摘要： A flyback power converter includes a transformer for transferring an input voltage from a primary side to a secondary side. The secondary side includes a main output voltage loop and at least one auxiliary output loop connected with a magnetic amplifier. A pulse width modulation (PWM) controller controls a switch on the primary side of the transformer for turning on the switch and turning off the main output voltage loop and the auxiliary output voltage loop for storing a magnetizing energy on windings of the secondary side. The PWM controller further turns off the switch and turning on the main output voltage loop for providing a main voltage output and for magnetizing the magnetic amplifier connected to the auxiliary output voltage loop. The magnetic amplifier functioning as an auxiliary-loop switch for turning on the auxiliary output voltage loop when the magnetic amplifier is saturated with magnetization and turning off the main voltage output voltage loop for providing an auxiliary output voltage. A time-shared energy transfer mechanism is provided between the main output voltage loop and the auxiliary output voltage loop to fully utilize the entire duty cycle.

摘要： It is difficult to efficiently fabricate optical lenses on which gradation coloring is finely implemented. Gradation coloring is implemented on optical lenses by using an optical lens coloring system having an optical lens holding device for holding an optical lens, a coloring agent discharging device provided with one or a plurality of nozzles for discharging coloring agent for coloring the optical lens, and a relative position control device for controlling a relative position of the optical lens holding device and the coloring agent discharging device. The relative position control device controls the relative position of the optical lens holding device and the coloring agent discharging device such that coloring agent discharged out of the coloring agent discharging device arrives at a predetermined plane substantially from a direction normal to a predetermined plane of an optical lens held by the optical lens holding device.
