    摘要: A vehicle discharge lighting unit can include a bulb mounting slot provided in a resin base. The mounting slot has a channel diameter that fits with an outer bulb of a lamp. A flange can be provided for mounting the resin base to a reflector. A burner band mounting section of the base can extend towards the lamp along a discharge chamber direction and project within the reflector. The driver case can also be separated into a front case and a rear case. The resin base and the driver case can therefore be most appropriately shaped while also having improved dielectric strength. When either of the base or the driver case is defective, only the part that is defective needs to be replaced.

    摘要: In an oscillation control apparatus for an ultrasonic oscillator, an FET circuit is connected to an oscillation circuit for varying a resistant value of a resistor unit of the oscillation circuit, which determines a free-running frequency thereof. A phase-difference detecting circuit is provided for detecting a relative phase difference between voltage and current in the ultrasonic oscillator. A threshold discrimination circuit outputs a signal when the phase difference inputted from the phase-difference detecting circuit exceeds at least a predetermined value. A pump circuit integrates the signal from the threshold discrimination circuit. A resistant value of the FET circuit varies when an output signal from the pump circuit exceeds a predetermined value.
