This powder-classifying apparatus has: a centrifugation chamber configured so as to be sandwiched between two opposing members; an air supply unit that supplies air into the centrifugation chamber and generates a swirl flow; a raw material supply unit that supplies raw-material powder into the swirl flow; a fine powder recovery unit having an opening part through which air that includes fine powder classified within the centrifugation chamber is ejected to outside of the centrifugation chamber; a coarse powder recovery unit provided to the outer edge part of the centrifugation chamber, for ejecting classified coarse powder to outside of the centrifugation chamber; and an annular slit provided to at least one of the members that constitute the centrifugation chamber, the slit being provided in a region between the center part of the centrifugation chamber and the outer edge part.

Powder classifying apparatus

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.

Surface mounting crystal oscillator

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 Fto the motor is duty-controlled.
