fed to the secondary crusher 14 is reduced to prevent the crusher from malfunctioning.

Abstract: PURPOSE:To precisely recognize a form by using two cameras and providing a real image/virtual image judging equipment. CONSTITUTION:A real image/virtual image judging equipment 5 judges that a camera 3 takes not only a real image but also a virtual image when two or more images are obtained by an image reader 4, and judges that a camera 9 takes not only the real image but also the virtual image when two or more images are obtained by an image reader 10. At least one of the image readers 4, 10 takes only the real image, and the image readers 4, 10 never take the virtual image at the same time, because the photographing angle is differed between the cameras 3, 9. The real image/virtual image judging equipment 5 selects and transmits the image data of the one taking only the real image of the image readers 4, 10 to a coordinate computing element 6. The coordinate computing element 6 calculates the three-dimensional coordinate of a measurement target 7 on the basis of the image data having only the real image by the real image/virtual image judging equipment 5.
