Abstract: An air conditioner having an indoor unit and an outdoor unit, at least one of which includes a communication unit, a switching unit turned on when communication lines are connected to the communication unit, turned off in a standby mode, and turned on when the standby mode is released, a voltage distribution unit distributing voltage applied to the communication unit when the switching unit is turned off, a voltage adjustment unit adjusting the voltage applied to the communication unit and transmitting the adjusted voltage to the communication unit, and a control unit turning the switching unit on when driving voltage is input to the control unit, turning the switching unit off when the at least one of the indoor unit and the outdoor unit enters the standby mode, and turning the switching unit on based on the voltage distributed by the voltage distribution unit in the standby mode.

Abstract: A method for preventing process errors in a semiconductor fabricating process allows only a few authorized engineers to release interlocks of semiconductor fabricating equipment when a count of interlock occurrences exceeds a predetermined number within a predetermined period of time. By allowing a semiconductor fabricating equipment operator only limited ability to reset equipment interlocks, repeated interlock conditions caused by test specification failures may be over-ridden only a predetermined number of times before the semiconductor fabricating equipment is disabled completely. The disabled semiconductor fabricating equipment may only be re-enabled using an authorization code, which is only made available to selected personnel, thereby ensuring that necessary repairs and corrections have been implemented on the semiconductor fabricating equipment.
