Title: Testing method of intergranular corrosion
Inventor: ZAMA MASATO
IPC: G01N17/02
Filed: 1982-01-21
Abstract: PURPOSE:To detect a chromium lacking layer of a nickel alloy containing the chromium, by finding a polization curve by electric potential carrying out active dissolution of nickel in an aqueous solution containing nitric acid and measuring electric current density of its positive polarization curve. CONSTITUTION:A nickel alloy containing chromium e.g. called an ''Inconel 600 '' used for a sample. A positive polarization curve is prepared by electric potential carrying out active dissolution by nickel immersing the smaple in an aqueous solution containing nitric acid. The reason why it is set at this electric potential is that only adjacent crystal grain boundary is corroded selectively and a chromium lacking layer is detected easily by polarizing positively by the electric potential carrying out the active dissolution of the nickel because the nickel concentration in a chromium layer is shown the value near the nickel concentration other than this domain. A detected result is decided by measuring current density in an activity domain of the positive polarization curve. In such a method, intergranular corrosion of the nickel alloy containing the chromium having  low sensitivity is detected sensitively and test time is shortened.

Title: Optical-path branching device
Inventor: WADA ICHIROU
IPC: G02B6/28
Filed: 1980-01-26
Abstract: PURPOSE:To branch light in transmission at a random transfer ratio, by providing the 2nd optical fiber coil around the 1st optical fiber coil with a smaller radius of curvature. CONSTITUTION:Bobbin 10 of a small diameter is wound with optical fiber 11 to form a fiber coil. Since this fiber coil has a small radius of curvature, light in transmission leaks out. To utilize this, optical fibers 12, 13 and 14 are wound around fiber 11 to proper numbers of turns respectively, superposing them on fiber 11. Consequently, light transfer ratios of fiber 11 to fibers 12-14 bear the relation among the numbers of turns of a transformer, so that the numbers of turns of fibers 12-14 can previously be calculated according to the transfer ratios. Thus, the light in transmission can be branched at a random transfer ratio.

Abstract: PURPOSE:To prevent the deterioration of a picture quality due to reducing conversion by setting a run length at '1' when a residual is larger than a limiting value, setting it at '0' when the residual is smaller, when the run length of the conversion picture is set at '1'. CONSTITUTION:The output of a run length converting part 2 and the output of a reduction ratio memory part 10 are multiplication-operated by a multiplier 11. The output of a residual part 12 and that of the multiplier 11 are sent to an adder 13, and the output is sent to a decision processing part 16 and also to a comparator 15. The decision processing of the decision processing part 16 is as follows. When the output of the adder 13 is larger than '1' an integer part is made into the run length of the conversion picture, and a decimal part is made into the residual. When the output is smaller than '1' and the residual does not exceed the limiting value, the run length is set at '1' and when the residual exceeds the limiting value, the run length is set at '0'. Thus, a black fine line in a large white ground can be prevented from being erased.
