Patent JP-H03266219-A (JP)
Title: Production of magnetic recording medium
Inventor: HIRANO HIROSHI
IPC: G11B5/84
Filed: 1990-03-15
Abstract: PURPOSE:To reduce the cupping degree of a medium and to improve the head contact state by winding the medium with a back coating surface outside after the back coating layer is formed and then subjecting the medium to heat treat ment. CONSTITUTION:The magnetic recording medium has a metal magnetic thin film 2 formed on the one side of a nonmagnetic supporting body 3 and has a back coating layer 1 formed on the other side. This medium is wound with the back coating side 1 outside and then subjected to heat treatment. Namely, by subjecting the medium in a wound state to heat treatment, the medium experiences tensile force as a whole due to the influence of the nonmagnetic supporting body since the supporting body has larger thermal shrinkage than the magnetic layer and then the back coating layer. The force appearing in the outer surface of the wound supporting body is larger than the force in the inner surface because of small difference of circumferences. When the medium is subjected to heat treatment with the back coating layer outside, the tensile force and shrinking stress compensate for each other at a certain degree to give almost equal force on the outer surface and inner surface. Thus, cupping of the medium is reduced and good head contact is obtained.

Title: Arithmetic processing unit
Inventor: YAMADA IKUO
IPC: G06F7/485
Filed: 1985-03-29
Abstract: PURPOSE:To facilitate detection of overflow and underflow in which the sign of an index is lost and the control of later restoration and to simplify the constitution of the titled unit by changing an index of floating point data from the expression increased by 64 to the expression of complement of 2, making sign expansion and applying index conversion. CONSTITUTION:Floating point data of expression increased by 64 are inputted to the index adder of an arithmetic processing unit, and the index data are calculated by the expression of complement of 2. Index correction of post normalization is processed by an index correction adder 10 between output of the adder 5 and the quantity of post normalization. Floating point data are inputted by the sign expanding circuit 1 of the device, and the highest bit of the index part is inverted. The inverted bit is sign expanded to higher rank and outputted to the adder 5. Underflow and overflow of index are detected by an exception detecting circuit 12 and an exception flag register 13 from final result of index operation from the adder 10. The final result of index operation is inverted by a sign inverting circuit 18 and outputted, and hardware and software of the device are simplified.

Filed: 1988-03-17
Abstract: PURPOSE: To measure a parameter, such as the temperature, etc., by changing the plane of polarization of a luminous flux by applying a modulating voltage across a birefringent material or impressing a magnetic field upon the material. CONSTITUTION: Polychromatic light polarized by means of a polarizer 7 is split into a normal luminous flux and an abnormal luminous flux when the light passes through a birefringent material, 6 and the luminous fluxes interfere with each other at a certain wavelength. Therefore, the light transmitted through a fiber 2 becomes polychromatic light lacking in a certain wavelength component and the light reaching a detector 4 develops a characteristic color. The change of a parameter to be measured, such as the temperature or magnetic field is adjusted so that the light reaching the detector 4 can develop various colors by changing the length of the optical path of the polychromatic light passing through the material 6. A microprocessor 13 analyzes the color of the detected light by calculating signals from photosensitive elements 9 and 10.
