The XIR element stands for Resistor array and is actually more of a electrical low level building block for an analog computer. It has a number of inputs with different weights which are translated to currents at the summing junction. This way, you can extend Integrators, Summers or Inverters with more inputs. To do so, just connect the summing junctions of the respective elements.
The picture to the right is from an older version of THAT. The current THAT version doesn't have a 0.1 input. However if you need a 0.1 input, you can connect your input signal via a 10 MOhm resistor to the SJ input, or alternatively via a 9 MOhm resistor to a "1" input.
