The compositions as described are stable on storage in the absence of air, are activated by exposure to air, and will then cure in either the presence or absence of air.

Title: Edge detector and pulse generator of digital signal
Inventor: JO JONG-SHIK
IPC: H03K5/00
Filed: 1992-07-03
Granted: 1995-02-24
Abstract: The circuit automatically generates the synchronous pulse according to the logic level after detecting the signal edge and signal transition. The circuit comprises; a falling edge delay unit (11) connected with the signal input line; a rising edge delay unit connected with the signal input line; a first D flip-flop connected with the falling edge; a second flip-flops (13,14) connected with the rising edge and a clock input terminal (CK2); a logic product unit (15) connected with the non inversion outputs of the first and second flip-flop; a pulse generator (16) connected with the preset terminals (PR1,PR2) of the first and second flip-flop; a second inverter (12a) connected with the rising edge unit (12); a third inverter (12b) connected with the second flip-flop.
