Title: Copper alloy material for electronic equipment
Inventor: YAMAMOTO YOSHINORI
IPC: C22F1/08
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To produce a material having high strength and excellent in electric and thermal conductivity by limiting the chemical compsn. of a Cu-Ni-Si alloy material and the ratio of Ni/Si. SOLUTION: This material has a chemical compsn. contg., by weight, 1.0 to 5.0% Ni, 0.2 to 1.0% Si, 0.1 to 5.0% Zn, 0.003 to 0.3% P, and the balance Cu with inevitable impurities, and in which the weight ratio of Ni/Si lies in the range of 4.5 to 5.5. The reason why the ratio of Ni/Si is limited is that, in the case the precipitation of Ni2 Si as a solid solution element sufficiently occurs, the amt. of Ni or Si present excessively is reduced. Zn is added for improving its boundary peeling properties at the time of soldering. P is added as a denoxidizer for preventing an adverse influence thereon caused by the oxidation of Si at the time of alloy casting. In the case the material having the above composition is subjected to aging treatment under prescribed conditions by two stages, the one having >=720MPa tensile strength and >=48% IACS electric conductivity can be obtd.

IPC: G11C11/34
Filed: 1983-03-09
Abstract: PURPOSE:To attain low power consumption by flowing a current to a selected decoder circuit only so as to flow sufficiently the current thereby attaining high speed. CONSTITUTION:A coincidence circuit 35 consists of a pnp transistor TR and resistors RE, RC in this example. The signal level of a row and a column output is selected that the pnp TR at the cross point is not turned on when one or both of the row and column is at the selected level but turned on when both the row and column are at the selecting level only. In setting an output level of a buffer circuit, only the pnp TR at the cross point between the selected row and column is turned on. The current flowing to the TR turned on depends on the signal level of the row and column and the resistor RE. Thus, the output of the selected coincidence circuit is at high level and the output of all other coincidence circuits is at low level.
