Title: Sulfurization coloring method for copper and copper alloy
Inventor: MORIMOTO KAZUNARI
IPC: C23C22/00
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To stably execute coloring treatment of high performance and high quality even if activating treatment for a copper material is obviated by using a sulfurization coloring soln. contg. potassium sulfide and sodium hydroxide by specified concn. SOLUTION: The copper material as the object may has a planar shape or the other shape such as of an ornament. The sulfurization coloring soln. is composed of an aq. soln. incorporating of potassium sulfide by the concn. of 3 to 20 g/l and sodium hydroxide by the concn. of >60 g/l. There is a need of controlling the pH of the sulfurization coloring soln. to >=14 for imparting the function of removing the factor of inhibiting coloring reaction to the sulfurization coloring soln. By controlling the concn. of potassium sulfide or the dipping time of the copper member into the sulfurization coloring soln., the color tone of black, brown, light brown or the like can be obtd. As to the soln. temp. at which the sulfurization coloring is executed, there is no problem only if it lies in the range from 10 to 60 deg.C. Moreover, there is no occurrence of precipitation in this sulfurization coloring soln. Furthermore, since the decomposing rate of the soln. is slow, the service life of the soln. is prolonged.

Abstract: PURPOSE:To reduce the output low/high propagation time of a switching time as the titled circuit by designing the circuit that a base electric charge of an output transistor(TR) is sucked in the base as a collector current of the 2nd TR connected to the collector of the 1st TR. CONSTITUTION:When a low-level voltage is applied to an input terminal 3, a diode 12 and a TR 13 are conductive, resulting in that a TR 14 is conductive, a base electric charge of a TR 7 is sucked via diodes 17, 18 together with the base electric charge of a TR 8 and the TR 8 is nonconductive. On the other hand, a TR 5 is conductive and TRs 6, 7 are nonconductive, then TRs 9, 10 are conductive, a current flows from a high-potential power supply 1 via a resistor 30 to an output terminal 4, which goes to a high level. Thus, the timing when the TR 8 is nonconductive approaches the timing when the TR 7 is nonconductive and the circuit having short output low/high propagation time as the switching time is obtained.

Title: Differential amplifier
Inventor: MIYAZAKI NOBUYUKI
IPC: H03F3/45
Filed: 1983-06-14
Abstract: PURPOSE:To attain the actuation of a differential amplifier with high sensitivity and at high speed by adding a capacitor between the drain of one side of an FET constituting a flip-flop and a contact between a common source and the drain of a control FET. CONSTITUTION:Nodes 15 and 16 are charged up toward the high potential side and the data is delivered before the signal of a high potential is read out to a data line 15. Then an FET14 is tuurned on when the control signal of a node 18 is changed to the high potential side. Thus a node 17 is changed to the low potential side. The node 16 is connected to the node 17 via a capacity 40 and therefore changes to the low potential side to produce a difference of potential to the node 15. This potential difference is amplified by the flip-flop of a differential amplifier and then latched. If the read-out data has a low potential, the node 15 is varied gradually to the low potential side. When the potential of the node 15 is lowered sufficiently than the potential drop of the node 16 due to the capacity 40, the control signal is raised up to perform differential amplification.
