Title: Hot rolling method for martensitic stainless steel
Inventor: OGAWA YUTAKA
IPC: B21B3/02
Filed: 1987-01-26
Abstract: PURPOSE:To omit a slow cooling stage and to prevent generation of cracks at the time of hot charge rolling by charging an ingot into a heating furnace when the ingot is at the martensite transformation point or above and maintaining the heating temp. at <=1200 deg.C. CONSTITUTION:The ingot is heated in the state of the martensite transformation point temp. or above without cooling the sane down to a room temp. in the cooling stage in succession to solidification from the melt of a stainless steel at the time of hot charge rolling of the martensitic stainless steel. The heating temp. prior to hot rolling is maintained at <=1200 deg.C and the hot charge rolling is executed. Since the generation of cracks is promoted with an increase in the heating temp. to 1250 deg.C and 1300 deg.C, the heating temp. is kept at <=1200 deg.C. The slow cooling stage is, therefore, omitted and the generation of cracks in the hot charge rolling is effectively prevented.

Abstract: PURPOSE:To detect the charges of a surface protective film by reverse-biasing a p-n  junction, measuring the extension of a depletion layer in the vicinity of the surface of  a substrate by using optical response and collating the relationship of a bias and the  quantity of extension with known relationship. CONSTITUTION:When reverse bias voltage VA is selected in the avalanche breakdown  voltage or less of the p-n junction, the extension of the depletion layer 12 in the vicinity of the surface is determined by VA and the quantity of charges in the surface protective film.

The change of the photocurrents Ip is obtained as that of a position, and  the width L of the depletion layer can be acquired. When VA is altered and the change  of the width L is plotted, the quantity of charges Q in the surface protective film  prepared previously is used as a parameter and characteristics agreeing with measurement best are selected, the quantity of charges is decided. Calculation value prepared  previously can be obtained by solving a Poisson formula from the size of the element,  the depth of a p layer and the quantity of diffusion, the concentration of a m layer,  the quantity of charges Q in the surface protective film and bias voltage VA. In the  constitution, special structure is unnecessitated completely.
