Title: Potassium ion removing agent
Inventor: NAKAJI SHUHEI
IPC: B01J39/04
Filed: 1991-10-17
Abstract: PURPOSE:To enable the removing of potassium ions by using a sodium salt type cation exchange resin and a potassium salt type cation exchange resin mixed in a specified range of ratio to keep the density of potassium ions in blood constant when the density of potassium ions in the blood is increased. CONSTITUTION:90-98 pts.vol. of a sodium salt type cation exchange resin is mixed with a potassium 10-2 pts.vol. of a calcium salt type cation exchange resin. When the density of potassium ions rises in blood in an emergency treatment of wounds or the like, the blood is circulated outside a human body and excessive potassium ions are removed by the cation exchange resin with an ion exchange between the ions and sodium ions. Thus, when the density of potassium ions in the blood rises, the excessive potassium ions are removed without changing the density of the potassium ions thereby keeping the density thereof at a proper value.

Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To improve reliability of electrical connection between pads, by reducing occurrence of voids in solder at the time of connecting a flip chip by appropriately setting the plating thickness of a ceramic wiring board. SOLUTION: Metallized layers 4 which become pads 11 when the layers 4 are connected to via holes 3 are formed on one main surface of an alumina ceramic board 2 by simultaneously baking the layers 4 with the board 2. Then the pads 11 are formed by coating the layers 4 with plated-nickel layers 5 having thicknesses of 2.5-8 μm and the layers 5 with plated-gold layers 6. Consequently, the base metallized layers 4 of the pads 11 formed on a wiring board 1 are nearly completely coated with the plated-nickel layers 5. Therefore, the reliability of electrical connection between the pads 11 can be improved, because occurrence of voids in a solder connecting the pads 11 to each other can be reduced after a flip chip of an integrated circuit chip is connected without causing peeling of the metallized layers 4 nor cracks between the layers 4 and the board 2.
