Abstract: Disclosed is an inverter system. A control part of the inverter system includes a control unit configured to set a communication protocol in association with a control unit of the power part, and transmit control data and receive power data according to the set communication protocol, and a power part of the inverter system includes a control unit configured to set a communication protocol in association with the control unit of the control part, and transmit power data and receive control data according to the set communication protocol.

Abstract: Disclosed herein is a method for controlling interrupts in an inverter. If a control unit checks that an interrupt is issued in main software while an inverter is operating, the control unit analyzes the type of the interrupt. The interrupt is converted into an interrupt ID sorted by functionality. If the interrupt ID is a previously registered interrupt ID, an interrupt function corresponding to the registered interrupt ID is executed.

Abstract: An exposure apparatus for exposing a photoresist film formed on a semiconductor substrate includes a plurality of reticle stages on which respective reticles can be supported at the same time. The reticles can be selectively and hence, successively, positioned along the optical axis of the apparatus that extends from the light source of the apparatus to a substrate stage. One region of the photoresist film is exposed to light directed through the first reticle. Then the second reticle stage is aligned and another region of the photoresist film is exposed to light directed through the second reticle.
