Abstract: PURPOSE: To effectively prevent the corrosion of a metal basically composed of iron in contact with an aq. system by adding a specific aminohydroxy succinic acid compd. or its water-soluble salt to the aq. system at a specific concn.  
     CONSTITUTION: This org. corrosion inhibitor has the compsn. consisting of the aminohydroxy succinic acid compd. which is the compd. expressed by the general formula (R is H, OH, CO 2 H, SO 3 H, alkyl, cycloalkyl, phenyl, R' is H, alkyl, Z is C(CH 2 ) n , etc.) or its water-soluble salt. The agent is effective for preventing the corrosion of the ferrous metal in contact with the water-soluble system. The corrosion preventive agent is used by adding the agent in the amt. of 0.1 to 500 ppm, more preferably 0.1 to 100 ppm to the aq. system. At this time, the aq. system is preferably maintained at pH of about ≥7, more particularly preferably about ≥8.

Title: Optical fiber
Inventor: KAJIOKA HIROSHI
IPC: G02B6/036
Filed: 1987-11-24
Abstract: PURPOSE:To increase the strength of an optical fiber at a low cost by providing a high-purity synthetic glass layer on the surface of the support of the optical fiber. CONSTITUTION:The surface of the support 3 consisting of low-purity glass is coated with the high-purity glass layer 4 to prevent microcracking. Namely, the part where light is transmitted is just about 1% (by weight) of the entire part of the fiber in the case of the optical fiber, more particularly, single mode optical fiber and, therefore, the support layer is constituted of the low-grade glass. The higher strength is thereby obtd. at the low loss and low cost.
