Abstract: PURPOSE:To uniformly form an rugged plated layer having superior adhesion on a body to be plated, by periodically reversing the positive and negative polarities of a pair of copper electrodes in an electrolytic circuit formed separately from an electrolytic circuit for rugged copper plating. CONSTITUTION:A copper sulfate plating soln. 9 contg. Cl<-> at a low concn. and a polyoxyethylene surfactant is used for plating. The surfactant forms a complex of C<+> and the Cl<-> contributes toward forming a moderately uneven plated copper layer.

Title: Interface circuit
Inventor: MASUDA WATARU
IPC: H03K19/018
Filed: 1980-04-13
Abstract: PURPOSE:To achieve the high-speed operation of initial-stage integrated injection logic (I<2>L) by charging initial-stage I<2>L with an injector current and a current from an interface circuit. CONSTITUTION:When signal (c) is applied to base C of transistor 11 and potential Vc at base C decreases below potential VE at base E of transistor (TR)12, TR12 turns off and TR11 turns on. The collector current of TR11 permits the base  potential of TR13 to rise and TR13 turns on. Then, TR13 draws in an injector current and the charge of input capacitor 4 to cut off inverter 3. When potential Vc at base C rises above potential VE at base E, on the other hand, TRs 11 and 13 turn off and TR12 turns on. The collector current of TR12 charges input capacitor 4 of initial-stage I<2>L together with the injector current to turn on inverter 3.

Title: Semiconductor laser device
Inventor: HASHIMOTO MASAFUMI
IPC: H01S5/32
Filed: 1979-04-18
Abstract: PURPOSE:To prevent degradation of service life by a method wherein an epitaxial layer with hetero-bonding containing active layers is formed on semiconductor substrates comprizing approximately (100) surfaces and is cut open in parallel with largely uneven stripes having steps among two kinds of stripes group occuring on the substrates so as to ensure obtaining a smooth surface. CONSTITUTION:A n-type GaAs1-xP is overlapped on n-type GaAs substrates comprizing approximately 100 surfaces. With a layer 8, the composition ratio x is varied from 0-0.3 sequentially. With a layer 9, x is set to 0.3. On these layers, Ga1-yInyAs1-x Px is overlapped where hetero-bonding is formed as y=0.34, x=0.99 for a n-layer 10; y=0.23, x=0.79 for a n-type active layer 11; and y=0.34, x=0.99 for a P player 12. Ohmic electrodes 13 and 14 are attached to layers 12 and 17. Since a stress caused by difference of grid constants between the substrates and the layer 8 is absorbed, uneven stripes in grid-form occur in the layer 9 in the <110> direction. By making a resonant face A created in parallel to the largely uneven stripes, a flat and even surface capable of being cut open easily is obtained and also longer service life of the device can be ensured because of its homogeneous characteristics.
