Title: Stainless alloy having few flaw formed by rolling in hot rolling
Inventor: UEDA MASANORI
IPC: C22C38/00
Filed: 1980-07-03
Abstract: PURPOSE: To reduce the formation of flaws due to rolling in hot rolling, by carrying out the adjustment of alloy components based on S, P and O in a stainless alloy.  
     CONSTITUTION: The stainless alloy comprising 0.001W0.20wt% C, 0.1W6.0wt% Si, 0.1W10.0wt% Mn, 0.06wt% or less P, 0.01wt% or less S, 15.0W35.0% Cr, 3.5W35.0wt% Ni, 0.001W0.50wt% N, 0.01wt% or less O, at least one element of 6.0% or less Mo, 4.0wt% or less Cu, 1.0wt% or less Nb and 0.1wt% or less Sn, and the remainder of substantially Fe, having a value of δ cal  of formula I or 4.0% or less and meeting he condition of formula II. Since S is a main cause for the formation of pills, the minimum content of it is preferable and when the content exceeds its upper limit, the hot workability of the alloy is deteriorated even with other means tried. O and P also promote the formation of pills so that the minimum content of them is preferable. Other components have influence on the formation of pills through the δ cal . The more negative the δ cal  the more easily the pills are formed. When the δ cal  is positive, the distribution of S, P and O is made uniform, a good effect being obtained, but when the δ cal  exceeds 4, the uniform distribution of them is reversely deteriorated.

Filed: 1989-04-10
Abstract: PURPOSE:To arbitrarily select a wave front shape of an output destination by coupling an optical waveguide having no gain against oscillation wavelength to an array-like optical waveguide having the gain, and controlling the respective injecting currents. CONSTITUTION:A semiconductor laser array 3 is constituted by coupling optically window area optical waveguides 4-1b to 4-nb having no gain to gain waveguide type optical waveguides 4-1a to 4-na having the gain against oscillation wavelength. To the optical waveguides 4-1b to 4-nb, a current is injected through phase control use electrodes 6-1 to 6-n in accordance with setting of a wave front controller 8. In this case, when the injecting current quantity is controlled, effective resonator length is varied, therefore, a phase on the output surface is varied. In such a way, an arbitrary wave front shape can be constituted without varying the wavelength of an input destination and without using a plane wave.

Then, an SiO2 glass particulate layer 2a is formed thereupon. The substrate is heated to diffuse the thin film 5 into the layer 2a and make the layer 2a transparent, forming a core layer 2b. Then, a desired circuit pattern is formed by reactive sputter etching. In this case, the width of the light guide is set larger than that of a dopant diffusion part 5b. Porous quartz glass is deposited thereupon and made transparent to form a clad layer 3. Consequently, the quartz system light quide which has good consistency with fibers and is under a little influence of the roughening of the light guide surface, deformation of the circuit shape, etc., is obtained.
