The chart shows a Schmitt trigger with adjustable threshold voltage composed of 555 time base circuit and RA, RB, RP. It could be viewed as the Schmitt trigger circuit driven by comparator. The output has two ports: One is the rectangular pulse output by pin 3; the other one is the discharging wave (external capacitor) output by pin 7 of the discharging end.
