I would start with two oscillators. One of the oscillators would generate a sinewave, the other would generate a square wave. Then I would add an integrator to get the triangle wave. Last I would add a gating circuit to turn the square wave and triangle wave into pulses. You many need to use more than an LM318 to accomplish this task.

thank you very much for replying but the lm318 opamp can be used as an integrator?,and to generate the sin wave i will make a wien bridge oscilator using lm318?

Essentially yes, although LM318 may need some compensation caps
applied per datasheet. Its a faster and trickier OpAmp to work with
especially in a bread board due to stray inductance and capacitance
in lead lengths.
