using as active elements semiconductor devices (H03K4/787 - H03K4/84 take precedence)

Introduced: September 1968

Title

Titles differ between systems:

IPC: using as active elements semiconductor devices

CPC: using as active elements semiconductor devices (H03K4/787 - H03K4/84 take precedence)

Full Title

Full titles differ between systems:

IPC:

Generating pulses having essentially a finite slope or stepped portions > having triangular shape > having sawtooth shape > using as active elements semiconductor devices

CPC:

Generating pulses having essentially a finite slope or stepped portions > having triangular shape > having sawtooth shape > using as active elements semiconductor devices (H03K4/787 - H03K4/84 take precedence)

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
