Title: Method and apparatus for metal plating
Inventor: OOTSUBO TAKASHI
IPC: C25D5/00
Filed: 1982-11-02
Abstract: PURPOSE:To perform excellent plating while inhibiting the accumulation of multivalent ions, by performing said plating while reducing more multivalent metal ions in a plating solution with hydrogen activated by a hydrogen-occlusion alloy coated with a platinum or copper-group element. CONSTITUTION:One surface of a plate made of a hydrogen-occlusion alloy comprising Mg2Ni or the like is coated with a platinum or copper-group element, e.g. a Pd alloy or platinum black. Said coated surface is brought into contact with a plating solution, while the other surface is brought into contact with H2 gas, to inhibit the inactivation of the hydrogen-occlusion alloy caused by the contact with the plating solution. Thereafter, more multivalent metal ions such as Fe<3+> existent in the plating solution containing metal ions are brought into contact with said coated hydrogen-occlusion alloy. Hence, the more multivalent metal ions are reduced with hydrogen activated by said hydrogen-occlusion alloy to inhibit the accumulation of the multivalent ions in the plating solution, and the metal plating can be easily stably performed at a low cost.

Abstract: PURPOSE:To obtain a simple, small-sized carrier supplying circuit without providing a high-quality varactor diode, crystal oscillator, etc., by inputting the output of a main oscillator which generates a reference signal to plural automatic frequency control circuits equipped with cutoff circuits. CONSTITUTION:The main oscillator 1 generates and applies a signal of reference frequency which is a common measure of a necessary carrier frequency to plural automatic frequency control circuits 7-1-7-n equipped with cutoff circuits.

When the flag (g') is turned off, the inputted value (h) is used directly as the reproduced pixel value. The reproduced pixel value of the same position as the preceding screen is outputted from the medium 11, when the flag (g') is turned on.

Title: Parity counter circuit
Inventor: KOYAMA YUICHI
IPC: H04L1/00
Filed: 1991-08-02
Abstract: PURPOSE:To reduce the scale of a parity counter circuit by simplifying the constitution of this circuit. CONSTITUTION:When an initial setting signal 105 is kept at logic '0' in a single cycle of a clock 101, the output of a buffer 2 is set at a high impedance. As a result, a signal 106 supplied to one of both input terminals of an exclusive OR circuit 3 is always equal to logic '0' by the function of a resistance 4. Therefore the output signal. 102 of the circuit 3 is decided by a data signal. 107 only and never receives the influence of the counting result obtained in 8 parity counting section preceding by a stage. In other words, a counter 1 is initialized when the signal 105 is set at logic '0'. At the same time, a parity counting operation is started again. As a result, the counter 1 can be initialized without using a conventional complicated circuit that produces a signal to reset a flip-flop 1 even though the parity counting sections are continuous.
