Abstract: PURPOSE:To produce inexpensively an electric welded steel pipe for automobiles which has high quenched hardness, by subjecting the electric welded steel pipe formed of a steel contg. C, Si, Mn, etc. having a specific compsn. and compsn. relation to specific normalizing and hardening. CONSTITUTION:A hot-rolled steel sheet obtd. from the steel consisting of 0.30- 0.35% C, 0.10-0.30% Si, 1.40-2.00% Mn and the balance Fe and unavoidable elements and contg. <=4.0 or 5.5-7.0 Mn/C is formed to a tubular body, and the edges of the tubular body are welded by heating, thereby forming a steel pipe. The resultant electric welded steel pipe is normalized at 800-950 deg.X for 1-5min by a bright normalizing furnace or the like to relieve strain and to make the texture uniform and fine in grains. The steel pipe is allowed to cool after the normalizing. Such steel pipe is further quickly heated to 950-1,050 deg.C at >=50 deg.C/ min heating rate between Ac1-Ac3 by a high frequency heating coil or the like, and is immediately hardened at >=250 deg.C/sec cooling rate without holding, whereby the electric welded steel pipe having >=600Hv quenched hardness for automobiles is obtd.

Title: Nmr image sensor
Inventor: SHIMAZAKI TORU
IPC: G01R33/48
Filed: 1985-06-20
Abstract: PURPOSE:To enable intuitional estimation of the effect of relaxation time on an image, by arranging an NMR to obtain an image with a logarithmic conversion at each pixel while a plurality of images corresponding to the relaxation time by scanning. CONSTITUTION:An NMR mechanism 10 is operated to obtain an echo signal at each view. Then, the signal is passed through an RF phase detector 11 and digitalized with an A/D converter 12 to be stored into a data memory 13. An echo signal is obtained over the entire view by the same time sequence to reconstruct an image with an arithmetic unit 14. The image is stored temporarily into a buffer memory 15. About the image, an image data is converted with an arithmetic unit 14 logarithmically at each pixel and stored into an image memory 16 to be displayed 17 properly. This enables the reflection of the effect of the relaxation time T1 and T2 attenuated expotentially on a linear scale with time on the image, thereby achieving an image contrast by the T1 and T2 accentuation with an intuitional determination of the relaxation times in the interest area.
