This is square-wave signal with a cycle duration of 40- 70 µs and serves to synchronise the step-motor control module L297 (see Fig. 2). Correct ? - N - Check R3, C3 - V2 On R20, R21 /V2/15 a reference voltage of 1.35 V (± 0.06 V) must be measurable. It is generated ...
of copier, a coil 64 of the vibrator 26 is electrically energized through a half-wave alternating current rectifier in sequence with a print light for the copier. However, it should be understood that the energization of the coil 64 can be coordinated with the operation of the copier 12 in...
Figure 4 is an enlarged sectional view on the line 4-4 of Figure 1 illustrating the major portion of the mechanism of my apparatus and the relation of the parts to each other. Figure 5 is a sectional view on the line 5-5 of Figure 4 showing a plan view of a time wave producing ...
