Hello Everyone
First of all, I'm a french native, so I'm sorry for my mistakes.
I'm not following any electronic class. I'm making a project in my Physic Electricity class.
I chose this diagram:

I finished the 'Time clock A'.
Because I was too easy, my teacher gave me some problem to solve. First, he gave me a Crystal oscillator of 10 MHZ instead of 1MHZ, it was not a problem, I just put a 74HC390 in the diagram, using only the first part. I have the good signal, but the part with the gates, it's the part I don't understand. I know what's a gate, but not the effect. I asked my teacher, but he doesn't know. This is why I'm asking you.
So the questions are:
What is the use of the gate part.
And
Do I need to connect the end of my new 390 to another gate (74HC32), then to the 74HC08?
Francis.
