So I came up with this device on my own without looking anything up. (Mainly cause I didn't know what to search for.)
Basically what I've done is make a contraption that pulses one quick redstone signal, only one. Now I'm sure there is an easier way to do this. But this is how I did it....
The white signal is the output.
This uses the fact that items despawn after 5 minutes. Once the item is despawned there will be a quick pulse to open and close the door.
yea this is a combination of a few smple mechanisms. its funny i made this exact thing for a 5 min flip flop circuit that cut water on and off to a structure that i made. if you throw in a fli flop it will turn things on and off every 5 mins.
I see you've discovered the monostable circuit. Because of your first inverter, it is triggered by a falling edge, when the input goes from the on state to an off state. If you remove the inverter and use dust, it will be triggered by a rising edge.
From what I can tell, this outputs a 7-tick pulse. You can adjust the pulse size by altering the timing of the repeaters on the yellow line. With a repeater left at the default of 1 delay, and the other repeater set to a 2-tick delay, this mechanism will output a 2-tick pulse.
This design can't send a 1-tick pulse, as that will turn the piston into a block dropper. I'm going to go take a few screenshots and show you a few designs that are easier and more compact. That also have the ability to send a 1-tick pulse.
EDIT: Here they are, all set up to output 1-tick pulses, but easily adjustable.
^^^ Rising edge triggered
^^^ Falling edge triggered
Okay, this next one is a bit weird and buggy. It can send a 1-tick pulse as a falling edge design, but only a 2-tick pulse as a rising edge design.
^^^ Rising edge triggered. I know, it makes no logical sense, but it works. Outputs a 2-tick pulse.
^^^ Falling edge triggered. Outputs a 1-tick pulse.
I could also show you some dual-edge monostable circuits if that sounds like something useful. They activate on both the rising and falling edges of a signal. They are commonly referred to as zero crossing detectors.
dang nose job beat me to it.. yea. its a falling edge detector since it outputs when the signal goes from high to low. as opposed to a rising edge detector. which does the opposite. they can be very useful.

Ok so I used the first picture that you showed and it work quite well. It's silent which is good. This is all for the adventure map I'm making. If you would like to join my world sometime to take a look and maybe give me a few pointers that would be great!

Sure, why not, go ahead and add me. I'm rarely on Xbox Live, but I'm always checking up on the forums. So any time you're having trouble and I'm not on XBL, just quote me or send me a PM telling exactly what you want the mechanism to do and I can probably figure it out. Redstone is literally the only reason I play Minecraft, so I'm fairly decent with contraptions.

You don't even have to attach anything. Lose the dust used as the output, place a torch under the spot the piston extends the block. Then scrap the repeaters in the yellow line, add an inverter to that line, set one in the green line to a 3-tick delay, connect the yellow line to the inverter at the end of the green line, sending a 1-tick pulse, turning the piston into a block-dropper. Boom... T flip flop.
I was going to mention that in my first post here, but I completely forgot.

If you have any questions feel free to ask.
BTW this was done on MCXBLA.
