Title: Temperature measuring instrument
Inventor: TAKAHASHI ATSUSHI
IPC: G01J5/10
Filed: 1991-11-11
Abstract: PURPOSE:To automatically detect the fault of a temperature measuring instrument caused by the deterioration of the thermocouple of a thermocouple thermometer or a decline in measured value of a radiation thermometer. CONSTITUTION:Since an equalizing process is performed on a thermocouple thermometer 2 at a compensation circuit 3, the measured values of two thermometers coincide with each other at a prescribed switching point when the thermocouple of the thermometer 2 is not deteriorated. Therefore, a switching control section 5 switches thermometers to be used by operating a switch 4. Upon switching the thermometers, a comparator 6 compares whether or not switched temperature data are within a preset allowable value range and, when the switched temperature data exceeds the allowable value range, causes a display 7 to display the occurrence of a fault.

Title: Steel wire for spring and its production
Inventor: MATSUMOTO TAKESHI
IPC: B21C1/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To improve strength and rigidity of a steel wire by efficiently causing martensitic transformation in drawing. SOLUTION: In drawing to cause strain induced martensitic transformation, by impressing a magnetic field of >=0.5 tesla, martensitic transformation is efficiently produced to increase a martensitic phase quantity. Further, by limiting a direction of the magnetic field, a crystal orientation of martensitic phase is controlled. That is, a (100) orientation of the martensitic phase of >=50% is made to <=30 deg. for the axial direction. In this case, a ridigity at (100) orientation in the martensitic phase is higher than that of other crystal orientation, in the case the orientation is in a range of <=30 deg. for the axial direction, the (100) orientation is essentially in parallel to the axial line, the rigidity of a steel wire for spring is improved.
