Title: High strength steel excellent in hydrogen embrittlement resistance and its production
Inventor: NAMIMURA YUUICHI
IPC: C22C38/04
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To improve hydrogen embrittlement resistance by specifying critical diffusible hydrogen content. SOLUTION: Although the delayed fracture of a steel material is greatly affected by the hydrogen (diffusible hydrogen) moving around in the steel material, hydrogen embrittlement becomes remarkably changed according to the composition of the steel material even if diffusible hydrogen content is unchanged. Therefore, by using the prescribed measuring method of critical diffusible hydrogen content, the critical diffusible hydrogen content causing no delayed fracture, taking the sensitivity to the diffusible hydrogen into account, can be accurately grasped. By this method, it is ascertained that, independently of the composition, etc., of the steel material, the steel material having 0.15ppm critical diffusible hydrogen content produces excellent hydrogen embrittlement resistance with certainty.

Filed: 1983-07-22
Abstract: PURPOSE:To eliminate the use of an overflow detecting circuit and to simplify the timing control for division by performing a division operation through the normalization of a divided and the addition of two compliment values of a dividend and a divisor. CONSTITUTION:A dividend and a complement of 2 of a divisor are fed to a dividend register 31 and a divisor register 32 respectively to be normalized there. Then a quotient register 33 is cleared and the loop frequency is set to a loop counter 36. The value of the register 32 is shifted by arithmetic to the right to be 1/2-multiplied. The value of the register 31 is added to that of the register 32 and supplied to the register 31. Then 1 is added to the value of the register 33. Both registers 31 and 33 are simultaneously shifted left until the value of the register 31 is normalized. In this case, the setting frequency of the counter 36 is reduced for each shift of both registers. Then said addition and normalization are carried out until the above-mentioned setting frequency is set at 0. As a result, both of a quotient and the residual are set to registers 33 and 31 respectively.

IPC: G02B21/00
Filed: 1992-05-27
Abstract: PURPOSE:To stably detect the three-dimensional form of objects having various reflecting conditions at high speed. CONSTITUTION:An illuminating polarized laser beam 2 is linearly throttled onto an illuminating slit 16 by a lens 8 and a cylindrical lens 15. 17 is a field lens for regulating the direction of luminous flux. The light emitted from the illuminating slit 16 is passed through an opaque mirror 14 and linearly imaged on the object by an objective lens 5. The reflected light from the object is imaged on a linear sensor 4 by the objective lens 5. In the front of the linear sensor 4, a polarizing plate 11 is placed to pass only the scattered light. The linear sensor 4 is formed of small light detectors of 10-20mum arranged in a line, which has the effect as a slit by itself, and the linear illumination on the object and the linear sensor form a co-focusing system. The detecting sensitivity is enhanced by use of an accumulating type linear sensor, and since the linear sensor is used, mechanical scanning can be reduced to two axes, which has a great effect on the simplification of the detecting system.
