Definitions

  • a pulse transformer 14 comprises a toroidal magnetic core 15 having a rectangular hysteresis loop as shown in FIG.
  • the closing interval of the rotary switch is shown by 71 of FIG, 8. (In this figure t represents time.) This closing interval is adjusted to be shorter than the interval of the intake stroke but the position of the closing interval in the intake stroke can be ad justed by changing the angular position of the rotating shaft ll with respect to its driving shaft such as the rotating shaft of the distributor or the cam shaft of the engine.
  • L is the inductance of the inductor 26
  • R the combined resistance of the variable resistors included in the circuit under consideration
  • E electromotive force of the dc. source 20.
  • the time when the contacts 12 and 13v close is taken as the origin of the time.
  • the one end terminals of the coils Mia-46x are connected to the minus terminal of the source 47 through the coil 84 of the relay 82 and the class-B contact of the relay 8].
  • the operation of this embodiment is a little inferior in reliability but it would be seen that the equivalent operation as that of the embodiment of FIG. 1 can be carried out with a single grid-controlled rectifying element.
