I need help with a school project for science. I need to create a model submarine that floats for 1 minute, sinks to the very bottom of the tank and then comes back up. It doesn't have to look nice, just work. It can not be directly pulled up or down

Hi all! i'm willing to know about the nim to ttl circuit..here i have its website address:

http://lyoinfo.in2p3.fr/cms/cmsecal/TTL_NIM%20user%20manual_v10.pdf

I'm doing the part of 2.2.Since the codes of the components aren't very clear, so i cant find the exactly components of the circuit..and i have to built the circuit in Multisim after i found the exactly components to test it.so the components that i found must be matched with the code of components in multisim,or else it cant be use.

1) Anybody can tell me what exactly are they for those components?
2) Now i roughly know the second component is a ttl(7486N),and the third component(from the left) is octal 3-state buffer(DM74LS244),and the first one is an op-amp..Is it correct?
3) How large of capacitance for the polar-capacitor for this circuit roughly?
4) Where can i get the input for NIM?
5) Anybody can tell me what is NIM signals and TTL signals?

THANK YOU^^
