    Abstract: A parallel circuit of a capacitor and a switching element is connected to a hot cathode discharge lamp lighting device using a high frequency and high voltage generating means for permitting the flow of current into the filaments of the hot cathode type discharge lamp only at the lamp starting time. The switching element of the parallel circuit is a current controlled resistance element, such as a switching semiconductor, having a break-over voltage V.sub.BO lower than the capacitor terminal voltage during the initial ignition period and higher than the capacitor terminal voltage during the reignition or operation period, whereby the filament current to the discharge lamp may be used for preheating of the filament in the initial ignition period. The filament current may be stopped or reduced by turning off of the switching element by raising the terminal voltage of the capacitor in the reignition period during normal operation. Thus, the lumen-per-watt efficacy of the lighting device is improved since the filament current is substantially eliminated during the lamp operation. After the initial ignition period it is preferred to use the capacitor of the parallel circuit as an intermittent commutation capacitor in the high frequency and high voltage generating oscillation circuit having an oscillation capacitor, a nonlinear inductor and a thyristor.

    Abstract: In a sensorless multiphase dc motor which is started by repeating a sequence of steps in order to supply the stator with a series of discrete currents for rotating the rotor in a desired direction, the start-up sequence has a step(s) of conducting a magnetizing shift action by changing the flow of current from one direction to the reverse direction or vice versa thus reducing its time consumption and also, each of the plural phase coils is energized with a high amplitude of current to produce a higher torque thus enhancing the start-up characteristics of the motor.In particular, the magnetizing shift action from one direction to the reverse direction or vice versa is conducted multiple times in each of the plural phase coils during the start-up sequence and the start-up sequence itself is repeated multiple times. As the result, the start-up characteristics of the motor will be more enhanced.
