Title: Method for supplying metallic ion to plating solution
Inventor: MIZUTA TAMOTSU
IPC: C25D21/14
Filed: 1994-05-31
Abstract: PURPOSE:To supply Zn ion by forming Zn ion for supplying to a sulfate bath Zn based plating solution while keeping pH to a specific value to dissolve metal Zn at a stable rate. CONSTITUTION:Zinc ion is formed by dissolving metal Zn while keeping the pH of a dissolving solution used therefor to <=2.1 and is supplied to the sulfate bath Zn based plating solution. The decrease of H<+> ion concn. at the boundary of metal Zn grain by the reaction of the metal Zn with sulfuric acid at the time of supplying Zn ion results in the increase of pH. As a result, Fe<3+> ion forming a hydroxide at a relatively low pH among the metallic ions contained in the plating solution is allowed to react with OH<-> ion to form ferric hydroxide and the metal Zn 30 is covered with the ferric hydroxide 32. Thus the reaction rate of metal Zn with sulfuric acid is rapidly decreased and is apt to reach 0 in a short time. Then, the purpose is attained by keeping the pH of dissolving solution to the fixed value.

Title: Logic gate
Inventor: NAGAMATSU TORU
IPC: H03K19/08
Filed: 1990-05-10
Abstract: PURPOSE:To allow the gate to meet the requirements of high speed operation, low power consumption and full swing of logical amplitude simultaneously by employing a bipolar transistor for only a power supply side, operating a Bi-CMOS only at leading so as to prevent increase in a delay time. CONSTITUTION:When a signal fed to an input terminal IN changes from a level '1' to a level '0', a PMOS transistor(TR) 11 is turned on and NMOS TRs 12, 13 are turned off. Thus, a current is supplied to a resistor 16 and a base of an NPN bipolar TR 14. In this case, a voltage difference is produced across the resistor 16 and the TR 14 is turned on because a base-emitter voltage of the TR 14 rises. As a result, the load capacitor is quickly charged by an emitter current of the TR 14 and a signal of level '1' is outputted to an output terminal OUT. In this case, since the base and the emitter of the TR 14 is connected through a resistive element, a level '1' is swung fully up to a power supply voltage VDD fed to the source.
