  • Publication number: 20200321877
    Abstract: A device includes a driving portion, a transformer having a primary winding and a secondary winding, the secondary winding generating an output voltage, the driving portion being connected across the secondary winding so that the output voltage is applied to the driving portion, a switching element connected in series to the primary winding, a first controller provided in a primary side of the transformer for controlling the switching element, and a second controller supplied with the output voltage. The second controller is configured to perform, during implementation of a burst switching control, transmitting a stop signal to the first controller when the output voltage exceeds a first voltage, and transmitting, after transmission of the stop signal, a resumption signal to the first controller when the output voltage falls below a second voltage lower than the first voltage.

  • Patent number: 8340803
    Abstract: The present invention is directed to a technique that avoids occurrence of interference among multiple placement heads, when multiple placement heads simultaneously access a circuit board, and a pallet which is arranged in one direction with respect to the circuit board. When the component placement part 150 having the multiple placement heads simultaneously pick up the components from the pallet 160 and simultaneously place the components on the circuit board, the controller 140 specifies a pair of component groups to be picked up simultaneously from the pallet 160 by the multiple placement heads and places the components on the circuit board, so that an area where the multiple placement heads move in overlapping manner is minimized, and the placement heads respectively pick up the components included in the pair of component groups being specified and place the components on the circuit board.
