Abstract: The inventive concept provides a substrate treating method. The substrate treating method includes taking in a substrate to a treating space to mount on a support unit; upwardly moving the support unit after mounting the substrate on the support unit; determining whether the support unit moves normally after the upwardly moving the support unit; and treating the substrate by generating a plasma in the treating space, and wherein at the determining whether the support unit moves normally, before the plasma is generated at the treating space at the treating the substrate, whether a pulse distance matching a predetermined distance data according to a pulse value of a driving unit which pulse-moves a moving body which moves the support unit in a top/down direction, matches a movement distance of the moving body is determined, and an interlock is generated if the pulse distance and the movement distance is different.

Abstract: A hinge apparatus for a mobile terminal, and more particularly, to a hinge apparatus for a mobile terminal is provided, which prevents a hinge from overlapping when a housing is folded to optimize the application of space in a display region and a keypad region and realize a miniaturized and slim device.

Abstract: The cellular phone of the present invention includes a display device provided on the front surface of a main body, and a cover movable relative to and preferably, rotatably mounted on, the main body and having keypads provided on the front and rear surfaces thereof, respectively. A plurality of number keys for a mobile communication are preferably arranged on the keypad provided on the front surface of the cover, and a plurality of character keys for the Internet are preferably arranged on the keypad provided on the rear surface of the cover. Also, another keypad wherein keys for the mobile communication and the Internet are arranged may be provided on the main body. The cover may be in the form of a flip or folder. The cover may have an area smaller than the main body or a window so that a portion of the display device is exposed even when the cover is closed.

Abstract: A power supply apparatus and method of supplying power to a mobile communication terminal are disclosed. When a battery's power for a communication module is used up, power from a battery for a personal digital assistant (PDA) module is supplied to the communication module to allow further use of the communication module. When the remaining capacity of the battery for the PDA module goes to a level of at which the PDA module is not operable, the power supply to the PDA module can be discontinued and power can be supplied to the communication module. Thus, call service can be continuously provided, even at lower battery power levels, to a user of the mobile communication terminal.
