Abstract: A substrate processing device according to an embodiment of the present invention includes a disk part disposed in a chamber in which a heating means is provided, and a pocket part installed on one surface of the disk part and on which a substrate is seated. A heat hole through which heat generated by the heating means passes may be formed on an installation surface of the disk part on which the pocket part is installed, or a gear hole through which the heat of the heating means passes may be formed in a pocket gear facing the disk part.

Abstract: A mobile terminal including a user input unit configured to input information into the mobile terminal; a display unit configured to display data; a Wi-Fi module configured to provide an Access Point (AP) function such that an external terminal can access a wireless network through the Wi-Fi module providing the AP function; and a controller configured to control a state of the Wi-Fi module to be switched between 1) a power saving mode in which the Wi-Fi module is alternated between a sleep state and an awake state and 2) a power saving off mode in which the Wi-Fi module is continuously maintained in the awake state until a Wi-Fi connection request signal is received from the external device or a predetermined amount of time passes from a specific timing point.

Abstract: A mobile communication terminal and multicasting method using the same are disclosed, by which an inter-multiuser multicasting function can be performed without using an access point. The present invention includes a user interface unit, a multicast group management module managing subscriber information based on information delivered via the interface unit, the multicast group management module playing a role in generating and transferring a multicast packet, an internet multicast protocol module delivering a message for joining or leaving a specific group according to a control signal provided by the multicast group management module, and a wireless LAN driving unit performing a multicast traffic action of transmitting the message provided by the internet multicast protocol module in a packet format to a joining group terminal by an ad-hoc system and delivering a packet received from a group terminal to the internet multicast protocol module.
