Title: Treatment of plating liquid
Inventor: TOMARI YOSHIAKI
IPC: C23C18/31
Filed: 1992-11-09
Abstract: PURPOSE:To minimize the loss quantity of valuable matter and to reduce the cost of a treatment by saving of electric energy by separating and removing the phosphorous acid in a waste chemical plating liquid by diffusion dialysis, then separating and removing the phosphorous acid in a dialyzate by electrodialysis. CONSTITUTION:The reduction efficiency of the Ni ions by hypophosphorous acid decreases and the danger of the self-decomposition of a plating bath increases if the concn. of the phosphorous acid in the chemical nickel plating liquid formulated to impart corrosion resistance and wear resistance to iron products exceeds 350g/l as Na2HPO3.5H2O. The hypophosphorous acid and org. acids to be lost at the time of the dialysis is effectively utilized if executing a metal plating stage to a powder and granular core material before a stage for recovering the phosphorous acid in the aged waste liquid. In addition, the concn. of the phosphorous acid increases and such increase is advantageous for the diffusion dialysis. The valuable matter, such as metal coated powder, is thus produced.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which eliminates the need for buffer regions disposed heretofore on the peripheries of a bonding resin and allows the formation to a narrower picture frame and a process for producing the same. SOLUTION: A wiring layer 3 is formed on a wiring side substrate 1 and a color filter 4 is formed on a color filter side substrate 2. The wiring side substrate 1 and the color filter side substrate 2 are bonded via the bonding resin 5 while holding a spacing to be injected with liquid crystals therebetween. The liquid crystals 6 are thereafter injected into the spacing, by which the liquid crystal display device is completed. Grooves 7 are formed at the color filter 4 so as to be adjacent to the inner peripheral parts and outer peripheral parts of the bonding resin 5. Even if the bonding resin 5 is partially expanded by the formation of such grooves 7, the bonding resin 5 flows into the gooves 7, by which the protruding of the bonding resin 5 to a display area or to the outer side of a pair of the substrates 1, 2 is prevented.  The narrowing of the buffer regions is consequently made possible and the formation of the liquid crystal display device to the narrower picture frame is made possible.
