摘要:
The present invention relates to a surface mounting crystal oscillator in which an IC chip, a crystal element, and a circuit component are connected together by wire bonding and are housed within a main container having a concave section. The main container has a pair of opposing inner wall step portions along both sides in the longitudinal direction, and this pair of inner wall step portions are also each divided into an upper step portion and a lower-step portion of different heights along the longitudinal direction. At least one of the upper step portions of the pair of inner wall step portions supports one end portion in the lengthwise direction of the crystal element so that the lengthwise direction of the crystal element is aligned in the widthwise direction of the main container. The circuit component is disposed on an inner base surface of the main container below the crystal element. In addition, the IC chip is disposed on an inner base surface of the main container that is formed between the pair of lower-step portions of the pair of inner wall step portions, and bonding wires from the IC chip are connected to those lower-step portions. The present invention provides a highly-reliable surface-mounting oscillator with small dimensions in plan view and heightwise, which is particularly suitable for voltage control.

To provide a light fixture control system with which an inrush current is prevented at the time of motor activation, and a light fixture is prevented from rapidly dimming. In a vehicle including a light fixture to be driven by an output of a generator of the vehicle, and a motor to be driven also by the output of the generator, when the light fixture is driven, the driving current F1 to the motor is duty-controlled.
