Title: Removal of casting core
Inventor: IMAMURA TETSUO
IPC: B22D31/00
Filed: 1984-02-17
Abstract: PURPOSE:To remove safely and surely core sand by exerting the pressure to the extent of generating strain in the outside casting metal part of a casting having internally a core to generate cracks in the core thereby collapsing the core. CONSTITUTION:Load is impressed in an arrow 4 direction to a casting metal 1 having a core 2 within the elastic region of the external casting metal part of the metal 1 to apply deformation to the metal 1. The load is within the elastic region and therefore if the load is removed, the metal 1 restores the original shape and a difference arises in the strain and stress generated in the metal 1 and the core 2 as said metal and core have different Young's moduli. When such operation is made repeatedly, only the core 2 is fatigued and broken as the core 2 has the larger Young's modulus while the metal 1 has the smaller Young's modulus. The core 2 existing in the casting metal is thus easily collapsed and removed.

Title: Test of magnetic resistance element
Inventor: KUME TOMIO
IPC: G11B5/455
Filed: 1984-02-15
Abstract: PURPOSE:To decide the quality of an MR element before it is manufactured to obtain the effect to reduce the variation of the manufacturing process by forming the dummy element of the MR head in such a way that its current density, element temperature, strain, etc., are set to equal conditions to those set to actual heads. CONSTITUTION:The degree of dependence on electric current of a magnetic field value Hk is measured by putting the thin film of an MT element on a crystal substrate, on which a dummy element is put, so that the lengthwise and breadthwise dimensions of the thin film become proportional to those of an actual MR element and measuring its characteristic curve by making various electric currents Is to flow to the dummy element formed through the same manufacturing process as that applied to an actual MR head. In the case of a dummy element whose quantity of magnetostriction lambda is negative, the magnetic field value Hk rises as the electric current Is increases. On the other hand, in the case of an MR element whose quantity of magnetostriction lambda is positive, the magnetic field value Hk does not change even when the electric current Is increases. By forming the dummy element of the MR head in such a way that its current density, element temperature, strain, etc., are set to equal conditions to those set to an actual head, variation of the manufacturing process of the MR element can be reduced.
